25 Infectious Facts About the Coronavirus Pandemic (COVID-19) You Should Know

21Fatality Rates

The development of infection from coronavirus can lead to severe pneumonia, acute respiratory distress syndrome, sepsis, septic shock, and death. Patients who reported no pre-existing medical conditions had a case fatality rate of less than 1%. Therefore 99% of the patients who died after contracting coronavirus had pre-existing illnesses such as cardiovascular disease, diabetes, chronic respiratory disease, hypertension, cancer, etc.

22Median Age

In Italy, the median age of the infected by COVID-19 is 63 but most of those who died are older.

23Exponential Growth

On March 22, 2020, reported cases of COVID-19 passed 300,000. It took three months to reach the first 100,000 cases, only 12 days more to reach 200,000 cases and 4 more days to reach the 300,000 mark.

24Patient 31

South Korea confirmed its first case of COVID-19 in the country on January 20, 2020. In the four weeks following the incident, South Korea managed to avoid a major outbreak with only 30 people contracting the virus. This changed with the emergence of “Patient 31.” It’s not clear where Patient 31 became infected with the virus, but in the days before her diagnosis, she traveled to crowded spots and since then she has been linked to 80% of the Korean Covid-19 cases. As of March 22, 2020, South Korea reported nearly 9000 cases.

25Decreased Lung Function

Hong Kong doctors found that some recovered coronavirus patients may have reduced lung function and are left gasping for air while walking briskly. Some patients might have a drop of about 20 to 30 percent in lung function. Doctors still aren’t sure, whether their lung function will recover with time, or if it might be a permanent disability.
