Feasibility and Effectiveness of Community Based Isoniazid Preventive Therapy in Kenya

"In the intervention group, the household contacts of enrolled TB/HIV co-infected patient are visited at home by community health workers. Those contacts providing informed consent and considered fit (assessed by simple questionnaire) are assumed not to have active TB and are eligible for IPT. They are offered isoniazid at 300mg (5 mg per Kg for children) once daily for 6 months, regardless of their HIV-status.~In the control group, in line with routine care, eligible index cases are requested to send their contacts to the clinic for evaluation. Contacts presenting to the clinic will be screened for TB and receive IPT, if under 5 years and when active TB is ruled out as per the current national guidelines.~All contacts (both intervention and control group) are followed up monthly to assess occurrence of symptoms suggestive of TB."
