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.
Could I Get Long Covid After A Breakthrough Infection
While there’s not a lot of data yet, research does show that breakthrough infections can lead to the kind of persistent symptoms that characterize;long covid, including brain fog, fatigue and headaches. “Hopefully that number is low. Hopefully it doesn’t last as long and it’s not as severe, but it’s just too early to know these things,” Topol said.
Recent research from the United Kingdom;suggests that vaccinated people;are about 50% less likely to develop long covid than those who are unvaccinated.

Is It Time For A Reality Check About What The Vaccines Can And Cant Do
The vaccines arent a force field that wards off all things covid. They were given the green light because they greatly lower your chance of getting seriously ill or dying.
But it was easy for me and Im not the only one to grab onto the idea that, after so many months of trying not to get covid, the vaccine was, more or less, the finish line. And that made getting sick from the virus unnerving.
After all, there were reassuring findings;earlier this year;that the vaccine was remarkably good at stopping any infection, even mild ones.
There was so much initial euphoria about how well these vaccines work, said Dr.;Jeff Duchin, an infectious-disease physician and the public health officer for Seattle and King County. I think we in the public health community, in the medical community facilitated the impression that these vaccines are bulletproof.
Its hard to keep adjusting your risk calculations. So if youd hoped to avoid getting sick at all, even slightly, it may be time for a reset, Duchin said. This isnt to be alarmist but a reminder to clear away expectations that covid is out of your life, and stay vigilant about commonsense precautions.
Is A Lost Sense Of Smell A Symptom Of Covid
A lost sense of smell, known medically as anosmia, is a common symptom of COVID-19. This is not surprising, because viral infections are a leading cause of loss of sense of smell, and COVID-19 is a caused by a virus. Still, loss of smell with COVID-19 appears to occur much more often compared to other viral infections. So, this symptom may help doctors identify people who do not have other symptoms, but who might be infected with the COVID-19 virus and who might be unwittingly infecting others.
In addition to COVID-19, loss of smell can also result from allergies as well as other viruses, including rhinoviruses that cause the common cold. So anosmia alone does not mean you have COVID-19.
Tell your doctor right away if you find yourself newly unable to smell. He or she may prompt you to get tested and to self-isolate.
Loss of smell can last for several months after COVID infection, but in nearly all cases, it returns within one year. A study of nearly 100 COVID patients who lost their sense of smell found that 86% recovered their sense of smell by six months after infection, and 96% recovered their sense of smell within 12 months after infection.

Coronavirus: What Are Asymptomatic And Mild Covid
As the coronavirus pandemic continues, we’re learning more about how different groups experience COVID-19. Everyone is talking about mild, moderate and severe cases, and critical cases. What does this mean?

There are, as yet, no clear guides for patients to tell them what doctors mean by mild, moderate or severe COVID-19. Some guidance on classifying illness is appearing in research papers and epidemiological reports, but it’s not very specific. For example, the broad definition of moderate disease seems to be that it’s worse than mild disease but not severe.

Q: What Is Known About The Covid
A recent study based on retrospective data showed that patients who had normal smell function in COVID-19 appeared to have a worse disease course and were more likely to be hospitalized and placed on a ventilator. This suggests patients who experience smell dysfunction may have a milder infection or disease. The data we have so far also suggest that in a substantial percentage of the COVID-19-infected population, smell loss can be one of the first or only signs of disease. It may precede symptoms that are more commonly associated with COVID-19, such as cough and fever. It has even been proposed that smell and taste loss could be a screening tool since these symptoms appear so early.
Debilitating Fever Isolation Fear Guilt: My Mild Covid
I’m sharing my story because I had difficulty finding information on what I should expect once I’d learned I was positive. Yes, I found lists of symptoms, but no real example of what the experience would be like. I’ll skip the drama and tell you that I lived. I was one of the fortunate 80% of people infected by the virus who had a “mild” case. But what does that mean?
It began with a slight tickle in my throat on July 9. Having suffered most of my life from allergies, this wasn’t a big deal. Even when I felt slightly worse the next day, no flags were raised. But on July 11 around noon, I knew something was wrong. I had a fever of 101.5. I immediately quarantined myself to an extra bedroom and arranged a Houston Methodist Virtual Urgent Care visit. The physician I visited with ordered a COVID-19 test for me for the following Monday.
Immediately after learning I was positive, I began trying to read as much as I could about what I should expect. This virus is a true monster, and, as far as I can tell, doesn’t affect anyone the same way.
So what was it like? I had a constant fever that wouldn’t break, even with Tylenol. This made me uncomfortable 100% of the time. I was either cold and shivering or burning hot and sweaty. A few nights my chills were so severe and my teeth chattered so hard, my skull ached. About a week in I began to wonder if I’d ever feel healthy again as I could not remember what it felt like to not have a fever.

It Lasted 10 To 16 Days
Elizabeth Schneider caught coronavirus after attending a house party in Seattle. Forty per cent of the people who attended the party contracted the illness.
The 37-year-old described her experience on Instagram last week, describing her symptoms as: Headache, fever, severe body aches and joint pain, and severe fatigue.
I had a fever that spiked the first night to 103 degrees , which eventually came down to 100 , she said.
I felt nauseous. Once the fever is gone, some were left with nasal congestion, sore throat. The total duration of the illness was 10 to 16 days.

Asymptomatic Infections And New Variants
Some people who contract the new coronavirus may have no symptoms at all. But people with asymptomatic infections can still spread the virus to others without knowing they have an infection.
Because weve never seen this virus before, theres no immunity in the population like we have with the flu, according to Murphy. It can spread readily from person to person, more quickly than other respiratory infections like the flu.
How someones body reacts to the virus comes down to what Murphy calls the host-pathogen interaction: You have the pathogen , and then you have the host, or how an individuals immune system gears up and responds.
Does the host mount a good immunologic response that can get rid of the virus, does it not mount a good enough response so the virus is more lethal, or does it mount too much of an immunologic response and you have as much trouble from the immunologic response as you do from the virus? Murphy explained.
While vaccines are being rolled out it will take months before enough people are vaccinated that it drives down the spread of the virus. In the meantime theres a low-tech solution to stopping the spread of the virus: face masks.
Face coverings like masks are another essential tool that can blunt the spread of the disease. Research suggests masks effectively prevent transmission.
Around 80 percent of people who get COVID-19 will likely experience mild symptoms.
How To Care For Mild Symptoms Of Covid
If you think you have COVID-19, the first thing to do is to isolate yourself from the public and anyone else who is not sick in your household. Dont leave your home until 10 days have passed since your first symptoms, and you are free of fever for 24 hours without using fever-reducing medications, and your symptoms are improving.
The next thing to do is to call your healthcare provider. You can also see an online doctor if you have concerns about your symptoms and want to know more about what to do next.
Mild symptoms, like cough, body aches, and fever can be treated with over-the-counter cold and flu medications, or simple . is probably safe if acetaminophen isnt enough. Get plenty of rest, nutrition, and hydration.;
Can I Spread It To Others And Do I Need To Isolate
Unfortunately, you still have covid and need to act like it.
Even though my first two tests were negative, I started wearing a mask at my house and keeping my distance from my vaccinated family members. I’m glad I did: No one else got sick.
The delta variant is more than twice as contagious as the original strain of the virus and can build up quickly in your upper respiratory tract, as was shown in;a cluster of breakthrough infections linked to Provincetown, Massachusetts, over the summer.
“Even in fully vaccinated, asymptomatic individuals, they can have enough virus to transmit it,” said;Dr. Robert Darnell, a physician-scientist at The Rockefeller University.
The science isn’t settled about just how likely vaccinated people are to spread the virus, and it does appear that;the amount of virus in the nose decreases;faster in people who are vaccinated.
Still, wearing masks and staying isolated from others if you test positive or have symptoms is absolutely critical, Darnell said.
What Is A ‘moderate To Severe’ Case Of Covid
The primary reason people with COVID-19 end up requiring hospitalization is due to respiratory problems, namely low oxygen levels, says Lauren Ferrante, MD, MHS, a Yale Medicine pulmonologist and critical care specialist.
But she says that experiencing the need for oxygen doesnt mean youll become critically ill. Most COVID-19 patients don’t need ventilators, and most people don’t end up in the ICU, she notes. Rather, most can be taken care of on the general floor and given oxygen that flows through a tube into their nostrils. These patients may have respiratory symptoms, particularly with exertion, but overall do well with oxygen. They are alert and often talking to their families on FaceTime.
Often, the patients who become dangerously ill have other risk factors, including obesity, diabetes, heart or lung disease, cancer, other immune problems, or are over 65, Dr. Sofair says.
These patients may end up in the ICU, requiring higher amounts of oxygen and possibly a ventilator. The sickest may end up with other problems too, notes Dr. Ferrante. When patients are critically ill, their other organs may start to shut down, she says.

How Will I Feel If I Have Covid
The coronavirus affects people differently. Some people have no symptoms at all and may not even know they are ill, even though they can transmit the coronavirus to others.
If you have any of the following symptoms, call your doctor. He or she will say whether you need a test and recommend what you should do.
- Shortness of breath or difficulty breathing
- Muscle or body aches
- New loss of taste or smell
- Nausea or vomiting
- Congestion or runny nose
In some people, COVID-19 can start out mild and become serious quickly. If you experience shortness of breath or difficulty breathing, call 911 immediately or go to an emergency department.
Most people with a mild case of COVID-19 can rest at home and self-isolate.
Why You Need To Call First
If youre wondering why doctors are asking patients to call before going to any facility for care, Dr. Arnold says its because it gives the staff time to prepare for your arrival. It also gives your doctor a chance to see if you can get the care you need through an e-visit or a video visit instead of coming into the office.
In some cases, we can evaluate your symptoms over the phone or arrange an e-visit, she says. Calling ahead is good for everyone it protects you, our staff and our patients who need care for other reasons.
Dr. Arnold adds, We want everyone to know that its still safe to come to your primary care office, but please call first so we can give you the best care possible.
