What is COVID-19?

  • COVID-19 is the new respiratory disease spreading around the world and it is caused by a coronavirus. COVID-19 is short for Coronavirus Disease 2019.

The 2019 Novel Coronavirus (2019-nCoV) often referred to as COVID-19 or more simply, the coronavirus is a severe acute respiratory syndrome (SARS-CoV-2) that was newley identified in Wuhan City, Hubei Province, China. Since the first cases were reported, the outbreak has rapidly spread through China and many locations worldwide. Coronaviruses are a large family of viruses that can cause illness in both humans and animals. The illnesses brought about from the coronavirus have ranged from the common cold (ex. Respiratory syndrome, fever, cough, etc.) to more severe sicknesses such as pneumonia and severe acute respiratory syndrome .

PLEASE NOTE: The virus that causes COVID-19 and the one that caused the outbreak of Severe Acute Respiratory Syndrome (SARS) in 2003 are related to each other genetically, but the diseases they cause are quite different. SARS was more deadly but much less infectious than COVID-19, the SARS that may be caused by the coronavirus is a different strain of this so please keep this in mind.


As of April 02, 2020 there have been over 920,000 in at least 180 countries and territories with the highest numbers being in America, Italy, Spain, China and Germany in that order.

In comparison with other countries, Japan is relatively low on the list with only 2,412 cases, and 67 deaths. In our prefecture of Yamanashi there have only been 9 confirmed cases.

There are three parameters to understand in order to assess the magnitude of the risk posed by this novel coronavirus:

Transmission Rate (Ro) - number of newly infected people from a single case

World Health Organization (WHO)'s estimated (on Jan. 23) Ro to be between 1.4 and 2.5.

Case Fatality Rate (CFR) - percent of cases that result in death

3.4% Mortality Rate estimate by the WHO as of March 3

Determine whether asymptomatic transmission is possible

As of now it has been discovered that coronavirus can be spread from someone who carries the virus but shows no symptoms. Thus many governments across the world have decided on a two week incubation period. However, there have been outlier cases such as people who left the diamond princess cruise ship after incubation, returned home and tested positive, as well as a case where someone tested positive in China after 27 days.


How does the virus spread?

  • Droplets from coughing, sneezing and exhaling.

The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth.

People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.


As of March 9th, the World Health Organization says the virus that causes COVID-19 doesn't seem to linger in the air or be capable of spreading through the air over distances of more than about 3 feet. However, there are experts in virus transmission said it's way too soon to know that and there have been multiple advisories to increase that distance to 6 ft / 1.8 meters.

These droplets can travel only short distances through the air and either land on people or land on surfaces that people later touch. Stopping this kind of transmission is why public health officials urge people to wash hands frequently and not touch the face, because that could bring the virus into contact with the nose or mouth.


Who is at high risk?

  • Everyone is at risk of getting COVID-19, but some people are at higher risk of serious illness.

Generally speaking, adults aged 65 and older and people of any age with heart disease, lung disease, and diabetes with complications (such as but not limited to kidney disease heart disease, and neuropathy) may be at higher risk for serious illness from COVID-19.

What are the symptoms?

  • Fever, cough and shortness of breath.

Cough, Shortness of breath and Fever (Yamanashi Prefecture asks citizens to take extra care if a fever of over 37.5° C/99.5° F is developed)

Symptoms may appear 2-14 days after exposure.

Reported illnesses have ranged from mild symptoms to severe illness and death for confirmed coronavirus disease 2019 (COVID-19) cases, and many have recovered.

However, it is important to note that Coronavirus symptoms are expected to remain minor (similar to that of the common cold) for 80% of those infected.

Similar to the infection prevention measures taken for a cold or during flu season, it is important for each and every person to follow the proper coughing/sneezing etiquette and to wash their hands (long enough to sing happy birthday twice).

When should I, and how can I consult a medical professional?

  • Those with a temperature of > 37.5℃ and have developed respiratory symptoms (no matter how minor) and have had close contact with confirmed Coronavirus infectees should contact your local Returnee / Exposed Persons Consultation Center.

  • Those who fulfill the criteria suspecting them of the coronavirus will be directed to a dedicated specialist and move onto testing.

If you have been to a severely affected region (such as Tokyo or Osaka), or if you have come into contact with someone who has, and have had symptoms such as coughing and fever; we ask that you make sure to wear a mask and contact a health center in advance.

In order to protect the health and lives of Yamanashi citizens in the midst of the infectious coronavirus, we believe that it is important to prevent infection by spreading accurate information to help prevent confusion and reduce anxiety amongst the people. Feel free to check back here at any time for the most recent information.

The Returnee / Exposed Persons Consultation Centers have been established with the intention of mitigating anxieties of any potentially infected persons who don’t know what medical facilities to go to. Essentially, first you must call your local center and explain your symptoms. If they decide that you meet the criteria to be tested they will direct you to testing center.
