In the shadow of omekron ... when is the end of the Corona epidemic?An expert answers Al -Jazeera Net

What are the most prominent data about the omearron breed of the Corona virus?Is it true that when the viruses are weakened?Does this apply to Corona?Under the Omekron Museum, is it possible to expect the end of the Kofid-19 in the world?Will we need fourth, fifth and sixth doses from the Corona vaccine?

We asked these questions to Dr. Muhammad Atta Handous Rahal, an assistant professor at Will Cornell College of Medicine, and a first consultant doctor, and holds the American Board, who answered it in statements to Al -Jazeera Net.

What are the most prominent data about the omearron breed of the Corona virus?

In 2020, the World Health Organization ranked the variables of the SARS-Cov-2 Corona virus (SARS-COV-a) to interesting variables and anxious variables, and used the Greek alphabet to name these types of variables to simplify matters.

The well -known variable variables include "AlphaB.1.1.7 (Alpha B.1.1.7) And "Beta B..1.351 "(beeta b.1.351) Gamma "B.1 "(Gamma P.1) And "Delta B.1.117.2 "(Delta b.1.117.a).

الآونة الأخيرة، تم تخصيص الحرف الـ15 من الأبجدية اليونانية أوميكرون للمتغير "بي .1.1.529 (B.1.1.529) which is currently in all regions of the world.

Recent studies have shown that the omekron variable is significantly transmitted, but fortunately, so far, the symptoms are more moderate compared to the Delta variable..

Moreover, omecarone does not significantly exceed the risk of infected in the inhabitant population.

Usually, a new variable appears concerned about the effectiveness of the vaccines currently used.These concerns can be correct, and preliminary studies have shown that the omecron variable may have the ability to partially evade the preventive features provided by the Kofid-19 vaccines..

Current studies have shown that those who received two doses of the Pfizer vaccine have a 25 -weak decrease in the ability to neutralize the infection towards the Omekron Museum compared to the original Corona virus.However, a reinforced dose (the third dose) of the Pfizer vaccine can provide protection of up to 80-95%.

In addition, 80% of the "Epitopes", which is part of an antigen recognized by the immune system of the virus that the TT cells "CD8 +T" known as memory cells are not affected by changes or mutationsIn omecron variable.

Is it true that when the viruses are weakened?Does this apply to omekron and Corona?

Viruses often mutate, especially those that contain Ribonucleic acid as a genetic substance, including the new Corn Virus and influenza virus.

When the virus spreads widely and causes the disease, the possibility of the virus mutates increases.The more chances of the virus spread, the more chances.A mistake in this transcription process leads to a boom.

Most viral mutations have a small or non -effect on the ability of the virus to exacerbate the disease.However, depending on the location of the mutations in the genetic material of the virus, it may affect the properties of the virus, such as the junction, the immune escape, or the transition.

The virus, which causes the Kofid-19, is covered with fatty membrane proteins (or sugary proteins) that can allow the virus to merge into the host cell membrane membrane. ويضم فيروس كورونا البروتين الشوكي "سبايك" (spike) ويقع على غلاف فيروس كورونا، وهو مصنوع من سلسلة خطية من حوالي1300 من الأحماض الأمينية.

Changes, especially those related to spinal protein, are the main cause of the boom in the virus that causes the Kofid-19 virus.

Under the Omekron Museum, when do you expect the Kofid Kofid in the world?

It is difficult to predict or set a date for the end of the Kofid-19 in the world, so the paths of the pandemic and their possibilities are dependent on the way societies interact.

However, we have strong evidence that the reinforced Kofid-19 vaccine doses can increase protection against Kovid-19 including the omecron variable.

Moreover, there are currently some effective oral treatments that reduce the severity of the disease.

Also, we learned, the last two years of the epidemic, that following some precautions and health measures can be decisive in reducing the transmission of infection, and thus the epidemic.

ماذا عن سلالة كورونا "بي1.640.2 "that appeared in France?

أبلغ علماء فرنسيون مؤخرا عن حدوث تغييرات بالفيروس لدى12 مريضا مصابا بفيروس سارس يعيشون جنوب شرق فرنسا.The first case that was identified or the case of Cameroon to France traveled.The same researchers found at least 46 booms in the virus, including many mutations in Spike protein.The variable was named (B.1.640.a) أو "آي إتش يو" (IHU) لأنه تم اكتشافه في معهد البحر المتوسط للأمراض المعدية (institute Mediterranean Infection) (IHU) في فرنسا.

It may be difficult at this stage to consider the variable a new boom, especially as the mother line (Parent Lineage).1.640 "(b.1.640) It was reported in November 2021 in Ghana.

هل سلالة كورونا "بي1.640.2 "threaten new epidemic and more injuries?

من المبكر جدا توقع أن المتغير "بي1.640.2 "It can be more disturbing or move faster.It should be remembered that most viral mutations have a little or no effect on the ability of the virus to exacerbate the disease.However, the monitoring of this alternative is justified.

What tips do you give to the Arab public?

Stopping from the source and immunization is still very important.Receiving a reinforced dose will increase immunity against omecron.The precautions used regularly must be followed since the beginning of the epidemic.These procedures include physical spacing, avoiding closed places or crowding, wearing a face mask or face condom, and cleaning hands frequently.By reducing the amount of virus's ability, the possibility of a new variable appears is low.

Do you expect fourth, fifth and sixth doses from the Corona vaccine?

Protection against Coveyd -19 diminishes with time, which is why reinforcements are provided.More studies are needed after the stimulant of immunity control, and the impact of more doses will be determined at the level of this protection.

5 Bechara about omecron and Corona

And the past days carried promising indicators about the Kofid-19 pandemic, which included:

1- More evidence that the symptoms of omekron are lighter

A World Health Organization official said on Tuesday that more evidence shows that the protruding Omekron breed of the Corona virus affects the upper respiratory system and causes lighter symptoms than previous museums, according to Reuters..

"We see more and more studies that indicate that omecron affects the upper part of the body.Unlike other mutations that can cause acute pulmonary inflammation..He continued that this may be "good news".

However, he said that the speed of the spread of omecron means that it will be the prevailing museum in many places within weeks, which poses a threat in countries whose large number of residents have not been vaccinated yet..

His remarks agree on the decline in the risk of developing the disease with other data that includes a study from South Africa, which is one of the first countries to monitor the omekron..

2- The French Minister of Health is optimistic

"This fifth wave may be the last," said French Health Minister Olivier Ferran..

The minister reiterated his statements to France Inter on Monday with some caution, saying, "Everything is about.Probably".

3- The beginning of development towards a more common virus

Alan Fischer, in charge of the French vaccination program for the BFMTV channel on Monday, announced that with a new mutant "more transmission (than its predecessors, but less dangerous), we may witness the beginning of development towards a more common virus similar to other viruses".

In other words, a virus is more infected and less dangerous that would allow natural immunity in addition to the immunity given by the vaccine, which means entering at a less dangerous stage than the epidemic.

4- Corona will join the viruses that cause colds

And at the end of the week, French epidemic Arno Fontene announced, "In the end there is hope..Corona will join other seasonal human coronary viruses that cause colds and tonsillitis every winter..

He said, "We have not reached this stage yet.We can expect new museums, but because of strengthening our immunity over time, either through natural infection or reversed doses, its ability to cause serious situations will decline. ".

5- It is not the last, but what comes after it is weaker

On Sunday, Professor Eric Com announced the former head of the Infectious Diseases Department at Betier Salbetiar Hospital in Paris, "I am convinced that this wave will not be the last.".

He added, "But it may be the last of this strength.".
