Utah has confirmed 300 measles cases in an ongoing outbreak, with the virus now spreading in Salt Lake County and new exposures at high schools in that county, according to an update yesterday from the Salt Lake County Health Department (SLCoHD). “The first measles symptoms are often cold- or flu-like, with cough, runny nose, red/watery eyes, and fever, so you may think you have a common respiratory illness and can continue engaging in normal activities,” said Dorothy Adams, executive director of SLCoHD. “But please stay home if you have any signs of illness, especially now that we know measles is actively circulating in our community.” (Soucheray, 2/19)

New outbreaks of measles, which had been considered eradicated in the U.S., may force colleges to rethink their vaccine strategies. There is no standard way universities approach vaccine reporting, requirements or exemptions, with some given a far freer hand by their home states than others. But in the face of rising vaccine skepticism, the University of Wisconsin-Madison announced last week it is shifting to require students to disclose their vaccination status, and it is possible that other schools may follow suit.

The saliva circulating in your mouth contains troves of microbial information about the rest of your body and is easier to collect than blood samples. Today, a few drops of spit can help detect viruses like HIV and the one that causes COVID-19, or assess genetic risks for breast cancer. Within a few years, experts say, similar tests might be available to diagnose other diseases, such as diabetes or prostate cancer. (Noguchi, 2/20)
