This page includes advice from the World Health Organization (WHO), a prominent public health organization. Advice on ways to protect yourself and prevent the spread of COVID-19. The attachments below guide general and specific topics related to the pandemic.
The COVID-19 vaccines are designed to prevent the SARS-CoV-2 virus that causes COVID-19. The vaccines are doses of hope and our best shot of eradicating the pandemic and getting life back to “normal.” Getting the COVID-19 vaccine(s) is an easy step you can take to protect others and help keep you, your family, and your community safe.
COVID-19 Variants:
According to WHO, viruses constantly change through mutation, and sometimes these mutations result in new variants of the virus. Some variants emerge and disappear while others persist. As new variants emerge, public health organizations will continue to monitor all variants of the virus that causes COVID-19 nationally and internationally.

Make your environment safer:
The risks of getting COVID-19 are higher in crowded and inadequately ventilated spaces where infected people spend long periods of time together in proximity.
Outbreaks have been reported in places where people have gathered, often in crowded indoor settings and where they talk loudly, shout, breathe heavily or sing such as restaurants, choir practices, fitness classes, nightclubs, offices and places of worship.
To make your environment as safe as possible:
-
Avoid the 3Cs: spaces that are closed, crowded, or involve close contact.
-
Meet people outside. Outdoor gatherings are safer than indoor ones, particularly if indoor spaces are small and without outdoor air coming in.
-
If you can’t avoid crowded or indoor settings, take these precautions:
-
Open a window to increase the amount of natural ventilation when indoors.
-
Wear a mask (see above for more details).
