Coronavirus COVID-19: what happenes to body if you get infected

Coronavirus: what it does to body 
The coronavirus emerged in only December last year, but already the world is dealing with pandemic of virus and disease it cause-COVID-19  


For the vast majority of people - more the 80% the virus will cause only mild symptoms and pass like a comman cold. The country's aggregate case fatality ratio is low because India has more young patients than other countries. The common perception is that the COVID-19 fatality rate in india is probably the lowest in the world, it seems broadly valid in the sense that India's rate at 2.8% is much lower.

Incubation period 
This is when the coronavirus is establishing itself. Coronavirus work by getting inside the cells your body is made of and hijacking them. 
The coronavirus which is also called SARS-CoV-2, can invade your body when you breathe it in, after some one coughs nearby or you touch a contaminated surface and then your face.
It first infects the cells lining your throat, airways and lungs and turns them into "coronavirus factories" that spew out huge numbers of new viruses that go on to infect yet more cells.
At this early stage, you will not be sick and some people may never develop symptoms.
The incubation period, the time between infection and first symptoms appearing, varies widely, but five days on average.

Coronavirus COVID-19 affects lungs 
  • As with other coronavirus illnesses including SARS, MERS, and the common cold coronavirus COVID-19 is a respiratory disease, so the lungs usually affected first 
  • Early symptoms include fever, cough, and shortness of breath. These appear as soon as 2 days, or as long as 14 days after exposure to the virus 
  • Cough is more common, that occurs in 68 to 83% of people who show up at the hospital with COVID-19 
  • 70 % of patients experience fewer when infected with COVID-19
  • Only 11 to 14% had shortness of breath 
  • Other less common symptoms included confusion, headache, nausea, and diarrhea 
Other organs affected by Coronavirus COVID-19
  • The lungs are the main organs affected by Coronavirus COVID-19.
  •  In serious case the rest of body can also be affected.
Stomach and Intestines 
  • Some people with COVID-19 have reported gastrointestinal symptoms, such as nausea or diarrhea, although these symptoms are much less common than problem with lungs 
  • Earlier reports identified the viruses that cause SARS and MERS in intestinal tissue biopsies and stool samples 
  • Two recent studies reports that stool samples of some people with coronavirus COVID-19 tested positive for the virus 
Heart and blood vessels 
  • COVID-19 can also affect the heart and blood vessels. This may show up as irregular heart rhythm, not enough blood getting to the tissues, or blood pressure low enough that it requires medication 
  • There is also signs that COVID-19 may cause the blood clot more easily. This clot could increase the risk of stoke or heart attack 
Liver and kidney 
  • When liver cells are inflamed or damaged, they can leak higher than normal amounts of enzymes into the bloodstream
  • Elevated liver enzymes aren't always a sign of serious problem, but this was seen in people with SARS or MERS 
  • Some people hospitalized with COVID-19 have also had acute kidney damage. This also occurred with SARS and MERS 
  • During the COVID-19 outbreak, scientists even found the virus that causes illness in the tubules of the kidneys
  • There is little evidence through, to show that virus directly caused the kidney injury, according to W.H.O.
Immune system   
  •  This can come in the form of inflammatory response, called cytokine storm. The immune cells produce cytokine to fight infection, but if too many are released, it can cause problems in the body 
  • A lot of damage in the body during COVID-19 is due to what we would call sepsis syndrome, which is due to complex immune reaction. The infection itself can generate an intense inflammatory response in the body that can affect the function of multiple organ system  
Medical treatment 
According to W.H.O. to date, there are no specific vaccines or medicines for COVID-19. Treatments are under investigation, and will be tested through clinical trials 

Prevention 
  • Clean your hand often.
  • Maintain a safe distance from anyone who is coughing or sneezing 
  • Don't touch your eyes, nose or mouth.
  • Cover your nose or mouth with your belt elbow or tissue when you cough or sneeze 
  • Stay home if you feel unwell 
  • If you have a fever, cough and difficulty breathing, seek medical attention.
  • Follow the directions of your local health authority.
Avoiding unneeded visits to medical facilities allows healthcare systems to operate more effectively, therefore protecting you and others .
