Some people of Chinese and Asian decent are facing stigma in their communities, regardless of whether they been exposed to COVID-19. Stigma involves stereotyping and discriminating against an identifiable group of people, a place, or a nation. It’s understandable to be alarmed by 2019 Novel Coronavirus. But no amount of fear can excuse prejudice and discrimination against people of Asian descent or who appear to be of Asian descent.
FACT: People—including those of Asian descent—who have not recently traveled to China or been in contact with a person who is a confirmed or suspected case of COVID-19 are not at greater risk of acquiring and spreading COVID-19 than other Americans.
What You Can Do
What Schools Can Do
People from China in the United States may be worried or anxious about friends and relatives who are living in the region. Facing stigma can make fear and anxiety worsen. Social support during this outbreak can help them cope.

- Instruct patients with symptoms of any respiratory infection to wear a facemask BEFORE entry to the healthcare facility.
- Consider posting visual alerts (e.g., signs, posters) at the entrance and in strategic places to provide patients with instructions about using facemasks (see attached example).
- Ensure patients with symptoms of respiratory infection are not allowed to wait among other patients seeking care and go through rapid triage procedures.
- If a patient meets criteria for evaluation for COVID-19 (see above):
- Place patient in an airborne infection isolation room (AIIR), if possible.* Implement airborne and contact precautions, and ensure all healthcare personnel use an N95 respirator, gown, gloves, and eye protection (e.g., goggles or face shield that covers the front/sides of the face) when in the patient room.
- Limit visitors and healthcare personnel from entering the room of a patient who meets the above criteria, especially during aerosol-generating procedures (e.g., NP and OP specimen collection).
- If a patient is being evaluated for COVID-19, do not use the airborne infection isolation room (AIIR) for 2 hours after the patient leaves the room, if possible.
- If a patient calls ahead to alert an outpatient healthcare facility of the need to be evaluated for 2019-nCoV and meets the above criteria, encourage the patient to be seen at the end of the day.
- For environmental cleaning and disinfection procedures, use of EPA-registered, hospital-grade disinfectant is appropriate for COVID-19 in healthcare settings.
*For facilities that do not have an AIIR, testing should be performed by a healthcare provider using an N95 respirator, gown, gloves, and eye protection (e.g., goggles or face shield that covers the front/sides of the face) in a private room with the door closed. Avoid use of that room for additional patients until the room has been cleaned with a 1:10 dilution of bleach solution and 2 hours have passed, if possible.
