During this pandemic, we have seen that people without symptoms can transmit coronavirus infection to others. A person with COVID-19 can get infected 48 hours before starting to experience symptoms. As BA, 2 cases continue to dominate across the Midwest and U.S. In the US, COVID-19 cases have been on the rise in Chicago and the city's top doctor said the trend will likely continue in the coming weeks, prompting questions from concerned residents.
Regardless of symptoms, those who test positive are advised to take specific precautions for at least 10 days. People who are close contacts of someone with COVID but are current on their immunizations or have had a confirmed case of COVID-19 in the past 90 days do not need to quarantine, but CDC does recommend that they wear a mask that fits well around others for 10 days after their most recent exposure and that get tested after at least five days. According to the CDC, Day 0 is the first day of symptoms. This means that Day 1 is the first full day after the onset of symptoms.
After being quarantined for the appropriate amount of time, people who were exposed should continue to observe symptoms for at least 10 days after exposure. If symptoms occur, they should be isolated immediately and tested. After isolation ends, CDC recommends that people continue to wear a mask until day 10, or continue to isolate for a full 10 days if a mask cannot be worn. They also urged these people to avoid anyone with a weakened immune system or people most at risk of infection for the full 10 days.
According to the CDC, symptoms of COVID can appear between two and 14 days after a person is exposed to the virus. But the guidelines state that those who were exposed should watch for symptoms until at least 10 days after the last close contact with someone who had COVID. People who are very sick from COVID-19 (this means people who were hospitalized or needed intensive care or ventilation support) and people who have weakened immune systems may need to isolate at home longer. They may also require testing with a viral test to determine when they can be close to other people.
CDC recommends an isolation period of at least 10 and up to 20 days for people who have been very ill from COVID-19 and for people with weakened immune systems. Talk to your healthcare provider about when you can return to being close to other people. If you're not sure if your symptoms are severe or if you have a weakened immune system, talk to a healthcare provider for more guidance.
