America’s top doctor is begging people to stop panic-buying face masks — fearing a shortage could cause an even bigger medical threat.

“Seriously people- STOP BUYING MASKS!” US Surgeon General Dr. Jerome Adams complained Saturday on Twitter.

“They are NOT effective in preventing general public from catching #Coronavirus, but if healthcare providers can’t get them to care for sick patients, it puts them and our communities at risk!”

Adams insisted that “everyday preventive actions” were the “best way to protect yourself,” listing “staying home when you are sick and washing hands with soap and water” and seeking help if you are sick.

“Get your #FluShot- fewer flu patients = more resources for #COVID19,” he said of wanting to be able to prioritize the new virus that experts warn could become a pandemic.

Adams spoke out as the US had its first confirmed death from COVID-19, a man in his 50s who died in a Seattle-area hospital.

“#COVID19 is a serious disease, but for the general public the immediate health risk is considered low,” Adams insisted in a series of tweets Sunday

He also addressed potential hate crimes over the virus, which started in the Chinese city of Wuhan.

“Diseases can make anyone sick regardless of their race or ethnicity. People of Asian descent, including Chinese Americans, are not more likely to get COVID19 than any other American,” he stressed.

Dr. William Schaffner, a preventive medicine professor at the Vanderbilt University School of Medicine, told CNN that the rush to buy masks is a “psychological thing.”

“The coronavirus is coming, and we feel rather helpless,” he told the network. “By getting masks and wearing them, we move the locus of control somewhat to ourselves.”
