OVERSEAS EMERGING RESPIRATORY VIRUS INTELLIGENCE

OVERSEAS EMERGING RESPIRATORY VIRUS INTELLIGENCE Highly Pathogenic Avian Influenza A(H5NX) On 6 September 2024, the US Centers for Disease control and Prevention (CDC) reported a human case of avian influenza A(H5) in Missouri.[1] The case was identified through the seasonal influenza surveillance system and has recovered following hospitalisation. [...] H5 avian influenza outbreaks have been detected in poultry in Missouri in 2024 and in wild birds there in the past. [...] 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.[13] 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. [...] This clade has previously been detected among birds in India.[15] 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.[16] In August 2024, the CDC reported four human cases of infection with swine influenza in the US: two cases of A(H3N2) variant virus, one case of influenza A(H1N1) variant virus and one case of influenza A(H1N2) variant virus.
