Corona virus : What is the disease? What do you do to prevent yourself from getting it?

Corona virus  spread to more than 140 countries around the world.

What is the disease? What do you do to prevent yourself from getting it?

What are the symptoms?

Scientists confirm that Corona needs five days on average to show symptoms of the virus, which begins with fever, followed by a dry cough, and after about a week, the injured feel shortness of breath, which requires some treatment of patients in the hospital. Symptoms rarely appear as sneezing or runny nose.

The appearance of these symptoms does not necessarily mean that you have the disease, they are similar to those associated with the most common types of viruses, such as colds and flu.

Corona virus can, in cases of severe infection, pneumonia, acute pneumonia syndrome, impairment of the number of body parts and even death.

The elderly, and people with previous health conditions (such as asthma, diabetes and heart disease), are the most vulnerable group to HIV infection ..

The incubation period for the virus – between infection and the onset of symptoms – lasts about 14 days, according to the World Health Organization, but some researchers say this period may last up to 24 days ..

The researchers advise people who can transmit the infection – whether they have symptoms or not – isolate themselves for 14 days to avoid spreading the virus to others.

How did the virus start?

The virus is not “new” (used to infect animals), but it is new for humans after it can transmit between different types of organisms.

Many of the first infections are linked to a seafood market in Wuhan, in southern China.

Many people in China deal closely with livestock-carrying viruses, which are easily spread in the densely populated country ..

For example, severe acute respiratory syndrome (SARS) appeared first in bats, and then transferred to cats, and from there to humans.

The SARS epidemic began in China in 2002, with 774 people out of 8,098 infected.

The current virus is one of seven known variants of the Corona virus, and does not appear to be mutating yet. But while the virus appears stable, scientists continue to monitor it closely.

Corona Virus: What are the chances of dying from infection?

Researchers currently believe that between 5 and 40 cases out of every 1,000 cases of corona virus will end in death, and that the best estimate of the death rate is the death of nine people out of every 1,000 cases, or about 1 percent of them ..

But that depends on a combination of factors: your age group, your gender, the general condition of your health and the health system where you are.

How difficult is it to determine the death rate?

It is difficult for him to obtain a doctorate. Even counting cases is difficult.

Most cases of infection are not monitored for the majority of viruses, because people with mild symptoms do not tend to consult a doctor.

How can major cities prevent the spread of the Corona virus?

It is unlikely that the variation in death rates seen in different parts of the world is due to the presence of different copies of the virus ..

The reason why this is a variation of the ability of countries to discover more medium cases, which is more difficult in the monitoring and documentation, according to research conducted by the University of “Imperial College London”.

Thus, recording fewer cases than reality makes it easy to overestimate death rates. But you can also go wrong in the other direction.

This is because it takes time before the injury heals or dies.

Low pollution level in China after the outbreak of corona

If you include all patients for whom time has not been given to determine how their injury has progressed, then you reduce actual death rates, due to the absence of cases that will end in death later.

Scientists collect individual pieces of evidence for each of these questions, to build an image of the death rate.

Scientists, for example, estimate the proportion of cases with slight symptoms from small, specific groups of people who are closely monitored, such as people who return to their home countries from abroad.

However, a slight difference in the answers to these individual parts of the evidence will lead to major changes in the broader overall picture.

If you use the data only in China’s Hubei Province, where the death rate was much higher than anywhere in China, the broader rate would look much worse ..

Therefore, scientists give a rate between two ratios as the best way to estimate the number of deaths.

But even that does not include full proportions because there is no single death rate.

What is the Prospect Death For a person Like me?

Among some groups of people, the risk of dying from infection with the Corona virus is: the elderly, those with other diseases, and possibly men ..

In the first large analysis of more than 44,000 infections in China, the death rate was ten times higher among the oldest people compared to middle-aged.

The lowest death rates were among people under the age of 30, as there were 8 deaths out of 4,500 cases.

Deaths were at least five times more common among people with diabetes, high blood pressure, or those with heart or breathing problems ..

The number of deaths among men exceeded that of women.

All of these factors are intertwined with each other, and yet we do not have a complete picture of the potential death faces of every category of person everywhere ..

what is it Probability of death Where I live?

The possibilities for a group of 80-year-old men in China may differ greatly from what men of the same age group in Europe or Africa may encounter.

The future outcome of the patient’s condition also depends on the treatment he receives.

This in turn depends on what quality of treatment is available and the stage of the epidemic.

If the epidemic starts quickly, health-care systems can become crowded with people. There are not many ICUs or ventilators everywhere.

Do you It is more severe Dangerous from influenza?

We cannot compare death rates because many people with slight flu symptoms never choose to consult a doctor.

Therefore, we do not know the number of cases of influenza or any new virus every year.

However, the flu continues to kill people, as it does every winter.

As the data evolves, scientists will be able to draw a clearer picture of the groups most at risk if the Corona virus is widespread.

And according to the basic advice from the World Health Organization, you can protect yourself from all respiratory viruses by washing your hands, and avoid people who suffer from coughing and sneezing, while trying to refrain from touching your eyes, nose and mouth.

How do I protect myself from injury?

World health organizations say regular and thorough hand washing is crucial in controlling to avoid infection.

It is not yet known exactly how the Coruna virus spreads from person to person, but similar viruses spread through droplets, such as those produced when an infected person coughs or sneezes ..

WHO RECOMMENDS THEREFORE:

– Wash your hands thoroughly, registered soap viruses kill.

– Cover your mouth and nose when sneezing or coughing and wash your hands then to prevent the spread of the virus.

– Avoid touching your eyes, nose and mouth when touching hand to the surface of the likely presence of the virus on it, since the virus can be transmitted to the body in this way.

– Do not approach people with coughing, sneezing or fever, as it can spread small particles containing the virus in the air. It is preferable to be away from them for a distance of one meter.

How fast is the virus spreading?

Hundreds of new cases are reported daily around the world, and it is believed that health agencies are not likely to realize many cases ..

The virus had started to circulate in China, and soon spread to countries such as South Korea, Italy and Iran. Recently, cases of infection in many Arab countries were recorded.

With the spread of cold and flu in the winter, some hope that the epidemic will subside as the seasons shift.

School holidays can also limit the spread of the disease.

How dangerous is the virus and will my health improve?

According to the data of 56 thousand patients, WHO says that four out of every five people infected with Corona virus show only slight symptoms, and add:

80 Percent have mild symptoms.

14 Percent suffer from strong symptoms.

6 Percent seriously ill.

The death rate due to illness appears to be low (between one and two percent), but these rates are not confirmed.

Thousands are undergoing treatment yet, and some may die. So the death rate is likely to rise.

However, it is not known yet the number of minor cases that have not been reported, so it is also possible that the death rate will decrease.

And to consider the matter more thoroughly, about one billion people are infected with influenza every year, die of them between 290 and 650 thousand. The severity of the flu varies from year to year.

Can corona virus be cured and cured?

Treatment to date relies on basic measures, which is to keep the patient’s body able to perform vital body processes for the body, for example placing the patient on the breathing aid system until the immune system has completed its ability to fight the virus.

Work continues to develop an anti-virus vaccine, and researchers hope to start testing it in humans before the end of the year.

Hospitals are also testing the effectiveness of antivirals to see how they affect the treatment of this virus.

Corona Virus: What is the latest findings of scientists to treat people with it so far?

The human race is fighting a long-term battle against a virus five million times smaller than us. Within months of the new Corona virus appearing in the Chinese city of Wuhan, terror swept the entire world over the rapid spread of this virus ..

Scientists are making strenuous efforts to tackle the Corona virus and curb its spread around the world. Some have used sophisticated computer simulation models to follow and predict patterns of virus spread, while virologists are developing a new vaccine using genetic modification methods, while research is being done on drugs to treat people living with the virus ..

However, after decades of attempts to eradicate them, Corona viruses have proven to be a difficult enemy. The emerging corona virus belongs to the family of corona viruses or corona viruses, which causes a group of the most common and difficult to treat diseases, such as the common cold, for which we have not found an effective vaccine or a curative treatment so far, as well as acute and lethal respiratory syndrome (SARS). .

Corona virus infects humans and animals alike, and may spread from humans to animals and vice versa. The first case of corona virus, which causes respiratory syndrome in the Middle East, for example, was recorded in 2012, when a child was infected with a virus after contact with a camel carrier. And then recorded several cases of infection in humans after exposure to infected camels.

It is likely that the virus scientists Corona current, called the temporary “virus Corona emerging -2019”, appeared sometime in the beginning of December / December last.

Scientists at first thought that the virus passed to humans from bats, after finding two viruses in bats that carry many of the genetic characteristics of the human virus. While others saw that it came from snakes.

However, some scientists have recently pointed the finger of the endangered scaly ant, whose scales are used in traditional Chinese medicine, as a possible source of the virus. And some researchers suggest that the corona strain that now infects humans may have resulted from the mixing of two viruses, one of which infects bats and the other that affects the scaly anteater.

While the first cases of the emerging corona virus were recorded in humans who come into direct contact with infected animals, most of the recent cases with the emerging corona virus resulted from transmission between humans and some of them.

“We believe the virus was sourced from the local market, which has now been closed,” says Christelle Donnelly, a clinical epidemiologist at the Imperial College London and the University of Oxford. “.

Corona virus affects the upper respiratory tract and causes a range of diseases, including pneumonia. But there is evidence to prove that it may penetrate the body, affect the central nervous system and cause long-term neurological disorders.

It is worth noting that the word corona is the Latin equivalent of the word crown, and the virus derives its name from its annular shape covered by the crown-like protrusions ..

This includes cover the thorny DNA RNA “RNA”, which represents the genetic material. Unlike DNA, RNA allows the virus to mutate genetically quickly, and this helps it gain the ability to move from animal to humans or vice versa, or change its properties such as its ability to spread and the severity of symptoms it causes.

This is why it is difficult to fight the Corona virus, which appears from time to time in the form of new strains, because vaccines and medicines are unable to eliminate an ever-changing enemy ..

Donnelly and her colleagues estimated the ability of the new corona virus to spread by about 2.6, meaning that each patient transmitted the disease to another 2.6 people, noting that everything above the number on the disease prevalence index predicts the possibility of the disease becoming a rampant disease ..

The patient’s ability to transmit the disease may also vary, as some patients have an exceptional ability to spread the disease among large numbers of people. One patient, for example, transmitted the emerging virus to 14 health care workers. These patients contribute a large share to the spread of the disease.

This is because these patients spread more viruses through coughing and sneezing, compared to other patients. These patients have played a major role in the spread of infection “SARS” and “MIRS”, and blocked the efforts they include.

However, the ability of patients to spread the virus in this manner depends on many factors, including the biological characteristics, type of virus and the environment in which they live. Thanks to their strong immune systems, some people may carry the virus for a while without showing them only a few or moderate symptoms, and this allows them to travel and travel long distances even though they have the disease ..

In contrast, some people experience severe symptoms once they are infected with the virus. They sneeze, cough, and spread the disease among more people ..

General preventive measures, such as wearing face masks, washing hands and quarantining patients, may reduce the spread of the disease.

Early diagnosis of viral cases primarily helps to contain the outbreak. In this regard, the American Center for Disease Control and Prevention has created a toolkit based on DNA analysis, to detect the emerging corona virus. These tools rely on a new technology that results within four hours, although it requires expensive laboratory equipment.

Researchers at the University of California and a number of biotechnology companies are developing modern diagnostic methods that rely on CRISPR technology for genetic modification to monitor the virus in an infected person before symptoms appear ..

As for treatment, the main treatment for these viruses so far is “antivirals”, which weaken the ability of viruses to enter cells and prevent them from multiplying and multiplying inside the cell or moving from infected cells to others.

Currently, some scientists are researching “Remdisfer”, a broad-based antiviral, that is, it is effective in preventing multiple viruses from multiplying. This drug was developed specifically to combat the spread of the Ebola virus. And when the researchers gave the drug “Remdisfer” the first case of the “emerging corona virus 2019” in the United States, it recovered within days ..

Other research supported the effectiveness of this drug in the treatment of Corona virus that causes the syndrome “MIRS” in mice.

Laboratory tests have shown that the drug “Remdisfer” was effective in preventing the emerging virus from infecting human cells, but the drug has not yet been approved by regulatory authorities for use in patients with the emerging corona virus ..

The same study indicated that “chloroquine”, the drug used to treat and prevent malaria, was also effective in treating the emerging corona virus ..

Doctors at a Wuhan hospital in China are conducting clinical trials of two drugs used to treat HIV. But now the fear that corona viruses, given the high speed they mutate, will develop immunity against antivirals.

At the same time, researchers are conducting studies on the use of quantum dots, which are semiconductors only a few kilometers in size, to estimate their effectiveness in preventing human corona viruses from infecting cells ..

Parallel to these studies, time scientists are racing to develop a vaccine against the emerging corona virus to curb its spread.

Vaccines help the immune system to recognize some features of the virus, such as the protein composition on its outer shell, and the development of antibodies to fight the virus if infected. But these constantly changing viruses easily escape our immune systems. That is why he has not yet developed a vaccine against the common cold.

The coalition announced innovations pandemic preparedness for a grant of nine million dollars to the company “Anovio” for drugs to develop a vaccine for the virus Corona within 16 weeks.

Researchers at the company are developing the vaccine by producing large amounts of nucleic acid sequences to predict mutations that may occur in the virus and help it to produce a new strain ..

But another way to develop the vaccine is to extract some cells from a patient who has recovered from the disease and examine them to extract antibodies from them, and then copy the antibodies to study their effectiveness as a vaccine for the virus.

The search for a new vaccine treatment or vaccine is still ongoing, and research may take months or years. But up to this point, we can only monitor the virus and try to check its spread  , months or years
