My 3 years old has TB, will it affect his growth?

My child is 3 years old and has TB. The doctor says that it is in its initial stage. He gave medicines for 6 months. The test he took says: 20 MM MT Positive. How did he get this because nobody around us has this disease? I sit curable and will it affect his growth?

 

Primary complex is the name of the illness of TB seen in children. The infection occurs in the majority of children in endemic countries, like India. It is not a cause for worry, as it is treatable and does not affect growth.
