Canada News – As countries begin to loosen the closures they imposed to counter the Corona pandemic and try to revive the economy, and with all the efforts made by doctors, scientists, and researchers around the world, there are still questions related to the virus, its impact on people, how it is transmitted, how it is infected, and what will happen in the days Coming.
In this context and to answer all questions, Rob Kozak told CTVNEWs.ca in a telephone interview on Thursday, a microbiologist at Sunnybrook Hospital in Toronto, who helped isolate the SARS virus in March, that people became aware of With the Coronavirus five months ago and there was not enough time to prepare for it.
He also indicated that they had started following up on people who might have contracted infection in January and recovered to find out what would happen with them.
According to the researchers, despite the desire of the isolated individuals to return to their normal lives, it may take several months to reach the answers to the questions.
Kozak mentioned 10 important questions about the Corona virus that have been asked by experts and have tried to answer them, as follows:
1. How many people are infected?
It is difficult to know how many people have already been exposed to the virus because some of them may be asymptomatic, or others may have mild symptoms without realizing that they are caused by the Corona virus.
According to Dr. Isaac Bogoch, an infectious disease physician and scientist at the Toronto General Hospital, this question can eventually be answered by using serum or blood tests for a specific population.
Once these tests are done, Bogoch expects a huge number of cases.
2. How do children transmit coronavirus infection?
While children appear to be less affected by the Coronavirus than older people, it remains unclear what role they play in transmitting the infection to others, noting that they still do not know whether children are infected, but stress that they are affected differently from adults.
According to Jude Uzonna, an immunologist and infectious disease researcher at Manitoba University, there is now evidence that children suffer from the widespread inflammatory response syndrome, which is similar to Kawasaki disease.
3. What is the severity of the disease?
Scientists are still trying to understand how the virus affects blood clotting in some patients, and the cause of loss of sense of smell or taste in some people.
He indicated that they are still in the stage of studying how the virus is linked to different parts of the body, such as brain cells and kidney cells.
According to Kozak, there is a lot of interest in knowing why some people are infected with the virus more than others. For example, if two people are infected with one virus, one can enter ICU and the other may not show symptoms.
4. Can people develop immunity to the virus?
Although there are many concepts such as herd immunity, which are based on the premise that people who contract the virus will not take the infection again, scientists still do not really know whether patients can develop a preventive immunity against the virus and if they can, for how long it will be A person is immune from infection again.
5. When does a person become infectious?
Scientists do not yet know when a person will become infectious, and Kozak noted that there are interesting data from Germany and the American Centers for Disease Control (CDC) indicating that people may not excrete the virus after about eight or nine days after symptoms appear.
He stressed that they need to conduct a lot of studies and a large number of patients to make sure that the patient is no longer contagious, but the problem lies in the patient’s test as he carries the DNA of the virus in his nose or throat.
6. How will the mutations affect the virus?
Kozak mentioned, there are studies claiming that the Coruna virus may mutate into more severe strains, but this is still not confirmed.
He said there may be mutations associated with either a worse disease or a milder disease.
Kozak indicated that these studies will benefit in the study mentioned previously related to the infection of some individuals more than others and whether this is related to an individual strain of the virus or hereditary predisposition, or a combination of these two factors.
7. Will there be complications after recovery?
Kozak said that patients with any disease often develop complications that last for months or even years after their recovery. After the Ebola outbreak in West Africa, the survivors suffered from rheumatic problems or eye diseases even after their recovery.
These questions have not been answered yet for the January study of people who were infected with the Corona virus.
8. Why are some areas more severely damaged than others?
According to Uzonna, many experts predicted that Africa would be destroyed due to insufficient infrastructure and health care, but that has not happened yet and Africa is not doing well so far compared to other countries.
He also indicated that he does not believe this is related to genetics because when looking at the United States, the majority of people who die are African Americans.
9. How do high temperatures affect the virus?
Because influenza is a seasonal disease that affects more people in colder months, some people have questioned whether the Corona virus will follow the same path and weaken in the summer, but Uzonna indicated that they do not know how high temperatures will affect the Corona virus because it differs from the virus That causes the common flu, and places like Ecuador, El Salvador and Bangladesh have all experienced severe outbreaks despite their warm climate.
10. Will the virus disappear forever?
While Bogoch and Kozak said, they are confident that scientists will be able to develop a vaccine to protect from the virus, but it is not yet clear how much protection it will provide and how long it will last.
Bogoch also wonders if the vaccine will be 100% protective, or it will be like the flu vaccine, that is, it will reduce the risk of infection with this infection only without eliminating the risk of infection with this infection.
And if people become infected, is there a possibility that the vaccine might reduce the severity of the infection or not.
It is worth noting that Uzonn, Bogoch and Kozak are all hopeful and optimistic in terms of reaching answers to all these questions, but we must be patient for a longer period until this epidemic is eliminated.
