The Facts about Coronavirus ~Prevention~

Do not be confused with false rumors about the virus! -Be afraid right and prevent right –

As the novel coronavirus spreads in every corner of the world, and as people get worried, news or rumors which are not always true are getting around.

We provide you with the information about infection prevention so that you do not trust all rumors you have checked and then spread fake news or take wrong actions.

*This article is based on the information provided by WHO (World Health Organization) and Fact-check Initiative Japan (FIJ).

1. Even if you sunbathe or you are exposed to temperature of 25°C or above, you cannot prevent infection of the novel coronavirus.

You can be infected with the novel coronavirus even if the weather is good and the temperature is high. In fact, there are confirmed COVID-19 cases in warm countries. In the first place, the normal human body temperature is in the range of 36.5 to 37 C°; the virus doesn’t die off at lower temperature than it.

Also, it is incorrect that the virus does not spread in warm and humid areas, and that cold air and snow can kill the virus.

2. Even if you drink hot water, you cannot prevent infection of the novel coronavirus.

In every corner of the world, it is said that  “Since viruses are weak against heat, you can prevent infection if you drink 26~27-degree warm water.” or  “It is recommended that you drink hot water”, but these are wrong. Generally, it is recognized that viruses are weak against heat, but it does not necessarily mean that they are no longer active.

Likewise, you cannot protect yourself from the novel coronavirus by taking a hot bath or taking a shower.

3. Hand dryers do not kill the novel coronavirus.

The important thing is to wash your hands frequently with alcohol-based hand rub or soap. Though hand dryers themselves do not prevent virus infection, it is effective for infection prevention to dry up your hands with towel or dryer after washing your hands.

4. Even if you spray disinfectant or bleach on your body, you cannot prevent infection of the novel coronavirus.

If you spray disinfectant or bleach, it causes serious damages to your skin or eyes. Also, it can be very dangerous if chemicals get into your body by any chance.

You should use these chemicals properly.

5.Even if you drink liquor, you cannot prevent infection of the novel coronavirus.

Rather, drinking alcohol frequently/excessively is not good for your health.

6. Even if you can hold your breath for more than ten seconds without coughing or feeling discomfort, it does not prove that there is no infection.

Most common symptoms of the novel coronavirus are said to be cough, fatigue and fever. Only a medical check can confirm infection, not a breathing test.

7. The novel coronavirus does not be transmitted by flies or mosquitoes.

To date, there has been no news or scientific evidence which shows fly or mosquito carry the novel coronavirus. The virus spreads through droplets by coughing, sneezing or talking. In addition to that, you can be infected with the coronavirus when you touch things which the virus lands on and then touch your eyes, nose or mouth without washing your hands. 

8. Rumors tell that certain food items and drinks are effective for preventing infection, but none of these have been scientifically proven.

There is no evidence whatsoever that hot peppers can prevent or cure the novel coronavirus.

There are also no trustworthy or well-grounded research results to show that certain type of seaweeds, sea lettuce, has an effect for preventing the novel coronavirus.

Also, some say that drinking tea (or green tea) prevents infection, even though there is possibility that green tea has an ingredient which is effective for restraining viruses, until now no research results prove its actual effect in the lab or on human body.  

Moreover, some information sources tell that eating garlic is effective for preventing the novel coronavirus, but there is no scientific ground for that.

Also, a number of rumors tell you that vitamin-D is effective for preventing the novel coronavirus and that infected people lack vitamin-D, but National Institute of Health and Nutrition reports that there are no such effects confirmed until now.

So, what should we do for prevention?

In order to prevent infection, it is useful and reasonable to keep distance from other people, to sterilize things or places you touch often and to frequently wash your hands with alcohol-based hand rub or soap. It is also important that you do not touch your eyes, nose, mouth or other parts of your face. Please refer to other articles of ours about how to wash your hands or what kind of places you should avoid in order not to spread infection. 

By learning and carrying out proper infection prevention measures, let’s help ourselves and our precious people guard against the novel coronavirus!
