CARPHA urges greater protection against mosquito-borne diseases during COVID-19 pandemic

May 06, 2021

PORT OF SPAIN, Trinidad, CMC – The Caribbean Public Health Agency (CARPHA) has urged residents of the region not to neglect to protect themselves against mosquito-borne diseases, even as they battle the COVID-19 pandemic.

During the last quarter of 2020, several CARPHA member states reported localised outbreaks of dengue, which placed an even greater burden on national health systems already engaged in managing the pandemic.

“Moving forward to 2021, we must all play our part in the prevention and control of mosquito-borne diseases in order to maintain our health and well-being, especially during the COVID-19 pandemic,” said CARPHA Executive Director, Dr Joy St John, in observance of Caribbean Mosquito Awareness Week 2021.

“The Aedes aegypti mosquito is a major vector, which spreads diseases such as dengue, Chikungunya, and Zika. These diseases can be a significant cause of illness and even death, impacting countries negatively on an economic and social level,” added Dr Laura-Lee Boodram, head of vector-borne diseases at CARPHA.

“The introduction of Chikungunya and Zika in 2014 and 2016, respectively, into the Caribbean region, together with the presence of competent vectors such as Aedes aegypti, means that constant vigilance must be maintained.”

The Trinidad-based CARPHA noted that the potential for outbreaks to occur and the introduction of new mosquito-borne diseases in the region are ever-present threats, and it is working in conjunction with member states and various international development partners on strategies to prevent and control mosquito-borne diseases in the region.

CARPHA pointed out that as the rainy season approaches, water can accumulate in the base of plants pots, vases, buckets, and used vehicle tyres, which are typical breeding sites, and an increase in vector populations will further the risk of disease transmission.

“The best way to 'fight the bite' around homes and communities is to ensure that our surroundings are clean and free of materials or containers that can accumulate water. Water storage drums and tanks should also be properly covered and inspected periodically to ensure that there is no breeding,” advised Rajesh Ragoo, senior technical officer, vector-borne diseases at CARPHA.

“It is also important to minimise individual exposure to mosquito bites. Vulnerable groups such as infants, young children, older adults, and women who are pregnant or trying to get pregnant are at greater risk. Personal protective measures including the wearing of long-sleeved clothing and the use of insect repellents are strongly recommended.”

CARPHA has recommended that greater efforts be placed on mosquito awareness in communities and that vector control activities should be intensified.
