PSA Yokohama

The number of influenza cases usually peaks around this time of year. Symptoms typically affect the entire body and can include fatigue and aching joints, in addition to the sudden onset of a fever over 38℃, a cough, a sore throat and a headache.

Please put even more effort into taking measures to prevent infection.

[To prevent catching it]

After arriving home, you should wash your hands for at least 20 seconds.

Keep rooms humidified at 50-60%, the appropriate level.

Get enough sleep and eat balanced meals.

Those with underlying medical conditions such as asthma, heart disease, or diabetes, as well as pregnant women, infants and the elderly are prone to symptoms becoming severe. Please take solid measures to prevent infection.

[To prevent infecting others]

If you catch influenza, take time off school or work.

Make sure you wear a mask.

Even after your temperature has gone down, you may still be contagious, so recuperate at home for around 3 days after your temperature returns to normal.

You should be on the alert for infectious gastroenteritis from Norovirus too.

If you catch norovirus, you will experience symptoms such as vomiting, diarrhea, stomachache, and fever. For a week, in longer cases, sometimes a month after the symptoms such as diarrhea have gone, the virus will still be present in feces.

[To prevent catching it]

Applying heat when preparing food is important! Norovirus becomes non-infectious if it is heated for over 90 seconds at 85-90°C.

Regular hand washing! Wash your hands with soap before cooking and after going to the toilet etc.

In some cases of norovirus infection, there may be no symptoms, so you could spread it without even realizing. Let’s prevent the spread of infection through thorough handwashing.
