For those who travel abroad
Last update date April 18, 2024
About infectious diseases that you should be aware of when traveling abroad
There are various infectious diseases that are rarely seen or are not well known in Japan, and are at high risk of infection overseas.
Restrictions on overseas travel have been relaxed, and traffic to and from overseas is becoming 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, learn the correct knowledge in advance about how to prevent infectious diseases and the outbreak situation in each region, and have a safe and enjoyable time.
For more information about infectious diseases that are prevalent overseas, see About imported infectious diseases.

2.General precautions when traveling abroad
Depending on the behavior at your destination, there are various infectious diseases that may occur, but the general precautions are as follows.
The most common type is food and water-borne digestive infections. There are enterohemorrhagic Escherichia coli (such as O157), hepatitis A, cholera, bacterial dysentery, typhoid and paratyphoids.
- Avoid fresh water, boil water and drink or drink mineral water. Be careful about juices with ice and alcoholic beverages.
- Avoid raw vegetables, cut fruits, raw seafood and meat.

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 areas. Also, care must be taken for fleas and ticks.
- Wear long sleeves and long pants to avoid exposing the skin.

Dogs, monkeys, rodents (such as rats) and birds can have a variety of pathogens, such as rabies and bird flu.
- Don't approach or touch animals unnecessarily.
Watersides such as rivers, lakes, and swamps, may have parasites.
- In endemic areas, avoid walking barefoot or entering the water.
The pathogen enters the body by touching the mouth, nose, eyes, etc. with a hand with a pathogen.
- Let's wash your hands frequently. In particular, hand washing before meals and after the toilet is important.
3.After returning to Japan…
Health consultation is provided at quarantine stations at airports and ports. If you feel unwell at the time of entry, please be sure to consult with us.
Also, depending on the infectious disease, even if there is no problem when returning to Japan, you may feel sick after a while.
In that case, please inform us in advance of your destination, period of stay, contact with animals, etc., and perform sufficient cough etiquette (wearing a mask, etc.) and consult a medical institution.
