COVID 19

What is COVID 19?

A group of viruses known as coronaviruses can make people sick with respiratory conditions. Because the virus's surface is covered in spikes that resemble crowns, they are known as "corona." Examples of coronaviruses that affect humans include acute respiratory syndrome ( sars syndrome (SARS), Middle East respiratory syndrome (MERS), and the common cold.

SARS-CoV-2, a new coronavirus strain, was first discovered in Wuhan, China, in December 2019. Since then, it has spread to every nation on earth.

COVID Origination:

Bats, cats, and camels are frequently the hosts of coronaviruses. Animals are not infected by the viruses, which live there. These viruses can occasionally spread to affect various animal species. As they spread to other species, viruses have the potential to evolve (mutate). The virus eventually has the ability to spread from animal to human species. The initial SARS-CoV-19 infections are believed to have occurred in a food service industry that sold meat, fish, and live animals.

Causes:

Camels, cats, and bats are frequently found to have coronaviruses. The viruses exist in the animals but do not infect them. Occasionally, these viruses then spread to various animal species. As they spread to other species, the viruses might alter (mutate). The virus can eventually spread from animal to human populations. The first SARS-CoV-19 victims are believed to have acquired the disease at a grocery store that sold meat, fish, and live animals.

The COVID-19 virus, known as SARS-CoV-2, enters the body through the mouth, nose, or eyes (directly from the airborne droplets or from the transfer of the virus from your hands to your face). The membrane that lines in the back of the throat and the return of your respiratory system are the next places it goes. It binds to those cells, starts to grow, and then invades lung tissue. The virus can then spread to other bodily tissues from there.

Transmission:

• Most likely, coronavirus will spread:
• When an infected individual coughs, sneezes, talks, sings or breathes close to you, respiratory water particles released into the air carry the virus. If you breathe in these droplets, you could become infected.
• Coronavirus can also spread through handshaking or another close contact with an infected individual before touching your face.
• It may take a few days for COVID-19 symptoms to appear, but during this time, you are still contagious. Ten days after the onset of your symptoms, you are no longer contagious.
• The best way to stop others from contracting COVID-19 is to:
• When possible, maintain a 6-foot distance from others.
• When around people, put on a cloth mask that encloses your mouth and nose.
• Regularly wash your hands. Use antibacterial wipes with at least 60% alcohol if soap is not readily available.
• Do not enter crowded indoor areas. Open windows to let in as much fresh air as you can.
• If you are experiencing symptoms that could be COVID-19 or if the COVID-19 test results in a positive result, isolate yourself at home.
• Frequently touched surfaces should be cleaned and disinfected.

Symptoms:

The incubation period (the interval between being infected and exhibiting symptoms) can last anywhere between two and 14 days. Five days on the average pass before symptoms appear. The severity of the symptoms can range from very gentle to severe. Approximately 80% of people who have COVID-19 only experience minor symptoms, though this may start changing as new variants are discovered.

The symptoms of COVID-19 differ from person to person. In fact, some infected individuals never experience any symptoms (asymptomatic). People with COVID-19 typically describe some of the following symptoms:

• Chills or a fever.
• Cough.
• Breathing problems or shortness of breath.
• Tiredness.
• Body or muscle aches.
• Headaches.
• New loss of smell or taste.
• Throat pain
• Runny or congested nose.
• Vomiting or nauseous.
• Diarrhea.
• There may be additional symptoms.

Two to 14 days after virus exposure, symptoms might start to show up. Similar symptoms exist in children, but they are typically less severe than in adults. A more serious COVID-19 complication is more likely in older adults and those with serious underlying medical conditions.

Risk Factors:

The following groups of people are most at risk of getting COVID-19:

•  Reside in an area where the spread is still active or have recently visited one.
• Have been in close contact with someone who has the COVID-19 virus, either in a confirmed or suspected case according to a lab. Close contact is defined as spending a cumulative total of 15 minutes or more, over the course of a 24-hour period, within 6 feet of an infected person.
• Are older than 60 and have weakened immune systems or pre-existing medical conditions.

Diagnosis:

A laboratory test is used to diagnose COVID-19. To send for testing, your healthcare provider might take a sample of your secretions or swab your throat or nose. Call your medical professional if you:

Feel unwell with a fever, a cough, or breathing issues.

Have had frequent contact with someone who carries or is thought to carry COVID-19.

Your doctor will inquire about your symptoms and let you know whether you need to get tested for COVID-19.

Self-Isolation:

• As of right now, the CDC advises self-isolation until you've satisfied both of the following conditions:
• Your symptoms have now been present for five days, and they are getting better.
• You haven't taken any fever-reducing medication in the past 24 hours, and you haven't had a fever.
• To minimize communication with other relatives while at home, try to isolate yourself in a different room of your house. If you are unable to remain completely alone in a separate room, keep a distance of 6 feet from other people, wear a cloth mask, wash your hands frequently with soap for yourself and your family, and frequently disinfect shared spaces.
•  After your moment of self, you don't need to undergo another test. However, because every situation is different, heed the advice of your healthcare provider for tests
• The CDC's requirements do not apply to you if you have a weak immune system or have experienced a severe COVID-19 infection. After your symptoms started, you might need to remain at home for up to 20 days. Discuss your situation with your healthcare provider.
• If: You need to be in a five-day quarantine
• You still lack some vaccinations.
• Since receiving your second dose of vaccination, more than six months have passed without receiving a booster.
• For an extra five days after this, you must wear a mask that fits properly whenever you are around people. If at all possible, the CDC advises testing on day five. Depending on the strain variations and the accessibility of testing, this quarantine duration may change.

Treatment:

Depending on how severe your symptoms are, there are different COVID-19 treatments. No particular antifungal medication or immunotherapy is advised if you are not in the hospital or do not require additional oxygen.

• You might require: Depending on how severe your COVID symptoms are.
• Additional respiration (given through tubing inserted into your nostrils).
• An injection of monoclonal antibodies might be helpful for some people.
• Antiviral drugs may lower the risk of hospitalization and death in some COVID-19 patients.
• Ventilation technology (oxygen through a tube inserted down your trachea). As long as you're using a ventilator to get oxygen, you're given medications to make you feel at ease and sleepy.
• Oxygenation of extracorporeal membranes (ECMO). While a device pumps your blood outside of your body, you keep receiving treatment. It takes over the function of your body and heart.
