Is it possible to be infected with a novel coronavirus infection through food?

The main routes of transmission of new coronavirus infection are considered to be droplet infection and contact infection. As of April 1, 2020, there have been no cases reported to have been infected with a novel coronavirus infection through food (including vegetables and fruits that are eaten raw and fresh seafood).
In addition, when serving food or meals, you may come into contact with an unspecified number of people, so be careful of contact infections (*). The same applies to tableware, so please be careful including clean handling.
* Contact infection is one of the main routes of infection for new coronavirus infections.
Coronavirus has been found to be vulnerable to heat (above 70 ° C for a certain period of time) and alcohol (above 70%, commercially available alcohol for hand disinfection). At each stage of manufacturing, distribution, cooking, sales, and catering, we carry out regular food poisoning prevention such as physical condition management of food handlers, frequent hand washing, hand disinfection with alcohol for hand disinfection, cough etiquette, etc. If general hygiene is in place, don’t worry. As a general caution from WHO, “Avoid consumption of raw or undercooked animal meat and meat products, and be careful when handling and cooking them.”

How is the new coronavirus infection transmitted?

At present, there are two possibilities: droplet infection (Hitotsukansen) and contact infection.
(1) Droplet infection The virus is released together with the droplets (sneezing, coughing, brim, etc.) of the infected person and another person inhales the virus through the mouth or nose to become infected.
* Scenes to be aware of infection: When spending a certain amount of time indoors, etc. when the distance between each other cannot be secured sufficiently
(2) Contact infection After the infected person holds his / her sneezing and coughing, he/she turns around by himself/herself. If you touch the item, the virus of the infected person will be attached. When an uninfected person comes into contact with the part, the infected person’s virus attaches to the uninfected person’s hand and becomes infected without directly contacting the infected person.
* Examples of infected areas: straps for trains and buses, doorknobs, handrails for escalators, switches, etc.

Is it true that the new coronavirus is derived from bats?

In recent years, two types of coronaviruses, which are considered to be of animal origin, have occurred and infected humans and became prevalent. “Severe acute respiratory syndrome (SARS)” that occurred in 2002 and “Middle East respiratory syndrome (MERS)” that have occurred since 2012. Although no definitive evidence that the new coronavirus is of animal origin has been found, it is possible that the bat was the origin of this new coronavirus because its gene sequence is close to the SARS-like coronavirus derived from bats. Is being considered.

What kind of virus is “Coronavirus”?

So far, seven kinds of “coronaviruses” that infect humans have been found, and one of them is the so-called “new coronavirus (SARS-CoV2)” that has been a problem since last December. Of these, four types of viruses account for 10 to 15% (35% during the epidemic) of common cold causes, and many are mild. The remaining two viruses are “Severe Acute Respiratory Syndrome (SARS)” that occurred in 2002 and “Middle East Respiratory Syndrome (MERS)” that has occurred since 2012. Coronaviruses can infect all animals, but rarely infect other animals of different species. It is also known to lose its infectivity by alcohol disinfection (70%).
