However, many people dont experience any of those symptoms at all. Using real-time PCR to detect virus is unable to conclude whether the viral genetic material detected actually comes from virus which is able to infect people, or dead or dying virus. chills or night sweats cough sore throat tiredness (fatigue) difficulty breathing headache muscle pain (myalgia) loss of sense of smell (anosmia) distortion of sense of taste (dysgeusia) nausea and vomiting joint pain loss of appetite runny nose acute blocked nose (congestion).

Data from the ZOE Covid study predicted in December, 1,418 people a day would go on to experience symptoms for longer than 12 weeks. That incubation period is just about three days, compared to the Delta variant's five-day incubation period, and the original SARS-CoV-2 virus' incubation period of more than 5 days, according to a December 2021 report published in the CDC's Morbidity and Mortality Weekly Report (MMWR). Swabs from PCR tests, which are sent to labs for analysis, can show if the variant causing the infection looks like Omicron, Delta or something else. Hospitals are seeing more patients now compared to earlier surges have milder symptoms and are seeing more incidental discovery of the disease, Cesar Arias, MD, PhD, chief of the division of infectious diseases at Houston Methodist Hospital and co-director of the Center for Infectious Disease Research at the system's research institute, told Becker's.
