Washington State Influenza Summary

2018-2019 Season

Washington State Department of Health, Communicable Disease Epidemiology

The Department of Health (DOH), in collaboration with local health jurisdictions and the Centers Disease Control and Prevention (CDC), performed surveillance for influenza during the 2018 to 2019

season using several different systems. This report summarizes data collected through key systems from September 30, 2018 to September 28, 2019 (week 40 of 2018 through week 39 of 2019).

National Summary

Nationally, the severity of the 2018-2019 season was categorized as moderate. Nationally, influenza-

like illness (ILI) activity began increasing in November, peaked during mid-February, and returned to

below baseline in mid-April; the season lasted 21 weeks, making it the longest season in 10 years. Illness attributed to influenza A viruses predominated, with very little influenza B activity.

Washington State Summary

In Washington State, two hundred and forty five lab-confirmed influenza deaths and one hundred and

forty eight influenza-like illness outbreaks in long term care facilities were reported for the 2018-2019

season. Illness attributed to influenza A viruses predominated, with very little influenza B activity.

Influenza Laboratory Surveillance Data

Laboratory Data: World Health Organization (WHO) & National Respiratory and Enteric Virus

Surveillance System (NREVSS) Data Reported to CDC

For the 2018-2019 influenza season, CDC has generated separate graphs of data reported to CDC by public health laboratories (Figure 1) and commercial laboratories (Figure 2). Figure 1: Influenza Positive Tests Reported to CDC, WA Public Health Laboratories 2 Figure 2: Influenza Positive Tests Reported to CDC, WA Commercial Laboratories

Outpatient Influenza-like Illness Surveillance

Outpatient Influenza-like Illness Surveillance Network (ILINet) Data

Information on patient visits to health care providers for influenza-like illness is collected through the

U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet). Each week, up to 40 outpatient healthcare providers in Washington reported data to CDC on the total number of patients seen and

the number of those patients with influenza-like illness (ILI) by age group. For the purposes of ILINet,

ILI is defined as fever (temp 100ºF/37.8ºC or higher) plus cough and/or sore throat.

More information about ILINet is available here.

Long term care facilities are required to report all suspected and confirmed outbreaks to their local

health jurisdiction per Washington Administrative Code (WAC) 246-101-305. Long-term care facilities are required to report the following: A sudden increase in acute febrile respiratory illness over the normal background rate (e.g., 2 or more cases of acute respiratory illness occurring within 72 hours of each other) OR

For more information about NREVSS, see www.cdc.gov/surveillance/nrevss/index.html. Figure 5: Respiratory and Enteric Viruses, Washington, 2018-2019 Season

Laboratory Confirmed Influenza-Associated Deaths

Reported Laboratory-Confirmed Influenza Associated Deaths

Note that these counts reflect only deaths officially reported to the Washington State Department of Health and are likely

under-reported for a variety of reasons. Influenza may not be listed as a cause of death, influenza testing may not have

been performed, and lab-confirmed influenza deaths may not have been appropriately reported to public health. CDC has

published information about estimating seasonal influenza-associated deaths: www.cdc.gov/flu/about/burden/how-cdc-

estimates.htm There were two hundred and forty five laboratory-confirmed influenza deaths during the 2018-2019 season: 230 influenza A, 10 influenza B, and 5 type unknown. Most deaths occurred in people with underlying health conditions, or in people with no pre-existing conditions but who were elderly. Two deaths occurred in children.
