How long do symptoms of Omicron appear after exposure to the source?

In 2020, people in many countries are required to stay at home to avoid Covid-19 infection. Two years on, the world has changed and so has the variation.

Countries are trying to live with the Omicron variant that is a far cry from the common circulating SARS-CoV-2 virus in early 2020. Variants now cause less severe disease than in the past but are more contagious. .

In addition, the data revealed new variants that cause symptoms to manifest over a shorter period of time. When Alpha and Delta variants predominate, the World Health Organization (WHO) says, it usually takes two days to two weeks for symptoms to appear. With Omicron and its branch variants, the time period can be much shorter (3-5 days).

Dr Allison Arwady said: “What we are seeing is everything is being sped up. It will take less time to become infected and develop symptoms.”

What’s more, says Dr. Arwady, people generally “take less time to recover”. A person’s ability to contract the virus occurs within 5 days.

Scientists believe that a person is most contagious 1 to 2 days before symptoms develop and for 2 to 3 days after symptoms begin.

UK Health Secretary Sajid Javid said: “Recent analysis from the UK Health Security Service notes that the gap between infection and the infectivity of the Omicron variant may be shorter than that of the Omicron variant. Delta”.

Symptoms also vary as the period of infection. At the start of the pandemic, the most common symptoms of Covid-19 were a persistent cough, fever, and loss of smell/taste.

Today, the symptoms caused by Omicron closely resemble the common cold, including body aches, runny nose, headache, fatigue, and itchy throat.
