OLYMPIAWashington State Department of Health(DOH)has published a new, weekly report thatprovides an insight intoCOVID-19reinfections. This report includes information on hospitalizations and deaths, demographics, trends over time, and vaccination status of people with a reinfection where DOH has information about both infection events.

Reinfection means a person was infected once with the virus that causes COVID-19, recovered, and then later became infected again.A person with a reinfection could be fully vaccinated, partially vaccinated, or unvaccinated. This report is located on theCOVID-19 Data Dashboard :: Washington State Department of Healthand isupdated weekly.

We are still learning about COVID-19 and the duration and strength of immunity following infection with this virus,said Scott Lindquist, MD, MPH, state epidemiologist for communicable diseases.Based on what we know from similar respiratory viruses, we expect some COVID-19 reinfections to occur.

The first report indicates that from September 1 through December 26, 2021, in Washington state:

DOHcan only identify people who have been reinfected if both their original infection and their second infection were diagnosed by a COVID-19 test and reported tothe state. Since many COVID-19 infections are asymptomatic and not diagnosed by a test, DOH will not be able to classify those individuals as reinfected. As a result, thereportednumber of people reinfected or hospitalized or died from a reinfection is likely lower than the actual number of reinfection events.

The risk of reinfection is likely dependent on a variety of factors including:

This risk may change over time as immunity wanes or as new variants emerge.Variants associated with reinfections will be includedin theSARS-CoV-2 Sequencing and Variants in Washington State. Ongoing COVID-19 studies will help us understand more about cases of reinfection.

While reinfection is relatively rare,the best protection againstgetting any COVID-19 infectionis to get vaccinated, and then get a booster shot when eligible. Children between the ages of 5 and 11 are now eligible for the COVID-19 vaccine and should start their two-shot series immediately.As of today, youth ages 12 to 17 may receive a booster dose of the Pfizer-BioNTech COVID-19 vaccine at least 5 months after completing their primary vaccination series.
