"Omicron can present in a myriad of different ways," he says. The omicron variant of the coronavirus has surged in the U.K. and is now dominant in the U.S. as well.

With researchers finding that "the risk of reinfection with the Omicron variant is 5.4 times greater than that of the Delta variant.". What's more, America's Centre for Disease Control and Prevention (CDC) (opens in new tab) have stated that those who have had Covid previously have a "low risk of subsequent infection" for at least six months.

"Therefore, if you have these symptoms, Id encourage you to use lateral flow tests for a couple of days.". (Thankfully, most PCR tests do seem to be detecting Omicron well.)

"A runny nose and headache are symptoms of many infections, but may also be the first symptoms and only symptoms of Covid," explains Professor Irene Petersen, an epidemiology and health professor at University College London (opens in new tab). "That's why the spread is occurring at a much faster pace," said Dr. Anita Gupta, an anesthesiologist and critical care physician at the Johns Hopkins School of Medicine. "Just like previous variants, omicron is hospitalizing people and it is killing people.". Shorter incubation periods generally lead to more infections happening in less time, because people are becoming more contagious sooner, making onward transmission harder to prevent. The UK Health Security Agency have reported a total of 75 Omicron related deaths in the United Kingdom.

Households with children in school and healthcare workers are amongst the two groups most likely for this to occur.
