If you go on TikTok or Instagram, you’ll see legions of wellness influencers promoting the benefits of unpasteurized “raw” milk, which hasn’t been heated to kill off illness-causing microorganisms.

Rats in New York City are becoming more than a nuisance.

A new study published by researchers from the Centers for Disease Control (CDC) this week has found that using tap water to perform a nasal rinse increases the risk of contracting a rare but serious set of infections. In particular, the CDC reports that a type of amoeba known as acanthamoeba, can cause a range of symptoms and has a fatality rate of 82%. This infection is rare and is thought to only involve 3-12 people in the US each year.

It really is a time for fun and relaxation. And, unfortunately, it’s also a time for something we don’t want to think about after three years of COVID-19: disease. But the reality is, Nevada does seem to be something of a hotbed for communicable disease and infections.

The virus is most prevalent in semi-tropical and tropical areas, such as Central and South America, Southeast Asia, and Africa. Tropical diseases could spread more widely in the U.S. as the climate changes.
