Impact of COVID-19

This survey has also found that due to COVID-19 the community level chest X-ray abnormality has been impacted in general and this would have impacted the prevalence of TB.

What needs to be done to address pulmonary tuberculosis (PTB)?

More needs to be done to address PTB in India like nutritional interventions for all those who are malnourished, occupation screening for TB, screening of old age people, as well as smoking interventions and cessation of alcohol. Also, the cost for treatment must be made affordable to all as 18 percent of the country’s population is burdened with high healthcare expenditure.
