US health agency issues Level 1 travel notice for paratyphoid fever in Yemen

The US Centers for Disease Control and Prevention (CDC) has issued a Level 1 travel notice for Yemen, prompting health authorities to advise visitors to remain vigilant. The advisory, published on 26 August 2026, highlights emerging health concerns for those visiting the country.

Level 1 is the lowest tier in the CDC’s travel health notice system. It indicates that travellers should practice usual precautions rather than implementing specific, heightened measures. This classification suggests a manageable risk profile for the general travelling public.

The notice was triggered by reports of paratyphoid fever cases in travellers returning from Yemen. While the source material does not specify the exact number of infections or the precise timeframe of the outbreak, the pattern among returning visitors has prompted the agency to issue the formal advisory.

Paratyphoid fever is a bacterial infection that can be contracted through contaminated food or water. The CDC emphasises that the disease can be prevented by maintaining safe eating and drinking habits while in the region.

Specific regions within Yemen affected by the fever are not detailed in the current notice. Consequently, the advice applies broadly to travellers visiting the country, urging them to remain mindful of hygiene and food safety standards.

The advisory serves as a reminder for health-conscious travellers to stay informed about local health conditions. By following standard precautions, visitors can reduce their risk of contracting paratyphoid fever during their stay in Yemen.
