VIENNA (Reuters) - The number of people receiving medicines for
the AIDS virus leapt by a quarter last year but more patients
need to be brought into treatment before they are too sick, the
World Health Organisation said on Monday.
Presenting the data at an international conference on AIDS in
Vienna, the WHO said an estimated 5.2 million people were being
treated for the AIDS virus at the end of 2009 after an extra 1.2
million people started treatment during the year.
It described the increase -- the largest in a single year -- an
"an extremely encouraging development" but called for more
programs to help patients receive treatment before the virus
starts to make them very sick.
"Starting treatment earlier gives us an opportunity to enable
people living with HIV to stay healthier and live longer," said
Gottfried Hirnschall, WHO director of HIV/AIDS.
An estimated 33.4 million people now live with HIV/AIDS around
the world. The United Nations says 15 million people need AIDS
drugs, so the latest increase means that only just over a third
are getting them.
Earlier HIV treatment can prevent so-called "opportunistic
infections" including tuberculosis (TB), which is the biggest
killer of people with HIV.
The costs for HIV treatment in 2010 will be about $9 billion,
according to the Joint United Nations Programme on HIV/AIDS
The WHO says deaths from TB could be reduced by as much as 90
percent if people with both HIV and TB started treatment earlier,
when their immune systems have not been weakened too much by the
The strength of a person's immune system is measured by CD4 cells
and this measure is used by doctors to assess when HIV-infected
patients should start receiving medicines.
The WHO previously recommended starting HIV treatment when a
person's CD4 count dropped below 200 cells/mm3 but it now advises
starting treatment earlier, at 350 cells/mm3 or below.
In rich nations, HIV patients begin treatment before their CD4
count drops significantly. As a result they are able to live
longer and more normal lives despite having the incurable virus.
A lack of funds and of healthcare infrastructure in poorer
nations, where the virus is more widespread, mean patients have
to wait until they are very ill before they get access to drugs.
WHO estimates that HIV-related deaths could be reduced by 20
percent between 2010 and 2015 if the new treatment guidelines
were broadly implemented. Evidence from scientific studies also
shows that earlier treatment can be an effective way of
preventing the virus from spreading.
"Because treatment reduces the level of virus in the body, it
means HIV-positive people are less likely to pass the virus on to
their partners," the WHO's Hirnschall said.
Bernhard Schwartlander, director for evidence, strategy and
results at UNAIDS, said investing in earlier HIV treatment could
save "millions of lives" and "millions of dollars" in future.
"People with weaker immune systems who come late for treatment
require more complex and costly drugs and services than those who
start treatment earlier," he said.
