The Port Health Division of the Department of Health of the HKSAR Government recently reminded the public about the health risks for travellers who will visit Canada, the United States and Mexico during the FIFA World Cup 2026, which will take place from 11 June to 19 July 2026. With a large number of international visitors expected to converge on the host cities, the risk of transmission of communicable diseases is heightened in crowded settings such as stadiums, fan zones and public transport. Travellers should be particularly aware of the following diseases:

• Measles
• Seasonal Influenza and COVID-19
• Dengue Fever and Zika Virus Infection
• Sexually Transmitted Infections

Travellers should also be aware of environmental health risks, including extreme heat at venues and food and water safety concerns in Mexico.

The Port Health Division advise travellers attending the FIFA World Cup 2026 to take the following precautions:

• Ensure vaccination status is up to date before departure, in particular the MMR vaccine against measles (two doses required) and seasonal influenza vaccine. Pregnant women who are not immune to measles are advised not to travel to affected areas. Travellers who are unsure of their vaccination status should consult their family doctor for advice;
• Travellers visiting Mexico should apply DEET-containing insect repellent, wear long-sleeved clothing, and stay in air-conditioned or screened accommodation. Pregnant women or those planning pregnancy are advised not to travel to Mexico due to the risk of Zika virus infection; those who must travel should strictly follow mosquito bite prevention measures throughout their stay and for at least three months after return.
• In the southern United States and Mexico Monterrey, stay hydrated, wear light-coloured loose-fitting clothing and apply sunscreen, limit outdoor activity during peak heat hours (10am to 4pm). Seek immediate medical attention if heat stroke is suspected;
• In Mexico, drink only bottled or boiled water and consume food from reputable establishments only;
• Maintain good personal hygiene, wash hands frequently and avoid touching the mouth, nose or eyes. Wear a surgical mask in crowded or poorly ventilated places. Avoid close contact with persons who are unwell;
• Anyone who develops fever, rash, respiratory symptoms, joint pain or diarrhoea during travel or within three weeks of returning to Hong Kong should seek medical attention promptly and inform their doctor of their travel history.
