Coronavirus: 4 Deathful Damages to Body By COVID-19
The latest Coronavirus confirmed grow up to 2,256,844 in the world, and deaths goes to 154,350. And in US, the confirmed increased a lot to 712,184 till 18th, April. And the number is increasing a lot every day. Even though Trump announced the “3-steps” reopen plan, no one knows when epidemic will end. Coronavirus has been confirmed in more than 210 countries and regions. It is a global panic to the world.
Since Coronavirus is not able to be defeated, and will keep spread in the world for long, some knowledge of COVID-19 must be known to every one. How does Coronavirus damage the body? Then we may know the important and dangerous of COVID-19, and to take property action to protect self.
Attach Respiratory System
As reported, the oronavirus pneumonia patients with symptoms of coughing, persistent fever, and unexplained fatigue, small white irregular patches may appear on their lung CT. A long with the continuous “attack”, the infection becomes worse and worse. The white consolidation nodules begin to be absorbed, and “lesions” like cloud-shaped frosted glass appear in some parts of the lung. It is medically known as “ground glass shadow”. And more seriously, the patient will have difficulty breathing.
If the virus replicates in a large amount, or the patient’s immune function is weak, the virus will attack multiple lung lobes, the alveolar damage is diffuse, the lesion range expands and merges, resulting in consolidation of both lungs. It is white and is called “white lung” in medicine. This situation will seriously affect lung ventilation, and patients need continuous oxygen inhalation. “White lung” is the main manifestation of critically ill patients. In patients who have progressed to this time, lung ventilation is severely affected, requiring continuous oxygen inhalation, ventilator, and even extracorporeal membrane oxygenation (ECMO). If the treatment is not timely, the person infected with the new coronavirus is like drowning and has difficulty breathing until death.

Damage Immune System
The general route of the Coronavirus spread in the human body: Nasal cavity - Oral cavity - Throat - Trachea - Bronchus - Bronchioles - Alveoli. In the whole invading process, the immune cells of the immune system are fight against the virus at all parts to protect the body to be invaded.
The virus enters the nasal cavity, the immune cells sound an alarm, and stimulate the nerve endings of the nasal mucosa, so they start sneezing. Viruses that have not been expelled will invade the throat due to the fine force generated by inhalation, allowing immune cells to directly engulf the virus or be activated, thereby suppressing and attacking the virus. Some viruses break through the defense of the throat, enter the trachea and bronchus, and the immune cells release factors to promote the secretion of mucus on the airway surface cells, wrap the bacteria, and rely on the cilia on the airway surface to push up and push these mucus out of the mouth At this time, a dry cough appeared. When the virus breaks through the trachea and bronchi and invades the alveoli, the immune cells in the alveolar area will also be activated, releasing cytokines and directly stimulating the body’s temperature regulation center, which will cause the body to heat up. In addition, after the virus invades the alveoli, if it causes a large number of epithelial cell deaths, it may appear as a persistent high fever and fever reaction. In fact, it also belongs to a protective mechanism of the body. Some viruses enter the digestive tract through the throat, infect intestinal epithelial cells, and activate the intestinal immune response, causing some people to experience gastrointestinal symptoms such as diarrhea.
When Coronavirus wins the “war” with the immune system, the body gets infected and damaged. The immune system of the human body is greatly damaged, then drugs and auxiliary treatments have to be used to fight against Coronavirus.
Injure Reproductive System
A new study from the National Institutes of Health (NIH) declared that the male fertility catastrophe is coming. NIH research believes that testis are highly susceptible to Coronaviruses and the growth of sperm could be disrupted. Coronavirus will destroy the internal structure of the male testis, leading to erectile dysfunction, and infected people will have impotence, so the COVID-19 patients should be tested for fertility after being cured and discharged from the hospital. Meanwhile, doctors also found that Coronavirus can cause 3% -10% of patients’ kidney damage.
Invade Digestive and Blood Circulation System
Coronavirus could invade cells by spiking glycoprotein (S protein) and integrating angiotensin converting enzyme 2 (ACE2), and then causing tissue damage. In addition to the lungs, many other organs in the body also express ACE2, such as testis, small intestine, kidneys, heart, and thyroid. Especially during the accelerated phase of severe critical illness, the virus not only damages the lungs, but also damages the outside of the lungs such as the heart, kidneys, liver, and blood system.
Knowing how Coronaviurs goes into the body, and how it damages the body, people would have more confidence and know how to protect himself/herself, and the others loved. Coronaviurs is dangerous, right protective preparation are also required. It is not the time to reopen in fact.
