OVERSEAS EMERGING RESPIRATORY VIRUS INTELLIGENCE

There is no evidence of sustained human-to-human transmission.[1, 3] The US Centers for Disease Control and Prevention (CDC) are investigating a cluster of illness associated with a confirmed case of influenza A(H5N1) reported in Missouri on 6 September 2024.[4] The case was identified through the seasonal influenza surveillance system and has recovered following hospitalisation associated with un. [...] The current overall individual and population health risk to the general public from this virus remains low, and the future pandemic risk is assessed as moderate, which is similar to previous assessments of earlier influenza A(H5N1) viruses.[15] On 14 August 2024, the joint FAO/WHO/WOAH assessment on the recent influenza A(H5N1) virus situation in animals and people was updated.[1] The global publ. [...] Clade 2.3.2.1.c On 2 September 2024, the WHO published a risk assessment for avian influenza A(H5N1) in Cambodia following the notification of a confirmed case due to clade 2.3.2.1c in a 15 year old child.[16] Cambodia has reported 10 human cases of infection due to influenza A(H5N1) in 2024, most of whom had known exposure to dead or sick poultry prior to illness onset. [...] This clade has previously been detected among birds in India.[17] ESR public health risk assessment Given the potentially high impact of the disease, very low likelihood of sustained human-to human transmission and very low likelihood of importation of a human case of influenza A(H5N1), the overall public health risk of avian influenza A(H5N1) to Aotearoa New Zealand is low. [...] Based on currently available information, WHO assesses the current risk to the general population posed by this virus as low.[20] From 8 June to 19 July 2024, two human cases of infection with influenza A(H5N6) in China, one human case of infection with influenza A(H9N2) in China, and two human cases of infection with influenza A(H1N2) variant virus in the US were reported.
