Data from the ZOE Covid study predicted in December, 1,418 people a day would go on to experience symptoms for longer than 12 weeks. Omicron is thought to be much faster working than Delta or Alpha - so you will likely see symptoms sooner, around the two day mark. Several studies have found that the incubation period the time it takes to develop symptoms after being exposed is about three days. And doctors are finding many of these cases tend to look like an ordinary upper respiratory infection. Contagiousness. Far more Omicron symptoms have been identified than the official three listed by the NHS. Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. One study found that Omicron symptoms could last anywhere from a few days to a week.

Previous Covid variants were more likely to lead to a loss . Both California and Sacramento County are seeing record numbers of infections and testing is in great demand. Again, everyone is different and will experience their own early symptoms, but these seem to be among the group reported be most patients. Its possible that symptoms might be so mild people write it off as allergies, just a little case of the sniffles, or a headache due to some other reason, Laura Morris, MD, family physician and COVID-19 vaccine co-chair at University of Missouri, told Verywell. Severe casesSeverity varies by individual, depending on many factors, including vaccination status, age, overall health and socioeconomic factors. "With omicron there's at least a suggestion that you become infected and symptomatic within two or three days." said . That consistency, Xu says, suggests the reduction in severity is due, in part, to something inherent with omicron itself and not simply because of changes in vaccination status. Its causing symptoms that are much more like a regular cold, particularly in people whove been vaccinated, and fewer general systemic symptoms, such as nausea, muscle pains, diarrhoea and skin rashes.

In terms of transmissibility, we are seeing a really increased growth rate of Omicron over other variants of concern. The omicron subvariant of COVID-19, BA.5, became one of the dominant strains of the virus in the fall of 2022 in the U.S. At that time, it was the most easily spread strain to date and is able to evade immunity from COVID infection and vaccination. Dr. Arias has seen severe presentation of the disease particularly in high-risk patients, such as immunocompromised individuals, the elderly or someone with one or more comorbidities. Diarrhea.

How Delta presents differently to other COVID strains, Research suggests hospitalisation risk lower for Omicron. Scientists named this variant Omicron BA.2 to distinguish it from the original Omicron variant, BA.1. As with previous variants, the vast majority of people infected with omicron have a mix of symptoms that resolve relatively quickly and don't require hospital care. Omicron has a higher transmission rate and "you don't need four hoursto be exposed.". A shorter incubation period often means someone infected becomes contagious faster. We do know that it has what we call a growth advantage over Delta. It's also still not clear how much vaccines and prior infections are responsible for some of these early clinical impressions that omicron is causing a milder constellation of symptoms, says Dr. Daniel Griffin, who's chief of infectious diseases at ProHEALTH in New York and an instructor at Columbia University.

The recent rise in positive cases in the over-75s is worrying, but were hopeful that high levels of vaccination in older and more vulnerable groups will continue to translate to milder symptoms and few hospitalisations. Shortness of breath or difficulty breathing. Morris said symptoms indicative of pneumonia or respiratory failure, like shortness of breath, chest pain, cough tend to show up later, between day five and 10. Australia's isolation guidelines mean that people are expected to no longer be contagious if their symptoms have ceased and they have completed seven days of isolation from the date they were tested. "Omicron versus delta are really more similar than they are different.". And most of all, does this variant cause less severe disease than the variants that have come before it?

With the earlier variants, those were dry coughs. So which ones are best? Professor McLaws says there is alack of data around whether the Delta or Omicron variant is responsible for the rise in hospitalisations. Yes, but: It's important to remember that having "mild" COVID-19 symptoms doesn't mean your . "So this is really something that's different between omicron and delta," Xu says. However, despite all these stages, you may miss them all together and just test positive when doing the lateral flows we should all be taking regularly.

Here are answers to some of our audience's most searched-for questions about COVID-19 exposure. The new coronavirus mutation has spread like wildfire across the UK, in a little over a month cases have spiralled from single digits to a quarter of a million. (with symptoms, . A preprint study of more than 60,000 people in the United Kingdom indicates that people who are infected with Omicron have symptoms for about two days fewer than those infected with Delta, on average. And although its not yet clear whether we will be facing an overwhelming wave of hospitalisations from the disease, its important to remember that while Omicron and Delta may feel like a cold to many of us, it can still kill or cause long-term symptoms that disrupt daily life, especially for people who have not been vaccinated or are immunocompromised.
