Study Finds ‘Striking’ Differences in Rates of HIV/AIDS within Ethiopia, Africa
ADDIS ABEBA – Despite the rapid scale-up of antiretroviral therapy (ART) since 2000, HIV/AIDS is still the most common cause of death in sub-Saharan Africa, according to data from the Global Burden of Disease.
In Ethiopia, GBD data show that HIV/AIDS was responsible for 17,181 deaths in 2017.
The new scientific paper reveals striking variation in HIV prevalence at provincial and district levels and published in Nature.
It provides precise geographic estimates of HIV prevalence and numbers of people living with HIV to identify priority areas for health care support to reduce the burden of HIV.
The study is the first to map HIV prevalence among adults ages 15-49 comprehensively at a granular, sub-national level for all 47 countries in sub-Saharan Africa.
The results show a high variation in prevalence and changes in prevalence over time within countries.
In 2017, the highest estimated HIV prevalence at the second administrative level in Ethiopia was 3.5% in Majang Zone.
The lowest prevalence was 0.3% in Dawro Zone.
The study found that the largest number of people aged 15-49 living with HIV (PLHIV) reside in Addis Abeba.
Since 2015, the World Health Organization has recommended ART for all people living with HIV, because early treatment enables them to live longer and healthier lives and reduces the potential for transmitting the virus.
Despite the rapid scale-up of ART, 34% of people in East and Southern Africa and 60% of people in West and Central Africa living with HIV are not currently on treatment, according to UNICEF.
Growing population size and continued high incidence of HIV infection, combined with increased life expectancy among people living with HIV (PLHIV), has led to an increase in PLHIV in sub-Saharan Africa.
Between 2000 and 2017, the number of people aged 15-49 years living with HIV in sub-Saharan Africa increased by 3 million, even as HIV prevalence declined.
“Changing the trajectory of HIV/AIDS in Africa requires that we continue to seek better ways to know the epidemic,” said Dr. John Nkengasong, director of the Africa Centers for Disease Control and Prevention (Africa CDC).
“This paper will support policymakers and health care providers in locating hotspots of HIV/AIDS at national and subnational levels, and will help guide the smart investment of scarce resources for diagnosis, prevention, and treatment,” he said.
