The public health landscape in the Pacific continues to be shaken by alarming trends in various infectious diseases as of December 17, 2024.

Dengue Fever on the Rise in French Polynesia

In French Polynesia, the dengue outbreak is escalating alarmingly. During epidemiological week 49, 53 new cases of dengue were documented across multiple islands, including Tahiti, Moorea, and Bora Bora, bringing the total confirmed cases to 453 since November 27, 2023. The incidence of dengue has been particularly notable in the Windward Islands, the Leeward Islands, and the Tuamotus, with positivity rates reaching 58%. Fortunately, while there have been four hospitalizations, no severe cases or fatalities have been reported. A maternal-fetal transmission case has emerged, adding complexity to an already concerning situation. Health officials continue to monitor the situation under a blue alert status for both DENV-1, which is becoming the predominant serotype, and DENV-2.

Pertussis Outbreak Spreads Across the Pacific

Pertussis, or whooping cough, has also emerged as a pressing concern. Recent reports indicate a total of 465 confirmed cases in French Polynesia from June to December, with 27 new cases in the latest week, predominantly from Tahiti and Raiatea. A decrease in overall cases has been noted, but the disease is still prevalent among adolescents and infants, especially those under six months. A red alert status remains in effect.

In New Caledonia, the disease is similarly troubling, with 135 pertussis cases identified since April. The latest data reveal continued infections in December, sustaining a blue alert. Meanwhile, New Zealand has reported a worrisome increase, surging to 161 cases in EpiWeek 49, with infants being the most affected demographic due to lower vaccination rates. Samoa is also contending with a substantial outbreak, reporting 109 cases, primarily in infants, and revealing alarmingly low booster vaccination rates.

Flu and Respiratory Infections Spike Globally

The surge isn't limited to pertussis and dengue fever. Flu activity and respiratory infections are surging globally, warranting urgent attention. Notably, France has recorded a sharp increase in respiratory infections, with severe bronchiolitis outbreaks reported in 12 regions. Meanwhile, in Hawaii, the first flu-associated death of a child has raised alarms as respiratory illness rates escalate amid the holiday season.

The UK Health Security Agency reports a staggering increase in flu positivity rates, now at 17.1%, combined with rising hospitalization rates. Health experts are urging eligible individuals to prioritize getting vaccinated.

Conclusion: A Call to Action

The rising tide of infectious diseases in the Pacific and beyond serves as a reminder of the vulnerabilities that public health faces today. The urgent need for vaccination, health monitoring, and community engagement is paramount in combating these threats. It's not just about statistics; it’s about protecting lives and preventing widespread outbreaks. Be vigilant, stay informed, and prioritize your health as we navigate this challenging period together.
