For details, please refer to "COVID-19 Infectious Diseases" (Yokohama City Public Health Center).

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.
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.

To prevent enterohemorrhagic Escherichia coli infection, wash your hands thoroughly, and if symptoms (such as bloody stools) suspected of being infected with enterohemorrhagic Escherichia coli appear, do not take diarrhea and consult a medical institution as soon as possible. Let's go.

Food poisoning due to seafood parasites, Anisakis, is increasing.
Anisakis, which enters the mouth with seafood, can penetrate into the inner wall of the stomach and intestines, causing severe abdominal pain and vomiting.
In some cases, shime mackerel made at home was the cause, and cooking at home also requires attention.
For prevention, cooking (60 ° C, 1 minute or more), refrigeration (-20 ° C, 24 hours or more), and removal of anisakis in bright places are effective.
It is also known that when seafood dies, Anisakis, which was parasitic on the internal organs, moves to the muscles.
When you catch fish yourself, it is also effective to remove internal organs immediately.
For details, please refer to the following website.

• Let's prevent food poisoning due to anisakis (outside site)(Ministry of Health, Labour and Welfare)

• When you return home, wash your hands carefully with running water and soap for at least 20 seconds.
• Wash your fingers, wrinkles, nails, and wrists between your fingers.
• Get enough nutrition and rest and increase your body's resistance.

• Wear a mask if you have a cough or sneeze.
• If you get flu, take a break from school or work.
  (Generally, it is said that the virus is excreted from the nose and throat for 3 to 7 days after onset.)
  (The School Health and Safety Act states that attendance is suspended until 5 days have passed after the onset and 2 days after the fever has resolved (3 days for infants).)

• If you think you have done so, be sure to wear a mask and consult a medical institution as soon as possible.
• If you do not answer the call, breathing is fast, breathless, chest pain continues, and symptoms worsen, it is a sign of severe disease. I'll see you right away.

Winter is the season when infectious diseases such as norovirus and influenza reach the epidemic season.
Let's prevent infectious diseases together by ensuring that each person thoroughly washes hands.

• Use soap to lather well and rinse thoroughly.
• Carefully wash areas where dirt is likely to remain (finger tips, between fingers, wrists, etc.).
• After using the toilet, treat your vomit, and wash your hands frequently, such as when returning home or before and after cooking.

The Yokohama City Public Health Center has created posters for correct hand washing enlightenment and norovirus epidemic warning. Please print it out freely and use it.

In the mouth of animals, nails and manure may have pathogens that cause infectious diseases in humans.
Avoid excessive contact, and wash your hands after contacting or cleaning the toilet.
Also, do not touch wild animals unnecessarily (be careful when traveling abroad).

In regions such as Central and South America and Asia, mosquito-borne "Zika virus infection (Zika fever)" has occurred.
Zika virus infection during pregnancy can cause fetal microcephaly, so those who may become pregnant or pregnant women should refrain from traveling to endemic areas.

Vaccinations is expected to increase resistance (immunity) by vaccinating a vaccine that confirms the effectiveness of disease prevention, and to prevent the disease from becoming more severe.
It is one of the measures to protect your life and health, not only to prevent the spread of infectious diseases, but also to prevent the spread of infectious diseases.
The Vaccination Law stipulates the type of vaccination, implementation method, remedy system, etc.
The handling of "regular vaccinations" carried out by each local government, including Yokohama City, and "voluntary vaccinations" that are inoculated individually are different.
For more information, please see "About Vaccinations."

It was a great season for hiking.
There have been many cases of food poisoning caused by accidentally eating poisonous plants as edible plants when picking wild plants.
It is difficult to distinguish plants only by leaves and roots, and it is very dangerous to judge amateurs.
Plants that cannot be reliably determined to be edible should not be picked, eaten, sold, or given to others.
