Coronavirus is losing its infectivity and will be over before a vaccine arrives, some doctors feel!

COVID-19 has caused a rampage on this planet since December 2019. The cases continue to rise globally. But we have an infectious disease specialist from Italy who claims that the viral potency is declining. He feels that the virulence of the coronavirus will die out soon without the need of a vaccine. Not all agree with his point of view? Is there any scientific proof of the weakening virulence of coronavirus?

An Italian doctor – Coronavirus  is weakening!

More than 9 million people worldwide had coronavirus afflictions. Deaths run in hundreds of thousands. Pharmaceutical companies are trying rapidly to come out with a safe and effective vaccine for this deadly 21st century disease. But Dr. Matteo Bassetti, head of the infectious diseases clinic at Italy’s Policlinico San Martino Hospital, states that the need for a vaccine against coronavirus may not arise at all. He feels that the virus is losing its strength due to genetic mutations.

Matteo told The Telegraph:

The clinical impression I have is that the virus is changing in severity,”

Matteo’s explanation about coronavirus

Dr. Matteo elaborated:

“In March and early April, the patterns were completely different. People were coming to the emergency department with a very difficult-to-manage illness, and they needed oxygen and ventilation; some developed pneumonia.

“Now, in the past four weeks, the picture has completely changed in terms of patterns. There could be a lower viral load in the respiratory tract, probably due to a genetic mutation in the virus which has not yet been demonstrated scientifically. Also, we are now more aware of the disease and able to manage it,”

He added:

“It was like an aggressive tiger in March and April, but now it’s like a wild cat. Even elderly patients, aged 80 or 90, are now sitting up in bed, and they are breathing without help. The same patients would have died in two or three days before,”

He attributes this weakening to genetic mutations and added benefit of social distancing and mask-wearing. Furthermore, Matteo said:

“Yes, probably it could go away completely without a vaccine. We have fewer and fewer people infected and it could end up with the virus dying out.”

Prof. Karol Sikora, an oncologist and the chief medical officer at Rutherford Health had in this May noted similar observations.

Some scientists disagree…

Not all are in agreement with these points. Many feel that there is still a long way to go. Dr. Bharat Pankhania, a senior clinical lecturer at the University of Exeter Medical School and a former Public Health England consultant feels that one has to be optimistic but the truth is that the virus is here to stay longer, he said. He added:

It will if it has no one to infect. If we have a successful vaccine then we’ll be able to do what we did with smallpox. But because it’s so infectious and widespread, it won’t go away for a very long time,”

“My estimate is ranging from ‘never’ to – if we are really lucky and it sort of mutates and mutates [and] may lose its virulence – we’re talking years and years,”
