-As of April 5th, 14 confirmed cases of a new influenza A virus (H7N9) have occurred in China. Six of those have died.
-Presumed transmission via infected poultry in bird markets, and thus far no person-to-person transmission has occurred.
-Likely susceptible to oseltamavir or inhaled zanamivir
Area of the world affected:
-China
Relevance to the US physician:
- Suspect in patients with a respiratory illness and appropriate travel history.
- Refer to CDC within 24 hours if test positive for flu A but cannot be subtyped
- If H7N9 is suspected, patients should be under droplet and airborne precautions
Bottom Line:
No human-to-human transmission from H7N9 thus far, but the possibility exists. Any unsubtypeable influenza A patient should be placed on droplet and airborne precautions and oseltamavir or zanamivir started immediately.
