#Taiwan #CDC issued a #statement regarding journal research on transmission of viruses from farmed #shrimp in #China to #humans (Apr. 18 '26)

 

Recently, online discussions have focused on a study published in the international journal *Nature Microbiology*, which suggests that *Cryptant Dead Noda Virus* (CMNV), found in aquatic animals, may have the potential to spread across species to humans, potentially causing persistent high-tension viral anterior uveitis (POH-VAU). 

The Centers for Disease Control (CDC) stated that currently only China has reported suspected human cases of CMNV, distributed across 18 provinces with high aquaculture activity. 

Major international public health organizations such as the WHO, the US CDC, and the European Centre for Disease Prevention and Control (ECDC) have not reported any CMNV-related cases or listed it as an urgent threat. 

The CDC assesses the risk of domestic transmission as extremely low and will continue monitoring with agricultural authorities.

The CDC further explained that the study infers that human infection with CMNV may be related to handling or consuming raw seafood; however, further evidence is needed to confirm whether this virus has the ability to effectively infect human eye tissue. 

The Taiwan Centers for Disease Control (CDC) emphasizes that there have been no large-scale human outbreaks or community transmission events caused by CMNV globally at present, and there is no evidence of infection through the general consumption of cooked seafood. 

The CDC will continue to monitor relevant international outbreaks, develop human specimen testing technologies and methods, and establish relevant sampling and testing conditions for risk monitoring and early warning.

According to the monitoring of the Animal and Plant Health Inspection and Quarantine Bureau of the Ministry of Agriculture, there have never been any CMNV outbreaks in shrimp farms in Taiwan. 

The CDC's overall assessment is that the risk of domestic transmission is extremely low, but both agriculture and health authorities will continue to strengthen monitoring. 

CMNV has been listed as an emerging infectious disease by the World Organisation for Animal Health, and infection cases have been reported in shrimp farms in China and Thailand. 

The CDC urges travelers to China and Thailand to take special precautions against CMNV, including thoroughly cooking seafood, avoiding raw seafood for high-risk groups (such as those with chronic diseases), wearing gloves when handling raw seafood, avoiding direct contact with raw food if hands are open, and washing hands thoroughly with soap and water after handling to reduce the risk of infection by various pathogens.

#UK, #England: #Antibiotics and MenB #vaccination to be offered to young people in #Dorset following 3 cases of invasive #meningococcal disease (UKHSA, Apr. 17 '26)

 

The UK Health Security Agency (UKHSA) is working with Dorset Council, the NHS and local partners following 3 confirmed cases of meningococcal infection (meningitis) in young people in Weymouth, Dorset.

The cases were confirmed between 20 March and 15 April. All have received treatment and are recovering well. Close contacts of the cases have already been offered antibiotics as a precaution.

Two of the cases attend Budmouth Academy and the other attends Wey Valley Academy. Further information about the signs and symptoms of meningitis has been shared with students and parents of both schools.

Around 300 to 400 cases of meningococcal disease are diagnosed in England every year. These 3 cases have been confirmed as Meningitis B (MenB) and are the same sub-strain type, but a different sub-strain to the one detected recently in Kent.

The 2 cases who attend Budmouth Academy are contacts of each other, but currently no confirmed epidemiological link has been made between these cases and the third individual who attends Wey Valley Academy. This may mean that this strain of MenB bacteria is transmitting more widely among young people in Weymouth. Due to this, and as an additional precautionary measure, antibiotics and MenB vaccination will now be offered to young people currently in school years 7 to 13 (or equivalent), or anyone not in full time education who would be in one of these year groups, who study in or live in the Weymouth, Portland and Chickerell areas of Dorset.

Dr Beth Smout, UKHSA Deputy Director said:

''We are working closely with partners to follow up and offer precautionary antibiotics to close contacts of the cases. However, meningococcal disease does not spread easily, and outbreaks like we have seen recently in Kent are rare. These cases are not linked to the Kent outbreak and it is important to be aware that this outbreak is not on the same scale as we saw in Kent in terms of speed of transmission or severity.

''However, it is possible that we will see further cases linked to these latest cases in Weymouth and we understand that there will be concern among students, staff, parents and the local community as we widen our offer of antibiotics and vaccination. I’d like to stress that this is an additional precaution, and that we’re following national guidelines to reduce the risk of the infection spreading. School pupils and staff should attend school as normal if they remain well.

UKHSA is now recommending a single dose of antibiotics and a meningitis B vaccine be offered to young people who live or go to school in the Weymouth area, as follows:

-- anyone who is a resident in Weymouth or Portland or Chickerell and is in current school years 7 to 13 (or equivalent), or anyone not in full time education who would be in one of these year groups

-- anyone who attends an educational setting in the Weymouth, Portland or Chickerell area and is in current school years 7 to 13 (or equivalent).

This will be offered in stages starting with Budmouth Academy and Wey Valley schools, as the cases attend these settings. Pupils that attend other schools and other eligible children in Weymouth who do not attend school will be invited after the weekend.

Young people under 16 should be accompanied by a parent or guardian who is able to provide consent at the time.

More information on the vaccination schedule will be provided in due course.

Dr Smout added:

''Meningococcal disease can progress rapidly, so it’s essential that everyone is alert to the signs and symptoms of meningococcal meningitis and septicaemia, which can include a fever, headache, rapid breathing, drowsiness, shivering, vomiting and cold hands and feet. Septicaemia can also cause a characteristic rash that does not fade when pressed against a glass. If the disease is suspected, you should seek immediate medical attention as the disease can progress rapidly.

''It’s also important for teenagers to ensure they take up the MenACWY vaccine routinely offered by the NHS – but also to be aware that this vaccine does not protect against Men B, which is why knowing the symptoms and seeking early treatment is so important.

Young people in school years 7 to 13 in Weymouth are strongly encouraged to take up the offer of antibiotics and MenB vaccination and we are grateful to all those involved in our investigations so far for assisting us.

UKHSA and Dorset Council have issued advice to staff, parents and carers at all educational settings in the area.

Anyone who becomes unwell with symptoms of meningitis and septicaemia should seek medical help urgently at the closest Accident and Emergency Department or by dialling 999. Early treatment can be lifesaving. If you’re not sure if your symptoms are serious, use NHS 111 online or call 111 for further advice.

Avian #Influenza #H9N2 - #Italy (#WHO, D.O.N., April 10 2026)

 

Situation at a glance

-- On 21 March 2026, the National International Health Regulations (IHR) Focal Point for Italy notified the World Health Organization (WHO) of the identification of a human case of avian influenza A(H9) in an adult male returning from Senegal. 

- Next generation sequencing confirmed Influenza A(H9N2). 

- According to epidemiological investigations, the patient had no known history of exposure to poultry or any person with similar symptoms prior to the onset of symptoms. 

- Authorities in Italy have implemented a series of measures aimed at monitoring, preventing and controlling the situation. 

- According to the IHR (2005), a human infection caused by a novel influenza A virus subtype is an event that has the potential for high public health impact and must be notified to the WHO. 

- This is the first imported human case of avian Influenza A(H9N2) reported in the European Region. 

- Based on currently available information, WHO assesses the current risk to the general population posed by A(H9N2) viruses as low but continues to monitor these viruses and the situation globally.

Description of the situation

-- On 21 March 2026, the National IHR Focal Point for Italy notified WHO of the identification of a human case of avian influenza A(H9) in an adult male.

-- The patient had been in Senegal for more than six months and traveled to Italy in mid-March. Upon arrival, he visited the emergency department with a fever and a persistent cough.

-- On 16 March, a bronchoalveolar lavage specimen was collected, which showed a positive Mycobacterium tuberculosis result, as well as detection of un-subtypeable influenza A virus. The patient was placed in a negative-pressure isolation room with airborne precautions. He was treated with antitubercular medication and antiviral oseltamivir. By 9 April, his condition was stable and improving.

-- On 20 March, a regional reference laboratory identified the A(H9) subtype, and on 21 March, next-generation sequencing confirmed influenza A(H9N2). Initial genetic findings suggest the infection was likely acquired from an avian source linked to Senegal. Additional samples have been sent to Italy’s National Influenza Center, where further characterization confirmed virus subtype Influenza A(H9N2), with close genetic similarity to strains previously identified in poultry in Senegal.

-- No direct exposure to animals, wildlife or rural environments was identified. There was also no reported contact with symptomatic or confirmed human cases. Further epidemiological investigations on the source of exposure are ongoing.

-- Contacts identified in Senegal were asymptomatic. All identified and traced contacts in Italy have tested negative for influenza and completed the period of active monitoring for the onset of symptoms and the quarantine required by national guidelines. They also received oseltamivir as a preventive measure. 

Epidemiology

-- Animal influenza viruses normally circulate in animals but can also infect people. Infections in humans have primarily been acquired through direct contact with infected animals or through indirect contact with contaminated environments. Depending on the original host, influenza A viruses can be classified as avian influenza, swine influenza, or other types of animal influenza viruses.

-- Avian influenza virus infections in humans may cause diseases ranging from mild upper respiratory tract infection to more severe diseases and can be fatal. Conjunctivitis, gastrointestinal symptoms, encephalitis and encephalopathy have also been reported.

-- Laboratory tests are required to diagnose human infection with influenza. WHO periodically updates technical guidance protocols for the detection of zoonotic influenza using molecular methods. 

-- Human infections with influenza A(H9) viruses have been reported from countries in Africa and Asia, where these viruses are also detected in poultry. The majority of cases of human avian influenza A(H9N2) infection have been reported from China. This is the first imported human case of avian Influenza A(H9N2) virus infection reported in the European Region. 

Public health response

-- Contact tracing procedures have been initiated, and relevant authorities in Italy, as well as internationally (National IHR Focal Point for Senegal, WHO, and European Centre for Disease Prevention and Control (ECDC)) have been informed through IHR channels. Once avian influenza was suspected, the response moved quickly from hospital-level management to regional laboratory confirmation and national coordination. Additionally, the regional surveillance system was notified, integrated within the One Health avian influenza reporting framework.

WHO risk assessment

-- Most reported human cases of A(H9N2) virus infection have been linked to exposure to infected poultry or contaminated environments, with the majority of cases experiencing mild clinical illness. Sporadic human cases following exposure to infected birds or contaminated environments can be expected since the virus remains enzootic in poultry populations. Avian influenza A(H9N2) viruses have been detected in poultry and environmental samples collected at live bird markets in Senegal and authorities in the country reported a human case of infection with an A(H9N2) virus in 2020.

-- Current epidemiological and virological evidence indicates that none of the characterized influenza A(H9N2) viruses thus far have acquired the ability for sustained transmission among humans. Thus, the likelihood of sustained human-to-human spread is low at this time. Infected individuals traveling internationally from affected areas may be identified in another country during or after arrival. However, if this were to occur, further community-level spread is considered unlikely. The risk assessment would be revisited if and when further epidemiological and virological information becomes available.

WHO advice

-- This case does not change the current WHO recommendations on public health measures and surveillance of influenza.

-- The public should avoid contact with high-risk environments such as live animal markets/farms or surfaces that might be contaminated by poultry feces. Respiratory protection is highly recommended for those handling live or dead (including slaughtering) poultry in occupational or backyard-farming settings. Good hand hygiene, i.e. frequent washing of hands or the use of alcohol-based hand sanitizer is recommended. WHO does not recommend any specific additional measures for travelers.

-- Under Article 6 of the IHR, all human infections caused by a new subtype of influenza virus are notifiable. The case definition for notification of human influenza infection caused by a new subtype under the IHR is provided here. State Parties to the IHR are required to immediately notify WHO of any laboratory-confirmed case of a human infection caused by such an influenza A virus.

-- WHO advises against the application of any travel or trade restrictions based on the current information available on this event.

#USA, DOH and #CDC Investigate Invasive Group A Streptococcal (#IGAS) Infections in West #Hawaii (April 7 '26)

 

HONOLULU — The Hawaiʻi Department of Health (DOH) and Hawaiʻi District Health Office are working with the Centers for Disease Control and Prevention (CDC) to investigate a report of high rates of a serious bacterial infection called invasive Group A Streptococcus (iGAS) in West Hawaiʻi.

This investigation began after a local physician identified a higher-than-expected number of patients with iGAS over a period of several months and informed DOH. 

While DOH routinely monitors these infections, historically Hawaiʻi has had higher rates than the national average. 

This investigation will help determine whether the number of people with iGAS is increasing in West Hawaiʻi and better understand possible causes and risk factors of this infection.

The goals of this investigation are to confirm whether there is an increase in the number of people with iGAS in West Hawaiʻi, identify risk factors, evaluate disease reporting, and better understand how infections may be occurring in the community. 

Investigators will also compare local trends with other areas of the state and analyze laboratory data to identify any patterns among people with iGAS infections.

Group A Streptococcus bacteria are commonly found on the skin or in the throat and often do not cause an infection. 

When infections do occur, they are usually mild illnesses such as strep throat or skin infection. 

In rare cases, the bacteria can enter the bloodstream or other normally sterile parts of the body. This is called invasive Group A Streptococcus (iGAS), which can be serious. Early treatment with antibiotics is effective, especially when care is given promptly.

Some people are at higher risk for severe illness. These include older adults and individuals with chronic medical conditions such as heart, kidney, or respiratory disease and diabetes. People with weakened immune systems, those with open wounds or skin infections — and people experiencing homelessness or who inject drugs may also be at increased risk. 

In addition, recent viral infections such as influenza or chickenpox can increase one’s risk. The specific causes of the elevated iGAS illnesses in West Hawaiʻi are not yet known, so DOH and CDC are investigating.

DOH encourages the public to take simple steps to reduce the risk of infection. 

- Keep cuts and wounds clean and covered until they heal and 

- wash hands regularly with soap and water. 

- Seek medical care if a wound becomes red, swollen, warm, or produces pus. 

- Anyone experiencing fever, severe pain, or rapidly worsening symptoms should seek medical attention immediately.

DOH and CDC are working closely with healthcare providers and community partners and will continue to provide updates as more information becomes available. At this time, the overall risk to the public is low; however, awareness and early treatment are important to prevent severe iGAS illness.

#Chikungunya fever: #Brazil is intensifying its response to address health emergency in Dourados (MoH, April 4 '26)

 

{Edited}

The Brazilian government has intensified its response to the emergency situation in Dourados (MS), given the increase in cases of chikungunya, with the mobilization of an interministerial task force that integrates actions in health, assistance, civil defense, and logistical support in the territory. The emergency affects the population of the municipality, with a greater impact on indigenous communities.

As a reinforcement to the response already underway, the Federal Government has guaranteed more than R$ 3.1 million in emergency resources for the municipality. 

Of this total, R$ 1.3 million , authorized by the Ministry of Integration and Regional Development (MIDR) in a decree published this Thursday (2), will be allocated to relief and humanitarian assistance actions, such as direct support to the population and local response structures. 

Also this Thursday, the National Secretariat for Civil Protection and Defense approved a work plan worth R$ 974,100 for restoration actions, including urban cleaning, waste removal and disposal in a licensed sanitary landfill, with resources to be transferred directly to the municipality.

The Ministry of Health has already transferred R$ 855,300 to the municipality to cover the costs of surveillance, assistance, and control actions related to chikungunya in the region.

The federal response has been underway since mid-March, coordinated by the Ministry of Health, which mobilized the National Health System (SUS) Task Force , reinforced healthcare teams, and intensified vector surveillance and control actions across the territory. 

The operation includes actively searching for cases, conducting home visits, eliminating [mosquitoes] breeding sites, and expanding services to the population, with special attention to the most vulnerable areas, including indigenous territories.

The National Health System Task Force has 40 mobilized professionals , with 26 currently working directly, and has already carried out 1,288 clinical consultations , 81 transfers for medium and high complexity care, and 225 home visits . 

The teams operate both in indigenous territories and in the municipalities of Dourados and Itaporã, supporting local management, together with the Mato Grosso do Sul State Health Secretariat, reorganizing care flows, expanding active case finding, and guaranteeing assistance, health education, and psychosocial care.

Fiocruz mobilized the shipment of pain medication, reinforcing its ability to meet local demand due to the epidemic.

To expand response capacity, the Ministry of Health authorized the emergency hiring of 50 Endemic Disease Control Agents (ACEs). Of these, 20 have already been trained and will enter the field this Friday (3), while another 30 will begin training to work from Monday (6).

In the field of vector control, actions were intensified with the mobilization of approximately 95 professionals , including Community Health Agents and Indigenous Sanitation Agents (AISAN). Between March 9 and 16, 4,319 properties were inspected , of which 2,173 received treatment , identifying 1,004 breeding sites of the Aedes aegypti mosquito , mainly in water storage containers, solid waste, and tires.

Actions were also taken to control the spread of insecticide using ultra-low volume (ULV) methods, including three cycles of vehicle-mounted ULV application and backpack spraying in 43 high-traffic areas, such as schools and health units. The volunteer effort to remove breeding sites mobilized approximately 100 people and resulted in the collection of four dump truckloads of waste.

Vector control will be reinforced with support from the Ministry of Defense. Currently, 40 Brazilian Army soldiers and five vehicles are already in the area , expanding the operational capacity of the mosquito control efforts.

The Ministry of Health also sent 1,000 Larvicide Dissemination Stations (LDSs). Of the first 300 units, 150 have already been installed in priority neighborhoods, with expansion planned for other regions of the municipality.

Through Funai (National Indian Foundation), actions are also underway to provide direct support to indigenous communities in Dourados, focusing on food security and access to water. 

The distribution of 6,000 food baskets is planned , in three stages between April and June, in coordination with the Ministry of Social Development (MDS), the National Supply Company (Conab), the Special Secretariat for Indigenous Health (Sesai), and Civil Defense. The expansion of the water supply system in the Jaguapiru and Bororó villages has also been authorized to guarantee access to potable water and improve the sanitary conditions of the indigenous communities.

Epidemiological scenario

The most recent epidemiological surveillance data, referring to April 2nd, indicates that the region has registered 2,812 notifications of chikungunya, with 1,198 confirmed, 430 discarded, and 1,184 still under investigation. The highest concentration of cases is in indigenous villages, where 822 cases were confirmed—68.6% of the total confirmations in the region. 

So far, five deaths have been confirmed in Dourados, all among the indigenous population of the municipality.

To strengthen the coordination of actions, the Ministry of Health established a Situation Room in Brasília on March 25th, with permanent meetings to monitor the situation and integrate decisions between technical teams and managers.

Within the indigenous territory, the work is carried out in a coordinated manner between the Ministries of Health, Indigenous Peoples, Integration and Regional Development, Defense, Social Development, Funai (National Indian Foundation), and the Special Indigenous Health District of Mato Grosso do Sul (DSEI-MS), which has 210 Indigenous Health Agents (AIS) and 150 Indigenous Sanitation Agents (Aisan), in addition to logistical support with 91 pickup trucks, 6 vans, and 1 truck.

The actions also include training for health professionals in the municipal and indigenous networks, aligning clinical protocols for diagnosis and proper management of the disease, as well as health education activities in schools and communities. There are also plans to send prevention messages via WhatsApp to more than 234,000 residents , in Portuguese and with translation into indigenous languages.

The response also includes improving the quality of care, with the implementation of the national chikungunya protocol and training of teams for early identification of severe cases and appropriate clinical management.
