How Did I Get Sick Again Within Days
The boundless speed of omicron's spread has left Americans questioning much of what they know about Covid-19.
Though much remains uncertain, experts are first to sympathize more than nigh the variant and how it affects people who are vaccinated, unvaccinated or who take had a Covid infection. For instance, people who are exposed to omicron appear to get sick faster and may take symptoms that are different than those of other variants.
What are the symptoms of omicron?
Early evidence suggests that for most people, at least those who are upward to date on their Covid vaccines, omicron appears to cause milder illness that can resemble the common cold, some other form of the coronavirus.

Dr. Katherine Poehling, an communicable diseases specialist and vaccinologist at Atrium Health Wake Forest Baptist in Northward Carolina, said that these announced to exist the prominent symptoms from omicron:
- Cough
- Fatigue or tiredness
- Congestion and runny olfactory organ
- Sore throat
- Headache
"Nosotros're seeing a lot of sore throat, runny nose, fatigue and mild headache," said Dr. Rahul Sharma, the emergency physician-in-master at the NewYork-Presbyterian/Weill Cornell Medical Center.
Unlike in previous variants, the loss of taste and smell seems to be uncommon, doctors say.
Just Poehling, who is too a member of the Advisory Committee on Immunization Practices, which helps guide the Centers for Disease Control and Prevention'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 Metropolis University of New York School of Public Health. "Nosotros have to take them with a grain of salt."
What's more than, they may only reverberate sure segments of the population: immature and otherwise good for you, as well as those who are fully vaccinated.
"It is clear that if you're vaccinated, particularly if you've had a booster, omicron tends to produce milder infections," said Dr. William Schaffner, an infectious disease expert at the Vanderbilt Academy Medical Center in Nashville, Tennessee.
"What we haven't seen yet is a substantial body of data about what omicron will do in unvaccinated people," he added.
Indeed, at least i person who was non vaccinated is reported to have died of omicron. Officials in Houston announced in December that the unvaccinated homo in his 50s succumbed to the virus.
For people who accept been vaccinated, but have not had a booster, typical symptoms include more cough, more fever and more fatigue than those who have received an actress dose, said Dr. Craig Spencer, director of global health in emergency medicine at New York-Presbyterian/Columbia University Medical Center.
Does omicron cause less severe illness?
There is also emerging evidence that omicron tends not to burrow deep into the lungs as much as previous variants. A study, which was posted online past the Academy of Hong Kong and non however peer-reviewed, found that while omicron is less severe in the lungs, it can replicate faster college upward in the respiratory tract.
In this way, omicron may act more like bronchitis than pneumonia, said Dr. Hugh Cassiere, managing director of critical care services for Sandra Atlas Bass Heart Infirmary at the Due north Shore University Hospital, on Long Island, New York.
"Unremarkably patients with acute bronchitis tend non to be brusk of jiff. They tend to cough and produce sputum," he said. "Patients with pneumonia tend to exist short of breath and feel more fatigued than bronchitis in general."
A small-scale study from the CDC found that people who had Covid and are later reinfected with omicron may experience fewer symptoms than they did during their initial tour with the virus.
Notwithstanding, it's virtually impossible for people to rely on symptoms to cocky-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 accept whatsoever cold symptoms or flulike symptoms to get tested.
How quickly exercise omicron symptoms outset?
Co-ordinate to early data, the fourth dimension information technology takes for an infected person to develop symptoms after an exposure may be shorter for omicron than for previous variants — from a total calendar week down to as little as 3 days or less.
While much more enquiry is needed, information technology makes scientific sense that a highly contagious virus like the omicron variant would have a shorter incubation period. Its goal, after all, is to infect equally many people as possible, as quickly as possible.
"That's why the spread is occurring at a much faster pace," said Dr. Anita Gupta, an anesthesiologist and critical intendance md at the Johns Hopkins Schoolhouse of Medicine. She added that it's possible the incubation period could exist shorter or longer depending on a number of variables, including historic period, underlying health problems and vaccination status. "There is no hard and fast rule here."
How long do symptoms last?
Symptoms appear to concluding three to five days for most 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 be shorter and milder in the vaccinated compared to the unvaccinated.
For the vaccinated, emergency room or hospital stays are likewise typically shorter.
"What I can tell you is that patients that are unvaccinated are definitely our sicker patients," Sharma said. "Those are the patients that are more likely to go to the ICU. Those are the patients that are more likely to exist admitted to the hospital."
Dr. Ryan Maves, an infectious diseases and critical care doc at the Wake Forest School of Medicine in North Carolina, agreed, maxim 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 advised that anyone who has been in contact with an infected individual go tested virtually 72 hours following the exposure.
"If you've been exposed and at present y'all're asking yourself, 'When should I get tested?' I recollect you would best wait at to the lowest degree 3 days to see if you lot've turned positive," he said.
For the millions of people without whatever known Covid exposure, just who are getting together with friends and family, Schaffner said, it would be prudent to get a rapid test the day of the gathering.
Dr. Anthony Fauci, chief medical adviser to President Joe Biden, agreed.
"By all means, go the actress step, go the extra mile to go tested" to alleviate any concerns about gatherings, he said on NBC'due south "TODAY" bear witness last calendar month.
Could omicron lead to long Covid?
Though much remains unknown nearly omicron, experts say the variant could pb to long Covid, even with a mild instance.
Patients with long-term symptoms can feel crushing fatigue, irregular heart rhythms and other issues months after their initial Covid infection. This occurred during the first moving ridge of the pandemic, and has continued to lead to long Covid issues through the delta wave.
"We should presume that this variant can do the same thing that previous variants have until proven otherwise," Lee, of CUNY, said.
Previous research, however, suggests that vaccination tin profoundly reduce the run a risk for long Covid.
How worried should I be nigh omicron?
The omicron variant accounts for about 95 percent of U.S. samples and the delta variant makes up the rest, according to recent CDC projections.
Since omicron has striking almost every area of the U.S., "the question is, how much disease will it crusade?" said Dr. Michael Saag, an infectious disease proficient and acquaintance dean for global wellness at the University of Alabama at Birmingham.
Experts continue to urge people to get vaccinated and go a booster shot to reduce the adventure of astringent affliction.
