The Karnataka government has issued a directive for individuals aged 60 and above, with comorbidities, and experiencing symptoms such as cough, phlegm, and fever, to wear face masks. This precautionary measure comes in response to the detection of a case of the COVID-19 sub-variant JN.1 in neighboring Kerala. Health Minister Dinesh Gundu Rao emphasized the importance of increased testing for those displaying symptoms and suspected cases, along with heightened surveillance in border districts like Kodagu, Dakshina Kannada, and Chamarajanagara that share borders with Kerala, as reported by PTI.
