Novel Influenza A (H7N9) Health Alert

Posted on May 1, 2013 in Infection Prevention | 0 comments

The World Health Organization Report on Cases of Novel Influenza A (H7N9) in China reports there has been 51 laboratory confirmed cases, 11 deaths and no person-to-person transmission or epidemiological link of any cases to date.

Consider the possibility of novel influenza A (H7N9), if a patient is ill and has had: 1) recent travel to countries with human cases, especially those with close/direct contact with animals and/or 2) recent contact with a known human case of infection with novel influenza A (H7N9).

In the RARE event that we have a possible case of novel influenza A (H7N9), please do the following:

  • Implement Standard plus Droplet, Contact, and Airborne precautions including eye protection, negative pressure or AIIR
  • Collect nasopharyngeal specimen and send to CCPH Lab
  • Order novel influenza A (H7N9) PCR test and send to CCPH lab
  • Antiviral treatment with neuraminidase inhibitors should be started as soon as possible after the onset of illness (preliminary data suggest that the virus is susceptible).
  • Cases of influenza due to novel viruses are reportable on California.
