| COVID's incubation period has changed with the extra-contagious BA.4 and BA.5 omicron subvariants, Chicago's top doctor said, but what does that mean for how long you are contagious? During a Facebook Live last month, Chicago Department of Public Health Commissioner Dr. Allison Arwady reported that recent studies have shown the incubation period for COVID has dropped to three days with recent variants. "So if you go back to like alpha variant, beta, delta – early on, it was about a five-day incubation period on average. So, if you were exposed to COVID, on average we were seeing people take about five days for someone to end up testing positive – and remember that went from four to five, out to 10, out to 14," she said. "The reason … we only use 10 days now, it is because that timing has shortened. And so, more recently with BA.4, BA.5, that's all the way down to about three days now. So on average, people are testing positive about 3 days after, but you can have someone positive up to 10 days." |
