Health officials locally have confirmed three cases of the virus so far.
In December 2013 the mosquito-borne illness was first detected in St Martin.
Since that time most Caricom countries have reported cases of the disease.
Speaking at the weekly post executive council news briefing, Tobago House of Assembly Chief Secretary, Orville London, said although there are no cases of the virus of the island preventative efforts have been stepped up by the relevant authorities.
He also called on Tobagonians to do their part in the process.
