Scientists Used Chinese Data
To predict the order of symptoms, researchers analyzed rates of symptom incidence collected by the World Health Organization for over 55,000 confirmed COVID-19 cases in China.
They also looked at a data set of almost 1,100 cases collected between December 2019 and January 2020 by the China Medical Treatment Expert Group for COVID-19 and provided by the National Health Commission of China.
To compare the order of COVID-19 symptoms to influenza, the researchers analyzed data from over 2,000 influenza cases in North America, Europe, and the Southern Hemisphere reported to health authorities between 1994 and 1998.
The order of the symptoms matter, said Joseph Larsen, lead study author and USC Dornsife doctoral candidate. Knowing that each illness progresses differently means that doctors can identify sooner whether someone likely has COVID-19, or another illness, which can help them make better treatment decisions.
According to the studys findings, this is the order of symptoms that people with COVID-19 can experience:
The study found that patients with seasonal flu more commonly developed a cough before the onset of fever, Dr. Robert Glatter, emergency physician at Lenox Hill Hospital in New York, told Healthline. In reality, this may be difficult to discern since the flu often begins abruptly with a triad of symptoms, including back pain, chills, along with a dry cough.
If I Get A Breakthrough Infection How Sick Could I Get
Even with delta, the chance of getting a case of COVID-19 that’s bad enough to send you to the hospital is still very rare.
If you’re vaccinated, the risk of being hospitalized is 10 times lower than if you weren’t vaccinated, according to the latest data from the CDC. Those who get severely and critically ill with a breakthrough case tend to be older in one study done before delta, the median age was 80 with underlying medical conditions, like cardiovascular disease.
When I was sick, one thing was in the back of my mind as I monitored my symptoms: Would I have problems catching my breath?
Thankfully, when you get exposed, the vaccine has already set you up with antibodies, a first line of defense, that will neutralize parts of the virus that attach to the mucosal surfaces of your upper respiratory tract, says Torriani at UCSD.
“That initial moment when our body is attacked by the virus, that can lead to some disease,” she says. It’s a bit of a race. The virus may cause you to get a cold, but, in most people, your immune system will “get its act together and thwart that infection from going down into your lungs,” says Wachter.
If you’re concerned, you can keep an eye on your oxygen levels with a pulse oximeter. That’s much more important than your temperature or symptoms, he says.

Vaccines And New Variants
The vaccines target the spike protein. If the structure of the spike protein mutates drastically, some experts fear the vaccine may not work as efficiently.
But the vaccine induces a broad immune response thatll likely be able to recognize and respond to most variants.
The studies of immunity of the vaccines to date are showing that even the mutations of the virus are affected by the vaccine-induced immunity, so we will not face the phenomena we see with the influenza vaccines requiring new vaccine formulations for different viral strains which emerge more popular each year, said Dr. David Mulligan, the section chief of transplantation surgery and immunology at Yale Medicine and professor of surgery at Yale School of Medicine.
The mRNA vaccines also activate B cells that have the ability to produce antibodies over 8 months after being vaccinated, Mulligan said.
This would suggest that, once vaccinated, people will have long-term immunity and not need a booster, Mulligan added.
Even if a vaccine isnt a 100 percent match to the circulating variants, it can still help prevent infection and disease, said Ilhem Messaoudi Powers, PhD, the director of the University of California, Irvines Center for Virus Research.
Look at the flu shot, for example. Even in the years where the flu shot isnt a strong match to the circulating strains, the vaccine still confers partial protection, according to Messaoudi Powers.
Important Ways To Slow The Spread Of Covid
If you are NOT yet fully vaccinated, prevent long-term complications by protecting yourself and others from COVID-19.
Although media articles have reported that some people with post-COVID conditions say their symptoms improved after being vaccinated, studies are needed to determine the effects of vaccination on post-COVID conditions.

Can You Have Coronavirus Without A Fever
Yes, you can be infected with the coronavirus and have a cough or other symptoms with no fever, or a very low-grade one, especially in the first few days. Keep in mind that it is also possible to have COVID-19 with minimal or even no symptoms at all. People infected with the coronavirus who have no symptoms can still spread COVID-19 to others.
What Symptoms Do People With Long
A few months ago, we thought that COVID-19 was just a respiratory disease characterised by a cough and high temperature.
But now we know that the virus can cause a vast range of symptoms, from cardiovascular problems to gastrointestinal distress. Many long-term COVID sufferers report a variety of these ‘atypical’ symptoms coming and going over time.
We spoke with Dr Rachel Pope, Senior Lecturer in European Prehistory at the University of Liverpool, who has been suffering from symptoms for 13 weeks.
âIt started like a cold or flu,â she says. “By week four, most of the people around me who also had it, including my daughter and my former partner, got better.”.
But although Rachel had improved during her fourth week, she got worse again in week 5 and her symptoms moved from her airways into her internal organs, resulting in heart problems that took her to A&E.
âThe first time they thought I was having a stroke, and the second time they thought it was a heart attack,â she says.
Experts have recently warned that COVID-19 may cause lasting damage to other internal organs, including the lungs, liver, brain, and kidney. This may explain why some people continue to experience symptoms long after the virus has been cleared from the body.â

Q: How Can A Virus Cause Smell And Taste Loss
One possibility is that people with upper respiratory infections often have congestion, drainage and other nasal symptoms that can block odors ability to reach the smell nerve, which sits at the top of the nasal cavity. But, we believe the primary cause, particularly for people with extended or permanent loss of smell function, is that the virus causes an inflammatory reaction inside the nose that can lead to a loss of the olfactory, or smell, neurons.
In some cases, this is permanent, but in other cases, the neurons can regenerate. Thats likely what determines which patients recover. In COVID-19, we believe smell loss is so prevalent because the receptors for COVID-19 that are expressed in human tissue are most commonly expressed in the nasal cavity and in the supporting cells of the olfactory tissue. These supporting cells surround the smell neurons and allow them to survive.
What Does The Cdc’s Definition Of Close Contacts Mean For Me
The CDC defines a close contact as someone who spends 15 minutes or more within six feet of a person with COVID-19;over a period of 24 hours.
Close contacts are at increased risk of infection. When a person tests positive for COVID-19, contact tracers may identify their close contacts and urge them to quarantine to prevent further spread. Based on the new definition, more people will now be considered close contacts.
Many factors can affect the chances that infection will spread from one person to another. These factors include whether or one or both people are wearing masks, whether the infected person is coughing or showing other symptoms, and whether the encounter occurred indoors or outdoors. Though the “15 minutes within six feet rule” is a helpful guideline, it’s always best to minimize close interactions with people who are not members of your household.
The CDC’s definition was influenced by a case described in the CDC’s;Morbidity and Mortality Weekly Report;in which a correctional officer in Vermont is believed to have been infected after being within six feet for 17;non-consecutive;minutes of six asymptomatic individuals, all of whom later tested positive for COVID-19.

The Most Concerning Symptom: Shortness Of Breath
Once symptoms appear, some early signs should be treated with more caution than others.;
“I would of course always ask about shortness of breath before anything, because that’s somebody who has to be immediately helped,” Megan Coffee, an infectious-disease clinician who analyzed the Wenzhou data, told Business Insider.
Patients who develop ARDS may need to be put on a ventilator in ICU. Coffee estimated that one in four hospitalized COVID-19 patients wind up on the ICU track. Those who are ultimately discharged, she added, should expect another month of rest, rehabilitation, and recovery.
But viewing coronavirus infections based on averages can hide the fact that the disease often doesn’t progress in a linear fashion.
“Courses can step by step worsen progressively. They can wax and wane, doing well one day, worse the next,” Coffee said. “An 80-year-old man with medical issues can do quite well. Sometimes a 40-year-old woman with no medical issues doesn’t.”
This story was originally published February 21, 2020. It has been updated over time with additional research findings.
Q: What Questions About These Covid
We plan to watch the recovery rate for these patients. We encourage people who have prolonged smell and taste dysfunction to be evaluated to help us understand if and when these symptoms resolve. There is also concern that COVID-19 and its ability to enter the olfactory tissue could be a conduit for infection in the brain. I think well learn more about that as we follow these patients over time.

Patients In The Hospital Seem To Get Better Before They Get Worse
A respiratory therapist told ProPublica last week that “patients will be on minimal support, on a little bit of oxygen, and then all of a sudden they go into complete respiratory arrest, shut down, and can’t breathe at all.”
This sudden decline is more likely among elderly people and those with preexisting health conditions, but the respiratory therapist said he had seen it happen among healthy people in their 40s.
Unlike people with pneumonia or acute respiratory distress syndrome, a disease where fluid builds up in the lungs, people with COVID-19 often don’t experience respiratory failure in the first few days of hospitalization, Gong said. She added that she had seen several COVID-19 patients with cardiac arrest, which might have to do with underlying conditions.
“But, again, it is sudden,” Gong said. “It’s not yet predictable to us as to who will get it and who will not.”
Gong advised doctors not to use chloroquine, an immunosuppressive drug designed to treat malaria, for COVID-19 patients. She said that while she understood that physicians may be desperate for a cure, the drug could harm these patients, as the medical establishment still doesn’t know exactly how it works on the illness and it could deprive people who need the drug of their medicine.
“I still feel like we haven’t seen the full extent,” an internal-medicine doctor told Business Insider last week. “It’s like leaning over the edge of a cliff.”
Everything You Need To Know About The Coronavirus
Right now, the Centers for Disease Control and Prevention says that people can stop isolating if theyve been fever-free for 72 hours, their other symptoms have improved, and its been at least seven days since they first felt sick. The limited information available about how patients recover seems to support those guidelines, says James Hudspeth, the COVID response inpatient floor lead at Boston Medical Center.
But patients like Harmanci are still facing conflicting advice, in part because theres still no clear data showing just how long people who get COVID-19 are contagious. There are a lot of questions left unanswered, says Hudspeth.
One study out of Germany, that hasnt been peer-reviewed, showed that people who had COVID-19 but werent hospitalized had high levels of the novel coronavirus in their respiratory tract early on in their illness. The levels dropped off after four or five days of symptoms, and by the tenth day after they got sick, there was hardly any virus left. A study of hospitalized patients in China, though, found that the virus was detectable for up to 20 days after symptoms started but levels also dropped off when the symptoms did.
There are a lot of questions left unanswered
Doctors still dont know how much of the virus is enough to infect someone else. But Hudspeth says they generally feel that if people have lower levels of the virus, the chances that theyre contagious is lower, as well.
‘weird As Hell: The Covid
Researchers keen to work out why some people are suffering from long tail form of the virus
In mid-March Paul Garner developed what he thought was a bit of a cough. A professor of infectious diseases, Garner was discussing the new coronavirus with David Nabarro, the UKs special envoy on the pandemic. At the end of the Zoom call, Nabarro advised Garner to go home immediately and to self-isolate. Garner did. He felt no more than a little bit off.
Days later, he found himself fighting a raging infection. Its one he likens to being abused by somebody or clubbed over the head with a cricket bat. The symptoms were weird as hell, he says. They included loss of smell, heaviness, malaise, tight chest and racing heart. At one point Garner thought he was about to die. He tried to Google fulminating myocarditis but was too unwell to navigate the screen.
Garner refers to himself wryly as a member of the Boris Johnson herd immunity group. This is the cluster of patients who contracted Covid-19 in the 12 days before the UK finally locked down. He assumed his illness would swiftly pass. Instead it went on and on a rollercoaster of ill health, extreme emotions and utter exhaustion, as he put it in a blog last week for the British Medical Journal.
He adds: We are the country that invented epidemiology. We havent produced any epidemiological studies other than the app. Its kind of embarrassing.
Mild Symptoms Of Covid
Because this particular coronavirus is so new it first appeared in late 2019 in Wuhan, China were still learning about it and the symptoms it causes. However, when mild symptoms occur, they can mimic the common cold and include:
- Low-grade fever
- Nasal congestion
- Mild, dry cough
- Mild body aches
There have also been reports of people testing positive for the virus without having any symptoms.
A joint World Health Organization-China mission of 25 infectious disease experts went to China in February. According to their report, 80 percent of known COVID-19 cases cause mild to moderate symptoms that dont require special treatment. So, if you have these mild symptoms, you can get better at home without a trip to your doctors office. Your immune system will do its job and fight the virus.;

Coronavirus Symptoms: Frequently Asked Questions
Do you know the symptoms of COVID-19? Knowing the warning signs can help you take the right steps if you or loved ones become sick. Lisa Maragakis, M.D., M.P.H., senior director of infection prevention, provides an update on what to look out for and when to get help.
Breakthrough Covid Infections Add Even More Chaos To School’s Start In 2021
I ended up in quarantine at my father’s house. Two rapid antigen tests came back negative, but I could tell I was starting to feel sick. After my second negative test, the nurse leveled with me. “Don’t hang your hat on this,” she said of the results. Sure enough, a few days later the results of a PCR test for the coronavirus confirmed what had become obvious by then.
It was a miserable five days. My legs and arms ached, my fever crept up to 103 and every few hours of sleep would leave my sheets drenched in sweat. I’d drop into bed exhausted after a quick trip down to the kitchen. To sum it up, I’d put my breakthrough case of COVID-19 right up there with my worst bouts of flu. Even after my fever cleared up, I spent the next few weeks feeling low.
Of course, I am very lucky. I didn’t go up against the virus with a naive immune system, like millions of Americans did until vaccines were widely available. And, in much of the world, vaccines are still a distant promise.
“You probably would have gotten much sicker if you had not been vaccinated,” Dr. Francesca Torriani, an infectious disease physician at the University of California, San Diego, explained to me recently.
As I shuffled around my room checking my fever, it was also reassuring to know that my chances of ending up in the hospital were very slim, even with the delta variant. And now, about a month later, I’ve made a full recovery.
