Zika Cases on the Decline; CARPHA urges fight against mosquitoes to continue

Executive Director of the Caribbean Public Health Agency (CARPHA), Dr C. James Hospedales has called for continued vigilance even though the number of cases of Zika has significantly declined from the outbreak of 2016.

This is according to statistics were revealed as part of an information package disseminated to Member States in observation of Caribbean Public Health day 2017.

The package profiles Zika since its arrival in the CARPHA Member States and addresses the epidemic and its impact on health, the economy and the tourism sector.  It also highlights actions of member states and partners, new technologies and approaches, and what CARPHA is doing to help its member states.

This newest mosquito-borne disease to the Region came on the heels of chikungunya which affected the health and economic structure of most countries and territories.

CARPHA noted that in late 2015, the Caribbean confirmed its first case of the Zika virus, followed by a dramatic increase in 2016.  The number of laboratory requests and confirmed tests peaked in August, then began a steady decline to December.  The Zika epidemic has shown signs of a significant slow-down, and the risk to residents and visitors is deemed much lower. However, the region continues to struggle and fight against the Aedes aegypti mosquito responsible for its transmission.

Zika has been associated with an increase in Guillian Barre syndromes (GBS) in five CARPHA member states (CMS).  A Zika-associated case of microcephaly has also been reported in one country. No reports of sexually transmitted Zika cases in CMS have been documented. These associated complications can have a marked impact on the people affected and their communities.

Dr Hospedales said “The Region has seen dengue, Chikungunya, and now Zika which is transmitted by the same mosquito, and the key to tackling them is prevention and control.  We must continue to literally wage war on them. But we need to be smarter. We need new approaches and technologies and partners against this threat, which is present throughout most of the tropical world.”

CARPHA revealed that its reference laboratory received thousands of requests for testing, and as of April 2017, 24 Members States reported locally transmitted cases of the virus.
