Will the corona virus no longer survive?

WASHINGTON: Medical experts have launched an investigation into whether the new Corona virus is as deadly as it used to be, following observations and studies of the world’s deadliest corona virus.

Mortality rates have dropped significantly in places around the world that have been the epicenter of the corona virus, and although the rate of infection has risen during the new wave of corona epidemics, scientists are confident that it Change is real, but its causes and persistence are still being debated.

“Whether it’s a phenomenon or a temporary one, no one knows,” said Joshua Barrox, an epidemiologist at the Boston University School of Medicine. Because since the beginning of this epidemic, its mortality rate has been fluctuating.

In this context, Syed Al-Zain, who worked for three consecutive months at the Detroit Medical Center in the US state of Michigan, noticed that patients with coronavirus are no longer sicker than in the previous months in May. Interestingly, Ciara P. Bailey, a female researcher from northern Italy, more than 4,000 miles away, came to the same conclusion. Raphael Canton, a Spanish epidemiologist, also saw the change.

According to initial reports from China, the death toll from the corona virus was up to 7%, but the rate was mostly based on hospitalized patients. When the wave reached the United States, epidemiologists thought it was 2%. To 3%. Now the rate is 0.65 percent, according to the US Centers for Disease Control and Prevention (CDC).

Joshua Barrocks insists that millions of deaths are possible despite low estimates, as the United States currently has the highest rate of coronavirus cases in the world and the death toll is higher than in any other country. 20% of

Public health officials point to a number of reasons for the decline in mortality, as young people are becoming more vulnerable and their immune system helps them recover. Extensive testing has led to early diagnosis of cases and improved treatment strategies.

Preliminary research suggests that a portion of the population is already partially immune to the corona virus, possibly due to the corona viruses that cause the common cold or childhood vaccinations or some other reason. ۔ Another important possibility is that our environment has changed, ie the weather, behavior or the virus itself.

Experts say that the lethality of most viruses gradually decreases due to various reasons such as lack of hosts, changes in the virus that make it less lethal, new treatments or vaccines. According to experts, the same will happen with the new Corona virus, but it remains to be seen how long it will last and how many more deaths have occurred. However, the role of social distance and face masks was also appreciated.

Another point that medical experts have discovered is that corona’s viral load (a measure of the amount of virus in the body) has changed dramatically over time, according to Monica Gandhi, an epidemiologist at the University of California, Los Angeles. Expressing his views, he said that if the initial viral load is low, it is likely that people’s bodies will be able to fight it more effectively.

He said that this indicates that the ability to prevent viral infections has improved and as a result, its severity in people has decreased.

The second wave

Early reports of a decrease in the severity of the corona virus surfaced in late May and were met with considerable skepticism.

Dr. Alberto Zingarello, head of the San Refaeli Hospital in Milan, Italy, said in an interview on May 31 that the fact is that the virus is no longer medically present in Italy. He said that the viral load seen in the swab test during the last 10 days was not as high as it was a month or two ago.

He said that the second wave was from May 16 to July 7 in which less number than the first i.e. 20% required ICU while the first wave from March 13 to May 15 affected 38% of the patients. Was admitted to the ICU.

Similarly, second-wave patients spent less time in hospital, which was 4.8 days, compared to an average of 7.1 days for first-wave patients. But most importantly, the second-wave death rate was 5.1%, while the first-wave death rate was 12.1%.
