Those suffering from post-acute sequelae of COVID-19 frequently have difficulty concentrating and memory problems, sometimes called “brain fog.” This impairment is a common symptom in those with severe fatigue of any cause.
"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.
Long COVID is a range of symptoms that can last weeks or months after first being infected with the virus that causes COVID-19 or can appear weeks after infection. Long COVID can happen to anyone who has had COVID-19, even if their illness was mild, or if they had no symptoms.
Benefits of Vaccination Outweigh the Risks Serious side effects that could cause a long-term health problem are extremely unusual following any vaccination, including COVID-19 vaccination.
Immunity is complicated and, yes, you can still get reinfected with COVID-19. In fact, a recent study found that unvaccinated adults were twice as likely to get reinfected with COVID-19 than those who got vaccinated after they'd recovered from their illness.
Any time you catch a virus and recover from the illness, you retain antibodies. These antibodies help your body fight off future infections so that you either don't get sick or have milder symptoms.
While some have suggested that most people will eventually get the coronavirus, you should do your best to avoid infection with Omicron—there is no justification for deliberately getting infected so you have what you think will be a mild illness that will provide you with more immunity going forward, the doctors say.
The Omicron variant spreads more easily than earlier variants of the virus that cause COVID-19, including the Delta variant. CDC expects that anyone with Omicron infection, regardless of vaccination status or whether or not they have symptoms, can spread the virus to others.
