As international travel restarts during the worldwide COVID-19 pandemic, travellers visiting certain regions remain at risk of illnesses such as typhoid and paratyphoid.

At-risk travellers need clear guidance on how to prevent infection and should be offered vaccination if recommended for their planned destinations.
