LONDON — Young children and certain other people with the AIDS virus should be started on medicines as soon as they are diagnosed, the World Health Organization says in new guidelines that also recommend earlier treatment for adults.
The advice will have the most impact in Africa, where nearly 70 percent of people with HIV live. Many rich countries already advocate early treatment. WHO's new guidelines were released Sunday at the International AIDS Society meeting in Kuala Lumpur, Malaysia.
About 34 million people worldwide have HIV, the virus that causes AIDS. HIV attacks key infection-fighting cells of the immune system known as T-cells. When that count drops to 200, people are considered to have AIDS. In the past, WHO recommended countries start treating people with HIV when their T-cell count fell to 350; a normal count is between 500 and 1,600.
The new recommendations say to treat earlier, when the T-cell count hits 500.
In addition to children under 5. WHO says several other groups should also get AIDS drugs as soon as they're diagnosed with HIV: pregnant and breast-feeding women, people whose partners are uninfected and those who also have tuberculosis or hepatitis B.
The new guidelines mean an additional 9 million people in developing countries will now be eligible for treatment. At the moment, only about 60 percent of people who need the life-saving drugs are getting them.
"WHO has recognized that time is the most important commodity when it comes to battling the HIV epidemic," said Sharonann Lynch, HIV policy adviser at Doctors Without Borders, which contributed to the new guidelines.
She said that while the costs for rolling out this treatment might be expensive, the strategy would ultimately result in fewer HIV infections and deaths in the future.
"It's pay now or pay later," she said.
