Defaulting on ARVs ups risk of transmission
Survey finds many patients confused about treatment
ON THE eve of South Africa’s national Aids conference taking place in Durban this week, Health-e News has found that people are defaulting on their antiretrovirals and posing a risk to others.
Healthcare workers are finding that HIV patients on treatment sometimes stop taking their medication in the mistaken belief that they have been healed – despite knowing that the disease is incurable.
The issue relates to the “undetectable viral load” diagnosis patients receive when their antiretroviral therapy starts working and causes the amount of virus in their blood to drop to a very low level.
The confusion arises because of a misunderstanding of what an “undetectable viral load” actually means. People who hear this result when they go for testing are quick to jump to the wrong conclusion that the virus is no longer in their blood, that they are therefore no longer sick and now have no need for treatment – and they default.
A recent snap survey carried out by Health-e News in a rural community in Mpumalanga found that when asked what the words “undetectable virus load” meant, all the respondents said it meant they no longer have HIV.
Sam Vilakazi, a patient from Mbombela, had blood taken for his CD4 count to be measured. When the results came back with an undetectable viral load, he assumed he was no longer infected and stopped taking his antiretroviral treatment (ART).
“At first, things were fine. And then I started drinking again, smoking and having sex without a condom. Even though my partner told me that it was impossible for me to be HIV-negative and I should have asked more questions, I ignored her because I thought she was jealous that my virus is gone,” Vilakazi said.
“After months of not taking treatment, and with my bad behaviour, things went from good to bad. I became seriously ill. When I returned to the clinic, I was told that I should not have stopped taking my treatment. I was ill because I defaulted,” said Vilakazi.
Nursing sister Dumisile Shabangu said when a patient has an undetectable viral load it doesn’t mean the HI virus is no longer inside their body. It just means that their medication is working and that the amount of virus particles in their blood has dropped so low that they cannot be counted, and they are said to have an “undetectable viral load”.
“For most tests used clinically today, this means fewer than 50 particles of HIV per millilitre of blood. Reaching an undetectable viral load is a key goal of ART. An undetectable viral load means a person is about 96% less likely to transmit the disease,” Shabangu said.
Gugu Ngema also made the hasty decision to stop taking her ARTs. “English is not my mother tongue and sometimes the explanations we get from nurses are not clear. I remember when I was told about my ‘undetectable viral load’, I asked the right questions to find out what this meant. A nurse said to me ‘the virus is not detected in your body and you will not infect another person with the HI virus’. And so I stopped taking my treatment and defaulted. Then I got sick and lost so much weight and I was embarrassed to go to the clinic, I began using traditional medicine until my family advised to go back to the clinic before things got any worse,” Ngema said.
Lay counsellor Zodwa Mbokani said many people stopped taking their treatment when they were told they had an undetectable viral load.
“My advice to people living with HIV and who are on treatment is to always ask questions and never, ever decide to stop taking medication without your nurse and lay counsellor knowing. The most important thing you must know is that once you start ART, there is no turning back,” Mbokani said.
Explained nurse Thandeka Bhengu: “Even though we are fully aware that there is no cure for HIV, we feel a decision to stop treatment is rational because we have been praying to live life without the HI virus. So when we hear the words ‘undetectable viral load’ we feel a rush of emotions and forget to ask the important questions about what it means.”
Healthcare workers believe this situation is all too common because of a lack of information about HIV as well as how the treatment works, claiming that defaulting on ARVs is the biggest challenge for people living with the virus.
