The age distribution of COVID-19 cases seems more asymmetric than that of 
lab-negative pneumonia cases. The association of the CVID-19 with older 
ages, as well as the lower frequency of the disease in children, are consistent 
with reports of other countries. The underlying cause of these observations 
needs to be investigated. It should be noted that part of the cases currently 
diagnosed as non-COVID-19 pneumonia, might be false negative COVID-19 
cases. This is especially the case in children and teenagers, as proper 
pharyngeal sampling in these age groups is not a trivial task. High frequency 
of hospitalization due to pneumonia is expected in children during the winter 
because of the anatomy of their respiratory tract.      

 

 

 
* Comorbidities means the presence of at least one underlying 
disease, including: cardiovascular, liver, kidney, blood, 
neurological diseases, diabetes, Asthma, immunodeficiency, 
and other chronic diseases. The results show that the 
prevalence of comorbidities is higher in more severe 
outcomes.
