INFORMATION CONCERNING AVIAN INFLUENZA A (H7N9) VIRUS: UPDATE #5
DATE: MAY 3, 2013
[NEW ITEMS IN BLUE]
Information concerning reports of the Avian Influenza A (H7N9) virus is being provided to Safety Professionals and Emergency Managers for the purpose of:
- Awareness of the emergent status of the H7N9 novel flu;
- Identification of current and recommended U.S. preparedness activities for this bio hazard; and
- Identification of a Point of Contact for further questions related to information provided.
BACKGROUND:
Through May 3, 2013, the Chinese government and Chinese Centers for Disease Control continue their investigation of the Avian Influenza A (H7N9) virus, occurring in nine (9) provinces and Taiwan. An initial informational update was processed, and updates are now produced routinely for use. A U.S. Centers for Disease Control and Prevention issued Health Advisory was disseminated with the initial updates, and has not been amended or withdrawn as of this date.[1] It can be viewed online at www.bt.cdc.gov/HAN/han00344.asp.
Additional information for May 3, 2013 relative to this event is found below:
- On April 19, 2013, the Secretary of the U.S. Department of Health and Human Services (HHS) issued a determination of significant potential for public health emergency, and an Emergency Use Authorization (EUA) for in vitro diagnostic detection for the H7N9 novel virus.
- On April 22, 2013, the U.S. Food and Drug Administration (FDA) issued an EUA for the use of real time PCR Panel – Influenza A1H7 assays. These H7N9 presumptive diagnostic kits are now available for ordering from public health laboratories.
- HHS/BARDA continues to support the advanced development of four (4) novel anti-viral drugs for treatment of influenza.
- As of May 3, 2013, there are 128 human cases in China, 27 fatalities (21.1% fatality rate), with one case reported in Taiwan. The World Health Organization (WHO) reports cases as being identified across a growing number of countries (although CDC has not confirmed), and it is likely that this will continue, however, the WHO Risk Assessment has not changed. There are four (4) identified clusters of human to human transmission, however there is currently no evidence of sustained human to human transmission; the strain has been identified in numerous live bird markets.
- There have been 40 individuals identified within the United States from 19 states, with ILI and recent travel to China. 39 cases have been tested and are negative with one (1) test results pending.
- It is safe to eat meat from healthy animals, including poultry and game birds, provided they are properly cooked and handled during food preparation. Influenza viruses are not transmitted through well cooked food.
- U.S. HHS continues to partner with antiviral manufacturers to assess the antiviral chain, including available doses in the commercial supply chain. Investigation lots of vaccine are anticipated to be available for testing in late June by NIH/manufacturers.
- HHS/BARDA continues to communicate with ventilator, surgical mask, and N-95 respirator manufacturers to understand inventory. Stockpiled quantities are known.
- Case definitions and recommended protective actions and personal protective equipment recommendations have not changed from update #1. These were described in the Health Advisory, distributed by CDC on April 5, 2013.1
- FDA is continuing to investigate devices, including online sales of devices with claims to prevent flu infections including ultra violet devices.
