Due to the following reasons:

- Chronic medical diseases e.g. diabetes mellitus , hypertension and cardiovascular diseases in general more common in males and as you know mortality of COVID-19 increase in patients with chronic diseases.

- Estrogen level is high in females which protect them from cardiovascular diseases.

- Testosterone level is high in males which lead to more risky behaviors e.g. smoking , drinking, and reluctance to see medical help earlier and all these behaviors lead to more mortality in COVID-19 patients.

Dear all, the mobility (or Dynamic) factor is the most important in catching the desease. I think weman are less active in their daily life compared to men. In addition of there great care taking of themselves. My Regards

Females probably due to their lesser movement as compared to male result in lesser risk of COVID-19

Lower mortality of females compared with males in COVID-19 pandemic

It is related to less outdoor exposure to SARS-CoV-2, protective effect of estrogens and progesterone, less smoking rates, and being a stronger sex.
