Novel Coronavirus Infection Disease Related Information


The number of people infected with coronavirus variants, which are more contagious and prone to become severe in even young people, is increasing. For your safety, please check the following where we have published important information concerning the virus and procedures to take. It is imperative that we work harder than ever to take measures against infection and share a sense of responsibility to prevent the spread of the virus.


For All Members of the School of Science

 School of Science’s New response policy for COVID-19 after May 8

1. Wearing masks

Wearing a mask is based on respecting the subjective choice of individuals and entrusting it to individual judgment. However, please respond appropriately in the following cases.

*When the instructor in charge of the class determines that it is necessary to wear mask due to the style or method of the class, or not wearing one when the instructor in charge of the class determines that masks interfere with the operation of the class.*The following situations where wearing a mask is effective in the "Review of the concept of wearing a mask" decided by the government on February 10.
・When visiting medical institutions or facilities for the elderly, etc.・When travelling on crowded trains or buses, such as during rush hours.・When a person with a high risk of becoming seriously ill goes to a crowded place during a period when infection is spreading, etc.

2. Implementation of basic infection control measures

Avoiding the “Three Cs”, “Ensuring distance between people”, “Hand hygiene such as washing hands”, “Ventilation”, etc.

3. If you become infected with the coronavirus infection

The Government of Japan has made the decision to position the novel coronavirus infection as a Category V Infectious Disease under the Infectious Disease Control Law, as they determined that it no longer comes under the category of Pandemic Influenza (Novel Influenza or Re-emerging Influenza) therefore whether to refrain from going out shall be left to individual discretion.
Therefore, we will no longer keep track of infected persons or members who are at risk of infection with the coronavirus. However, if a group of students, faculty or staff are affected at the same time and within the same activity unit, which is the conventional guideline of an outbreak (5 or more affected people in the same activity unit at the same time), and an incident occurs that is considered to have a significant impact on the education, research or administrative activities, please inform us the detail through this form.

4. Social gatherings involving food and beverages

The guidelines for the prevention of novel coronavirus infection at the time of the event (decided by the UTokyo Coronavirus Task Force on May 19, 2022) shall not apply once activity restriction level is reduced to "S."
Although there are no restrictions on holding social gatherings or other events that involve eating or drinking, please be fully aware that the risk of infection increases in such situations. Additionally, if you feel unwell, please refrain from participating.

5. Other remarks

Until now, although the School of Science has made the original manual for COVID-19, after May 8, we decided to stop renewing.From now on, please refer to the UTokyo response policy for COVID-19 and if anything happens, contact below.
