Long Term #Risk #Assessment: #COVID19, 5 September 2025 (#WHO, summary)



Overall global risk and confidence*

Overall risk:  Global  - Moderate   

Confidence in available information: Global - Low 


Overall risk statement

As of mid-2025, the global public health risk from COVID-19 has changed from high to moderate, with declining deaths and hospitalizations since 2022 due to high population immunity, improved clinical management, and similar virulence

Most SARSCoV-2 variants now belong to the JN.1 Omicron sublineages, which show immune escape but do not result in increased disease severity. 

Nonetheless, surveillance gaps, reduced genomic sequencing and sharing of sequence information, and limited reporting, especially from low- and middle-income countries, undermine accurate risk assessment

SARS-CoV-2 continues to circulate widely, as indicated by sentinel testing and wastewater surveillance, often co-circulating with influenza and RSV

PostCOVID-19 condition is estimated to affect around 6% of symptomatic cases, with reduced risk in vaccinated individuals

WHO encourages integration of COVID-19 monitoring into broader respiratory disease surveillance systems and recommends ongoing vaccination of high-risk populations

While available vaccines remain effective against severe disease and death even in light of variant emergence, global vaccine uptake among high-risk groups was low in 2024, raising concerns amid continued virus evolution. 

Overall, while the direct impact of COVID-19 has lessened, ongoing circulation and virus evolution – both in human populations and established animal reservoirs, low vaccine uptake, and insufficient burden and genomic surveillance data contribute to uncertainty, requiring continued vigilance. 

{*} Confidence refers to the level of confidence in the data/information or the quality of the evidence available at the time the RRA is conducted. Poor quality information may increase the overall perceived risk due to the incertitude in the assessment.

Virus origins

The Scientific Advisory Group for the Origins of Novel Pathogens (SAGO) is composed of independent scientific experts whose role is to advise WHO on technical and scientific considerations regarding emerging and reemerging pathogens, including SARS-CoV-2. 

SAGO published its independent assessment of SARS-CoV-2 origins on 27 June 2025. 

While available information is insufficient to definitively conclude the origins of SARS-CoV-2, the report includes two main hypotheses:  

-- introduction from a natural zoonotic source(s) as a spillover event(s) either directly to humans from wild animals or through an intermediate host, or 

-- an accidental laboratory-related event, which may have involved exposure to the virus during field research or a breach in laboratory biosafety procedures.  

SAGO has also developed a global framework to define and guide studies on the origins of emerging and reemerging pathogens of epidemic and pandemic potential, published in February 2025 and outlining a structured approach for investigating the origins of a novel pathogen. 


Virus evolution and variants

Omicron, the last designated variant of concern (VOC), has accounted for 97% of all submitted sequences since January 2022. Omicron has diversified considerably, giving rise to more than 2800 descendent lineages

All Omicron descendent lineages share similar phenotypic characteristics, namely higher transmissibility due to immune escape properties and lower apparent disease severity as compared to pre-Omicron variants. 

WHO continuously updates its tracking system and definitions for variants of SARS-CoV-2 to reflect the current global variant landscape. 

At present, WHO is monitoring one designated variant of interest (VOI), JN.1, and six designated variants under monitoring (VUMs): KP.3, KP.3.1.1, XEC, LP.8.1, NB.1.8.1 and XFG, all descendent lineages of JN.1. 

Between epidemiological weeks ending on 8 June 2025 and 29 June 2025  the VOI JN.1 decreased in proportion from 9.4% to 6.6%. 

During the same period, the VUM XFG increased from 23.3% to 39.1%, NB.1.8.1 increased from 28.7% to 35.5%, LP.8.1 decreased from 25.7 to 11.1, XEC decreased from 4.5% to 2.8%, KP.3 decreased from 0.7% to 0.4%, and KP.3.1.1 remained stable at 2.1%.  

Risk evaluations on the current VOI and VUMs indicate they do not pose additional public health risks as compared to other currently circulating SARS-CoV-2 lineages. 

With declining prevalence of VOIs, and VUMs increasingly unable to meet the VOI definition, WHO, on 29 November 2024, began conducting risk evaluations for VUM designations in addition to VOI designations. 

With declining prevalence of VOIs, and VUMs increasingly unable to meet the VOI definition, WHO, on 29 November 2024, began conducting risk evaluations for VUM designations in addition to VOI designations. 

Despite advances in sequencing capacity made during the pandemic, low, unrepresentative levels of genomic sequencing and sharing pose significant challenges to the assessment of the SARS-CoV-2 variant landscape. 

84% of WHO MS had capacity to sequence for SARS-CoV-2 and 94% had access to timely sequencing either internally or via international reference laboratories as of 31 December 2023. 

Between January and June 2025, a total of 88 903 sequences were shared globally by 91 countries. This marks a substantial decline compared to 462 676 sequences shared by 146 countries during the same period in 2024. While a decline in SARS-CoV-2 genomic sequencing is expected compared to the early pandemic years, the current low volume of sequences also reflects limited geographic representation—primarily from high income countries – with significant delays in sequencing and data sharing from the time of sample collection. 

Representative levels of genomic sequencing and sharing in a timely manner are essential for adequate, robust monitoring of existing SARS-CoV-2 variants and early detection and rapid assessment of emerging ones. 

WHO urges MS to maintain public reporting and publishing of genetic sequences with relevant meta-data. 

The Technical Advisory Group on Virus Evolution (TAG-VE) continues to meet as needed to assess available evidence on circulating SARS-CoV-2 variants. 

Previously specific to SARS-CoV-2, TAG-VE now has broadened its terms of reference to include other viruses, including monkeypox virus (MPXV) and Middle East respiratory syndrome coronavirus (MERS-CoV). 

Complementing the work of TAG-VE, the Technical Advisory Group on COVID19 Vaccine Composition (TAG-CO-VAC) also continues to meet regularly to assess the impact of changing variant circulation in the context of determining COVID-19 vaccine composition recommendations, as further described in below vaccine-related sections.

Mortality

As of 29 June 2025, over seven million confirmed deaths had been reported globally to WHO. 

The number of weekly reported COVID-19-related deaths has been steadily declining, now consistently below 2000 since February 2024, a level comparable to March 2020. 

This is a significant decrease compared to previous periods, such as the 10 000 average deaths reported per week during the first half of 2023 and the over 35 000 during the first half of 2022. 

Similar to case reporting, the weekly average number of countries reporting death data has declined significantly from 173 countries in the first half of 2022 to 114 and 76 in the same periods of 2023 and 2024, respectively.   

In the first half of 2025 (as of 29 June), over 16 600 deaths were reported from 42 countries, averaging 640 deaths per week across 40 countries.

#Neuroinvasive #Oropouche virus in a patient with #HIV from extra-Amazonian #Brazil

{Excerpt} A novel reassortant Oropouche virus (OROV) lineage (with medium [M], large [L], and small [S] RNA segments : M1L2S2) has driven Brazil's largest and most geographically widespread OROV epidemic , expanding beyond the endemic Amazon basin to establish local transmission across multiple Brazilian states and other previously unaffected Latin American countries . The rapid spread of this lineage underscores its evolutionary potential and reinforces its significance as a public health threat .1 Similar to chikungunya and Zika viruses, expanding arboviruses can exhibit unexpected clinical and epidemiological shifts , including vertical transmissions , neuroinvasive effects, and potentially fatal outcomes.2–4 Although OROV typically causes self-limited febrile illness, accumulating clinical and experimental evidence suggests neurotropic potential .5 This Correspondence describes the first confirmed case of neuroinvasive OROV infection caused by the emergent M1L2S2 lineage in ext...

No evidence of immune #exhaustion after repeated #SARS-CoV-2 #vaccination in vulnerable and healthy populations

Abstract Frequent SARS-CoV-2 vaccination in vulnerable populations has raised concerns that this may contribute to T cell exhaustion , which could negatively affect the quality of immune protection. Herein, we examined the impact of repeated SARS-CoV-2 vaccination on T cell phenotypic and functional exhaustion in frail older adults in long-term care (n = 23), individuals on immunosuppressive drugs (n = 10), and healthy adults (n = 43), in Canada . Spike-specific CD4+ and CD8+ T cell levels did not decline in any cohort following repeated SARS-CoV-2 vaccination, nor did the expression of exhaustion markers on spike-specific or total T cells increase. T cell production of multiple cytokines (i.e. polyfunctionality) in response to the spike protein of SARS-CoV-2 did not decline in any cohort following repeated vaccination. None of the cohorts displayed elevated levels of terminally differentiated T cells following multiple SARS-CoV-2 vaccinations. Thus, repeated SARS-CoV-2 vaccination was...

Chimeric #hemagglutinin and #M2 #mRNA #vaccine for broad #influenza subtype protection

Abstract Since multiple and unpredicted influenza viruses cause seasonal epidemics and even high-risk pandemics , developing a universal influenza vaccine is essential to provide broad protection against various influenza subtypes. Combined with the mRNA lipid nanoparticle-encapsulated (mRNA-LNP) vaccine platform and chimeric immunogen strategy , we developed a novel cocktail mRNA vaccine encoding chimeric HAs (cH5/1-BV, cH7/3) and intact M2 (termed Fluaxe), which confers broad protection against major circulating IAVs and IBVs , as well as highly pathogenic avian influenza . Two-dose intramuscular immunization of Fluaxe in mice elicited cross-reactive neutralizing antibodies , T cell responses, and long-lived immunity, resulting in robust protection against multiple lethal influenza virus infections and severe acute lung injuries . In particular, intramuscular administration stimulated systemic immunity together with a prominent lung tropism of memory cells . Moreover, Fluaxe immuniza...
