The Ministry of Health reports that the country has seen a sustained decline in autochthonous malaria cases, with a total of 11 local cases to date, representing a 94.5% reduction compared to the same period in 2024.

Rabies remains a major public health concern in Vietnam, with 89 human deaths in 2024—nearly half among children—and 58 cases reported by mid-September 2025. Low dog vaccination rates, the dog and cat meat trade, and weak surveillance contribute to its persistence. Rising animal cases and limited active monitoring suggest underreporting.

Wild poliovirus type 1 (WPV1) has been detected in a wastewater sample in Hamburg. This marks the first detection of wild poliovirus since routine environmental sampling began in 2021 and the first detection in Europe since 2007, when it was found in Switzerland, as well as in Russia and Tajikistan in 2010.

No human cases of poliomyelitis have been reported in Germany; the last indigenous case occurred over 30 years ago, in 1990. The last two imported cases were detected in 1992 from travelers with a history of travel to and from India and Egypt. Since late 2024, circulating vaccine-derived poliovirus type 2 (cVDPV2) has also been detected in wastewater samples from multiple locations in Germany.

The genome sequence of the isolate from the wastewater in Hamburg shows a very strong similarity to a genetic cluster in Afghanistan, as analyses in collaboration with the World Health Organisation (WHO) have shown. The wastewater sample was taken on 6 October 2025 (calendar week 41/2025) and analysed as part of the research project to detect polioviruses in wastewater (PIA).

Globally, WPV1 remains endemic only in Afghanistan and Pakistan. 

The Swiss Federal Department of Foreign Affairs (FDFA) and the German Federal Foreign Office advice against non-essential travel to Tanzania.

Following the presidential and parliamentary elections on 28–29 October 2025, several cities have experienced protests and violent clashes, notably in Dar es Salaam and Arusha. These incidents have resulted in fatalities, property damage, and authorities may impose curfews. 

In Macapá (state Amapá) and Ibititá (state Bahia) several cases of foodborne Chagas infection have been confirmed.

Chagas is endemic in Brazil. Foodborne transmission with periodic outbreaks are linked to the consumption of contaminated artisanal products—such as açaí, bacaba, and sugarcane juice—and is associated with higher parasite loads and more severe acute illness.

According to media, there is an unusual, significant spring increase in Influenza A and respiratory viruses in multiple regions, including Santiago, Biobío (Concepción), and Chiloé.

There are warnings regarding system overload of Emergency services in Chile from increased respiratory consultations, but most cases are mild; severe cases and ICU occupancy remain lower than in winter.

Influenza continues to cause nationwide, multi-regional outbreaks, with activity spreading from southern to northern provinces. The surge has led to school closures in many areas and hospitals operating beyond capacity in several provinces. Influenza A (H3N2) remains the dominant strain, and authorities warn of further escalation during winter.

Depuis janvier 2025, 56 cas de paludisme (malaria) ont été signalés au Cap-Vert, la majorité d'entre eux en septembre et octobre. Environ 41 % (23 cas) sont considérés comme importés; des enquêtes sur une éventuelle transmission locale sont actuellement en cours.

Aucune information n'est disponible à ce jour sur les espèces Plasmodium responsables.

La saison des pluies (de juillet à octobre) favorise la prolifération des moustiques et donc un risque accru de transmission. Bien que le Cap-Vert ait été officiellement certifié exempt de paludisme en janvier 2024, les cas actuels indiquent une possible résurgence de la transmission locale.

Depuis mai 2024, des cas de rage ont été détectés chez des otaries à fourrure du Cap sur les côtes ouest et nord de l'Afrique du Sud. En janvier 2025, 55 cas confirmés en laboratoire avaient été signalés, dont 39 dans la province du Cap-Occidental et 16 dans celle du Cap-Nord.

En juin 2025, un premier cas de rage a été signalé chez une otarie dans la lagune de Walvis Bay, en Namibie.

Il s'agit de la première épidémie documentée de rage avec transmission continue entre otaries chez les mammifères marins. Des études rétrospectives montrent que l'infection chez les otaries existe depuis au moins août 2022.
