As infections of the Omicron variant of SARS-CoV-2 — the virus that causes COVID-19 — continue to spread around the world, there have been reports that symptoms, in some respects, are different... Omicron and its subvariant, BA.2 tend to cause milder disease than other variants. Particularly in vaccinated people, those symptoms don't last as long. It's important to know when you might start experiencing the symptoms of Omicron so that you can track backwards to understand the infection pathway. It can take a few days to a week for some of the symptoms to start emerging. You should also track if your symptoms start to escalate or diminish over time, to know what the role of your symptoms are. Symptoms of omicron and its subvariants are similar, doctors say. They're all still Covid, and they can still cause severe disease.
