What are the Coronaviruses

Coronaviruses are a group of common viruses. They are named for the crown-like spikes on the surface of the virus. Some coronaviruses only affect animals, but others can also affect humans. Most people get infected with human coronaviruses at some time in their life. This usually causes mild to moderate upper-respiratory infections, like the common cold. But they can also cause more severe illnesses such as bronchitis and pneumonia.

There are several different types of human coronaviruses, including coronavirus disease 2019 (COVID-19) and the Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS) coronaviruses.

Face Masks

Cloth face coverings are one of the most effective ways to help slow the spread of covid-19.  A simple cloth face covering helps to slow the spread of the virus and helps people who may have the virus and do not know it from transmitting it to others. 

*A significant portion of individuals with coronavirus lack symptoms (“asymptomatic”) and that even those who eventually develop symptoms (“pre-symptomatic”) can transmit the virus to others before showing symptoms.  This means that the virus can spread between people interacting in close proximity, even if those people are not exhibiting symptoms.

CDC Cloth Face Mask Guidelines and Tutorial (opens in new window)

Cloth face coverings should:

  • fit snugly but comfortably against the side of the face
  • be secured with ties or ear loops
  • include multiple layers of fabric
  • allow for breathing without restriction
  • be able to be laundered and machine dried without damage or change to shape
