1. H5N1 Avian Influenza

• Human Cases (2003 - Jan 16, 2013): 610 lab-confirmed cases globally, 360 deaths.
• Recent Findings: Indonesia reported poultry outbreaks linked to H5N1 clade 2.3.2.1 (first detection there), causing concern as it circulates elsewhere; however, risk unchanged per WHO.
• Public Health Risk: Remains unchanged.

2. Influenza A(H3N2)v Variant

• No New US Cases: As of report time, no new H3N2v human cases reported from USA.
• Potential Risk: Further human cases or clusters expected due to ongoing circulation in US swine.
• Monitoring: Close monitoring required.

3. Animal Outbreaks and Public Health Impact

• Increased Reports: More animal influenza outbreaks recently, timing consistent with northern hemisphere winter.
• Mexico Update: H7N3 poultry outbreaks in Mexico. Previously, mild human cases (conjunctivitis) linked to H7N3 occurred in Mexico during summer 2012.
• Public Health Message: Need for awareness and safety measures during animal influenza outbreaks, especially for those working/living near affected animals. Collaboration with animal health partners emphasized.

Overall Assessment: WHO underscores the need for global influenza monitoring and IHR(2005) reporting per member state.
