LUANDA: A yellow fever outbreak in Angola that began late last year has killed 158 people, up from 50 a month ago, as deaths from the disease transmitted by mosquitoes accelerate, a World Health Organization official said on Friday.

There has also been an increase in malaria, cholera and chronic diarrhea in Luanda and other cities, partly due to a breakdown in sanitation services and rubbish collection.

City authorities have slashed their budget for rubbish collection to cope with a budget crisis, leaving piles of waste building up in poorer suburbs including Viana, where the first case of yellow fever was reported in late December. “This is an urban pattern of outbreak of Yellow Fever and it is much more complicated to tackle and deal with,” said Hernando Agudelo Ospina, the WHO representative in Luanda.
