New danger in Africa: HIV-TB combined epidemic

Washington, Nov 2 - A deadly combination of HIV and tuberculosis (TB) is rapidly spreading in sub-Saharan Africa and has gone largely unnoticed so far.


Health systems, moreover, are not adequately equipped to diagnose, treat or contain the co-epidemic due to unanswered scientific and medical questions, according to a report issued Thursday by The Forum for Collaborative HIV Research here.


The report notes that approximately one-third of the world's 40 million people with HIV/AIDS are also infected with TB and the mortality rate due to the co-epidemic is five-fold higher than that for tuberculosis alone.


'The eye of the storm is in sub-Saharan Africa, where half of all new TB cases are HIV co-infected, and where drug-resistant TB is silently spreading,' said Veronica Miller, one of the authors of the report.


'Unlike bird flu, the global threat of HIV-TB is not hypothetical. It is here now. But the science and coordination needed to stop it are utterly insufficient,' she said.


The HIV-TB co-infection was first detected 23 years ago. Without proper treatment, 90 percent of people living with HIV die within months of contracting TB.

Something change, if this "chimera" rapidly spreading now, after 23 years.
What stopping it to not spread wider? The rural transportation ambient, and only a impossibility of the victims to have enaugh health to take an airplain?

Deadly HIV-TB co-epidemic sweeps sub-Saharan Africa: report

7 hours ago

PARIS (AFP) — Drug-resistant tuberculosis and HIV have merged into a double-barreled epidemic that is sweeping across sub-Saharan Africa and threatening global efforts to eradicate both diseases, according to a report released Friday.

Over-burdened health systems are unable to cope with the epidemic and risk collapse, said the report, which calls for urgent measures to curb its spread.

A third of the world's 40 million HIV/AIDS sufferers also have TB, and the death rate for people infected with both is five times higher than that for tuberculosis alone.

The situation is aggravated by surging rates of multi-drug resistant (MDR) and extensively drug-resistant (XDR) TB precisely in those areas where the rates of HIV infection are highest.

MDR and XDR tuberculosis are resistant to some or all of the standard drugs used to fight the disease.

"Now the eye of the storm is in sub-Saharan Africa, where half of new TB cases are HIV co-infected," said Veronica Miller, co-author of the report and director of The Forum for Collaborative HIV Research, which issued the study.

"Unlike bird flu, the global threat of HIV/TB is not hypothetical -- it is here now," she said.

One third of the world's population carries the tuberculosis bacterium, but the disease remains latent in nine out of 10.

HIV, however, changes the equation: Of those whose immune systems have been compromised by HIV, 10 percent will develop active tuberculosis each year, according to the report.

"In today's world, a new TB infection occurs every second. When one considers that much of this transmission occurs in areas with high HIV prevalence, the imminent danger of a global co-epidemic is clear," said Diane Havlir, head of the World Health Organisation's TB/HIV working group.

TB control has been severely destabilised in regions with high rates of HIV, the study says.

In one community of 13,000 people outside of Cape Town, South Africa, the TB patient case load increased six-fold between 1996 and 2004, the researchers reported.

"There has been a staggering increase in TB in this community, and this has been replicated right across southern Africa," Stephan Lawn, a medical researcher at the University of Cape Town, said in a statement.

The report called for urgent coordinated action on the part of governments, researchers, drug companies and local communities.

The measures called for include fast diagnostic tests to detect all forms of TB in HIV-infected adults and children; new methods to rapidly map HIV and TB hotspots; new screening tools to identify new cases of drug-resistant TB; and better equipment for field laboratories in the most affected areas.

There are approximately nine million new cases of tuberculosis in the world every year, according to the WHO. In 2005, the disease killed 1.6 million people.

At the same time, an estimated 40 million people are living with HIV, according to the UN and the WHO. There were 4.3 million new infections in 2006 with 2.8 million (65 percent) of these occurring in sub-Saharan Africa.

In 2006, 2.9 million people died of AIDS-related illnesses.

In South Africa, HIV/AIDS is the leading cause of child mortality and accounts for 40 to 60 percent of all deaths nationwide, according to UNICEF.

Amazing that it could surpass waterborne illnesses & the many other illnesses that beset children in underdeveloped areas.
