Simple steps can partially protect you from corona, at a time when the possibility of a receding virus is not imminent, and scientists avoid the direct answer to the question that everyone asks: When does the Corona virus end?What started as a handful of mysterious diseases in vast China is now traveling all over the world, jumping from animals to humans, and moving from mystery to world news headlines.
The Coruna virus, which was detected in the last month of 2019, infected tens of thousands of people, both inside and outside the Chinese border, and killed more than 2,500 people. It caused unprecedented quarantine measures, stock market turmoil, and the emergence of dangerous conspiracy theories.
Most cases are mild, but health officials say the spread of the virus in the United States appears unavoidable. As the country prepares and its health system, we still do not know much about what is now called the new coronavirus or covid-19, according to a report by the Washington Post.
The Washington Post has spoken to various sources of doctors, officials, and experts so that they can answer as many questions as possible about the most recent medical emergency in the world. Here’s what we know so far.
What is this virus? What are its symptoms?
Nowadays the name of the Corona virus is usually followed by the word “new” because this is exactly what it is, it is a new branch of a family of viruses that we have all seen, and may have infected us in some way. According to the World Health Organization, coronaviruses are a large family of viruses, starting from a common cold and reaching far more serious diseases. These diseases can affect both humans and animals.
This new branch, which is beginning to spread in Wuhan, the capital of China’s Hubei Province, is linked to two other types of corona viruses that have caused major outbreaks in recent years: severe acute respiratory syndrome (SARS) and respiratory Mediterranean syndrome (MERS).
The symptoms of corona virus infection range from respiratory problems to pneumonia, kidney failure and fluid build-up in the lung.
How deadly is this disease? Are the numbers of injured people greater than announced?
The good news is that health officials say the new coronavirus is less deadly than SARS, which killed more than 10% of those infected with it during the outbreak that started in 2002. But the burning question remains: How deadly is this disease?
In February, 2% of the infected cases died, but many experts say the death rate may be lower. This is because at the beginning of the outbreak, light cases may not have been recorded. If only people with severe symptoms, who are more likely to die, are seeking care, then the virus appears to be far more deadly than it really is, given all the less symptomatic cases.
At the start of the outbreak, an expert estimated that although there were 2,000 recorded cases, there are probably around 100,000 people already infected.
How easy is it to spread? Can he move from a person before symptoms appear?
The bad news is that experts say the new Corona virus is spreading much faster than SARS, and its symptoms are similar to other Corona viruses that cause symptoms similar to the common cold.
A virus that can spread easily, and may have already spread greatly, is a major public health challenge.
It turned out that the recorded case indicating that the disease might spread without symptoms is incorrect, but a senior official said he still believed he could spread without symptoms based on discussions with Chinese experts.
“In SARS it seemed that people were kind of sick before they started transmitting the disease, and that’s why, in my view, they managed to control SARS,” said Mark Lipsic, an epidemiologist at Harvard Chan School of Public Health. “You can really isolate the people who are sick,” he added.
Who is most vulnerable to severe disease?
Like other respiratory diseases, the elderly are more likely, and patients with diseases such as diabetes and high blood pressure. Early studies indicated that men were at greater risk.
However, as with other diseases, there can be huge individual differences in how people respond. There will be people with factors that increase the severity of the disease for them and at the same time recover, as well as people who reach advanced stages of the disease for reasons that we do not understand.
“Maybe it is something very specific that has to do with the way your immune system interacts with a particular pathogen,” said Alison McGuire, an epidemiologist and infectious disease at the University of Toronto. He added, “It may also be related to what you have been through.”
How can I prepare? 5 simple steps
The virus may be new, but you really don’t need to buy anything new or special to be immunized from it. Epidemiologists say the most important aspect of preparedness does not cost us anything, which is calm.
“Don’t panic,” said Timothy Brower, professor of epidemiology and medicine at the University of California, Los Angeles. He added: “There is no point in panicking or inducing people to fear. Do not let fear and emotion drive your reaction to this virus. ”
There are some basic precautions you can follow, which are what you have learned to do exactly every day to avoid other respiratory illnesses. You previously read the instructions: wash your hands regularly. Cover your nose and mouth when sneezing. And when you get sick, stay home, don’t go to school or work, and drink plenty of fluids.
The Centers for Disease Control and Prevention recommends washing with soap and water for at least 20 seconds after using the bath, before eating, after sneezing, or cleaning the nose. It also advises against touching the eyes or nose, and cleaning the surfaces and objects that you usually use.
Do I need to wear a muzzle?
If you are not already sick, or are not working in healthcare then the short answer is no. And, of course, you don’t need to buy every box in the pharmacy near you to store it.
“The main goal of the muzzle is to prevent the person with the virus from spreading it to others,” says Brower.
The Centers for Disease Control and Prevention has written on its website consistent with this and said: “The Centers for Disease Control and Prevention does not recommend healthy people wearing a muzzle to protect themselves from respiratory diseases.”
Regular surgical masks prevent the spray from the sick person from spreading into the air, but they are not tight enough to prevent the spray already in the air from entering.
There are specialized respirators known as N95 respirators because they purify 95% of airborne particles, which are more efficient, and some online sellers have run out of quantities. But here’s the problem: It’s difficult to use this type of gag without training. They must be tuned and tested to work properly.
What do the reports of “treating” a patient mean?
In the context of infectious diseases, there are two types of “treatment,” says Bruce Ripner, professor at Emory University of the Faculty of Medicine.
He said that there is “clinical treatment”, which means that a person begins to improve and his symptoms such as fever and cough disappear.
And there is “treatment at the level of microscopic bodies”, and then the doctors decide that the virus is no longer present in the body, and therefore this patient cannot transmit the disease.
The first type is clearly visible in patients. But the second type says Ribner says: “We don’t have a good way about what it takes.”
There is still no antivirus to treat the new Corona virus.
But Todd Elleryn, head of the Department of Infectious Diseases at South Shore Health at the Massachusetts Institute of America, said that just as it does with colds, “most patients are treated for this disease alone” only with their own immune system fighting the invading virus. But for patients at risk, the incidence of the new coronavirus may be much more severe.
When will the Corona virus end?
Corona virus may follow a seasonal pattern, peaking in the winter months. It may affect many people now and then begin to recede in the northern hemisphere before returning in the fall. And perhaps his grip in the southern hemisphere.
“This virus may do whatever it wants,” McGuire said. He added: “The pattern that may spread is not fully known, but it is important to determine the burden that will fall on all of us, perhaps like the other corona viruses, a group of colds. It could be like regular seasonal flu. It could also be different and worse. ”
Scientists seem to have no definitive answer to the most pressing question in the world today: When does the Corona virus end?
Terms you should know
Corona Virus: This term refers to a family that is now made up of 7 known viruses that can infect humans, ranging from a common cold, to SARS or MERS, which are more deadly. The name comes from the shape of the virus under the microscope, which is a bubble surrounded by crown-like projections, which is known as the English Crown.
Covid-19: This term is sometimes used interchangeably with the Coruna virus, and the official name is SARS-CoV-2. The term Covid-19 refers to the disease caused by the virus. So SARS-CoV-2 causes covid-19 disease, just as HIV causes AIDS.
Zoological: The new Corona virus was transmitted from animals to humans, which made it zoonotic. SARS came from a civet cat, and the Mediterranean syndrome came from camels, but it is not yet known which animal the outbreak of the current Coruna virus came from. But the main suspect so far is the scaly anteater.
Community transmission: This is what happens when a disease spreads among a group of people in a specific area, none of them traveled to an affected site, and there are no close links between them and any confirmed cases. Until now, all American cases have contracted the disease from abroad, or from a husband or close contact with the virus. But US officials have said that there is at least one case in California that we can say is the first case known to be an example of a societal transition.
Asymptomatic transmission: Carriers of the virus without symptoms are the ones who do not show any sign of illness, but they carry the virus and pass it on to others. It is not clear to what extent the transmission is asymptomatic in the case of the new coronavirus.
Outbreak: a sudden increase in the number of cases with a specific disease in a specific place and time.
Epidemic: A major outbreak that spreads between a population or a region.
Pandemic: It is a pandemic in many countries and continents together. So far the World Health Organization has not announced that the current crisis is considered a pandemic, but many experts believe that the geographical spread of the virus has already reached this level or will arrive soon.
Isolation: Keeping the sick and injured away from those who are not. Hospitals have taken strict measures to isolate patients with the Coronavirus, using isolation wards, respirators that prevent spreading as well as several heavy protective equipment for health care workers.
Quarantine: Restrictions on the movement of people who appear to be healthy but may have been exposed to the virus. For example, the Americans who were evacuated from Wuhan and cruise ships remained in strict quarantine in military bases for 14 days, a period that scientists believe is the incubation period.
