In the period of October-November 2021 ,there is high level of air pollution in Delhi and NCR.
Air pollutants contain particulate matters of different sizes.
Pollutants containing sizes PM2.5 and PM10 are very dangerous.
These pollutants of size pm2.5 and pm10 can enter the respiratory tract of children.
PM 2.5 can easily enter the alveoli and damages it.
High pm2.5 was defined as pm2.5 level more than 10.75 mcg/cubic meter.
In one study published online on 29.10.2021 in Experimental biology and Medicine,out 810 children,220 were included in study and they were divided into two groups,one with high risk group for community acquired pneumonia(126 children) and second group with low risk for community acquired pneumonia(94).Pneumonia was defined by radiographic evidence of opacity consistent with pneumonia.
It was observrd that more cases of pneumonia were diagnosed from the area with high pm2.5 as compared to low pm2.5
The mean level of pm2.5 was 10.75mcg per cubic meter during study period which is lower than the high level set by U.S.Environmental protection agency .
According to the reports by SAFAR(System of air quality forecast and resaearch) Delhi,NCR,the highest level of pollutants including pm2.5,pm10,ovc,so2,co,nitric oxide are being seen in Delhi NCR air between midnight and 10 am in the morning as on 19.11.2021.Air quality index is in very poor category in Delhi,NCR as on 19.11.2021
So, air pollution is a risk factor for pneumonia in children
