  10 December 2025 Situation at a glance Seasonal influenza (‘the flu’) is an acute respiratory infection caused by influenza viruses that circulate globally and year-round.  It can cause illness ranging from mild to severe , sometimes resulting in hospitalization or death.  Seasonal influenza activity has increased globally in recent months, with an increased proportion of seasonal influenza A(H3N2) viruses being detected.  This rise coincides with the onset of winter in the northern hemisphere and an increase in acute respiratory infections caused by influenza and other respiratory viruses typically observed at this time of year.  Although global activity remains within expected seasonal ranges , early increases and higher activity than typical at this time of year have been observed in some regions.  Seasonal influenza viruses, including A(H3N2) viruses, continually evolve over time.  Since August 2025, there has been a rapid increase of A(H3N2) J.2...

  {Summary} Highlights     • All clades of the monkeypox virus (MPXV) continue to circulate.  - When mpox outbreaks are not rapidly contained and human-to-human transmission is not interrupted, there is a risk of sustained community transmission .   • In October 2025, 44 countries , across all WHO regions, reported a total of 2501 new confirmed mpox cases , including 12 deaths (case fatality ratio [CFR] 0.5%).  - About 75% of these cases were reported in the African Region .  - All regions, apart from the South-East Asia Region observed a decline in confirmed cases in October, compared to September 2025.      • Twenty-one countries in Africa have reported active transmission of mpox in the last six weeks (12 October – 23 November 2025), with 1734 confirmed cases , including 10 deaths (CFR 0.6%) reported during this period.  - Countries reporting the highest number of cases in this period are the Democratic Republic of the Congo...

  Situation at a glance The purpose of this report is to raise awareness about the local transmission of clade Ib monkeypox virus (MPXV) among men who have sex with men (MSM) in countries previously unaffected or to date reporting only cases linked to travel.  This report summarizes recent epidemiological developments , response activities, and the associated global public health risk .  The second declaration of a public health emergency of international concern (PHEIC) for mpox was lifted on 5 September 2025.  As both MPXV clades I and II and their subclades continue to circulate globally, leading to substantial outbreaks in African countries , WHO continues to advise emergency preparedness and response activities .  Multiple modes of transmission underlie ongoing virus circulation , with sexual contact remaining the primary amplifier of transmission in most settings.  Since 5 September 2025, several countries across four of six WHO regions have confirmed...

  5 December 2025 Situation at a glance On 15 November 2025, WHO was notified of the 71st confirmed human case with influenza A(H5) since early 2024 in the United States of America — the first human case reported in the United States of America since February 2025 .  On 20 November, U.S. Centers for Disease Control and Prevention (CDC) laboratory sequencing verified the virus as influenza A(H5N5), representing the first globally reported human case caused by an influenza A(H5N5) virus.  The investigation by health authorities in the United States of America is ongoing.  Contact tracing identified no further cases amongst contacts, and there is currently no evidence of human-to-human transmission .  Due to the constantly evolving nature of influenza viruses , WHO continues to stress the importance of global surveillance to detect and monitor virological (including genomics), epidemiological and clinical changes associated with emerging or circulating influenza vi...

{Summary} Context   Over five years since the detection of the first COVID-19 cases , SARS-CoV-2 continues to circulate globally, causing acute illness, hospitalization, and death , alongside prolonged negative impacts on individuals, health systems , and economies , including post-COVID-19 condition (PCC or Long COVID).  While global population-level immunity has increased significantly through both infection and vaccination, the virus continues to evolve, challenging control efforts and underscoring the need for long-term, sustainable disease management .  Confirming earlier warnings from MERS-CoV and SARS-CoV-1 , SARS-CoV-2 has demonstrated the pandemic potential of coronaviruses , which remain one of the most consequential infectious disease threats of our time .  Purpose of the strategic plan   This plan sets out WHO’s strategic framework to support Member States in the sustained, integrated, evidence-based management of coronavirus disease threats , includ...

  {Summary} Situation at a glance On 1 December 2025, the Ministry of Health (MoH) of the Democratic Republic of the Congo (DRC) declared the end of the Ebola virus disease (EVD) outbreak which had been declared on 4 September 2025.  The end was declared after two consecutive incubation periods (a total of 42 days) since the last person confirmed with EVD tested negative for the virus and was discharged on 19 October 2025.  A total of 64 cases (53 confirmed, 11 probable), including 45 deaths (CFR 70.3%), were reported from six health areas in Bulape Health Zone, Kasai Province .  WHO and partners provided technical, operational and financial support to the government to contain the outbreak.  This is the country’s 16th outbreak of Ebola.  Although the outbreak has been declared over , health authorities are maintaining surveillance to rapidly identify and respond to any re-emergence.  Risk communication and community engagement activities will continue...
