This newest coronavirus, COVID-19, has been making headlines nonstop ever since it arrived in the United States. The virus has infected 110,000 people worldwide and killed around 3,900 — even though in the U.S., those numbers are much smaller, according to The Associated Press. There’s a lot to know about how to protect yourself from the coronavirus, but one of the most important things to know is how it spreads. The first infections were linked to a live animal market, but it’s now spreading from person to person, health officials said. The CDC recommends keeping infected and possibly infected people quarantined so that the virus can’t spread anymore.
