START ART EARLIER !!

With better drugs…

Viral load accessible

Infant diagnosis

Long term retention

Community involvement

Social support systems

               Zambia, Fredrick Sinyinza

Dear Lut,“With the implementation of the new guidelines rolling out of ART is not without challenges. At one of the main sites, where I work, the number of pt starting HAART since we started using the new guidelines ( late sept this yr)  has increased by 37% (considering pts with  WHO stage 1,2 and CD4 200-350)), as a result the clinic has become congested, the patients are complaining and the lab is complaining (too many specimens).”

START ART EARLIER !!

The number of people estimated to be in need ofantiretroviral therapy at the end of 2009 increased from 10.1

million to 14.6 million [13.5 million–15.8 million] WHO report 2010
