The country has seen a nationwide surge in cases of RSV, including here in Idaho.
Babies and children are especially vulnerable to the respiratory virus.
Data from the Idaho Department of Health and Welfare (IDHW) shows RSV positivity, and positive cases, have surged in the last three weeks. For MMWR week 46 - which was measured Nov. 20, Idaho had 371 positive RSV tests with a 22.6% positivity rate.
"In previous years, we've seen the percent positivity of RSV tests kind of peak no higher than about 35%, and then they come back down. We're at just a little over 22% positivity right now. I think we can anticipate being somewhere between 30-33% by the time we get in all the test results for this week," Dr. Kathryn Turner, deputy state epidemiologist for Idaho Department of Health and Welfare's Division of Public Health said.
