Travel-related typhoid and paratyphoid infections have surged to unprecedented levels across the UK, with health authorities recording 702 cases in 2024.
The UK Health Security Agency revealed these provisional figures represent an 8 per cent increase from the previous year and the highest number ever documented in England, Wales, and Northern Ireland.
The record-breaking statistics have prompted urgent warnings from health officials, who are calling on travellers to take comprehensive precautions before journeys abroad.
The sharp rise in these potentially life-threatening bacterial infections has intensified concerns about travel-related disease transmission as international movement continues to recover post-pandemic.

Typhoid fever is a bacterial infection caused by Salmonella bacteria that typically spreads through contaminated food and water.
Without prompt treatment, the infection can lead to serious complications and prove fatal.
The disease poses particular risks to travellers visiting regions where sanitation standards may be lower or where the bacteria is more prevalent.
Paratyphoid fever, whilst similar to typhoid, is caused by a related but distinct strain of Salmonella bacteria.
Both infections share similar transmission routes and can cause severe illness, making prevention measures crucial for those planning international travel.
Free typhoid vaccines are available at GP surgeries for eligible travellers, with the UKHSA directing people to consult the Travel Health Pro website for comprehensive guidance before international trips.
However, no vaccine currently exists for paratyphoid fever, making other preventative measures particularly important for those visiting affected regions.
The health body emphasises that travellers should investigate vaccination requirements and health precautions well in advance of their journeys, even for familiar destinations or when visiting friends and relatives abroad.
These preventative steps become especially critical given the record-breaking infection rates and the potentially severe consequences of contracting either disease whilst travelling.

Beyond typhoid concerns, the UKHSA reported that imported malaria cases remain at "concerning levels" with 1,812 diagnoses in 2024, despite a slight decrease from the previous year.
Dr Philip Veal, consultant in public health at the UKHSA, said: "We are seeing high levels of infections such as malaria and typhoid in returning travellers.
"It is important that travellers remain alert and plan ahead of going abroad, even if you're visiting friends and relatives abroad or it's somewhere you visit often."
He advised checking the Travel Health Pro website for vaccine information, anti-malaria tablets, and guidance on avoiding gastrointestinal infections.
Dr Veal added that pregnant women or those trying to conceive should seek healthcare advice before planning trips.
