The past few days carried a wide range of good news about controlling the epidemic of the emerging coronavirus "SARS Cove 2" that causes Covid 19, including progress in reducing mortality, saving millions of lives, scientists understanding the virus more, and developing sterilization methods to eliminate it.

We start with a new study by Italian universities and local public health authorities, and found that the Corona virus has become less lethal over the past few months. Although there is no evidence to show that genetic mutations have contributed to reducing the risk of the virus, treatments have improved dramatically, according to the report published by the Wall Street Journal.

The newspaper pointed out that the doctors noticed a decrease in the death rate due to the Corona virus significantly since the beginning of the epidemic, and that the study conducted to compare the death rate in Ferrara and Pescara in Italy over March and April is the first to confirm this conclusion.

Significant drop

The study found that the overall death rate fell by about 40% from March to April, with a significant decrease in the over-80s age group (from 36.3% to 16.1%) and people with high blood pressure (23% to 12.1%), diabetes patients (30.3% to 8.4%), cardiovascular patients (31.5% to 12.1%), chronic obstructive pulmonary patients (29.7% to 11.4%), and kidney disease (32.3% to 11.5%).

The researchers say their study confirms that early management of appropriate medications significantly improves the clinical course of Covid-19 disease.

Doctors use a combination of treatments for Corona, including HIV, anticoagulants, and antibodies such as tocilizumab.

The Wall Street Journal concluded that as treatment progresses, if a second wave of Covid-19 disease appears, it is likely to be less lethal than the first wave.

Save 3 million lives

In Europe, researchers said today, Monday, that widespread public isolation measures that include the closure of shops and schools have reduced transmission rates of the emerging corona virus in Europe enough to control its spread, and may have prevented the deaths of more than three million people.

Scientists from Imperial College London said - in their model-based study of the impact of closures in 11 countries - that the tougher steps taken most of them in March had led to a "material impact" and helped bring the number of infections to less than one by early May / May.

This, known as the R number, measures the average number of people with whom the disease is transmitted from one person who has the infection. Increasing this number to one may lead to what is known as the exponential growth of the disease.

Another study prepared by scientists in the United States, published alongside the study of the Imperial College team in the journal Nature, concluded that the general isolation policies imposed in China, South Korea, Italy, Iran, France and the United States prevented or delayed the infection of about 530 million people.

Decode a new puzzle

A recent study found that people who have a blood type (A) need during their treatment of corona disease twice the amount of oxygen, and that they are more in need of artificial respirators compared to those who have a blood type or (O).

As for the rest of the blood types (AB) and B (B), the severity of the symptoms of the disease in their owners ranges between these two groups in a different way, as the German website NTV quotes from the study.

The importance of the study lies in the fact that it may help in predicting the course of the disease based on the blood group of the person, which makes doctors able to provide intensive treatment early for the cases that are expected to be more difficult, which helps in the non-development of serious complications and death.

The study was conducted by a German-Norwegian team of researchers led by Tom Karlsen from the University Hospital in Oslo, and Andre Frank from the University of Kiel, Germany, and included obtaining 2205 blood samples from healthy people from both countries to compare with those who suffered from corona disease, and also transmits the NTV German.

It is reported that Chinese researchers had previously reached a similar conclusion earlier, but the results of their study have not been confirmed. However, the research team from Germany and Norway indicated that the results of their study have not yet been subject to what is called "peer review" and in the research world it means a work evaluation process carried out by a person competent and competent by specialists in the same field.

UV sterilization

And we conclude from Russia, which is developing a treatment against the emerging corona virus, which works by sterilizing the body from the inside with ultraviolet radiation, according to a report published in the American magazine Newsweek.

In her magazine report, writer Hanna Osborne attributes it to Andrei Goverovovsky from the State Nuclear Agency Rosatom to say that scientists in Russia are developing a cure for the Corona virus with this technology.

In an interview with the Country Newsletter, Goverdovsky said, experts at the Institute of Physics and Energy Engineering are currently developing methods to fight viruses, including SARS Cove 2, which causes Covid-19 disease.

He said they named the project "luminous gas", but they had not yet succeeded in loading an ultraviolet disinfectant into a human body.

"We have discovered how to do this. We choose the particles and gas components that are inhaled, and when inhaled they emit ultraviolet radiation directly into the lungs," he explained.

Goverovovsky said he hoped to use this technology to treat tuberculosis and oncology in addition to Corona.

The author concluded that no further details were available on how the technology works and what tests were performed as part of the project.
