This new symptom could be your first omicron sign, doctors now warn

Shruti Gohil, MD, an associate medical director of epidemiology and infection prevention at UCI Health, tells Good Housekeeping that stomach issues could be an early indicator of either food poisoning or COVID-19. … “You should get tested for COVID-19 if you develop any of the 11 known COVID symptoms,” Gohil says, who adds that feeling multiple symptoms simultaneously is also a major sign. “But there are many causes of nausea and vomiting, so you should talk to your doctor to see if you need other testing as well.”
