For those who are traveling abroad
Last Updated October 16, 2024
About infectious diseases that should be noted when traveling abroad
There are various infectious diseases that are rarely seen or are not well known in Japan, and that are at high risk of infection overseas.
Restrictions on travel abroad have been relaxed, and traffic with and from overseas has become more active. As a result, it is expected that the number of people suffering from infectious diseases that are prevalent overseas will increase.
Before traveling abroad, acquire the correct knowledge in advance about how to prevent infectious diseases and the status of outbreaks in each region, and have a safe and enjoyable time.
For more information about infectious diseases that are prevalent overseas, see About Import Infectious Diseases.

There are various infectious diseases that may occur depending on the behavior at the destination, but general precautions are as follows.
The most common is food and water-borne digestive infections. There are enterohemorrhagic Escherichia coli (such as O157), hepatitis A, cholera, bacterial dysentery, typhoid and parachiphus.

There are many diseases transmitted by mosquito bites, such as yellow fever, malaria, dengue fever, Zika virus infection, West Nile fever, and Chikungunya fever. Care must be taken especially in tropical and subtropical regions. It is also necessary to pay attention to fleas and ticks.
- Wear long sleeves and long pants to avoid exposing your skin.

Dogs, monkeys, rodents (such as rats) and birds can have a variety of pathogens, such as rabies and bird flu.

There may be parasites on watersides such as rivers, lakes, and swamps.

By touching the mouth, nose, eyes, etc. with a hand with a pathogen, the pathogen enters the body.
- Let's wash your hands frequently. In particular, hand washing before eating and after the toilet is important.
3.After returning to Japan…
Quarantine stations at airports and ports provide health consultations. If you are unwell at the time of entry, please be sure to consult us.
Also, depending on the infectious disease, you may get sick after a while, even if there is no problem when you return home.
In that case, please inform us in advance of your destination, length of stay, contact with animals, etc., and perform sufficient cough etiquette (wearing a mask, etc.) and consult a medical institution.
