PAHO Provides Guidance To Countries In Response To Increased Chikungunya Cases

(CMC) – The Pan American Health Organization (PAHO) is calling on countries of the Americas, including those in the Caribbean, to strengthen measures to diagnose and manage chikungunya due to an increase in cases in some areas.

It said that the warning should be taken seriously because of the higher numbers of susceptible persons and the start of the peak transmission season.

Chikungunya fever is transmitted by the Aedes mosquito, which is also responsible for spreading dengue and Zika. It can cause high fever, joint and muscle pain, and headache.

There is no approved vaccine or specific treatment for the disease. On rare occasions, it can cause severe symptoms and lead to death, mainly in pregnant women, children under the age of one, older adults and people with comorbidities.

According to the PAHO epidemiological alert, in 2021, there were over 137,000 reported cases and 12 deaths due to the disease. But in 2022, cases almost doubled, and 95 deaths were reported in 13 countries across the region.

It said in the first four weeks of this year, 30,707 cases of chikungunya were reported as well as 14 deaths.

PAHO has urged member states to continue strengthening surveillance, triage, diagnosis and the timely and appropriate treatment of chikungunya and other mosquito-borne disease cases.

In the alert, PAHO also called on countries to step up health service capacity and preparedness, including drawing up plans for screening and reorganising services in case of outbreaks and strengthening care networks.

The surveillance guidelines include recommendations on appropriate sampling and laboratory algorithms for diagnostic confirmation by molecular testing, considering differential diagnosis with other pathologies.

PAHO also recommend that specific care be provided to patients at different levels of care and stages of infection, which may require training of health personnel in diagnosis and case management.

“The best protection against chikungunya is to avoid mosquito bites. The main method of reducing transmission is to mobilise communities to reduce and eliminate mosquito breeding sites. If chikungunya infection is suspected, it is recommended that persons seek immediate assistance at a health clinic,” PAHO added.
