Body’s reaction when infected with Corona Virus

Windowofworld.com – The body’s reaction when infected with the Corona virus is to form an immune system to eradicate the virus. If the immune system is strong, the virus will die. However, in people whose immune systems are weak, the Corona virus can be difficult to fight so that severe symptoms and fatal complications arise.

Corona virus can be transmitted between humans through sputum splashes or saliva of people with COVID-19 when they are coughing or sneezing. Sputum and saliva can enter the body of others through the eyes, nose, or mouth.

In addition, the Corona virus can also enter a person’s body through hands that have been contaminated with this virus when touching objects that contain splashes of saliva with a COVID-19 sufferer, if the person touches his nose or mouth before washing his hands.

What Happens When Corona Virus enters the Body?

When it enters the body, the Corona virus will stick to the walls of the respiratory tract cells and lungs, then enter it to multiply there.

This process will be detected by the immune system. After that, the immune system or immune system will react by sending white blood cells and forming antibodies to fight and kill the virus.


When there is a body’s reaction to the Corona virus, several symptoms will appear, such as fever. These symptoms will usually appear within 2–14 days after exposure to the Corona virus.

In some people who are infected with the Corona virus, the body’s immune system reaction will be successful against the virus, so the symptoms subside and the person recovers by itself.

However, if a person’s immune system is not strong enough to fight the Corona virus or overreact, the person will experience more severe symptoms of COVID-19, which is a high fever and shortness of breath, or can also experience organ damage.

This is more risky to occur in the elderly or people who have previous comorbidities, such as diabetes, cancer, and HIV.

Some Complications of Corona Virus Infection

Some sufferers of Corona virus infection have no symptoms or only experience mild symptoms and will recover on their own. However, there are also sufferers who experience severe symptoms to appear complications, such as:

1. Respiratory disorders

The most frequent complications due to Corona virus infection are problems in the respiratory tract, such as respiratory failure or ARDS and pneumonia. This condition occurs when the lung tissue becomes inflamed and filled with fluid, which interferes with the respiratory process.

When experiencing these complications, sufferers of Corona virus infection can experience lack of oxygen. This is what makes many COVID-19 patients need breathing assistance, such as ventilator installation and oxygen administration.

2. Heart disorders

Corona virus infection can aggravate the work of the heart, making it dangerous for people who have a history of heart problems, such as heart disease and heart failure.

Some studies also show that the risk of death from COVID-19 is much higher in people who have a history of heart disease than in previously healthy people.

3. Kidney and liver disorders

Several case reports related to Corona virus infection mention that some patients with severe symptoms can experience liver failure and kidney dysfunction.

Until now, the cause of these complications is unknown. However, the body’s immune reaction to the Corona virus is thought to be one of the causes.

In addition to some of the complications above, sufferers of Corona virus infection are also at risk of developing sepsis. This condition is easier for COVID-19 patients who are weak and have been hospitalized for a long time.

A strong immune system is able to fight the Corona virus well so that the symptoms of COVID-19 that appear are mild and the disease can heal on its own. Conversely, if the immune system is unable to fight the Corona virus, severe COVID-19 symptoms can occur and there is a risk of complications.

Therefore, in addition to taking precautionary measures to prevent contracting the Corona virus, you also need to strengthen your immune system with a healthy diet and lifestyle.

If you have a fever accompanied by coughing or shortness of breath, especially if in the past 14 days you have been in a COVID-19 endemic area or have had contact with someone who is positive for the Corona virus, do self-isolation and call the COVID-19 hotline at 119 Ext. 9 to get further direction.
