Between September 2022 and  March 2026, over 1’000 confirmed and possible cases of shigellosis and other gastrointestinal infections, including salmonellosis, have been detected in travellers returning from Cabo Verde to several countries in the European Union/European Economic Area (EU/EEA), the United Kingdom (UK), and the United States (US), with new cases still being reported.

Most cases of shigellosis and other gastrointestinal infections, including salmonellosis, were linked to a hotel chain in Santa Maria, Sal Island. The exact source is unknown, but food- or waterborne transmission is likely, with some person-to-person spread also possible.

On 24 Mar 2026, laboratory testing confirmed the presence of yellow fever virus in a deceased red howler monkey (Alouatta seniculus) in Trinidad, with no human cases reported.

The Ministry of Health carried out surveillance and vector control measures in affected areas after the detection.

Monkeys act as sentinel species for the environmental circulation of the yellow fever virus.

Since 2025, EU/EEA countries have seen a rise in dengue cases among travellers returning from the Maldives, though without increased severity. In 2026 so far, at least 46 imported cases have been reported across four countries, continuing a trend that intensified in late 2025. This mirrors a significant surge in dengue cases within the Maldives itself, with 631 cases reported in January 2026 compared to 72 in January 2025.

In 2025, the Robert Koch-Institute (RKI) reported five gonorrhea cases linked to travel in Asia, with pathogens confirmed as extensively drug-resistant (XDR) or multi-drug-resistant (MDR). The cases, recorded between May and December 2025 across various German states, involved men aged 23–50 presenting with symptomatic urethritis. Four infections were likely acquired through heterosexual contacts in Thailand, and one case in China. Two patients reported contact with a sex worker abroad.

As of 20 March 2026, the Campania region of Italy has recorded at least 154 hepatitis A cases (+21 within 24 hours) since the beginning of the year. The increase in cases is suspected to be linked to contamination of bivalve molluscs, prompting intensified control measures across the entire bivalve supply chain.

Cotugno Hospital, the regional reference center for infectious diseases in Naples, is managing 54 hospitalized hepatitis A patients as of 22 March 2026, including eight new admissions to the emergency department on that day alone.

In response, Naples Mayor Gaetano Manfredi issued an emergency ordinance banning the consumption of raw shellfish and related molluscs in all public establishments.
