The speaker, Professor Jubilo, explains the process of how the coronavirus infects the human body and causes COVID-19. He begins by describing how the virus is transmitted through droplets of saliva that are released when an infected person talks, coughs, or sneezes. These droplets can land on surfaces and be transferred to others through touch.
Once the virus enters the body, it attacks the cells lining the nasal passages, throat, and lungs, causing inflammation and damage. The virus hijacks the cell's machinery to produce more viruses, which can lead to pneumonia and other complications.
Professor Jubilo explains that the immune system's response to the virus can sometimes be too strong, causing more harm than good. In severe cases, the virus can cause the lungs to fill with fluid, leading to respiratory failure and even death.
He also notes that the virus can affect other parts of the body, such as the heart, kidneys, and liver, and may even be able to reach the brain. However, he emphasizes that most people (around 80%) who contract the virus will not experience severe symptoms and will recover on their own.
The professor stresses the importance of washing hands, avoiding crowds, and being "antisocial" to prevent the spread of the virus. He also notes that there is currently no vaccine or medicine to prevent or treat COVID-19, but supportive treatment can help alleviate symptoms.
Finally, he encourages viewers to stay informed and to appreciate the efforts of healthcare professionals and educators who are working to combat the pandemic.
1. The speaker is discussing the spread of the coronavirus.
2. The virus spreads through droplets of saliva, which can be transmitted through coughing, sneezing, or speaking.
3. These droplets can fall on surfaces and transmit the virus through direct contact or indirect contact, such as touching a surface and then touching your mouth.
4. The virus can also contaminate objects like cell phones, door handles, and computer keyboards.
5. The primary target of the coronavirus is the respiratory system, specifically the cells lining the nasal passages, throat, and lungs.
6. The virus causes inflammation and damage to these cells, which leads to the production of more viruses and the release of these new viruses into the body.
7. The virus can cause symptoms like a dry cough, sore throat, and loss of smell.
8. The virus can also cause inflammation and damage to blood vessels, the heart, kidneys, and liver.
9. There is a suspicion that the virus can reach brain cells, but this is not yet confirmed.
10. Around 80% of people infected by the coronavirus will not present severe symptoms, and their immune system will manage to destroy the virus before it causes serious damage.
11. Around 20% of people infected by the coronavirus will present more severe symptoms and may require hospital care.
12. Around 1% of infected people will die from the disease.
13. Even if you have mild symptoms or no symptoms at all, you can still transmit the virus to others.
14. There is currently no vaccine or medicine for the disease caused by the coronavirus.
15. Supportive treatment is used to prevent the accumulation of fluid in the lungs and allow the patient to breathe.
16. The speaker advises washing hands, avoiding crowds, and staying informed about the disease.
17. The speaker concludes by emphasizing that the situation is dynamic and new information about the virus can emerge at any time.
