Tonga is on alert this week as the Ministry of Health confirmed three cases of dengue fever in Tongatapu, a 15-year-old male from Houmakelikao, a 35-year-old male from Fo'ui, and a 12-year-old female from Haveluloto, with no evidence of epidemiological linkage. More dengue fever cases are expected during the wet season.
The Ministry of Health (MOH) stated that diagnoses were made through positive blood tests (PCR) after developing fever and other symptoms.
The first case was admitted to Vaiola Hospital last week and has already been discharged, while the last two cases are currently on home treatment and management, both are in stable condition.
"In the context of dengue epidemiology, particularly during this wet season with the widespread presence of Aedes mosquito vectors that responsible for the transmission of the dengue virus, more cases are expected as such unlinked cases represent a high risk for rapid amplification of transmission if not addressed promptly," MOH noted.
Health Officers in charge of all health facilities across the country have been alerted and encouraged to have high index of suspicion for early detection and treatment of cases.
Meanwhile, the Public Health response teams have been mobilized to conduct active case investigation, contact tracing, robust vector control, risk communication and community engagement, and other preventative measures.
The Ministry reminds the public that dengue fever is contagious. It spreads from person to person through the bites of infected mosquitoes. The public is also urged not to panic but to learn about dengue fever and present early to the nearest health facility if they develop symptoms.
Dengue Fever symptoms include:
- Sudden high fever
- Severe headaches
- Pain behind the eyes
- Joint and muscle pain
- Nausea
- Vomiting
- Swollen glands
- Rash that appears 3-4 days after fever begins
Severe symptoms, such as abdominal pain, bleeding gums, vomiting blood or any other forms of bleeding require immediate medical attention.
