A new, more contagious COVID-19 variant, Nimbus (NB.1.8.1), is spreading this summer. According to Erin Carlson, a clinical professor and infectious disease expert, the variant’s increased ability to bind to cell receptors makes it more contagious than recent variants.
Infected individuals are experiencing a painful sore throat, nicknamed “razor blade throat,” as well as gastrointestinal symptoms like nausea, bloating, and diarrhea. While the variant is not more deadly, those with weakened immune systems or underlying health conditions face a higher risk of getting seriously ill.
To protect yourself, stay current with vaccinations, wear masks when necessary, and maintain good hygiene habits. Carlson emphasizes that staying up-to-date on your COVID-19 vaccine is crucial, especially during high-risk periods in the summer.
