Not only the elders of the sick: These people are the most endangered by the coronary.

Lee Wenliang, a doctor in China who raised awareness of the new coronary, died of the virus in February at the age of 34. His death was shocking not only because of his role in raising people's awareness of the epdemia that was taking place but also considering that young people had no high risk of dying because of his youth.

Is it possible that Dr. Lee died because of how much time the doctor spent with serious coronary patients, how long was he infected with a very high dose? The turnover, although he was one of the first young health workers to die from exposure, was unfortunately not the last.

The importance of viral dosage is being considered very carefully in the discussions on the Coronobrus. Like any other poison, viruses are more dangerous when they enter into the body in larger amounts. Small initial exhibits tend to lead to infections with mild or no symptoms at all, while high doses of the virus can be fatal.

From the policy perspective, we need to consider that even non-exposure to the body can be the same. Entering a building where there had once been a man of coronaryism is not dangerous enough to be around an infected person for a long time.

This may seem obvious, but many people are not making that distinction. We need to focus more on preventing high dose infections.

Even large amounts of the virus can be replicated within our cells and cause serious diseases in vulnerable individuals with weak immunity. In people in good health, however, the immune system quickly reacts as soon as you notice that a virus is growing inside. The recovery depends on who wins the race: distribution of the virus or immunity activity.

Virus experts know that viral doses affect the severity of the disease. In the labs, rats who receive small doses of the virus remove and recover, while the same virus in high doses kills them. The dose's sensibilities have been obsessed with any traditional viral infection that has been studied in animal labs, including coronarys.

People also show sensitivity to viral doses. Volunteers have allowed themselves to be exposed to low or high doses of light viruses that cause fever and diarrhea. Low doses have rarely developed visible signs of infection, while high doses have usually led to infections and more severe symptoms.

It would be unrealistic for experiments to manipulate viral barrels in humans for pathogens as serious as coronarys, but there is evidence that the dosage also matters to human coronary. During the 2003 SARS choreography explosion in Hong Kong, for example, a patient infected many others living in the same residential complex, resulting in 19 deaths. The spread of the infection is thought to have been caused by viral particles spread across the residential complex from the original patient's residence. As a result of high viral exposure, neighbors living in the same building were not infected more but also more likely to die. Otherwise, distant neighbors, even after being infected, had suffered less.

Small dose infections can even strengthen immunity by protecting it against high dose exposure in the future. Prior to the discovery of vaccines, doctors often deliberately infected healthy individuals with oak juices. Low dose infections were unpleasant but survived, thus preventing major incidents of the disease when these individuals were later exposed to smallpox in uncontrollable size.

Despite evidence of the importance of viral doses, many of the epidemological patterns used to inform politics during this pandemic have been ignored. This is wrong.

People need to take extra caution against high dose exposure, which is more likely to occur in close personal interactions such as at meetings in cafes, in bars with many people, and during a time in a room with Grandma é and from touching our face after taking a high dose of the virus into our hands. Personal interactions are more dangerous in closed spaces and small distances, with the dosage passing on time. The interactions of the case that do not violate the two - inch distance rule between you and the other person, such as paying the cashier at a mall, are another story.

But the dosage matters, medical personnel face extreme risks, as they face the most ill, patients with huge amounts of the virus. We need to prioritize the safeguards for them.

For everyone else, the importance of social distance, wearing a mask, and good hygiene is good because these practices reduce the spread of the infection but also tend to lower the dosage and thus the mortality of infection. While preventing viral distribution is a social advantage, avoiding high dose infections is a personal experience, even for young people.

At the same time, we need to avoid irrational and increased response to exposure to lower doses of the virus. The clothing and package of foods that are ecstatic to someone with the virus seem to pose a low risk. Healthy people who are together in a shopping center or a workplace experience a small risk as long as they keep social distance measures.

The total quarantine of society is the most effective step to prevent the virus, but it is expensive both economically and psychologically. When society eventually re-opens, risk reduction measures such as keeping its personal space and practicing the right washing of hands will be essential to reducing high dose infections. High risk sites for high dose exposures, such as stadiums and large collections, must remain closed. Essential and dangerous services such as public transportation should be allowed to operate, but people have to follow security measures such as wearing masks, keeping social space and never going out while they have a fever.

Now is the time to stay home. But hopefully this time will be short. When we begin to leave the house again, let us wisely do so, knowing the importance of viral doses.
