Initial data from Italy and New York indicated that asthma does not significantly increase the mortality risk. However, bigger studies do show a slight increased risk. They did not break down asthma into severity but at this time I assume, after looking at the numbers, that it is uncontrolled asth...

Why do we get allergies throughout life and what can we do about them? If you already have allergies you may want to try food and/or environmental oral desensitizations, allergy shots or allergy drops.
