There is no scientific consensus on the cause of death from coronavirus infection in the United States, but it seems all the more confusing when you consider that a new scientific study suggests that more than 90% of people infected with coronavirus never develop symptoms.
This happy group is left with dry cough, fever and Body pain now associated with COVID 19, even if the virus spreads in their body and potentially spreads to others. Since the outbreak of the Covid-19 virus, the most puzzling and disturbing aspect of this pandemic has been the number of people infected with the virus. Traditionally, it seems that some populations are more affected than others, but not in this case.
It seems that the more serious forms of this disease occur in the form of respiratory infections such as pneumonia, diarrhoea, diarrhoea, vomiting and even death.
This new understanding of the role of silent spreaders is why it is now being proposed that people wear masks when they leave the house. This recommendation is primarily aimed at preventing asymptomatic people from inadvertently spreading a disease that they may not even know they have. These trends give us a new opportunity to strategically mitigate the consequences of this pandemic.
Why does COVID 19 kill some patients and leave others with mild symptoms, and why does the same virus affect people in different ways, killing some while fortunately others do not know they have been infected in the first place?
AIDS is caused by a virus called HIV and infects and kills millions of people around the world. It is the virus that apparently causes the body to attack both healthy cells and viruses - weakened cells. Some infectious disease specialists studying this phenomenon believe that COVID 19 can cause serious health problems in adults, including young and otherwise healthy people, but not children.
It's a really interesting and open scientific question, "said Christophe Fraser, who studies the spread of Ebola and HIV. To solve the mystery of the core of the Covid-19 pandemic, scientists have turned to a different type of virus. In the mid-1990s, researchers found a variation of a gene called CCR5 that makes some people resistant to the virus, but others not.
SARS and CoV-2 seem to be transmitted mainly by droplets, but humans release much more of the virus in the form of aerosols such as sweat, saliva and other bodily fluids. SARS spreads through a finer aerosol that hovers long in the air, allowing one person to infect many.
Initially, experts thought children could tolerate the new coronavirus because they have healthy lungs that are less exposed to cigarette smoke and pollutants than adults, which is especially the case in China, where air quality is a known problem. But a 2019 study of healthy people showed that some inhaled far more particles than others when talking to their parents, grandparents and other family members.
But that does not mean that children cannot pass the virus to other, more vulnerable members of the community. With the new coronavirus, "the virus seems to be transmitted well, but it still seems that young children (10 to 15 years old) don't get too many symptoms, which is a good sign that they just don't get the disease," Creech said.
Finding out why children are so unaffected could lead to breakthroughs in understanding how and why the virus sickens and kills other age groups, he said. This means that the new coronavirus behaves differently from other viruses, such as seasonal flu, which is generally more aggressive and dangerous for older people than for younger ones. The immune system of older people is not yet developed, and their immune systems are getting weaker, "he said, according to the Centers for Disease Control and Prevention.
The severity of the infection depends on whether the patient was previously exposed, and Esper and others are investigating the issue. One of the first doctors to treat the first emerging cases of this new virus was Dr. John D. Dolan, a professor of infectious diseases at the University of California, San Francisco, who contracted the serious infection and died of it. The majority of previously healthy people afflicted by acute Covid-19 infection were health workers.
One of the clues to why otherwise healthy people develop such severe forms of the disease is that the trend seems to counteract what we think we know about this type of viral respiratory infection. To understand this, recall diagrams like the one that was leaked to the media in the context of efforts to slow the spread of Covid-19.
SARS - CoV-2 also appears to have the ability to infect white blood cells, the main subgroup that uses the virus as a tactic. By zooming in on the cells targeted by the new coronavirus, scientists can gain a better understanding of why the disease can infect adults more, Rubin says. If this is the case, ADE could help explain why it is able to cause the adult immune system to flare up more dramatically during an infection.
