The state has so far reported four COVID-19 fatalities, including a four-month-old baby girl.
Kerala has been witnessing a steady increase in coronavirus cases with non-resident Keralites, stranded abroad and other states, returning to the state.
Chief Minister Pinarayi Vijayan has said elaborate arrangements for testing those coming to the state by road, rail, flights and ships would be made.
"We are entering a new phase of COVID-19 prevention as 'Pravasi' (expatriates) Malayalees are returning. It will be a big challenge to keep those coming from hotspots safe," Vijayan said on Tuesday.
For several days in recent weeks, the state had reported either nil fresh cases or in single digits.
