Symptoms of cornavirus,Covid-19& its prevention.

 

The main symptoms include:

·      Fever

·      Coughing

·      Shortness of breath

·      Trouble breathing

·      Fatigue

·      Chills, sometimes with shaking

·      Body aches

·      Headache

·      Sore throat

·      Loss of smell or taste

·      Nausea

·      Diarrhea

The virus can lead to pneumonia, respiratory failure, septic shock, and death. Many COVID-19 complications may be caused by a condition known as cytokine release syndrome or a cytokine storm. This is when an infection triggers your immune system to flood your bloodstream with inflammatory proteins called cytokines. They can kill tissue and damage your organs.

If you notice the following severe symptoms in yourself or a loved one, get medical help right away:

·      Trouble breathing or shortness of breath

·      Ongoing chest pain or pressure

·      New confusion

·      Can’t wake up fully

·      Bluish lips or face

Strokes have also been reported in some people who have COVID-19. Remember FAST:

·      Face. Is one side of the person’s face numb or drooping? Is their smile lopsided?

·      Arms. Is one arm weak or numb? If they try to raise both arms, does one arm sag?

·      Speech. Can they speak clearly? Ask them to repeat a sentence.

·      Time. Every minute counts when someone shows signs of a stroke. Call 911 right away.

If you’re infected, symptoms can show up in as few as 2 days or as many as 14. It varies from person to person.

According to researchers in China, these were the most common symptoms among people who had COVID-19:

·      Fever 99%

·      Fatigue 70%

·      Cough 59%

·      Lack of appetite 40%

·      Body aches 35%

·      Shortness of breath 31%

·      Mucus/phlegm 27%

Some people who are hospitalized for COVID-19 have also have dangerous blood clots, including in their legs, lungs, and arteries.

Coronavirus Transmission

How does the coronavirus spread?

SARS-CoV-2, the virus, mainly spreads from person to person.

Most of the time, it spreads when a sick person coughs or sneezes. They can spray droplets as far as 6 feet away. If you breathe them in or swallow them, the virus can get into your body. Some people who have the virus don't have symptoms, but they can still spread the virus.

You can also get the virus from touching a surface or object the virus is on, then touching your mouth, nose, or possibly your eyes. Most viruses can live for several hours on a surface that they land on. A study shows that SARS-CoV-2 can last for several hours on various types of surfaces:

·      Copper: 4 hours

 

Coronavirus Diagnosis

Call your doctor or local health department if you think you’ve been exposed and have symptoms like:

·      Fever of 100 F or higher

·      Cough

·      Trouble breathing

In most states, decisions about who gets tested for COVID-19 are made at the state or local level.

A swab test is the most common method. It looks for signs of the virus in your upper respiratory tract. The person giving the test puts a swab up your nose to get a sample from the back of your nose and throat. That sample usually goes to a lab that looks for viral material, but some areas may have rapid tests that give results in as little as 15 minutes.

If there are signs of the virus, the test is positive. A negative test could mean there is no virus or there wasn’t enough to measure. That can happen early in an infection. It usually takes 24 hours to get results, but the tests must be collected, stored, shipped to a lab, and processed.

The FDA is granting emergency use authorizations for tests that don’t have full approval yet. These include a home nasal swab test, a home saliva test, and tests that check your blood for things called antibodies. Your immune system makes antibodies in response to an infection.

A swab test can only tell whether you have the virus in your body at that moment. But an antibody test can show whether you’ve ever been exposed to the virus, even if you didn’t have symptoms. This is important in officials’ efforts to learn how widespread COVID-19 is. In time, it might also help them figure out who’s immune to the virus.

The FDA is working with laboratories across the country to develop more tests.

Coronavirus Prevention

Coronavirus Prevention

Take these steps:

·      Wash your hands often with soap and water or clean them with an alcohol-based sanitizer. This kills viruses on your hands.

·      Practice social distancing. Because you can have and spread the virus without knowing it, you should stay home as much as possible. If you do have to go out, stay at least 6 feet away from others.

·      Cover your nose and mouth in public. If you have COVID-19, you can spread it even if you don’t feel sick. Wear a cloth face covering to protect others. This isn’t a replacement for social distancing. You still need to keep a 6-foot distance between yourself and those around you. Don’t use a face mask meant for health care workers. And don’t put a face covering on anyone who is:

o  Under 2 years old

o  Having trouble breathing

o  Unconscious or can’t remove the mask on their own for other reasons

·      Don’t touch your face. Coronaviruses can live on surfaces you touch for several hours. If they get on your hands and you touch your eyes, nose, or mouth, they can get into your body.

·      Clean and disinfect. You can clean first with soap and water, but disinfect surfaces you touch often, like tables, doorknobs, light switches, toilets, faucets, and sinks. Use a mix of household bleach and water (1/3 cup bleach per gallon of water, or 4 teaspoons bleach per quart of water) or a household cleaner that’s approved to treat SARS-CoV-2. You can check the Environmental Protection Agency (EPA) website to see if yours made the list. Wear gloves when you clean and throw them away when you’re done.

There’s no proof that herbal therapies and teas can prevent infection.

COVID-19 preparation tips

In addition to practicing the prevention tips listed above, you can:

·      Meet as a household or larger family to talk about who needs what.

·      If you have people at a higher risk, ask their doctor what to do.

·      Talk to your neighbors about emergency planning. Join your neighborhood chat group or website to stay in touch.

·      Find community aid organizations that can help with health care, food delivery, and other supplies.

·      Make an emergency contact list. Include family, friends, neighbors, carpool drivers, doctors, teachers, employers, and the local health department.

Choose a room (or rooms) where you can keep someone who’s sick or who’s been exposed separate from the rest of you. Coronavirus Prevention
