29 hours ago · Coronavirus Disease (COVID-19) is a disease caused by the newly emerged coronavirus SARS-CoV-2. COVID-19 is a nationally notifiable disease and reporting cases to CDC is supported by routine case notification through the National Notifiable Diseases Surveillance System (NNDSS), as well as resources provided through the CDC COVID-19 response. >> Go To The Portal
You tested positive or have symptoms.Isolate away from other people. Stay home for at least 5 days and follow steps for isolation.Do not travel for 10 days.
CDC strongly encourages everyone who uses a self-test to report any positive results to their healthcare provider. Healthcare providers can ensure that those who have tested positive for COVID-19 receive the most appropriate medical care, including specific treatments if necessary.
According to the Centers for Disease Control and Prevention, some people who contract COVID-19 can have detectable virus for up to three months, but that doesn't mean they are contagious. When it comes to testing, however, the PCR tests are more likely to continue picking up the virus following infection.
>People who have recovered from COVID-19 can continue to test positive for up to 3 months after their infection.
Stay home, except to get needed medical care. Stay home from work and school, and avoid other public places including the store. If you must go out, avoid public transportation or ridesharing/taxis. Stay far away (6 feet or more) from other people. Wear a mask at all times and wash or sanitize your hands often.
Do not travel until a full 10 days after your symptoms started or the date your positive test was taken if you had no symptoms.
Most people with COVID-19 are no longer contagious 5 days after they first have symptoms and have been fever-free for at least three days.
Because of the limited length of follow-up, it remains unclear how long immune protection will last after previous infection
See full answerIf a previously infected person experiences new symptoms consistent with COVID-19 3 months or more after the date of the previous illness onset (or date of last positive viral diagnostic test [RT-PCR or antigen test] if the person never experienced symptoms), the person should undergo repeat viral diagnostic testing. However, serologic testing should not be used to establish the presence or absence of SARS-COV-2 infection or reinfection. These people who have a positive test result should be considered infectious and remain isolated until they again meet criteria for discontinuation of isolation or of transmission-based precautions. Contact tracing during the person’s second episode of symptoms is warranted.
Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick.
Omicron is now the most dominant strain of coronavirus in the U.S., and its incubation period may be shorter than those of previous variants. Research is just beginning. But some scientists who've studied Omicron and doctors who've treated patients with it suggest the right number might be around 3 days.
It is important to remember that some people with antibodies to SARS-CoV-2 may become infected after vaccination (vaccine breakthrough infection) or after recovering from a past infection (reinfected).
