#Mpox - Multi-country external #situation #report no. 61, published 22 December 2025 (#WHO, summary)

{Summary}

Highlights   

• All clades of monkeypox virus (MPXV) continue to circulate. 

- Unless mpox outbreaks are rapidly contained and human-to-human transmission is interrupted, there is a risk of sustained community transmission.  

• In November 2025, 48 countries across all WHO regions reported a total of 2150 new confirmed mpox cases, including five deaths (case fatality ratio [CFR] 0.2%). 

- About 68% of these cases were reported in the African Region. 

- Four regions observed a decline in confirmed cases in November, compared to October 2025, while the European and Western Pacific regions reported more cases than the previous month.     

• Nineteen countries in Africa reported active transmission of mpox in the last six weeks (2 November– 14 December 2025), with 1435 confirmed cases, including seven deaths (CFR 0.5%). 

- Countries reporting the highest number of cases in this period are the Democratic Republic of the Congo, Guinea, Liberia, Kenya and Ghana; while case reports in Liberia still show indications of a rise, weekly case counts in the other countries have been declining in recent weeks. 

• Romania has reported detection of clade Ib MPXV for the first time, in a case confirmed in August 2025.   

• Outside Africa, community transmission of clade Ib MPXV continues in Spain and in the Netherlands. 

• In the Democratic Republic of the Congo, mpox transmission continues across multiple provinces with cocirculation of clades Ia and Ib MPXV, heterogeneous subnational trends and declining access to testing of suspected cases. 

• The United Kingdom of Great Britain and Northern Ireland has reported a new travel-linked case of mpox with detection of a recombinant MPXV strain containing genetic elements of both clade Ib and clade IIb MPXV. The extent of circulation of the recombinant strain remains unknown.  

• WHO assesses the ongoing public health risk to be moderate for men who have sex with men with new or multiple partners, sex workers and others with multiple partners who may be at risk, and low for the general population with no specific risk factors, continues close monitoring of the situation, and emphases the importance of maintaining surveillance and response capacity, including genomic sequencing notably in locations where multiple MPXV strains co-circulate.

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

By G.M.
{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

By G.M.
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

By G.M.
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...
