In February 2020 the World Health Organization announced an official name for the disease that is causing the 2019 novel coronavirus outbreak. The new name of this disease is coronavirus disease 2019, abbreviated as COVID-19.
How does the virus spread?
The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs, sneezes or talks. These droplets can land in the mouths or noses of people who ae nearby possibly be inhaled into the lungs. Spread is more likely when people are close in contact with one another (within about 6 feet).
Should I use soap and water or hand sanitizer to protect against COVID-19?
Handwashing is one of the best ways to protect yourself and your family from getting sick. Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol.
What cleaning products should I use to protect against COVID-19?
Clean and disinfect frequently touched surfaces such as tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks. If surfaces are dirty, clean them using detergent or soap and water prior to disinfection. To disinfect, most common EPA-registered household disinfectants will work. See CDC’s recommendations for household cleaning and disinfection.
What is contact tracing?
Contact tracing is used by health departments to prevent the spread of infectious disease. In general, contact tracing involves identifying people who have an infectious disease (cases) and their contacts (people who may have been exposed) and working with them to interrupt disease transmission. For COVID-19, this includes asking cases to isolate and contacts to quarantine at home voluntarily.
Contact tracing for COVID-19 typically involves:
- Interviewing people with COVID-19 to identify everyone with whom they had close contact during the time they may have been infectious,
- Notifying contacts of their potential exposure,
- Referring contacts for testing,
- Monitoring contacts for signs and symptoms of COVID-19, and
- Connecting contacts with services they might need during the self-quarantine period.
To prevent the further spread of disease, COVID-19 contacts are encouraged to stay home and maintain social distance (at least 6 feet) from others until 14 days after their last exposure to a person with COVID-19. Contacts should monitor themselves by checking their temperature twice daily and watching for symptoms of COVID-19.
Who is considered a close contact to someone with COVID-19?
For COVID-19, a close contact is defined as anyone who was within 6 feet of an infected person for at least 15 minutes starting from 48 hours before the person began feeling sick until the time the patient was isolated.
