Chikungunya virus infects 12 more in Guyana

Guyana is reporting at least 12 more cases of a mosquito-borne virus that causes severe joint pain and fever for many of its victims.

Health Minister Bheri Ramsarran says the Caribbean Public Health Agency confirmed the new cases of chikungunya among 130 blood samples sent from the South American country.

The minister said late Wednesday that the infections occurred near the border with Suriname and about 32 kilometres from where the first two cases were documented last week.

The government is spraying pesticides to control the two species of mosquitoes that spread the virus.

The Pan American Health Organization reports more than 100,000 cases of chikungunya since the first locally transmitted case on the generally non-fatal virus in the Caribbean in French St. Martin in December.

On Thursday, the U.S. Centers for Disease Control and Prevention suggested local public health departments perform surveillance for chikungunya cases in returning travellers and be aware of the risk for possible local transmission in areas where Aedes species mosquitoes are active.

“Local transmission has been identified in 17 countries or territories in the Caribbean or South America (Anguilla, Antigua and Barbuda, British Virgin Islands, Dominica, Dominican Republic, French Guiana, Guadeloupe, Guyana, Haiti, Martinique, Puerto Rico, Saint Barthelemy, Saint Kitts and Nevis, Saint Lucia, Saint Martin, Saint Vincent and the Grenadines, and Saint Maarten),” the CDC’s weekly report on illness and death said.

“As of May 30, 2014, a total of 103,018 suspected and 4,406 laboratory-confirmed chikungunya cases had been reported from these areas.”

chikungunya virus infects people on 5 Caribbean islands

Chikungunya, a viral disease spread by mosquitoes, has been confirmed in people on several Caribbean islands, the Public Health Agency of Canada says in a travel health notice.

“There have been confirmed cases of chikungunya on the Caribbean islands of Saint Martin/Sint Maarten, Guadeloupe, Martinique, Saint-Barthélemy and the British Virgin Islands,” the agency says. “These cases in the Caribbean mark the first time that locally acquired transmission of chikungunya has been detected in the Region of the Americas.”

The U.S. Centers for Disease Control and Prevention said local transmission means mosquitoes in the area have been infected and are spreading it to people.

The chikungunya virus can cause fever along with an arthritis-like pain in the joints and a rash. It is spread to humans through the bite of an infected mosquito. Although caused by a different virus, the symptoms of chikungunya can appear very similar to those of dengue fever.

Dominica and French Guiana have each reported a case of chikungunya related to travel from within the Caribbean, the Canadian agency said.

The disease is typically found in Africa, Asia and the Indian subcontinent, according to the World Health Organization. In recent decades mosquito vectors of chikungunya have spread to Europe and the Americas.

Federal public health officials advise travellers to take precautions, such as protecting yourself from mosquito bites, particularly during peak mosquito biting times in the early morning and late afternoon.

The Public Health Agency also recommends that people consult a health care provider or visit a travel health clinic at least six weeks before you travel.

It says if you develop flu-like symptoms when you are travelling or within 12 days after you return, see a health care provider and tell them where you have been travelling or living.
