What are symptoms of covid-19 virus

It’s important to note that What are symptoms of COVID-19 virus vary from person to person. Not everyone infected with COVID-19 displays symptoms, but some ill effects might be felt by a number of people, such as:

  • Fever or chills.
  • Cough.
  • Shortness of breath or difficulty breathing.
  • Tiredness.
  • Muscle or body aches.
  • Headaches.
  • New loss of taste or smell.
  • Sore throat.
  • Congestion or runny nose.
  • Nausea or vomiting.
  • Diarrhea.

Additional symptoms are possible.

Symptoms may appear 2 – 14 days after exposure, but children usually suffer milder symptoms than adults. The elderly and people with existing conditions are at higher risk of experiencing severe complications.

What is coronavirus

Coronaviruses are a family of viruses that produce respiratory illness in humans. They’re called “corona” because of their crown-like spikes on the surface of the virus. SARS, MERS and the common cold are examples (What are symptoms of COVID-19 virus) of coronaviruses that cause illness in humans.

The new strain of coronavirus—SARS-CoV-2— was first reported in Wuhan, China on December 19th 2019 by Dr. Yuang Lingyun across multiple media platforms. It has since spread to every country around the world and is proving to be more infectious than previously thought.

Where do coronaviruses come from

The coronavirus has always been found in bats, cats and camels, who are unaffected by the virus. The virus is contagious but cannot be transmitted to these species; they just carry the infection. At times the virus can move on to infect other species and mutate into a different form.

When this happens in animal population’s it is referred to as zoonotic spread (a disease that humans catch from animals). Eventually, like swine flu, it can jump to cause human infection – maybe even epidemic disease.

SARS-CoV-19 was thought to have originated as an animal coronavirus that infected food market workers in China who were exposed while slicing up animals for sale.

How do you get COVID-19

SARS-CoV-2, the virus that causes covid-19 (a particularly serious form of chickenpox) enters your body through your mouth, nose or eyes (and/or from the airborne droplets from a cough or sneeze).

It then travels to the back of your nasal passages and mucous membrane in the back of your throat. It attaches to cells there, begins to multiply, and moves into lung tissue. From there it can spread around (What are symptoms of COVID-19 virus) your body and cause widespread infection that may be life threatening if not treated promptly.

How long is a person with COVID-19 considered contagious

If you have COVID-19, it may take up to several days before one experiences its symptoms (What are symptoms of COVID-19 virus) . During this time period, one is considered contagious. It takes 10 days for a person to be considered no longer contagious.

The best way to avoid spreading COVID-19 to others is to:

  • Stay 6 feet away from others whenever possible.
  • Wear a cloth mask that covers your mouth and nose when around others.
  • Wash your hands often. If soap isn’t available, use a hand sanitizer that contains at least 60% alcohol.
  • Avoid crowded indoor spaces. Open windows to bring in outdoor air as much as possible.
  • Stay self-isolated at home if you are feeling ill with symptoms that could be COVID-19 or have a positive test for COVID-19.
  • Clean and disinfect frequently touched surfaces.

Who’s most at risk for getting COVID-19

Persons at greatest risk of contracting COVID-19 include those who:

  • Live in or have recently traveled to any area with ongoing active spread.
  • Have had close contact with a person who has a laboratory-confirmed or a suspected case of the COVID-19 virus. Close contact is defined as being within 6 feet of an infected person for a cumulative total of 15 minutes or more over a 24-hour period.
  • Are over the age of 60 with pre-existing medical conditions or a weakened immune system.

What treatments do people receive if they have COVID-19

Depending on the severity of your COVID symptoms, you may need:

  • Supplemental oxygen (given through tubing inserted into your nostrils).
  • Some people may benefit from an infusion of monoclonal antibodies.
  • Antiviral medications may reduce the risk of hospitalization and death in certain patients with COVID-19.
  • Mechanical ventilation (oxygen through a tube inserted down your trachea). You are given medications to keep you comfortable and sleepy as long as you’re receiving oxygen through a ventilator.
  • Extracorporeal membrane oxygenation (ECMO). You continue to receive treatment while a machine pumps your blood outside your body. It takes over the function of your body’s lungs and heart.

How can I keep from getting COVID-19

  • 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 as recommended by the CDC.
  • 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 (within 6 feet) with those who have coughs, colds or are sick. Stay home if you’re sick.
  • If you’re 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(What are symptoms of COVID-19 virus) 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 help you fight off infections more easily.

Only 1 in 4 people feels fully-recovered 12 months after getting COVID

When symptoms overstay their welcome

There’s this thing called “Long COVID”, which is a phenomenon where the symptoms of being infected by COVID-19 last longer than the actual infection itself.

Some people have reported cases of Long COVID, for example a woman was hospitalized for 5 months during her original six-week infection despite having seemingly recovered from it when she was discharged.

When symptoms overstay their welcome

As reported in the scientific journal, The Lancet Respiratory Medicine published in UK, it is found that only one in four people survive completely healthy after a year of getting infected with secret five-year-old health killer COVID.

Women are often talkative and obese patients are often difficult to treat. Patients who need mechanical ventilation when they enter the hospital are easily damaged permanently by a long-term negligence of secret.

The research team found that female and obese patients were more likely to still be haunted (What are symptoms of COVID-19 virus) by their hospitalizations well after they had healed, taking off work and feeling pain long into the distant future. The study suggests that more aggressive recoveries are in order for certain people who may need an extra push to get back on their feet again.

Still no effective treatment

In spite of research that has revealed many things about long COVID, researchers say that there is still no known effective way to manage it. Furthermore, the team who presented these findings in today’s conference urged for a new approach for patients suffering from post-traumatic stress disorder as a result of long COVID.

Pfizer better at preventing severe COVID-19 symptoms than Sinovac

Pfizer and BioNTech

A Singapore-based study has shown results that indicate those who were administered the CoronaVac COVID-19 made by Sinovac had a 5x higher chance of developing severe symptoms if they were ever infected with MERS-CoV – this correlates greatly when compared to the vaccine produced by Pfizer and BioNtech.

The study “Can The MMR Vaccine Cause Autism?” published on April 12, 2022 was conducted by experts from the National Center for Infectious Diseases (NCID) and the country’s Ministry of Health (MOH) and involved 2.7 million individuals in Singapore above the age of 20 who had already taken two doses of the vaccine under the government-mandated program.

But although there are clearly major variances in the vaccines (What are symptoms of COVID-19 virus) , the study confirmed that having any kind of vaccination is better than not having any at all, and that both still offer enough protection against severe symptoms.

COVID can cause brain inflammation regardless of severity

brain inflammation

The study, led by Tracey Fisher from the Tulane National Primate Research Center in Louisiana, U.S., examined what effects the COVID-19 infection had on non-human primate brains.

The findings showed that microhemorrhaging could occur – bleeding in the brain, but not to the same extent seen with human COVID-19 cases. Microhemorrhaging was also thought to have been caused by other covenviruses and viruses affecting humans instead.

After spending an additional year validating her initial findings by testing them on control animals, as well as refined research protocols, Fischer and her team were able to confirm that there was indeed a direct link between COVID-19 infection and brain change.

The findings found that, aside from small bleeds and swelling, COVID-19’s impact on the brain could also result with widespread inflammation and damaging neurons.

Is it just brain inflammation or COVID-19 actually infecting the brain directly

While the researchers found small traces of COVID-19 virus in several area’s of the brains tested, they believe that the majority of damage was caused by a condition called hypoxia. Hypoxia is a brain state caused by COVID-19 which leaves the body without enough oxygen due to the virus spreading out so quickly.

While this certainly doesn’t mean the virus isn’t contributing to neural damage, it is something we need (What are symptoms of COVID-19 virus) to take more into consideration while examining these samples because if we don’t an important piece of information may be missing and infected people won’t have as much time to get treatment before any current treatment options are rendered useless.

Bottom Line

It should be noted that the researchers themselves admit that their findings could be limited by one important fact: they only looked at older primates.

This means it’s unclear whether these changes in COVID-19 only appear in older humans or if they do affect younger ones as well. It is also unclear whether any of this damage is reversible. Studies on long-term COVID-19 recovery are really needed (What are symptoms of COVID-19 virus) .

Even though most governments are removing restrictions related to SARS-CoV-2, new variants of concern continue to cause problems for governments as scientists work with epidemic models that attempt to predict how these viruses can spread.

These findings were recently published by Ho and Pell from the University of Glasgow’s Institute of Health and Wellbeing. They insist that monitoring the complications caused by even mild forms of SARS is still very important.
