Treatment of TB

Anyone having any of the above symptoms should visit the hospital immediately & see a doctor. Samples would be taken to rule out pneumonia & confirm tuberculosis.
Your doctor would place you a number of drugs, about 4 (Rifampicin, Isoniazid, Pyrazinamide & Ethambutol or Streptomycin), with dosages & how long you would take it.

Treatment for TB usually can last anytime from 6 months to 2 years depending on the extent of the disease & damage done by the disease.
You should continue to take your drugs as directed by your doctor, mostly under supervision of the doctor.

How is Tuberculosis Transmitted

Its is a very contagious disease that is transmitted through air droplets. That is, if someone who has tuberculosis coughs near you, you can also carry it.

Prevention of Tuberculosis

Vaccination: this usually provided at birth. It is usually the first vaccine given to a child immediately after birth, as soon as possible, according to the NPI schedule. We encourage mother’s to ensure their children are properly vaccinated in order to prevent all these diseases. Remember that Vaccination is free at any government health facility.
