9% of pediatric tuberculosis patients found resistant to drug, says a new survey

Also, the resistance was highest among the children between 5-9 yrs of age, then between 10-14 yrs old, and least amongst children less than 5 years old.

As quoted by the Times of India, "The result of the survey came as a surprise," said Dr Amar Shah, National consultant for HIV/TB for RNTCP. Estimates so far have showed that the prevalence of multi-drug resistance (MDR) in new TB cases, of which children comprise a large portion, is between 2% to 3%.

"Our survey showed a staggering 9%, which is quite high. It's surprising because many of them haven't been exposed to antibiotics before, which means they are acquiring the infection in the MDR form at the time of transmission," he said.

Diagnosis of TB in children is complicated as the bacteria, Mycobacterium tuberculosis,can mimic many other common childhood diseases, including pneumonia, general bacterial and viral infections and respiratory infections. "Children also find it hard to cough up the sputum for the samples. They tend to swallow instead," said Dr K Sachdeva, Additional Deputy Director General, Central TB division. "So accuracy in the traditional tests is often ambiguous," he said.
