Pre-Exposure Prophylaxis or PrEP

Pre-exposure prophylaxis (PrEP) involves putting HIV negative people on antiretroviral drugs (ARV) with the aim of protecting them from HIV infection. This blog looks at some of the pros and cons of PrEP.

Do High HIV Prevalence Countries Have the Resources for Test and Treat?

When the 'treatment is (or as) prevention' (or 'test and treat' and various other names) hypothesis was first mooted, some wondered how it would work. The plan is to test everyone in a population for HIV regularly and treat everyone found to be infected immediately, rather than waiting for them to reach a particular clinical stage. Adherents of the strategy have vaguely suggested testing 80% or so of a population but this has not been achieved in any high prevalenc country. But if such levels of testing are achieved, how often would testing need to be carried out, and what would be the feasibility of testing such large numbers of people that often?

These issues are still fuzzy. But recent research suggests that many people are unaware of their HIV positive status, even where high rates of testing have been achieved. According to Salim Abdool Karim, this illustrates "the need for frequent repeat testing and comprehensive prevention efforts".

Whatever 'frequent' testing means in high resource, low HIV prevalence countries, it seems an unlikely option in high prevalence countries, which are all poor. Health services are generally not able to cope with relative simple health conditions and in many countries are simply too expensive to afford or too distant to reach. Karim's study shows that rates of new transmissions, which are unbelieveably high in parts of South Africa, are also high among those who tested negative only a short time before.

Getting everyone to test once for HIV, even where 'everyone' means 80%, is hard enough, but getting them to test every year would be a whole lot harder. And every year is not enough in the South African study area in question. So test and treat still raises more questions than answers; are there any high prevalence countries that can meet the challenge of testing so many people so frequently?

I am from UK, I was diagnosed of ALS disease (Lou Gehrig’s disease) in 2010 and I have tried all I could to get cured but all to no avail, my

life was gradually coming to an end, until i saw a post in a health forum about a herbal doctor from Africa who prepares herbal cure to cure

HIV and all kind of diseases including HIV, ALS, MND, Epilepsy, Leukemia, Asthma, Cancer, Gonorrhea, genital warts etc, at first i doubted if

it was real but i decided to give it a try, when i contacted this herbal doctor via his email, he prepared an ALS herbal portion and sent it

to me via courier service, when i received this herbal portion, he gave me step by step instructions on how to apply it, when i applied it as

instructed, i was cured of this deadly disease within 7 days, I could not walk or talk understandably before but after i took the herbal cure

as he instructed i regained strength in my bones and i could talk properly unlike before, I am now free from the deadly disease, all thanks
