What is the best situation that new coronavirus patients have to take to reduce the need to place them on ventilators, and what have we learned about the virus so far, and will life return to normal?

The answers in this report ...

During the six months that have passed since the start of the new coronavirus, SARS Cove 2, that causes Covid-19 رض, it has spread around the world, doctors have learned a lot in hospitals about how to treat people with the disease that can lead to death and result from infection with the virus.

What doctors have learned about Covid-19 is that people with the virus are more likely to develop strokes and that blood thinners can benefit patients.

Also, unlike the respiratory system and lungs, the Corona virus can attack many other parts of the body, including the heart, liver, kidneys, and brain.

One of the striking things that doctors have found is that sleeping on the stomach to relieve pressure on the lungs may eliminate the need to put patients on respiratory systems.

The best promising drugs so far appear to be:

  • Anti-viral remdisiver.
  • Dexamethasone, a steroid drug that treats infections in the body when infected with Covid-19.
  • Blood plasma donated by patients who have had antibodies due to HIV infection.

On the other hand, there are still some mysterious points, such as which drugs will achieve positive results with specific patients, and how long will the "Covid-19" patients need to recover, and what are the long-term effects of infection?

When did you first appear?

To date, scientists' data indicate that the first outbreak of the emerging corona virus was in December 2019 in China.

But a recent study, not published yet, found that the virus was present in wastewater in Barcelona, ​​Spain, in March 2019, a finding that, if confirmed, would show that the pathogen appeared much earlier than previously thought, according to a Karl report Zimmer and Raphael Minder in The New York Times.

"Barcelona is a city frequented by the Chinese people in the field of tourism and business, so maybe it happened elsewhere, and perhaps at the same time," said Albert Bush, lead author of the study, professor in the Department of Microbiology at the University of Barcelona.

Bush has been studying viruses in sewage for more than 40 years.

In contrast, independent experts who reviewed the results said they questioned the claim, and they confirmed that the study was flawed.

Several experts not participating in the research pointed to problems in the new study that has not yet been subject to critical review by external experts and that occurs before it is published in a scientific scientific journal.

Will life return to normal?

The two American scientists, Dr. Amitai Itzioni, Professor of International Affairs at George Washington University, and Dr. Ruth B. Itzioni, a biostatologist at the Fred Hutchinson Cancer Center, people dream that once they are vaccinated for Corona and become immune, they will once again be able to set off with thousands of other people to encourage their soccer team and invite as many people as they want to attend weddings and more.

The two scientists said in their report published by the American magazine "The National Interest" and reported by German news agency, that Bill Gates says that even "if our best treatments can reduce deaths by less than 95%, we will still need a vaccine before we return to our normal lives."

However, it must be borne in mind that even if the vaccine is proven to be effective and safe, it will take a long time before mass production and use due to the challenges posed by the production of billions of vaccines.

The two scientists say medical experts expect that "there will not be a sufficient vaccine for at least several years, even with the unprecedented effort to produce billions of doses. It is likely that there will be a need to vaccinate about 70% of the world's population, or 5 billion and 600 million people to start training." Herd immunity and slow the spread of the virus. "

For the vaccine to succeed, most people will have to agree to their vaccination. When the polio vaccine was produced in 1955, polio was eliminated in the United States. However, it continued until 1979 to ensure that there were no new cases of polio.

Around the world it took extraordinary efforts, supported by the World Health Organization and NGOs, to persuade people in developing countries of the safety of the vaccine and to persuade them to vaccinate. Polio remains a threat in some places.

Itzioni says that even if everyone in the world is vaccinated - a very huge task - we will not yet have the herd immunity to which we are looking, because many vaccines are not as effective as such immunity requires.

Herd immunity

Herd immunity requires that the population with immunity reaches 70 to 90% of the total population. For viruses such as influenza, vaccination was only effective in preventing 40 to 60% of the population from contracting influenza.

Finally, many viruses mutate any change in their genetic makeup. Some recent reports stated that the Corona virus is mutating, and if so, it may need a change in vaccines, depending on the type of mutation that we have.

Therefore, according to the report of the Worlds Itzioni, it is in any case better to realize that the Corona virus will stay with us for years and to accept the fact that living under various safety measures as well as testing and tracking contact, will still be with us even if vaccination is available on a large scale.
