Severe Symptoms Of Covid
Moderate symptoms can progress into severe symptoms suddenly, especially in people who are older or who have chronic medical conditions like heart disease, diabetes, cancer or chronic respiratory problems. There have even been reports of people with mild to moderate symptoms feeling better and then suddenly getting worse and requiring hospitalization.
The Centers for Disease Control and Prevention says if you begin to show severe symptoms of COVID-19 or what they call emergency warning signs you should go to the emergency room or call 911 immediately.
Emergency warning signs of the coronavirus include:
- Constant trouble breathing
- Persistent chest pain or pressure
- Blue lips or face
How Soon After Becoming Infected With Covid
The time between becoming infected and showing symptoms can range from 2 to 14 days. The average time before experiencing symptoms is five days. Symptoms can range in severity from very mild to severe. In about 80% of patients, COVID-19 causes only mild symptoms, although this may change as variants emerge.
Next Symptoms: Week 2
COVID-19 may then cause a cough, sore throat, and body aches or headaches. The Frontiers in Public Health study also suggested that COVID-19 could then cause nausea and vomiting, which would develop sooner than it would in similar respiratory infections, such as MERS or SARS.
In severe cases, COVID-19 can require hospitalization. A 2020 study in The Lancet suggests that this typically occurs after 7 days from the onset of symptoms.
Some people will experience acute respiratory distress syndrome after 9 days. This is where the lungs fail to provide the body with sufficient oxygen. According to the Center for Disease Control and Prevention , around 20% to 42% of people hospitalized with COVID-19 experience this condition.
In these and other severe cases, doctors may admit people to an intensive care unit around 10 days after symptom onset. Around 26% to 32% of people hospitalized with COVID-19 will require treatment in an intensive care unit.
However, the type and order of symptoms will vary from person to person. For example, some people will experience nausea, vomiting, or diarrhea before fever or coughing. Others will experience no symptoms at all.
CDC , most people can be around other people after 10 days since their symptoms first appeared, as long as they have not experienced fever for 24 hours and other symptoms are improving.
People with a positive test result but without COVID-19 symptoms are still infectious and should isolate for 10 days after the date of the test.

Which Vaccines Has The Fda Approved And Authorized For Covid
In August 2021, the FDA granted full approval to the mRNA COVID-19 vaccine developed by Pfizer and BioNTech. This vaccine had received emergency use authorization in December 2020. The mRNA COVID-19 vaccine developed by Moderna also received EUA in December 2020. The Johnson & Johnson adenovirus vaccine was granted EUA by the FDA in late February 2021 however, in December 2021, the CDC stated a preference for vaccination with either of the mRNA vaccines.
The Pfizer/BioNTech vaccine has also been authorized for children ages 5 to 17 years, though children ages 5 to 11 will receive a lower dose.
In addition, booster doses of all three vaccines have been authorized for eligible recipients.

A study from Wuhan, the epicentre of the coronavirus outbreak, outlined how Covid-19 progresses – with fever, fatigue and shortness of breath all developing at different times.
The analysis includes adults with Covid-19 admitted to Jinyintan Hospital and Wuhan Pulmonary Hospital.
It’s important to note that a third of coronavirus cases have no symptoms at all.
The government launched free rapid testing across the UK for people with no symptoms – this is so that the virus has less chance of spreading unknowingly.
But if you have any of the three key symptoms, a high temperature, loss of taste and smell or a new persistent cough you should get a PCR test.
There are also conditions such as long Covid.
This is when a person has had Covid and got over the intial virus – but still suffers debilitating symptoms months on.
Here, with the help of this study, we take you through the coronavirus symptoms timeline.

Not Everyone Feels Short Of Breath
The main risk factors that predict progression to severe COVID include: symptoms lasting for more than seven days and a breathing rate over 30 per minute. Faster breathing is to compensate for the less-efficient transfer of oxygen to lung blood vessels, due to inflammation and fluid build-up in the airways.
But how diseases progress is rarely straight forward, making it impossible to give definitive lists of red flag symptoms to look out for.
Some COVID patients have happy or silent hypoxia. This features low levels of oxygen in the blood but there arent the usual signs of respiratory distress normally seen with such low oxygen levels, including feeling short of breath and faster breathing.
However, these patients can suddenly deteriorate. Faster and deeper breathing are early warning signs of failing lungs.
What Do I Need To Know About The Delta Variant
The Delta variant is different from previous SARS-CoV-2 variants that have made their way to the US. Its highly contagious and may cause more severe disease. It is also more likely than previous variants to be spread by vaccinated people experiencing breakthrough infections.
Evidence presented to the CDC showed the Delta variant to be much more contagious than previous variants, with a risk of transmission similar to chickenpox. It also appears that people who are infected can spread the virus for longer periods of time.
In addition, people who are vaccinated and then get infected can also spread the virus to others, perhaps to the same extent as those who are unvaccinated. However, people with breakthrough infections appear to be contagious for a shorter period of time.
Finally, international studies point to the Delta variant being more likely to cause severe disease.
The good news is that while vaccination may be less effective at preventing infection and spread of the Delta variant, it is still highly protective against severe disease, hospitalization, and death. Get the COVID-19 vaccine if you have not already done so.

How Long It Will Take To Recover
While early Covid-19 symptoms remain pretty similar across different variants, what has changed is the course of illness, according to Dr. Roy Gulick, chief of infectious disease at NewYork-Presbyterian/Weill Cornell Medical Center. Some patients never develop more than mild symptoms, while others see their fever or other symptoms start to improve about five to six days after they first get sick, he said. The period between days 5 and 10 is critical when you have Covid-19 because some people may experience a turn for the worse right around then.
Be Aware: A Mild Case Of Covid
Healthcare workers on the frontline are starting to report a disturbing finding when it comes to caring for COVID-19 patients.
Time and again, they are seeing patients who come to the emergency room with mild symptoms that can be managed at home then, 1-2 days later, these patients are back and theyre drastically sicker. One ER doc describes it like this: Its slow, slow, slow, and then bang people are suddenly really sick and crashing. It can be really scary to see.
Some patients are describing a similar experience. They may be having mild symptoms like cough, fatigue, and muscle aches for a few days, and then suddenly experiencing severe shortness of breath, making it almost impossible to fill their lungs with air.
Doctors are also finding that some patients report that they are starting to feel a little better after about a week, then over the course of 1-2 days, the symptoms come back with a vengeance requiring higher level care in the hospital including high levels of oxygen and breathing tube placement.
What does the spectrum of COVID-19 illness look like?
From current data, it looks like about 25-30% of people can be asymptomatic or pre-symptomatic spreading COVID-19 without even knowing that they have it. About 80% of people go on to have mild to moderate illness, and dont go past this stage. But about 16% of people do worsen and go on to have more serious disease.
Who is at higher risk of progressing?
The short answer: We dont know.

When And How Often To Take A Covid
Like the previous Omicron variant, BA.2 moves fast and people who do develop symptoms, may start feeling sick two to three days after an exposure to the coronavirus, said Aubree Gordon, an epidemiologist at the University of Michigan. Some of the early symptoms may be very similar to a cold or flu, and include a sore throat, nasal congestion, cough or fever. Some people also report a loss of taste or smell, muscle aches, headaches, gastrointestinal issues and skin rashes. I would definitely test as soon as I had any symptoms, Dr. Gordon said.
If you use a home test and get a negative result, you should continue taking precautions and test again 24 to 48 hours later, Dr. Gordon said. It could be that the virus simply hasnt ramped up to levels detectable on a rapid test yet. If symptoms persist and you still test negative at home a few days later, you may want to get a lab-based P.C.R. test, which is more sensitive at detecting traces of the coronavirus.
Even if youre already vaccinated and boosted, your protective antibodies can wane over time, making you vulnerable to an infection. The Food and Drug Administration has authorized second boosters for older adults and those with underlying medical conditions that put them at high risk for severe disease. And while a recent bout with Omicron may provide some immunity, it is possible to be reinfected with the new version.
How Can I Prevent Getting The Novel Coronavirus
The best defense to prevent getting COVID-19 is to get vaccinated. You should also follow the same steps you would take to prevent getting other viruses, such as the common cold or the flu.
- Wash your hands for at least 20 seconds especially before eating and preparing food, after using the bathroom, after wiping your nose, and after coming in contact with someone who has a cold.
- Wear a multilayered cloth facemask that fits snugly on your face and covers your mouth, nose and chin.
- Avoid touching your eyes, nose and mouth to prevent the spread of viruses from your hands.
- Cover your mouth and nose with a tissue when sneezing and coughing or sneeze and cough into your sleeve. Throw the tissue in the trash. Wash your hands afterward. Never cough or sneeze into your hands!
- Avoid close contact with those who have coughs, colds or are sick. Stay home if you are sick.
- If you are prone to sickness or have a weakened immune system, stay away from large crowds of people. Follow the directions of your healthcare authorities especially during outbreaks.
- Clean frequently used surfaces with a virus-killing disinfectant.
- Use hand sanitizers that contain at least 60% alcohol if soap and water are not available.
- Greet people with a friendly gesture instead of shaking hands.
- Get enough sleep, eat a healthy diet, drink plenty of liquids and exercise if you are able. These steps will strengthen your immune system and enable you to fight off infections easier.

Infection Prevention Is Key
Now that all adults are eligible to be vaccinated , the CDC is working with partners across the country to make sure everyone has the information they need.
The CDC says all adults 18 or older should get a booster shot six months after completing their primary vaccination series if they started with Pfizer-BioNTech or Modernaor two months after getting the J& J single-shot vaccine. Teenagers ages 16 or 17 may also get the Pfizer-BioNTech booster, which the FDA authorized for that age group in December 2021. A mix-and-match policy means that any of the three COVID-19 vaccines available in the U.S. can be taken as a booster shot, regardless of which vaccine a person had for their primary vaccination.
A third dose of Pfizer-BioNTech or Moderna was recommended at least 28 days after the second dose to help people with certain immunocompromising conditions reach a level of immunity they were not able to reach after two doses. In October, the CDC issued additional interim guidelines saying that moderately and severely immunocompromised people who received an mRNA vaccine, and are 18 and older, may receive a booster dose of any COVID-19 vaccine at least six months after their third dose. The CDC also recommended that anyone who got the single-shot Johnson & Johnson vaccine get a booster at least two months later.
Information on where to get the vaccine, including which sites have doses available, is available through a CDC tool called VaccineFinder.

The Reactivation Of A Previous Virus May Be Causing Long Covid Symptoms
A study published in the journal Cell found reactivation of the Epstein-Barr Virus to be a factor in developing long COVID. EBV is the virus that causesmononucleosis. The virus is also associated with chronic fatigue syndrome, which resembles long COVID symptoms for some people. According to Nam Tran, a professor of clinical pathology, the usual screening test for EBV, known as a heterophile antibody test, is not appropriate for evaluating EBV reactivation. But there are other serology tests blood tests that are. One EBV serology test looks at four different markers to determine if the infection is acute, recent, past or a reactivation. Another test looks at the EBV viral load and may be preferred over serology when evaluating reactivation cases. The EBV serology or EBV viral load test can reveal if reactivation may be contributing to some symptoms experienced by long COVID patients, Tran said.

Mental Health Issues After Covid
After surviving COVID-19, some people are left with lingering anxiety, depression and other mental health issues. Physical changes such as pain and weakness can be complicated by long periods of isolation, stress from job loss and financial difficulties, and grief from the deaths of loved ones and the loss of good health.
Patients who were hospitalized have a particularly challenging recovery. Brigham says Post-intensive care syndrome, or PICS, puts COVID-19 survivors and other people who have spent time in the ICU at a higher risk for problems with mental health, cognition and physical recovery.
Megan Hosey, Ph.D., a rehabilitation psychologist, says that prolonged time in the ICU can cause delirium. The strange surroundings, multiple mind-altering medications, isolation and loss of control can leave patients with lasting and recurrent sensations of terror or dread, including post-traumatic stress disorder .
Many patients have hallucinations where they believe that medical providers are trying to harm them, Hosey says. We’ve had patients tell us things like I thought I was being buried alive when they were being put into an MRI.
What Causes A Covid Cough
Its not surprising COVID causes a cough, because the virus affects our respiratory tract, from our nasal passages right down to our lungs.
Coughing is one of the bodys ways of getting rid of unwanted irritants such as viruses, dust and mucus. When something foreign is detected in the respiratory tract, a reflex is triggered to cause a cough, which should clear the irritant away.
While this is an effective protective mechanism, its also the way the COVID virus spreads. This is one reason the virus has so effectively and quickly travelled around the world.

Duration Of The Symptoms
Now lets talk about the duration of the symptoms. The Centers for Disease Control and prevention mentioned on its platform that once people start developing symptoms of COVID-19, it can last in your system for around 10 days.
We are only talking about the cases where the infection is normal, and a person does not require any hospitalization. The current variants of COVID infecting The United states are much more infectious, but they do not impose any fear of hospitalization.
So, there is a probability that people who start developing symptoms might get better after 7 to 10 days.
When you are counting the first day of your symptoms, the Centers for Disease Control and Prevention suggest you not count the pre-symptom time frame. Your first day of symptoms is going to be the first full day since you start experiencing the symptoms.
The time frame between exposure to the virus and developing any symptoms related to COVID-19 is going to be counted as a pre-symptom time frame.
The Centers for Disease Control and Prevention suggest everyone isolate themselves if they are experiencing any symptoms related to COVID-19.
What Vaccines Are In Use Or In Late
The Food and Drug Administration has granted Emergency Use Authorization for three coronavirus vaccines. Both the Pfizer and Moderna vaccines are administered in two doses. Its important for you to get both doses of the vaccine for maximum protection. Pfizers vaccine doses are given 21 days apart and its authorized for use in those age 5 and older. Doses of the Moderna vaccine are given 28 days apart, and its authorized for use in those age 18 and older. Both vaccines are highly effective. Another effective option is Johnson & Johnsons single-dose vaccine, which is authorized for use in individuals 18 years of age and older.
