How Do You Know When Septic Is Full
The dizzying speed of omicron's spread has left Americans questioning much of what they know nearly Covid-19.
Though much remains uncertain, experts are beginning to empathise more than most the variant and how it affects people who are vaccinated, unvaccinated or who have had a Covid infection. For example, people who are exposed to omicron appear to get sick faster and may have symptoms that are different than those of other variants.
What are the symptoms of omicron?
Early evidence suggests that for near people, at least those who are up to date on their Covid vaccines, omicron appears to crusade milder illness that can resemble the common common cold, some other form of the coronavirus.

Dr. Katherine Poehling, an communicable diseases specialist and vaccinologist at Atrium Health Wake Woods Baptist in North Carolina, said that these appear to exist the prominent symptoms from omicron:
- Cough
- Fatigue or tiredness
- Congestion and runny olfactory organ
- Sore pharynx
- Headache
"We're seeing a lot of sore throat, runny nose, fatigue and mild headache," said Dr. Rahul Sharma, the emergency medico-in-chief at the NewYork-Presbyterian/Weill Cornell Medical Center.
Unlike in previous variants, the loss of taste and smell seems to be uncommon, doctors say.
Only Poehling, who is too a fellow member of the Advisory Committee on Immunization Practices, which helps guide the Centers for Disease Control and Prevention'due south decisions on vaccines, and others stress that those symptoms are based on early reports of omicron cases, not scientific studies.
"Anecdotal reports represent just one person," said Dr. Bruce Y. Lee, a professor of health policy and management at the Urban center University of New York School of Public Health. "We have to take them with a grain of salt."
What's more, they may only reflect certain segments of the population: young and otherwise healthy, equally well as those who are fully vaccinated.
"It is articulate that if you're vaccinated, peculiarly if you've had a booster, omicron tends to produce milder infections," said Dr. William Schaffner, an infectious disease adept at the Vanderbilt University Medical Center in Nashville, Tennessee.
"What we oasis't seen still is a substantial body of data about what omicron will do in unvaccinated people," he added.
Indeed, at to the lowest degree 1 person who was not vaccinated is reported to have died of omicron. Officials in Houston announced in December that the unvaccinated man in his 50s succumbed to the virus.
For people who have been vaccinated, just have not had a booster, typical symptoms include more coughing, more than fever and more fatigue than those who accept received an actress dose, said Dr. Craig Spencer, manager of global health in emergency medicine at New York-Presbyterian/Columbia University Medical Middle.
Does omicron cause less severe illness?
At that place is also emerging evidence that omicron tends non to burrow deep into the lungs as much as previous variants. A study, which was posted online by the Academy of Hong Kong and not yet peer-reviewed, found that while omicron is less astringent in the lungs, information technology can replicate faster higher up in the respiratory tract.
In this way, omicron may human action more than like bronchitis than pneumonia, said Dr. Hugh Cassiere, manager of critical care services for Sandra Atlas Bass Center Infirmary at the North Shore University Hospital, on Long Island, New York.
"Commonly patients with astute bronchitis tend not to be short of breath. They tend to coughing and produce sputum," he said. "Patients with pneumonia tend to exist brusk of jiff and feel more fatigued than bronchitis in general."
A small study from the CDC plant that people who had Covid and are afterwards reinfected with omicron may feel fewer symptoms than they did during their initial bout with the virus.
Still, information technology's near impossible for people to rely on symptoms to self-diagnose an disease. In addition to omicron, the delta variant continues to circulate, along with increasing cases of the flu.
For these reasons, doctors urge people who have any common cold symptoms or flulike symptoms to get tested.
How quickly practice omicron symptoms start?
According to early on data, the time information technology takes for an infected person to develop symptoms after an exposure may be shorter for omicron than for previous variants — from a full week down to every bit little as three days or less.
While much more research is needed, it makes scientific sense that a highly contagious virus similar the omicron variant would have a shorter incubation period. Its goal, after all, is to infect as many people as possible, every bit speedily as possible.
"That'southward why the spread is occurring at a much faster stride," said Dr. Anita Gupta, an anesthesiologist and disquisitional intendance physician at the Johns Hopkins School of Medicine. She added that it's possible the incubation menstruum could be shorter or longer depending on a number of variables, including historic period, underlying health problems and vaccination status. "At that place is no difficult and fast rule here."
How long practice symptoms last?
Symptoms appear to final three to v days for virtually patients, said Sharma.
"A lot of these patients are not having the symptoms for the 10 to 12 days that I saw when there were no vaccinations," he said. He noted that, in general, symptoms appear to exist shorter and milder in the vaccinated compared to the unvaccinated.
For the vaccinated, emergency room or infirmary stays are also typically shorter.
"What I can tell yous is that patients that are unvaccinated are definitely our sicker patients," Sharma said. "Those are the patients that are more than likely to go to the ICU. Those are the patients that are more than probable to exist admitted to the infirmary."
Dr. Ryan Maves, an infectious diseases and disquisitional care physician at the Wake Woods School of Medicine in North Carolina, agreed, saying the overwhelming majority of Covid patients he sees in the ICU are unvaccinated.
When should I get tested for Covid?
Given the potential for a shorter incubation period, Vanderbilt's Schaffner brash that anyone who has been in contact with an infected individual get tested about 72 hours post-obit the exposure.
"If you've been exposed and now you're asking yourself, 'When should I become tested?' I think you would best expect at to the lowest degree 3 days to see if you've turned positive," he said.
For the millions of people without whatever known Covid exposure, simply who are getting together with friends and family, Schaffner said, it would exist prudent to get a rapid examination the day of the gathering.
Dr. Anthony Fauci, primary medical adviser to President Joe Biden, agreed.
"By all means, become the extra step, go the actress mile to get tested" to alleviate any concerns about gatherings, he said on NBC's "TODAY" show final month.
Could omicron pb to long Covid?
Though much remains unknown about omicron, experts say the variant could lead to long Covid, even with a mild instance.
Patients with long-term symptoms can experience crushing fatigue, irregular heart rhythms and other issues months after their initial Covid infection. This occurred during the first wave of the pandemic, and has continued to pb to long Covid problems through the delta wave.
"We should assume that this variant can practise the same thing that previous variants have until proven otherwise," Lee, of CUNY, said.
Previous inquiry, still, suggests that vaccination can greatly reduce the risk for long Covid.
How worried should I be near omicron?
The omicron variant accounts for about 95 percent of U.South. samples and the delta variant makes up the remainder, according to contempo CDC projections.
Since omicron has hit about every area of the U.Due south., "the question is, how much disease will it crusade?" said Dr. Michael Saag, an communicable diseases proficient and associate dean for global health at the Academy of Alabama at Birmingham.
Experts continue to urge people to get vaccinated and get a booster shot to reduce the risk of astringent illness.
