Urgent Health Alerts in the Pacific: Rising Dengue and Pertussis Cases as of October 8, 2024!

The Pacific region is currently grappling with alarming health alerts as new cases of serious infectious diseases emerge. This report provides an update on dengue fever and pertussis outbreaks across French Polynesia, New Caledonia, and New Zealand.

Dengue Fever Outbreak in French Polynesia

As of October 8, French Polynesia is experiencing a surge in dengue fever cases. In Epidemiological Week 39, 11 new dengue cases were confirmed from 37 samples. This includes seven residents from Tahiti and two tourists who visited Huahine during their contagious phase. So far, a total of 165 cases have been reported since November 27, 2023, with a concerning positivity rate of 30%.

Notably, serotyping has identified DENV-2 in 52% of specimens, highlighting a potential shift in the virus's characteristics. Fortunately, no severe cases or deaths have been reported recently, but health officials are maintaining a blue alert as the situation unfolds.

Pertussis Resurgence in French Polynesia and New Caledonia

French Polynesia is also facing a significant increase in pertussis (whooping cough) cases. Between June 14 and September 29, 131 cases were confirmed, with eight new notifications in the last week. Most cases involve individuals aged 7 to 79, along with 14% being infants. As the health system remains on high alert with a red alert status, it is crucial for residents to consider vaccination and other preventative measures.

In New Caledonia, the pertussis situation is similarly concerning. Since April 2024, 63 cases have been reported, including a significant spike in September, where 36 cases were logged. Just this month, six cases have been confirmed, reinforcing the need for public awareness and vaccination campaigns.

New Zealand's Pertussis Dilemma

New Zealand is witnessing a drastic fluctuation in pertussis cases. EpiWeek 40 reports a reduction to 30 cases, down from 59 in the previous week. Despite this drop, there have been significant peaks throughout the year, especially in September with 187 cases reported.

A recent analysis indicates that the most affected demographic is individuals aged 15 to 24 years, with schools being identified as hotspots for outbreaks. Alarmingly, the resurgence of pertussis signals a return to pre-pandemic levels and highlights a critical drop in population immunity, raising concerns among health officials.

What Does This Mean for Residents?

As the Pacific grapples with these health crises, it is imperative that residents stay informed and take appropriate preventive measures. Vaccination against pertussis is key, and individuals should be wary of symptoms associated with dengue fever, such as high fever, severe headaches, and joint pain. Public health officials urge communities to take these warnings seriously and to actively participate in vaccination drives, hygiene practices, and awareness campaigns to curb the spread of these diseases.
