Effectiveness of #Diphtheria and #Tetanus Toxoids and Acellular #Pertussis #Vaccine in #Children Aged 6 Months–6 Years During a Statewide Pertussis Outbreak — #Alaska, May–November 2024

 


Abstract

Widespread use of pertussis vaccines in children has resulted in a >90% reduction in the number of annual pertussis cases in the United States. After a period of low U.S. pertussis incidence during and shortly after the COVID-19 pandemic, incidence increased in 2024. Data on the real-world effectiveness of diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP) against pertussis during this disease resurgence are limited. In response to documentation of a record high pertussis incidence in Alaska during May–November 2024, DTaP vaccine effectiveness (VE) against pertussis in Alaska children aged 6 months–6 years was evaluated. Adjusted VE was 96.2% among children who had completed the 3-dose primary DTaP series and 85.3% among those who were partially vaccinated. Compared with children who had received ≥3 DTaP doses, the odds of laboratory-confirmed pertussis were approximately 26 times as high in unvaccinated children (adjusted odds ratio [OR] = 26.1), and approximately 4 times as high in those who had received 1–2 DTaP doses (adjusted OR = 3.8). These findings reinforce the importance of following pertussis vaccination recommendations to protect for children from the disease and reduce the occurrence of pertussis outbreaks.

#WHO urges #vigilance after #Kenya confirms second #Ebola case (UN News Centre, Oct. 15 '26)

 


    The patient, a 39-year-old man, is a relative of Kenya’s first case – related to the ongoing deadly outbreak in the Democratic Republic of the Congo (DRC) – who died in hospital on 5 October. 

    He was among contacts who were placed in quarantine and developed symptoms on 13 October. 


‘We all have a role to play’ 

    “I congratulate the Government for taking this important step to ensure that contacts are listed and quarantined,” WHO Representative Dr. Neema Rusibamayila Kimambo told UN News in Nairobi, a day after the Ministry of Health confirmed the new case. 

    “But to defeat this disease, it's not about the Government, it is not about partners It is about everybody,” she insisted. “We all have a role to play and if each one of us plays our part, then we should be able to contain the disease and stop community spread.” 


Casting a wide net 

    Kenya’s first Ebola patient and fatality was a local man who had been living in the DRC, where the record outbreak continues to spread in the east. 

    He arrived in Nairobi via Uganda on 3 October and died in hospital two days later. 

    Dr. Kimambo commended health authorities who “cast the net very wide” to identify people who had come into contact with him – whether in the air or on the ground. 

    The more than 40 people included airline passengers and crew, airplane cleaners, airport workers, baggage handlers and immigration officials, as well as health personnel and family members.  

    Most are in quarantine, while a few low-risk contacts have self-quarantined and are being monitored. Meanwhile, every effort is being made to reach six passengers who have been difficult to locate because they have foreign phone numbers. 


Stepping up preparedness

    Even before the first case , WHO and the Kenyan Government were stepping up Ebola preparedness after the outbreak was declared in the DRC in May. Neighbouring Uganda also confronted the disease, with any outbreak officially ruled out in late August. 

    Teams are working across all areas, including surveillance and contact tracing.  WHO has also brought in a senior incident manager who participated in the Ebola response in Uganda, as well as other experts. 

    “We are building on the work that we started during the preparedness phase, so case management and IPC (infection prevention and control) are critical at this time in the quarantine centres,” Dr. Kimambo said. 

    WHO also continues to provide assistance to Kenya in various other ways. The UN agency has donated some $70,000 worth of supplies, including IPC and laboratory items, since the first Ebola case was identified.  

    Additionally, more than 4,000 health workers have been trained, including for screenings at ports of entry. 


Keep borders open

    While Dr. Kimambo said there still is no need to impose travel restrictions or close national borders, she underlined the importance of appropriate screening to identify travellers who may pose a health risk. 

    Preventing Ebola begins with understanding how the disease is transmitted, she said, which is through contact with the bodily fluids of an infected person.  

    She reiterated the advice to practice regular handwashing, use hand sanitizer and avoid shaking hands. 

    As Ebola symptoms include fever, vomiting and diarrhoea – which mimic symptoms of malaria and other diseases – she stressed the need to seek medical care quickly. In the interim, Kenyans are urged to keep calm and stay safe. 

    “I think one is not to over panic and be very fearful because we do not have community spread,” she said.  “But two, let us be responsible. Whoever is sick, let’s make sure we go to a health facility and get care.  And also, let us ensure that we take IPC measures.”

#Epidemiology and #Economic Burden of #Puumala Virus #Infection in Styria, #Austria, 2003 to 2024

 


Abstract

Background

Hantavirus infections cause hemorrhagic fever with renal syndrome and impose a potential burden on healthcare systems. However, comprehensive economic data remain scarce. We quantified the inpatient economic burden of hospitalized patients with Puumala virus (PUUV) infections in Styria, Austria’s primary endemic region, to identify hospitalization costs and early admission predictors of costs.

Methods

This retrospective cost-of-illness study analyzed 1049 serologically confirmed PUUV hospitalizations across 20 public hospitals in Styria, Austria between September 2003 and March 2024. Costs were estimated using the Austrian performance-oriented hospital financing (Leistungsorientierte Krankenanstaltenfinanzierung) diagnosis-related group system, standardized to 2024-equivalent Euros using consumer price index deflation. Admission predictors of cost were assessed using multivariable γ-generalized linear modeling with multiple imputations. Temporal trends in length of stay were analyzed using weighted segmented linear regression.

Results

Cumulative inpatient cost was ∼€10.3 million (mean per-case: €9788) for the entire study period of 21 years. Three epidemic years (2012, 2019, and 2021) accounted for 53.6% of cases and over €5.2 million in expenditure, with peak annual costs reaching €1.93 million (0.274% of total Styrian inpatient expenditure) in 2012. Prolonged activated partial thromboplastin time (aPTT; cost-ratio 1.024 per second, 95% CI 1.019–1.030) and older age (CR 1.004 per year, 95% CI 1.001–1.008) were independent admission-level predictors of higher cost. Median hospital length of stay declined by ∼50% over the study period.

Conclusions

PUUV hospitalizations impose a sharply episodic but recurrent economic burden on regional healthcare systems. Admission aPTT and age independently predicted cost, but clinical outcomes were not modeled and these variables do not constitute a triage tool. Epidemic preparedness strategies are warranted.

Evaluating the effects of #population #mobility on #transmission during the #COVID19 #pandemic

 


Abstract

Changes to community mobility during the COVID-19 pandemic, together with unprecedented availability of surveillance and mobility data, provide a unique opportunity to quantify the effect of mobility on respiratory infection transmission. We present a renewal model that incorporates epidemiological mechanisms influencing SARS-CoV-2 transmission along with a non-mechanistic scaling process. We compare models with and without mobility using epidemic data from 122 countries and quantify the influence of mobility through reductions in non-mechanistic scaling. In several countries, this non-mechanistic process closely tracks mobility trends and varies substantially less when mobility is incorporated. This is especially evident in Western Europe and North America, but not in several countries of West Africa and the Arabian Peninsula. Google and Facebook data produce similar findings, and parks is frequently assigned the lowest weight in the multi-location Google analysis. Mobility trends are strongly aligned with short-term transmission dynamics in many high-income settings, although between-country heterogeneity remains.

Mice immunized with #N1 NA in a single cycle infectious virus or in a recombinant nanoparticle #vaccine are protected against lethal challenge with HPAI #H5N1 influenza

 


Abstract

The recent spillover of highly pathogenic (HP) H5N1 clade 2.3.4.4b into dairy cattle and other mammalian species has been concerning. Vaccine candidates that can be rapidly synthesized and implemented are key countermeasures for protecting the human population against emerging pathogens. Here we examine the use of a pH1N1 virus lacking the genetic material for hemagglutinin (HA), limiting the infection to a single cycle (sciIAV) or Cobalt lipid-porphyrin nanoparticles decorated with neuraminidase (NA) of HPAI H5N1 (N1-CoPoP) as vaccine candidates. C57BL/6 mice that were inoculated intranasally with a single dose of pH1N1 sciIAV did not differ in serum NA antibody compared to uninoculated mice. However, mice that were inoculated intramuscularly with the N1-CoPoP alone or in combination with pH1N1 sciIAV had increased N1 IgG antibodies. Upon lethal challenge with HPAIV H5N1, all mice inoculated with either pH1N1 sciIAV or N1-CoPoP were protected from weight loss, unlike unvaccinated mice with substantial body weight losses that succumb to viral infection between 7 and 10 days post infection (dpi). Both pH1N1 sciIAV and N1-CoPoP immunization minimized viral infection such that only one mouse receiving pH1N1 sciIAV had detectable viral titer in the lungs at 4 dpi. By 6 dpi, no mouse inoculated with pH1N1 sciIAV and/or N1-CoPoP had detectable virus in nasal turbinates, lungs or the brain, unlike the high viral titers found in uninoculated mice. Both pH1N1 sciIAV and N1-CoPoP were protective and should be investigated further as alternative vaccine candidates.

#Bundibugyo Virus Disease #Outbreak in #DRC - Weekly #Situation #Report 22, Data as of 11 October 2026 (WHO, summary): 9,066 cases and 4,381 deaths

 


{Summary}


{Click on Image to Enlarge}

___


Event description

Democratic Republic of the Congo

    The BVD outbreak in the Democratic Republic of the Congo continues to evolve, expanding both geographically and in terms of the numbers of cases and deaths. 

    The Dakwa Health Zone in Bas-Uélé Province has become the latest  affected health zone, bringing the total number of impacted health zones to 65  across seven provinces since the start of the outbreak. 

    Transmission remains highly heterogeneous across these regions. Since  External Situation Report #21, a total of 463 additional confirmed cases and 233 confirmed deaths have been reported. This increases the cumulative  total to 9066 confirmed cases, including 4381 confirmed deaths [crude case fatality ratio (CFR) 48.3%] as of 11 October 2026.

    Ituri remains the principal focus of the outbreak, though its relative  contribution is declining; it is currently for 73.8% of cumulative confirmed cases. 

    Substantial transmission persist in Nord-Kivu and Haut-Uélé.

    National incidence remains high and fluctuating, with no sustained  downward trajectory evident. Following rapid expansion through July and August,  the epidemic has entered a more heterogeneous phase characterized by repeated declines and rebounds. This pattern reflects asynchronous transmission  across provinces and health zones; declining activity in established Ituri hotspots  is being offset by persistent or renewed activity elsewhere, particularly in  NordKivu, while sporadic detections continue to extend the geographic footprint. 

    The overall trend suggest a shifting and geographically fragmented  epidemic than sustained contraction.(Figure 1)

Trend Analysis (21-day comparison): 

    During the most recent 21- days period (21 September – 11 October  2026), a total of 1333 confirmed cases were reported nationally, compared  with 1633 cases during the preceding 21 days (31 August–20 September). 

    This represents a decrease of 300 cases (−18.4%). Cases declined across  the three principal transmission provinces: Ituri: Decreased from 931 to 748  (−19.7%) accounting for 56.1% of national cases in the latest period.

        • Nord-Kivu: Decreased from 589 to 486 (−17.5%)accounting for 36.5% of  national cases

        • Haut-Uélé: Decreased from 89 to 72 (−19.1%)

    Despite the overall 21-day decline, daily incidence continues to fluctuate, with repeated rebounds, particularly in Ituri and Nord-Kivu.  

    Consequently, these reductions should be interpreted cautiously and do  not yet indicate a sustained contraction of the epidemic (Figure 2).

(...)

    During the same period, 649 confirmed deaths were reported nationally, compared with 782 deaths during the preceding 21 days, representing a decrease of 133 deaths (−17%). 

    Deaths declined from 448 to 377 (−15.8%) in Ituri and from 296 to 230  (−22.3%) in Nord-Kivu. 

    In contrast, deaths increased from 31 to 34 (+9.7%) in Haut-Uélé and  from five to eight (+60.0%) in Tshopo. 

    Consequently, Ituri accounted for 58.1% of deaths during the latest  period and Nord-Kivu for 35.4%, compared with 57.3% and 37.9%, respectively,  during the preceding period. However, as with cases, the overall 21-day decline  masks continued fluctuations in mortality and should be interpreted cautiously, as  it does not yet indicate a sustained downward trajectory (Figure 3).

(...)

    Transmission remained active in more than three-quarters of all health  zones affected since the start of the outbreak.

    Of the 65 health zones affected to date, 50 reported at least one new  confirmed case in the last 21 days. Case incidence increased in 23 health zones  (Figure 4), decreased in 26 and remained unchanged in one, highlighting  substantial heterogeneity in local transmission. The most pronounced increase  occurred in Mandima, Ituri (23 to 199 cases; +765.2%), while substantial  increases were also observed in Mambasa and several health zones in Nord-Kivu, particularly Beni, Mabalako and Oicha.

(...)

    Declines were widespread across Ituri and Nord-Kivu, including several  major transmission hotspots such as Bunia, Katwa, Mangala, Mongbwalu and  Komanda, while particularly marked reductions were observed in Tchomia  (−94.4%) and Isiro (−83.3%).

    The number of health zones with no reported confirmed cases during  the latest 21-day period decreased from 18 to 15.

    These include Ariwara, Aungba, Boga, Damas, Drodro, Kambala and Mahagi  in Ituri; Goma in Nord-Kivu; Dungu and Gombari in Haut-Uélé; Bafwasende,  Lubunga and Wanie-Rukula in Tshopo; Miti-Murhesa in Sud-Kivu; and Buta in  BasUélé.

(...)

    Weekly confirmed deaths ( Figure 5) increased for the second consecutive  week, from 192 during 21 – 27 September to 224 during 28  September – 4 October and 233 during 5 – 11 October. In the latest week, deaths  increased by 4.0%, with community deaths rising from 150 to 157  (+4.7%) and deaths in treatment facilities from 74 to 76 (+2.7%). 

    Community deaths continued to account for approximately two-thirds of all  confirmed deaths, increasing slightly from 67.0% to 67.4%. The sustained  increase in deaths over the past two weeks, particularly the persistently high  proportion occurring in the community, remains a key concern.

(...)


Kenya

    As of 12 October 2026, no new confirmed BVD cases or deaths have been  reported in Kenya since the detection of the imported case, and the  cumulative total remains one confirmed case with one death (CFR 100%).

    The imported case was a 40-year-old Kenyan male who travelled from the  Democratic Republic of the Congo through Uganda before arriving in Nairobi  on 3 October 2026. He presented for care and was isolated on the day of arrival, with laboratory testing confirming Bundibugyo virus infection. He died on 5  October and received a safe and dignified burial on 6 October 2026.

    Contact tracing and monitoring remain ongoing, with 128 contacts  currently listed, comprising 26 passengers, four flight crew, 43  Jomo Kenyatta International Airport staff, 10 relatives and 45 healthcare  workers. 

    Of these, 108 (84.4%) are in quarantine and were successfully followed up,  while 20 remain outside quarantine. The latter group includes seven passengers  who have not yet been located, seven newly identified healthcare workers and  one immigration officer who remains unreachable. 
    
    The remaining five contacts are passengers who had onward travels their  respective destination countries have been notified.

    A total of 289 alerts have so far been investigated, generating 293  laboratory tests, with all 292 results other than the index case testing negative. 

(...)


Situation interpretation

    The fluctuating national trajectory reflects uneven interruption of  transmission across a complex, geographically dispersed and increasingly cross-border outbreak. 

    Although response capacity has expanded substantially, persistent gaps  in early detection, contact follow-up, timely isolation and referral, together with  population mobility, insecurity and variable access to affected communities,  continue to allow transmission chains to persist or re-emerge. 

    The imported case detected in Kenya, following travel from the DRC  through Uganda, underscores the risk of further international spread, although no  secondary transmission has been detected in Kenya to date. 

    Bringing the outbreak under control will require rapid interruption of remaining transmission chains through earlier case detection and isolation,  ≥95% contact follow-up, investigation of community deaths, strengthened IPC  and safe burials, intensified surveillance in emerging hotspots, and rapid  management of unlinked cases, alongside strengthened cross-border surveillance,  information sharing and coordinated contact tracing. 

    Without consistent implementation of these measures across all affected  and at-risk areas, localized gains are likely to continue being offset by renewed  transmission and further geographic spread.

Cross-reactive T-cell responses against #BDBV in #humans after rVSVΔG-ZEBOV-GP #vaccination

 


{Excerpts}

(...)

Our study shows that a single immunisation with the available, licensed EBOV vaccine induces T-cell cross-reactivity against BDBV and to a lesser extent against SUDV. Although it is not known whether these T cells contribute to improved clinical outcomes upon BDBV exposure in humans, preclinical studies show that T-cell responses are required for vaccine-mediated protection in non-human primates: CD4 T cell help to B cells is required for protection against disease caused by EBOV,10 and depletion studies have also shown a protective role of CD8 T cells.11

Our study has limitations. Due to the small sample size and single measured timepoint, dose–response differences and long-term persistence of the cross-reactive T-cell response could not be assessed. This study was performed in healthy adults in Germany, thus representativeness of populations in areas affected by the BDBV outbreak is limited.

Although a correlate of protection against disease caused by BDBV has not been defined, our findings provide first evidence that rVSVΔG-ZEBOV-GP vaccination against EBOV induces BDBV-cross-reactive T-cell responses. In the absence of a BDBV-specific vaccine, these data support the systematic evaluation of the available EBOV vaccine within clinical trials during the current outbreak.

Strong #Protein #Responses to Acute #Infection Control General Post-Viral #Sequelae and #SARS-CoV-2-specific #Neurocognitive Sequelae

 


Abstract

After serious infections, many survivors fully recover while others face persistent symptoms including neurocognitive dysfunction, cardiopulmonary instabilities and disabling fatigue, classified broadly as Post-Acute Infection Syndromes (PAIS). Post-Acute Sequelae of COVID19 (PASC) is one special case. To test whether acute infection initiates PAIS, we analyzed proteins in 173 saliva samples collected during severe respiratory viral infections and tracked patient outcomes for five years. We discovered 44 proteins, all derived from interferon stimulated genes, that respond strongly to acute infection. Rates of post-acute syndromes were similar regardless of infection, but the types of Sequelae differed by virus. High expression of 19 proteins predict low General Sequelae rates across all viruses. High expression of 23 overlapping proteins predict low Neurocognitive Sequelae rates only with SARS-CoV-2 infections. We propose that low expressions of these proteins, which control viral replication, innate immunity, and secondary autoimmunity, combine to precipitate PAIS and PASC.

Serologic #Testing for #MERS #Coronavirus and #SARS-CoV-2 Cross-Reactive Immune Responses, the #Netherlands

 


Abstract

Cross-reactive SARS-CoV-2–specific antibodies could compromise the specificity of MERS-CoV serology, potentially leading to misclassification of infection history. SARS-CoV-2 exposure induced MERS-CoV antibodies primarily targeting the conserved S2 domain, with occasional neutralizing capacity. Combining MERS-CoV S1 binding with neutralization, however, limited the influence of SARS-CoV-2–induced cross-reactivity on MERS-CoV serology.

#Global Genomic #Surveillance of #MERS #Coronavirus

 


Abstract

Middle East respiratory syndrome coronavirus (MERS-CoV) is a persistent zoonotic and epidemic threat. We analyzed 807 publicly available human- and camel-derived MERS-CoV genomes collected during 2012–2024 to assess global genomic surveillance. Most sequences originated from Saudi Arabia and the United Arab Emirates. Major gaps in surveillance persist across Africa and South and Central Asia despite large camel populations, active trade, and evidence of viral circulation. Phylogenetic analysis confirmed predominance of clade B in the Arabian Peninsula and clade C in East Africa, consistent with regional patterns. We identified uneven sampling, incomplete metadata, and long delays between sample collection and public sequence submission, often spanning years. Those limitations reduce the value of genomic data for timely situational awareness. Integrating genomic with population and trade data supports timelier, more representative, and coordinated One Health surveillance for MERS-CoV but reveals major blind spots.

Subacute Sclerosing #Panencephalitis after #Measles #Outbreaks, the #Philippines, 2007–2022

 


Abstract

Subacute sclerosing panencephalitis (SSPE) is a delayed, almost uniformly fatal complication of measles. The Philippines had measles outbreaks in 2010–2011, 2013, and 2018–2019; the last was the largest in the World Health Organization Western Pacific Region. Published SSPE data from the Philippines end in 2015. We reviewed all 20 children admitted with SSPE to a tertiary pediatric hospital in Quezon City during 2007–2022 and estimated year of measles infection. Median patient age was 6.2 years at hospital admission and 0.7 years at reported measles illness. Five (25.0%) of 20 admissions occurred in 2022, and estimated infection dates placed 4 patients within the 2018–2019 outbreak; all were admitted during 2020–2022. Given the multiyear latency of SSPE, additional cases might emerge over coming years. Reported measles history could not be established in one quarter of patients. Strengthened measles surveillance and sustained 2-dose vaccination coverage are needed.

Efficacy, safety, and immunogenicity of a 9-valent vaccine (ExPEC9V) for #prevention of invasive #Escherichia coli disease in older #adults: a phase 3, randomised, placebo-controlled trial (E.mbrace)

 


Summary

Background

Invasive Escherichia coli disease (IED) caused by extraintestinal pathogenic Escherichia coli (ExPEC) can lead to bacteraemia and sepsis. ExPEC9V is a conjugate vaccine targeting nine E coli O-serotypes that account for most E coli bloodstream infections. We aimed to evaluate ExPEC9V for safety, immunogenicity, and prevention of IED caused by ExPEC9V O-serotypes in adults aged 60 years and older.

Methods

In this randomised, double-blind, placebo-controlled, phase 3 study conducted at 332 clinical sites in 20 countries (E.mbrace), we enrolled participants aged 60 years and older in stable health and with a history of urinary tract infection (UTI) within the previous 2 years. Participants were randomly assigned (in blocks of no set size with the use of interactive web response system, stratified by age and presence or absence of risk factors for complicated UTI) 1:1 to receive a single dose of intramuscular ExPEC9V or placebo. Participants, study-site personnel, and investigators remained masked to group allocation throughout the study. The primary endpoint was first IED in blood or sterile sites caused by ExPEC9V O-serotypes in the per-protocol efficacy analysis set (all randomly assigned, vaccinated participants without major protocol deviations); secondary endpoints included immunogenicity assessment in a subset of participants. Safety endpoints included solicited (safety subset), unsolicited (full analysis set), and serious (full analysis set) adverse events. A prespecified futility analysis conducted when at least 40% of the expected 53 IED events had occurred indicated lack of efficacy, leading to early study termination. We present final study results (data up to the date of the futility announcement), when 17 701 of the planned 19 800 participants had been vaccinated. This trial is registered with ClinicalTrials.gov (NCT04899336).

Findings

Participants were enrolled between June 30, 2021, and Feb 13, 2025. Of 18 844 individuals assessed for eligibility, 17 701 were enrolled, randomly assigned, and vaccinated (8858 with ExPEC9V and 8843 with placebo). The per-protocol efficacy included 17 637 participants (8822 for ExPEC9V and 8815 for placebo). There were 24 IED cases (11 in vaccine and 13 in placebo groups) caused by ExPEC9V O-serotypes in blood or sterile sites, yielding a vaccine efficacy of 14·63% (95% CI −106·57 to 65·38), indicating no protective effect. ExPEC9V had an acceptable safety profile, with more frequent low-grade adverse events in the ExPEC9V versus placebo group, balanced serious adverse event distribution among both groups, and no vaccine-related deaths.

Interpretation

In this large phase 3 trial of older adults, ExPEC9V did not demonstrate efficacy in preventing first IED caused by ExPEC9V O-serotypes, despite generating robust and sustained antibody responses. Development of the ExPEC9V vaccine has been discontinued.

#Taiwan, Seasonal #Influenza and #COVID19 #Epidemics - Weekly Surveillance #Report (CDC, Oct. 13 '26): #H1N1pdm09 flu virus and #SARS-CoV-2 PQ.16.1.1 predominated

 


{Excerpts}

(...)

    According to CDC monitoring data, the domestic influenza epidemic is slowing down but is still in its epidemic period. 

    In week 40 (October 4-10), there were 128,847 outpatient and emergency room visits for influenza-like illnesses, a decrease of 8.9% from the previous week. 

    Last week (October 6-12), there were 144 new cases of severe influenza complications (132 H1N1, 10 untyped A, and 2 B) and 46 deaths (all H1N1). 

    Laboratory surveillance data shows that the influenza virus currently circulating in the community is predominantly type A, with type A H1N1 accounting for 91.8%. 

    This influenza season (115-116) saw a total of 149 severe cases (139 H1N1, 9 untyped A, and 1 type B) and 15 deaths (all H1N1). 

    The previous influenza season (114-115) saw a total of 1,887 severe cases (1,259 H1N1, 511 H3N2, 25 untyped A, and 92 type B) and 409 deaths (278 H1N1, 107 H3N2, 12 untyped A, and 12 type B). 

    Among the severe cases, the majority were elderly people over 65 years old (66.3%) and those with a history of chronic diseases (83.6%). 67.1% of the patients had not received the seasonal influenza vaccine. 

    The domestic COVID-19 epidemic is declining. 

    In the 40th week (October 4-10), there were 5,261 outpatient and emergency room visits for COVID-19, a 35.2% decrease compared to the previous week (September 27-October 3). 

    Last week (October 6-12), there were 21 new severe cases and 15 deaths. 

    This quarter (October 1, 2026-September 30, 2027) has seen a cumulative total of 31 severe cases, including 5 deaths. 

    In the previous quarter (October 1, 2025-September 30, 2026), there were a cumulative total of 783 cases of COVID-19 complicated by severe illness, including 173 deaths. 

    The majority of severe cases were among the elderly aged 65 and above (73.7%) and those with a history of chronic diseases (83.0%). 83.8% of them had not received the COVID-19 vaccine this season. 

    In the past four weeks, the most common local variants have been PQ.16.1.1 and NB.1.8.1.
