The scientists obtained data from the COVID Symptom Study app to evaluate whether they could use the presence of skin rashes to help diagnosis Covid-19 infections. Also, they performed an independent online survey of nearly 12,000 respondents to gather information on skin-related symptoms of Covid-19.

Here’s what you need to know:

• Skin rashes were significantly associated with the chances of a positive Covid-19 test result, with an increase in the probability of just under 1.7-times.
• Body rashes appeared more frequently than did rashes on the fingers and toes, but the rashes in the differing locations had comparable predictive value.
• For those with a Covid-19 infection, 17 percent had a rash as the first symptom, while 21 percent reported rashes as the only symptom.

If you are like me, you probably want to see pictures. I will not disappoint you as a catalog of 400 images is publicly available at covidskinsigns.com.

Skin rashes can be a point to a Covid-19 infection. Increased awareness for the general public and healthcare providers should aid in more efficient detection of disease
