People with pre-existing health conditions and a history of chronic illness are at higher risk for viral infections.
Acute respiratory infection caused by new strain SARS-CoV-2 is an acute infectious disease. Patients with symptoms of fever, cough, shortness of breath, severe pneumonia, can cause acute respiratory failure and the risk of death, especially in people with chronic medical conditions, background disease. Up to now, there is no specific treatment and preventive vaccine.
A preliminary study from the Carlos III Health Institute in Spain – a country with more than 94,000 cases and about 8,300 deaths due to Covid-19 – shows that the infection rate in men is slightly higher, accounting for 52 %, while women account for 48%. According to this study, the number of male deaths is almost double that of female deaths.
Therefore, to prevent the risk of SARS-CoV-2 infection and to avoid affecting the lives, people who have the following conditions need to increase resistance and limit contact with SARS -CoV-2.
Who is most vulnerable to SARS-CoV-2?
People 65 years and older
The risk of death increases with age, 31-59% of people aged 65-84 will be hospitalized with SARS-CoV-2 and 4-11% will need special care.
Elderly people are more susceptible and more likely to die from SARS-CoV-2 due to age-related decline in immune function, complications, and impaired lung function. According to an out-of-age health expert, other factors that make a patient vulnerable or die are nutrition, sleep and exercise problems.
Obesity has also emerged as a cause of concern in recent times. The American Heart University has listed obesity as a high-risk factor for people with SARS-CoV-2. According to the CDC assessment, 42.2% of the population, or about 140 million Americans, are obese.
The immune system of obese people does not have the ability to fight infections as well as those of moderate weight. Therefore, obesity causes many health disorders, increasing the risk and severity of SARS-CoV-2 such as hypertension and heart disease …
Hormones can also be an influencing factor. According to a 2017 study by the University of Iowa (USA), among rats infected with the SARS virus, males die more, and female rats with ovaries are also more likely to die, suggesting that estrogen may have a role in coping with virus.
Persons with immunodeficiency
If you are immunocompromised, you are being treated for cancer, you are at higher risk for getting SARS-CoV-2 virus. Because people with weakened immune systems have a weak immune system, making them unable to fight off infections, increasing the risk of infection.
