WHO defines treatment adherence as ‘the degree to which a person's behaviour of taking medication corresponds with the health care provider's prescription. Poor adherence has been reported in areas where food has been scarce, and where clients have to travel long distances to seek medical care and is one of the major causes of HIV treatment failure. HIV treatment failure has three definitions, namely: clinical, immunological and virological. According to the Zimbabwean ART Guidelines, clinical failure in adults is defined as a new or recurrent clinical event indicating severe immunodeficiency (WHO clinical stage 3 and 4 conditions) after 6 months of effective treatment. HIV treatment failure is also defined as a CD4 count which falls below the pre-therapy baseline or there is a 50% fall from the treatment peak value (if known) or CD4 count levels are persistently (at least 2 results) below 100cells/mm3. Virological failure is defined as plasma viral load above 1000 copies/ml based on two consecutive viral load measurements after 3 months, with adherence support. The United Nations declared to end the HIV pandemic by the year 2030 by ensuring that 90 % of all people living with HIV are aware of their status, 90 % know their status being on antiretroviral therapy and 90% of people living with HIV on antiretroviral therapy achieving viral suppression. In a study done in Gabon, the rate of virologic failure on first-line ARV was 41.3% (36.4-46.4). As a proxy for first-line ART failure, the National HIV Drug Resistance Monitoring survey at 12 sentnel sites in Zimbabwe, from the period of 2009 to 2011 found that the proportion of clients with HIVDR at 12 months, after being initiated on ART was 3.3%. A case-control study done in Kenya established that baseline CD4 count < 50/ml (H.R = 7.07, (95% CI = 4.92 - 10.15) was significantly associated with ART failure. According to , the most common side effect of antiretroviral therapy among HIV-positive clients was peripheral neuropathy. Dizziness, skin rash, and vomiting were more frequently reported signs and symptoms among the non-adhering clients.
