Which body part does the corona virus affect? How damaging can the consequences of covid-19 on the human body be?
When infected with covid-19 , the body will show signs of damage to the central nervous system such as dizziness, headache, decreased consciousness, seizures and stroke. Chinese news agencies have also reported that doctors in this country have proven the SARS-CoV-2 virus can damage the central nervous system of patients.
In fact, researchers have also found that the viruses that cause SARS and MERS can enter the nervous system of patients, so it is not too surprising that the virus that causes covid-19 is similar.
Cough is the most prominent manifestation of covid-19, in addition to shortness of breath and severe pneumonia. For most patients, covid-19 begins and ends in the lungs, due to the fact that the corona virus family mainly causes respiratory disease. Infection starts when an infected person coughs or sneezes, splashes liquid droplets containing the virus to nearby people.
The initial symptoms of corona virus infection are similar to those of the common flu: the patient may develop a fever, cough, and then continue to progress to pneumonia or get worse.
The disease usually attacks the lungs in three stages: viral replication, proliferation of the immune response, and ultimately lung damage:
In the early days of infection, the virus attacks heavily on lung cells, mainly the layer of cilia cells that protect the mucosal cells (mucous membranes).
Before the invasion of the virus, the body responds by boosting immune cells to the lungs to repair damage. If functioning properly, this inflammatory process is controlled and limited only to the infected part. But sometimes the immune cells get over-stimulated, killing them all along the way, irrespective of virus or healthy tissue.
At stage 3, lung damage continues to spread, possibly leading to respiratory failure . In the absence of death, the patient is still more likely to suffer permanent lung damage with the characteristic "honeycomb" lung scan. At that time, the patient often needs to use a breathing machine to support breathing.
Gastrointestinal problems such as diarrhea, vomiting and abdominal pain are among the main symptoms in patients with viral infections. Research by scientists shows that the corona virus exists in human feces, a sign that this may also be the source of transmission, although not certain.
Kidney damage has been reported in patients with an alarming proportion of those requiring dialysis. Virus has been found in the patient's kidney tubules, which can cause inflammation.
When the virus spreads from the respiratory system, the liver is usually the last organ to damage. Signs of liver damage seen in covid-19 cases are usually mild, but there are cases of more serious liver damage, even liver failure.
Besides irregular heartbeat, corona virus can lead to cardiac arrest, the heart does not pump enough blood to the tissues, causing low blood pressure in infected people.
Due to an over-immune response, the SARS-CoV-2 virus can also cause problems in other systems of the body. In fact, all three strains of the virus that cause SARS, MERS and COVID-19 have systemic effects: elevated liver enzymes, decreased white blood cells and platelets, and low blood pressure. In rare cases, patients suffered from acute kidney damage and cardiac arrest. In addition, coronavirus also affects many other organs in the body such as:
Eyes: The virus can cause eye redness, redness or conjunctivitis in some patients.
2 legs: 1 strange symptom associated with this virus is purple leg ulcers, also known as "covid toes".
Sensory nervous system: Loss of taste and smell
Blood: SARS-CoV-2 makes the blood thicker, creating a blood clot in the vein. The clot can rupture and travel to the brain and lungs, causing an obstruction.
