Eight people who recently returned from the UK to Kerala, have tested positive for coronavirus and their samples have been sent to the National Institute of Virology, Pune for genomic analysis, Health Minister KK Shailaja said on Saturday.
Following this development, it has been decided to subject the returnees to more tests, she added. Surveillance at the four international airports in the state have been further strengthened.
After the recently held local body polls, it was feared that there would be a massive surge in cases.
However, that did not occur.
