COVID-19 is thought to spread mainly through close contact from person-to-person. Some people without symptoms may be able to spread the virus.
COVID-19 may also be spread by a person touching a surface or object that has the virus on it, then touching their own mouth, nose, or eyes. This is not thought to be the main way this virus is spreading.The virus that causes COVID-19 spreads very easily between people in the following ways:
- Between people who are in close contact with one another (generally being within 6 feet (2 meters) for a combined total of 15 minutes or more over the course of 24 hours).
- Through respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people nearby or be inhaled into the lungs.
- COVID-19 may be spread by people who are not showing symptoms.
Most COVID-19 illnesses are mild with fever and cough. The vast majority of people with novel coronavirus infection do not require hospital care. A smaller percentage of people get severely ill with lung and breathing problems.
Older adults and people of any age with underlying health conditions are at an increased risk for severe illness. Severe illness means that someone with COVID-19 may require hospitalization, intensive care, a ventilator to help them breathe, or they may die.
The CDC has identified that people within the following groups may be at an increased risk for getting COVID-19 or severe illness, regardless of age: racial and ethnic minority groups; people who are pregnant or breastfeeding; people experiencing homelessness; people with disabilities; and people with developmental and behavioral disorders.
If you test positive for COVID-19, isolate away from others and follow the instructions at https://covid.southernnevadahealthdistrict.org/for-cases/.
I have had close contact with someone who tested positive for COVID-19 — now what?
If you have had close contact with someone who has COVID-19, you are required (per NAC 441A.280) to maintain quarantine (stay home and away from others).
The CDC continues to endorse quarantine for 14 days after your last close contact as the safest option to reduce the risk of spreading illness. However, according to new CDC guidance you may end quarantine after 10 days if you do not have any symptoms during this 10-day period. If symptoms develop at any time, you must isolate yourself away from others and get tested.
After your quarantine period you should continue to limit your contact with others as much as possible, and always wear a face mask when you are around people who do not live with you.The state of Nevada requires people who have had close contact with someone who has COVID-19 to sign a Declaration of Self-Quarantine. Sign the declaration here.
