  {Summary} Situation at a glance The global cholera situation continues to deteriorate , driven by conflict and poverty, posing a significant public health challenge across multiple WHO regions.  Between 1 January and 17 August 2025, a total of 409 222 cholera/Acute Watery Diarrhoea (AWD) cases and 4738 deaths were reported globally, from 31 countries , with six of the 31 countries reporting case fatality rates above 1%, indicating serious gaps in case management and delayed access to care.  Cholera is resurging in a number of countries , including some that had not reported substantial case numbers in years, like Chad and the Republic of Congo , while other countries, such as the Democratic Republic of the Congo , South Sudan , and Sudan , are experiencing outbreaks that are continuing from 2024, with significant geographic expansion. This complicates containment efforts and strains fragile health systems.  Conflict, mass displacement, disasters from natural hazard...

{Excerpts} The Forty-second meeting of the Emergency Committee under the International Health Regulations (2005) (IHR) on the international spread of poliovirus was convened by the WHO Director-General on 18 June 2025 with committee members and advisers meeting via video conference with affected countries, supported by the WHO Secretariat.   The Emergency Committee reviewed the data on wild poliovirus ( WPV1 ) and circulating vaccine derived polioviruses ( cVDPV ) in the context of the global target of interruption and certification of WPV1 eradication by 2027 and interruption and certification of cVDPV2 elimination by 2029.  Technical updates were received about the situation in the following countries: Afghanistan, Angola, Burkina Faso, Guinea, Nigeria, Pakistan , and Papua New Guinea . (...) Conclusion The Committee unanimously agreed that the risk of international spread of poliovirus continues to constitute a Public Health Emergency of International Concern (PHEIC) a...

  New human cases {2}:  -- From 28 May to 1 July 2025 , based on reporting date, the detection of influenza A( H5N1 ) in nine humans , influenza A( H9N2 ) in three humans and influenza A( H10N3 ) in one human were reported officially. Additionally, one human case of infection with an influenza A(H5N1) virus was detected.  Circulation of influenza viruses with zoonotic potential in animals :  -- High pathogenicity avian influenza (HPAI) events in poultry and non-poultry continue to be reported to the World Organisation for Animal Health (WOAH).{3} The Food and Agriculture Organization of the United Nations (FAO) also provides a global update on avian influenza viruses with pandemic potential.{4}  Risk assessment {5}:  -- Sustained human to human transmission has not been reported from these events.  -- Based on information available at the time of the risk assessment, the overall public health risk from currently known influenza viruses circulating at t...

{Excerpt} 1. Background   A risk assessment exercise using the Tool for Influenza Pandemic Risk Assessment ( TIPRA ) was conducted for Clade 2.3.4.4b A(H5N1) genotype B3.13 virus in Aug – Oct 2024 .   From late 2023, unexplained illnesses were reported in dairy cattle across multiple states in the United States .  Following those events , detection of avian influenza A(H5N1) in dairy cattle from Texas was confirmed on 25 March 2024.  As of 9 December 2024 , the virus has been detected in 720 dairy cattle herds across 15 states, according to the United States Department of Agriculture (USDA), with a total of 47 human infections from poultry and dairy cattle sources, excluding 11 human cases from Washington state , that might belong to genotype D1.1, also reported.  Wild and domestic animals (e.g., cats, raccoons) near infected herds have been affected as well.  The outbreak remains uncontrolled .  Due to the unprecedented spread of the virus among ...

When mpox outbreaks are not rapidly contained and human-to-human transmission is not interrupted , they continue to pose a risk of sustained community transmission .   • Since the last edition of this report, no new countries have reported cases of clade Ib MPXV for the first time.   • Nineteen countries in Africa have reported ongoing mpox transmission in the past six weeks. Clade IIb MPXV continues to be reported in West Africa , while Central African countries report both clade Ia and clade Ib MPXV, and East African countries report clade Ib MPXV .  • The recent overall downward trend of confirmed cases across the continent is driven by the decrease in cases in Sierra Leone , the Democratic Republic of the Congo , and some reporting delays. Challenges with access to testing continue in the Democratic Republic of the Congo.   • An upward trend has bee...

  Situation at a glance Since mid-February 2025, according to data available from sentinel sites, global SARS-CoV-2 activity has been increasing, with the test positivity rate reaching 11%, levels that have not been observed since July 2024.  This rise is primarily observed in countries in the Eastern Mediterranean, South-East Asia, and Western Pacific regions .  Since early 2025 , global SARS-CoV-2 variant trends have slightly shifted. Circulation of LP.8.1 has been declining, and reporting of NB.1.8.1, a Variant Under Monitoring (VUM), is increasing , reaching 10.7% of global sequences reported as of mid-May.  Recent increases in SARS-CoV-2 activity are broadly consistent with levels observed during the same period last year, however, there still lacks a clear seasonality in SARS-CoV-2 circulation, and surveillance is limited.  Continued monitoring is essential . WHO advises all Member States to continue applying a risk-based, integrated approach to managing C...
