How Long Do Covid Symptoms Last On Average

Why Do Some People Get Very Sick From Covid

Long Covid: When coronavirus symptoms don’t go away | DW News

One of the most perplexing aspects of coronavirus is why it strikes people so differently. Why do some people sail through without a symptom, while others even some who are otherwise healthy and relatively young get extremely sick or even die? It may have to do with interferons.

New research suggests that up to 14% of people who develop severe COVID-19 have an inadequate interferon response. In some people, this happens because their own antibodies mistakenly attack and neutralize their interferons. Others have a genetic mutation that prevents their body from producing enough of a certain type of interferon.

Interferons are an important component of innate immunity, the quick, nonspecific immune defense the body mounts within minutes of infection to rid the body of invaders. Interferons help protect the body in a number of ways: they signal nearby cells to guard themselves against invasion they signal infected cells to die and they activate the adaptive immune system to mount a specific, long-term antibody response. An inadequate interferon response could help explain why some people especially some young people without underlying conditions get so much sicker than others their age.

When Do You Stop Being Contagious

Generally a person is officially in the clear and can be around others if they meet these criteria:

  • 10 days have passed since symptoms first appeared
  • 24 hours have passed with no fever
  • Other symptoms of COVID-19 are also improving or are gone

Being completely cleared wouldnt happen any sooner than 14 days, though, since the virus incubation period is two weeks. That is why you are required to quarantine for a full two weeks in order to prevent the spread of COVID-19.

Symptoms Spread And Other Essential Information About The Coronavirus And Covid

As we continue to learn more about coronavirus and COVID-19, it can help to reacquaint yourself with some basic information. For example, understanding how the virus spreads reinforces the importance of prevention measures. Knowing how COVID has impacted people of all ages may reinforce the need for everyone to adopt health-promoting behaviors. And reviewing the common symptoms of COVID-19 can help you know if it’s time to self-isolate.

What Is Long Covid

Long Covid is a term that is used to describe those who have recovered from a coronavirus infection, but are still experiencing some lasting effects, or the usual symptoms have lasted far longer than normally expected.

An estimated 10 per cent of people remain unwell beyond the usual time period, while a smaller proportion can experience symptoms for months, according to a study by Kings College.

The study found that some 250,000 people in the UK alone are thought to suffer symptoms for 30 days or more.

In many cases, people who suffered with long-lasting effects of the virus were fit, active and healthy.

The long-term symptoms that some people experience often vary widely and encompass both physical and neurological effects, with these lasting into weeks and even months in some cases.

Whats The Recovery Time For Coronavirus

Coronavirus: Long COVID could last at least seven weeks

Early research suggested that it could take 2 weeks for your body to get over a mild illness, or up to 6 weeks for severe or critical cases. Newer data show that recovery varies for different people, depending on things like your age and overall health. Fatigue, headache, and trouble breathing were the symptoms most likely to linger.

CDC guidelines say that if youve been sick, you should isolate yourself at home until all of these things are true:

  • You havent had a fever for 24 hours without using a fever-reducing medicine.
  • Your symptoms are better, though they might not be totally gone.
  • Its been at least 10 days since your symptoms started.

How Long Someone Can Spread The Virus

Similarities:

For both COVID-19 and flu, its possible to spread the virus for at least 1 day before experiencing any symptoms.

Differences:

If a person has COVID-19, they could be contagious for a longer time than if they had flu.

Most people with flu are contagious for about 1 day before they show symptoms.

Older children and adults with flu appear to be most contagious during the initial 3-4 days of their illness but many people remain contagious for about 7 days.

Infants and people with weakened immune systems can be contagious for even longer.

COVID-19

How long someone can spread the virus that causes COVID-19 is still under investigation.

Its possible for people to spread the virus for about 2 days before experiencing signs or symptoms and remain contagious for at least 10 days after signs or symptoms first appeared. If someone is asymptomatic or their symptoms go away, its possible to remain contagious for at least 10 days after testing positive for COVID-19. People who are hospitalized with severe disease and people with weakened immune systems can be contagious for 20 days or longer.

How Long Should I Quarantine After Ive Been Exposed To The Coronavirus

The CDC says that if you might have come into contact with the virus and have no symptoms, you should self-monitor. This means watching for signs such as fever, cough, and shortness of breath. Stay out of crowded places, keep at least 6 feet away from other people, and wear a cloth face mask when you have to go out.

Continued

If you traveled recently or know that you came into contact with someone who has COVID-19, you should self-quarantine. Stay home for 14 days. Its very rare for symptoms to show up after that much time. Check your temperature twice a day, and watch for other symptoms. Stay away from other people, especially those who are at high risk of serious illness because of their age or another medical condition.

If 14 days of isolation creates a hardship, the CDC advises you may be able to leave quarantine:

  • After day 10 without testing
  • After day 7 after receiving a negative test result

Still, after you leave quarantine, you should continue to monitor yourself for any symptoms.

Mild Vs Moderate Vs Severe Symptoms

COVID-19 severity is often divided into categories like mild, moderate, and severe. But what do these terms actually mean?

According to the COVID-19 treatment guidelines published by the National Institutes of Health , theyre defined as:

Research has found that about 81 percent of people with COVID-19 have a mild or moderate illness. According to the Centers for Disease Control and Prevention , most people with mild to moderate COVID-19 can recover at home.

Even if you have mild or moderate COVID-19, its still important to continue to monitor your symptoms as you recover. Even if you only have mild symptoms, its possible that they may begin to worsen, leading to more serious illness.

One potential symptom of COVID-19 is loss of smell or taste. An of 24 studies estimated a prevalence of 41 percent and 38.2 percent for loss of smell and taste, respectively.

Loss of smell and taste is also associated with mild COVID-19. A evaluated this symptom in 1,363 people with COVID-19.

Researchers observed loss of smell and taste in 85.9 percent of people with mild illness compared to 4.5 to 6.9 percent of people with moderate to severe illness. This symptom disappeared in 95 percent of individuals within 6 months.

I felt a little congested, but nothing more than allergies could cause. Then I realized one afternoon I could no longer smell my coffee, so I got tested. The rapid test came back positive.

How Long Does Fever Last With Covid

How long does the coronavirus stay on certain surfaces?

COVID-19 symptoms, including fever, vary from person to person. Fever can be one of the first signs of COVID-19, or fever can appear later during the illness. Some people dont have fever at all. It can be persistent or come and go for a few days or even weeks. That is why it is important to be fever-free for at least 24 hours before stopping isolation.

What If I Have Only Mild Symptoms

Most people who get Covid-19 will develop only the main symptoms – a cough or fever. But they could experience body aches, fatigue, sore throat and headache.

The cough is initially dry, but some people will eventually start coughing up mucus containing dead lung cells killed by the virus.

These symptoms are treated with bed rest, plenty of fluids and pain relief such as paracetamol.

People with mild symptoms should make a good and speedy recovery.

The fever should settle in less than a week, although the cough may linger. A World Health Organization analysis of Chinese data says it takes two weeks on average to recover.

As the coronavirus epidemic continues in the US, you might be wondering just how long you’ll be sick if you do contract COVID-19. Every case is different, but after months of scientific study and data collection, experts have a fairly good idea. Here are the symptoms you’ll be dealing with, when they’ll likely strike, and how long it will take until you’re fully recovered and can safely emerge from self-isolation.

What Are The Symptoms Of Covid

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common ones include fever, body ache, dry cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of smell. In some people, COVID-19 causes more severe symptoms like high fever, severe cough, and shortness of breath, which often indicates pneumonia.

People with COVID-19 can also experience neurological symptoms, gastrointestinal symptoms, or both. These may occur with or without respiratory symptoms.

For example, COVID-19 affects brain function in some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, inability to taste, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.

In addition, some people have gastrointestinal symptoms, such as loss of appetite, nausea, vomiting, diarrhea, and abdominal pain or discomfort associated with COVID-19. The virus that causes COVID-19 has also been detected in stool, which reinforces the importance of hand washing after every visit to the bathroom and regularly disinfecting bathroom fixtures.

When Is It Safe To Discontinue Isolation

What Recovery From COVID

Once you have been diagnosed with coronavirus, you will likely have to self-isolate for some period of time, at least 14 days. While the CDC no longer recommends a negative COVID-19 test before returning to the public, here are their guidelines and criteria for discontinuing isolation for people who have had symptoms and are not in healthcare settings:

  • It has been over 10 days since your symptoms first started.
  • You have been without a fever for over 24 hours without needing to use a fever-reducing medication.
  • Any other symptoms have improved.

If you have tested positive for COVID-19 but did not exhibit any symptoms, you can typically discontinue your isolation 10 days after first receiving your positive test results√Ębut be sure to consult with your healthcare provider first.

Also, even after you return to the public, make sure you still take the proper precautions to prevent the spread of the virus. While you may not be contagious, more research is necessary to determine the potential for reinfection. Even if you have antibodies in your system, they may not protect you from another coronavirus infection. Maintain social distancing, wear a mask, and regularly wash your hands.

Deltas Rise Is Fuelled By Rampant Spread From People Who Feel Fine

    People infected with the Delta variant of SARS-CoV-2 are more likely to spread the virus before developing symptoms than are people infected with earlier versions, suggests a detailed analysis of an outbreak in Guangdong, China.

    It is just tougher to stop, says Benjamin Cowling, an epidemiologist at the University of Hong Kong and a co-author of the study, which was posted on a preprint server on 13 August.

    Cowling and his colleagues analysed exhaustive test data from 101 people in Guangdong who were infected with Delta between May and June this year, and data from those individuals close contacts. They found that, on average, people began having symptoms 5.8 days after infection with Delta 1.8 days after they first tested positive for viral RNA. That left almost two days for individuals to shed viral RNA before they showed any sign of COVID-19.

    What Should I Do If I Have Coronavirus Symptoms

    If you have symptoms of Covid-19 however mild, self-isolate for at least 10 days from when your symptoms started.

    You should arrange to have a test to see if you have Covid-19. Do this over the phone or online. Do not go to a GP surgery, pharmacy or hospital.

    If you are not experiencing symptoms but have tested positive for Covid-19, you must self-isolate for at least 10 days, starting from the day the test was taken.

    If you develop symptoms during this isolation period, restart your 10-day isolation from the day you developed symptoms.

    You could be fined if you do not stay at home and self-isolate following a positive test result for Covid-19 or if you are contacted by NHS Test and Trace and instructed to self-isolate.

    Breakthrough Covid Infections: How Long Are Vaccinated People Contagious

    How long it can take for COVID-19 symptoms to develop

    There has been a lot of confusion about breakthrough COVID-19 infections recently what it means to test positive after being fully vaccinated, what the risk for developing long COVID is and how vaccinated people can spread the coronavirus.

    The truth is that scientists are still learning about post-vaccination infections and are still digging for answers to these questions, including how long people with breakthrough infections are contagious. But given the data available so far, most infectious disease specialist agree it is most certainly less than unvaccinated people who get COVID-19.

    Numerous studies have found that vaccinated people who test positive generally clear the virus out much faster than unvaccinated people who are infected, suggesting that those with breakthrough cases are most likely contagious for a shorter period of time.

    Some evidence suggests that vaccinated people, on average, clear the virus out within five to six days, whereas it generally takes unvaccinated people seven to 10 days. According to infectious disease specialists, this adds up vaccination teaches the immune system how to deal with COVID, so if youre exposed, your body can get a head start on attacking the virus and clearing it out quicker.

    Do Adults Younger Than 65 Who Are Otherwise Healthy Need To Worry About Covid

    Yes, they do. Although the risk of serious illness or death from COVID-19 increases steadily with age, younger people can get sick enough from the disease to require hospitalization. And certain underlying medical conditions may increase the risk of serious COVID-19 for individuals of any age.

    Everyone, including younger and healthier people, should get the vaccine once they are eligible, to protect both themselves and their community. Vaccines offer excellent protection against moderate to severe disease, hospitalization, and death. While youre also less likely to spread the virus once youve been vaccinated, the Delta variant is more capable than the original virus of getting into cells that line the nose, mouth, and throat. Once these variants get inside the cells, they rapidly make copies of themselves, increasing what is called the viral load. Thats why people who are fully vaccinated can still carry greater amounts of the Delta variant, making it more likely that they could spread the virus to others.
