What does Corona do to the body? We go through this on a journey from the throat to the lungs to the heart to the kidneys.
Some people only feel a slight cold or don’t feel anything at all, others are confined to bed for weeks: Corona can do a wide variety of things to our bodies – and is more than just a lung disease. The virus has these effects from head to toe, from brain to kidney.
What does Corona do to the body? Starts in the nose and throat
Whether speaking, sneezing, breathing, coughing or singing: virus-containing aerosols are responsible for the coronavirus being transmitted between people in the first place. So it basically travels from mouth to mouth – as the virus-containing droplets dock in the nose and throat. This is where the viruses multiply and inflame the upper respiratory tract. Cough, sore throat and loss of taste (rare with Omicron) are corona symptoms. For many infected people, these milder symptoms remain. According to the RKI, this is 80 percent of the diseases. But in some cases, the virus continues to travel – and can cause damage throughout the body.
This is what Corona does to the lungs
The viruses do not stop in the throat, but attack the deeper respiratory tract and the Lunge over, this can trigger pneumonia and even lead to lung failure. The virus attacks the lungs in three phases: It multiplies there, then causes a strong immune reaction and finally destroys the lung tissue. The irritated lung wall causes coughing. The alveoli can no longer absorb oxygen. Patients suffer from shortness of breath. 25 percent of SARS patients suffer from this.

So if the virus travels deeper into the lungs, you can feel it too: you no longer just feel slightly cold, but really sick. Shortness of breath, cough and fever also occur. This particularly affects older people and risk groups who are not as resistant to the virus. But younger people also suffer from severe cases like these.
Corona causes this damage to the heart
For some people, the virus does not stop in the lungs but spreads further throughout the body. For example, sick people suffer more often from thrombosis, i.e. Bluger islands. And that can be dangerous for everyone: the clots are transported throughout the body in the blood. They can cause an embolism in the lungs, a stroke in the brain and a heart attack.
The Herz is particularly at risk anyway. Infected people are more prone to inflammation of the heart muscle and cardiac arrhythmias. Scientists have managed to detect coronaviruses in the heart.

This is what Corona does to the brain
But the virus doesn’t stop here either. The small virus can also occur in… Brain cause immense damage, at least indirectly. This is particularly noticeable in severe cases: the overreaction of the immune system can also trigger inflammation in the brain and spinal cord. This can lead to memory problems, confusion, difficulty concentrating and epileptic seizures. In addition, the lack of oxygen in severe cases damages the brain. These, as we now know following two and a half years, can last for months: Long Covid.
This is how the nervous system suffers from Corona
This can be complete Nervous system be affected by the virus. This can lead to paralysis in the part that lies outside the brain (peripheral nervous system). This so-called Guillain-Barré syndrome is already known from other diseases such as other viral lung infections and bacterial gastrointestinal infections.
Corona in the stomach: The kidney and the intestine
Although Corona is a lung disease, the virus can also cause damage to the abdominal cavity – especially in the Kidneys. It is the second most commonly affected organ in a severe corona infection. 27 percent of all ventilated patients suffer from kidney failure. Some of the viruses are found in the kidneys and can also multiply there. The liver and digestive system can also be affected.
A quarter of those infected also suffered from diarrhea. Because ours Colon is very sensitive and a gateway for viruses.
Long Covid: symptoms and duration
Every infection is just as individual as every body is. Some suffer violently and for a long time, others don’t even notice that they are carrying the viruses. An estimated 40 percent of those infected have such an asymptomatic course. But a full ten percent are not there following a few days: they are suffering from Long Covid.
The most common Long Covid symptoms include:
- Exhaustion (58 percent)
- Headache (44 percent)
- Difficulty concentrating (27 percent)
- Hair loss (25 percent)
- Shortness of breath (24 percent)
- Loss of smell and taste (23 percent)
With Long Covid, symptoms can still occur weeks following infection. A fifth of all those infected were still affected following more than a year. And the longer the symptoms last, the less likely they are to go away on their own. The exact effects and long-term consequences are quite unexplored. Therefore, anyone who experiences symptoms for longer than average should see a doctor immediately.
