Coronavirus: what scientists have learned so far
A new strain of coronavirus – SARS-CoV-2 – was first discovered in December 2019 in Wuhan, a city in the Chinese province of Hubei with a population of 11 million, after an outbreak of pneumonia for no apparent reason, the virus has now spread to more than 200 countries and territories around the world, and the World Health Organization (WHO) described it as a pandemic on March 11
As of November 23, 2020, there were 58,229,138 laboratory-confirmed cases of coronavirus disease 2019 (COVID-19) globally, with 1,382,106 deaths reported, the number of cases and deaths outside China exceeded those within the country on March 16, 2020 .
Much is still unknown about the virus, including how many people may have a very mild or asymptomatic infection, and whether they can transmit the virus, it is difficult to know the exact dimensions of the outbreak, the more time passes, the more data we collect, the more evidence and conclusions we can make, however, it is important to remember that this is a new virus,
What is coronavirus?
Coronavirus disease (covid-19) is an infectious disease caused by a newly discovered coronavirus, coronavirus is a species of virus that infects animals. Occasionally, it is known that coronavirus is transmitted from animals to humans, the coronavirus we are talking about today is a new virus that causes a disease called COVID-19, through droplets of saliva or secretions from the nose when the infected person coughs or during sneezing .
How dangerous is it?
It is difficult to accurately assess how dangerous this new virus is, it seems to be less dangerous than the coronavirus that caused SARS or Middle East Respiratory Syndrome, but it is more dangerous than seasonal flu, the mortality rate was more than 2 percent, in one study, but scientists estimated that the real figure may be less than 1 percent, which is the rate
Children seem to be less likely to be infected with the new coronavirus, while middle-aged and older adults are disproportionately infected, men are more likely to die from infection than women .
When will this epidemic?
Throughout these months, with more than 37 million cases of COVID-19 and more than a million deaths globally, you may wonder, with increasing indignation, How long this will last.
In the early days of the epidemic, many people hoped that the coronavirus would simply disappear, some argued that it would disappear on its own with the summer heat, others claimed that herd immunity would take off as soon as enough people were infected, but none of this has happened, since the beginning of the epidemic, epidemiologists and public health specialists use mathematical models
A combination of public health efforts to contain and mitigate the epidemic – from rigorous testing and contact tracking to social distancing and wearing masks-has proven to help prevent infection, and given that the virus has spread almost everywhere in the world, such actions alone cannot end the epidemic, attention is now turning to the development of the vaccine, which is
However, experts tell us that even with a successful vaccine and effective treatment, COVID-19 may never disappear, even if the epidemic is curbed in one part of the world, it is likely to continue elsewhere, causing infection elsewhere.
Finally, the best way to prevent and slow transmission is to be well aware of the COVID-19 virus, the disease it causes and how it spreads, protect yourself and others from infection by washing your hands or using an alcoholic disinfectant frequently and not touching your face.
Where did this virus?
SARS-CoV-2 belongs to a family of single-chain RNA viruses known as Coronaviridae, a common type of virus that infects mammals, birds and reptiles .
It is currently unclear where the virus came from, originally, it was understood that the virus originated in the food market in Wuhan and subsequently spread from animal to human, some research has claimed that cross-species transmission may be between Snake and human, however, this claim has been challenged, mammals such as camels and bats have been involved in
Since this coronavirus affects the respiratory system, the common symptoms include fever, dry cough, with some patients, respiratory symptoms (such as sore throat, nasal congestion, malaise, headache and muscular pain) or even difficulty breathing.
In humans, it usually causes mild infections, similar to colds, and accounts for 10-30% of upper respiratory tract infections in adults, more serious infections are rare, although coronavirus can cause intestinal and neurological diseases, the incubation period of coronavirus varies but is generally up to two weeks .
Men are more susceptible to infection than women probably because they produce weaker immune responses and have higher rates of tobacco consumption, type 2 diabetes and high blood pressure than women, which may increase the risk of complications after infection.
In severe cases, coronavirus can cause pneumonia, acute respiratory syndrome, kidney failure and death, the diagnosis is suspected in patients with a new and persistent cough, fever, loss or change in the sense of smell or normal taste, a diagnostic test has been developed, and countries are imposing quarantine on suspected cases .
Those who have a new and persistent cough, high fever or loss of sense of smell, and who live alone should isolate themselves for 10 days from the onset of symptoms, all households should isolate themselves for 14 days if one of their members shows symptoms .
