COVID-19 AND ITS INFECTION PROCESS


Worldhealth organizations, advise the public that does not take this disease and warning lightly and always remain vigilant and watchful for symptoms like cough, fever, and difficulty in breathing. These symptoms may be, nowadays, caused by new Novel Corona Virus COVID or SAR-CoV-2

This viral infection takes 10 to 12 days to appear and maybe diagnose after 5 days when a person is exposed to the virus. Here we will discuss how COVID-19 affects the body.

COVID-19 INFECTION

According to the WHO, the virus transmits through respiratory water droplets from an infected person to a healthy person. When an infected person sneezes or cough its respiratory droplets travel within the air for up to 4-5 Feet or it may rest on any object, which when touch by a healthy person, may transmit to him/her. The virus mainly enters the body through the nose but some researchers concluded that it may enter the body through ears, eyes, and mouth. The virologist also states that there are many things that still not known about the COVID-19 but primarily it is established that the virus enters through the noise and the virus is a member of the Corona Virus family.

 COVID-19 SYMPTOMS

According to us center of disease control and prevention, the life cycle of the disease is 14 days, when initially the symptoms appear. Initially, it takes 5-10 days for the symptoms to appears, an average of five days. When the first symptoms appear and the patient came positive for COVID-19, there is standard 14 days quarantine for the patient. It is most likely that the infection can be immune in this period by the body's immune system.
When the virus enters the body, it starts infecting the epithelial cell in the lining of the lungs. The protein on the virus attaches to the host cells begins to replicate itself until it kills the cell.
This first happens in the upper respiratory system tract of the human body like noise, mouth larynx, and bronchi

The patients start experiencing an initial or mild version of the symptoms; dry cough, fever, back muscle pain, headache and difficulty in breathing. These symptoms are the same as common flu that’s why usually due to panic among the masses; people consider flu as COVID-19.
COVID-19 AND ITS INFECTION PROCESS


Severe symptoms, like pneumonia, appears when the infection reaches the lower parts of the respiratory system, alveoli. most of the cases show mild symptoms because the body's immune system locked the infection in the upper respiratory system, such cases require no hospitalization but quarantine is necessary to curtain the spreading of infection. Those who have a weak immune system may experience severe symptoms and immediate hospitalization and intensive care are needed for them otherwise, they may die from this.

In severe cases, when the infection reaches the small sack-like structure in the lung, alveoli which pumped oxygen to the bloodstream, the infection starts killing the cell and the immune cell also reached to alveoli and a fight starts between virus and immune cells which cause choking of the alveoli and stops the blood supply to other body organs mainly kidney, liver, and brain. It is a fight between immune cells and viruses, if immune wins, body survives, if not, organs damage and cause death.
Due to low oxygen supply to the organ of the body in COVID-19 patients with severe symptoms, are put on a ventilator to get an adequate supply of clean oxygen. The severe symptoms are most common in those people who have a weak immune system like old age, more than 60 years, people with respiratory disease and chain smokers.

The prevention is more important than the cure that’s are; there must be social distancing now a day because the virus attack is on the peak. The people with weak immune must keep themselves in isolation and avoid any contact with the infected person and regular hand washing. The preventive measure issued by WHO must be followed and conveyed to other

COVID-19 is usually confused this flu and people rushed to already crowded hospital for a checkup. if you are not in touch with anybody who just arrived from the area which is affected by the virus nor there is any case in your area, then having these symptoms are not COVID-19 but flu or just fear. Similarly, if you know that you were in touch with an infected person and now you are also experiencing the same symptoms, must visit the COVID-19 diagnose center and test yourself for infection for you sack and your family sack
