Health ministry issues flu caution, reports decline in dengue cases

Following a recent report from the Pan-American Health Organization (PAHO) concerning an increase in influenza and dengue cases in 2024 for the Region of the Americas, Jamaica’s Ministry of Health and Wellness is noting that while flu cases remain a concern, there is a decline in dengue cases locally.

“Members of the public are reminded to take precautions against influenza, also referred to as ‘the flu’ – an acute viral infection that spreads easily from person to person, mainly by coughing, sneezing and through close contact,” the health ministry said.

Flu viruses circulate worldwide and can affect anybody in any age group with varied symptoms, including fever/chills, sore throat, muscle aches, fatigue, cough, headache, and runny or stuffy nose.

Here in Jamaica, an increase in flu cases is expected, however the figures are currently not above what is expected at this time of year.

“Routine surveillance activities, including testing, continue, in order to rapidly detect any new viruses that may be introduced in the population,” said Minister of Health and Wellness Dr Christopher Tufton.

Tests are done on respiratory samples weekly and the Influenza A (H1N1) pandemic strain 2009 is the predominant strain of the flu that is in circulation in Jamaica, followed by Influenza A (H3N2) and a few cases of Influenza B.

No case of Avian Influenza A (H5N1) has been detected in Jamaica this year.

Meanwhile, the flu vaccine is available and persons – especially those in high-risk groups, such as pregnant women and the elderly – are encouraged to take it.

“Members of the public are advised to wear masks, wash hands frequently and practice good respiratory etiquette. They are also advised to avoid touching the eyes, nose or mouth, and avoid close contact with individuals who are ill or who are having flu-like symptoms,” noted Chief Medical Officer, Dr Jacquiline Bisasor-McKenzie.

STEADY DECLINE IN DENGUE

Since November 2023, there has been a steady decline in the total number of suspected, probable and confirmed dengue cases reported in Jamaica. As of September 2024, the monthly number of dengue cases has been below the epidemic threshold so the figures are not in the outbreak range.

“However, Jamaica remains on alert for dengue as the virus is endemic here. Surveillance and testing for dengue continues and prevention measures are advised,” said Minister Tufton.

Members of the public are asked to play their part in ensuring the continued decline in dengue cases by monitoring water storage containers for mosquito breeding; keeping surroundings free of debris; destroying or treating potential mosquito breeding sites; wearing protective clothing and using a DEET-containing mosquito repellant.

Influenza and dengue figures are available in the Weekly Epidemiology Bulletin that is published on the Ministry of Health and Wellness’ website: https://www.moh.gov.jm.
