How long does the delta variant last

Research suggests that changes to the spike protein may make the Delta variant up to 50% more transmissible than other COVID-19 variants. For people who haven’t had the coronavirus vaccine, the Delta variant may cause more severe illness than the original strain of the virus.

These variants seem to spread more easily and quickly than the dominant strain, and they also may cause more severe illness, but more research is needed to make a determination.

People with COVID-19 can spread the virus to other people for 10 days after they develop symptoms, or 10 days from the date of their positive test if they do not have symptoms. The person with COVID-19 and all members of the household should wear a well-fitted mask and consistently, inside the home.

“Some symptoms of COVID-19 linger longer than others,” says Dr. Septimus. “In particular, fatigue and loss of taste and smell can persist beyond the period of contagion.”

While uncomfortable and/or inconvenient, Dr. Septimus adds that these lingering symptoms aren’t too worrisome for most people.

Persons who have tested persistently or recurrently positive for SARS-CoV-2 RNA have, in some cases, had their signs and symptoms of COVID-19 improve. When viral isolation in tissue culture has been attempted in such persons in South Korea and the United States, live virus has not been isolated. There is no evidence to date that clinically recovered persons with persistent or recurrent detection of viral RNA have transmitted SARS-CoV-2 to others.

Despite these observations, it’s not possible to conclude that all persons with persistent or recurrent detection of SARS-CoV-2 RNA are no longer infectious. There is no firm evidence that the antibodies that develop in response to SARS-CoV-2 infection are protective. If these antibodies are protective, it’s not known what antibody levels are needed to protect against reinfection.

● Stay home. Most people with COVID-19 have mild illness and can recover at home without medical care. Do not leave your home, except to get medical care. Do not visit public areas.
● Take care of yourself. Get rest and stay hydrated. Take over-the-counter medicines, such as acetaminophen, to help you feel better.

Known as post-acute sequelae of SARS-CoV-2 infection (PASC), or more commonly as Long COVID, these conditions affect all ages. Long-term effects include fatigue, shortness of breath, difficulty concentrating, sleep disorders, fevers, anxiety and depression.

The following applies to a person who has clinically recovered from SARS-CoV-2 infection that was confirmed with a viral diagnostic test and then, within 3 months since the date of symptom onset of the previous illness episode (or date of positive viral diagnostic test if the person never experienced symptoms), is identified as a contact of a new case. If the person remains asymptomatic since the new exposure, then they do not need to be retested for SARS-CoV-2 and do not need to be quarantined. However, if the person experiences new symptoms consistent with COVID-19 and an evaluation fails to identify a diagnosis other than SARS-CoV-2 infection (e.g., influenza), then repeat viral diagnostic testing may be warranted, in consultation with an infectious disease specialist and public health authorities for isolation guidance.

In clinical trials, vaccine side effects were mild, self-limiting, and similar to those seen in adults and with other vaccines recommended for children. The most common side effect was a sore arm. COVID-19 vaccines have undergone – and will continue to undergo – the most intensive safety monitoring in U.S. history.

Additionally, 50% of people reported systemic side effects (e.g., fatigue, headache, or muscle pain) after their first dose, which jumped to about 70% after the second dose. Chills and fever, which were reported by only about 9% of people after their first dose, went up to about 30% after the second dose.
