South Africa has invited experts of the World health Organization (WHO) to brainstorm on a virulent strain of tuberculosis that has claimed 70 lives, local media inform Friday.

Such encounter, scheduled Tuesday and Wednesday on Johannesburg, aims at finding a formula to fight multi-drug resistant (MDR) and the extremely-drug resistant (XDR) tuberculosis.

The African nation expects the gathering helps to review current plans and project others to reduce effects of that scourge.

South Africa registers 330,000 tuberculosis cases, from them 6,000 with the MDR variety.

The disease has been discovered in several provinces in the country, including KwaZulu-Natal, Gauteng, Free State, with the Northern Cape and North West the latest to confirm its existence over the past few days.
