Botswana has one of Africa's highest economic growth rates. Yet, the country still suffers from high rates of unemployment, poverty and HIV prevalence—having the second highest rate worldwide at almost 24 percent. Botswana also has an exceedingly high number of orphans and vulnerable children. The government has mounted an aggressive response to confront the HIV and AIDS epidemic. Catholic Relief Services works closely with the Catholic Church to support the government's efforts. HIV infection rates are now decreasing. Significant advances have also been made in providing antiretroviral treatment and preventing mother-to-child HIV transmission.
