The total number of cases for 2024 was 15.Of the cases reported so far in 2025, at least 13 recently travelled to affected areas overseas while at least three local cases are not linked to one another, said CDA in response to queries from The Straits Times.There were initially two cases in February, gradually increasing at about two cases a month until there were nine by the end of May. However, the number jumped to 13 in June and then to 16 in July.CDA said if new information surfaces that suggests the virus poses an increased risk in Singapore, it will review the need for additional public health measures.
