Thiruvananthapuram: As many as 18 U.K returnees have so far tested positive for COVID-19, Health minister K.K Shailaja said.
Arrangements had been made to quarantine at home those who had come back from the U.K after the new variant of the virus surfaced, she told.
Eight people who returned from Britain had been found positive for the virus and their samples had been sent to the National Institute of Virology (NIV), Pune for Genomic analysis.
In the backdrop of at least six people in India testing positive for the new U.K variant SARS-CoV2 strain, the elderly and those suffering from comorbidity symptoms should be vigilant, the minister said.
She said surveillance at the four international airports in Kerala has already been strengthened.
