One of the most curious aspects ofCOVID-19 [FeminineWhen infected, some people remain completely asymptomatic, while others are hospitalized and unable to breathe. Since the beginning of the pandemic, health experts and researchers have studied highly infectious virus in the hope of understanding why the type of infection varies so dramatically to a person base. According to an infectious expert of the disease, it boils down to three factors. Read to read for the three most common factors that influence the type and severity of the symptoms of COVID - and to guarantee your health and health of others, do not miss these Without signs that you have already had coronavirus.

The first and only controllable part of the equation is the way the person is infected and the dose of the received virus, saysCarlos R. Oliveira, MD, Ph.D., Yale Medicine Medicine Medicine Pediatric Infectious Disease Doctor. "For example, if an infected person with COVID-19 directly affects you, you will probably get a much higher dose of the virus than if you are infected by touching a contaminated area," he says. "A higher infectious dose generally leads to faster and more severe symptoms."

This is an excellent example of why wearing a mask and social distancing is so crucial in protecting yourself and others. Several studies have concluded that masks are effective in preventing tiny infected viral particles from transmitting people to anyone. Although they may not cease all, they will certainly help reduce viral load, probably leading to less serious infection.

Another crucial factor in the determination of the type and severity of the symptoms of COVID is "the state of health at the time of infection", according to Dr. Oliveira. At the beginning of the pandemic, it became clear that people with certain pre-existing conditions were more subject to severe infection than others.

According toCDCSomeone who suffers from cancer, chronic renal disease, COPD (chronic obstructive pulmonary disease), down syndrome, heart conditions, such as heart failure, coronary artery disease or cardiomyopathies, an immunodefromised state (weakened immune system) of the solid member graft, obesity (body mass index [BMI] of 30 kg / m2 or longer but <40 kg / m2), severe obesity (BMI ≥ 40 KG / M2), sickle sickness, type 2 diabetes mellitus, is pregnant or smoker, are at the highest risk of severe infection.

"It is particularly important for people to increase the risk of COVID-19 serious illness and those who live with them, to protect themselves from obtaining COVID-19," the CDC warns.

Age is also a very important factor, according to Dr. Oliveira, influencing not only the severity of the virus, but also the symptoms he can manifest. "Several studies (including Agyeman, Mayo Clinic, 2020) have shown that in adults, smell loss is an early manifestation, occurring up to 40 to 60% of infections. It may be Also the only manifestation of infection in some adults, "he emphasizes.

On the other hand, the loss of smell is rarely seen in children, he adds, citing the study of symptoms of Covid. "In fact, gastrointestinal symptoms, such as abdominal pain, loss of appetite and diarrhea are frequently initial manifestations in children, occurring in about 1 of 3 cases".

"As is the case for many infectious diseases, the progression of discernible symptoms can be quite variable," says Oliveira.
