Older, Men and Preexisting conditions are Vulnerable to Covid-19 – Virus 3

Graph 1. The older, the weaker.

The interesting facts that the most vulnerable groups to Coronavirus (Covid-19) are older, men and people with preexisting conditions.

In term of ages, the most vulnerable is 80 years old or more. Let’s say that from 100 death cases, almost 15 dead are 80 years old. However, all kids with age of 0 to 9 years old are survive.

The question then Why?

We might “guess” the answer is that immune system is weaker over age. The few facts:

- older has few white blood cells, and less capable to fight new pathogen such as mutant Covid-19.

- virus may damage white cells and immune system, then invites other pathogens. These conditions could cause illness, and death.

 Graph 2. Men more vulnerable than women

Men died more than women due to Covid-19 as shown on Graph 2. This fact not only to Covid-19, but also to SARS (China, 2003) and MERS (Saudi Arabia, 2012).

There are two possible answers why women are stronger than men to fight virus:

- women hormones support the stronger immune system

- environmental factors such as men are smoker than women; and men limit their practice to hygiene life such as not washing their hands frequently.

Graph 3. Chronic diseases contributed to dead of Covid-19 patients

The answer why people with preexisting conditions vulnerable to Covid-19 is quite similar to older condition in which their immune system is weaker.

Cardiovascular disease (CVD) patients are target for respiratory infection pathogen such as Covid-19.

Finally, in my opinion that it is important to stay healthy to fight any diseases!
