Lusaka - Zambian President Edgar Lungu has directed the military to help fight the spread of cholera, which has killed 41 people in the nation's capital and made more than 1 500 others sick since late September.
The outbreak began on September 28 but appeared to die down by October 20, with fewer than five patients reported weekly until November 5. The number of cases then surged, with 136 in the week beginning Nov. 26, the World Health Organisation reported.
Presidential spokesman Amos Chanda said in a statement late on Friday that the president believed emergency measures were needed to contain the waterborne disease, including the closure of some markets.
The outbreak was initially confined to densely populated parts of Lusaka where poor sanitation can aid its transmission, but the disease had now spread to low density areas, Chanda said.
"The president is deeply concerned at rampaging advance of the epidemic and has therefore called on the defence forces to join other stakeholders ... and thoroughly clean up Lusaka," Chanda said.
The outbreak was initially linked to contaminated water from shallow wells but investigations revealed that the spread was being propagated through contaminated food, he said.
"In the last two weeks, three traders from Soweto market have died from cholera and 18 are currently under admission in cholera treatment centres," Chanda said, referring to Zambia's largest market.
Chanda said all markets, bars, restaurants and other public places that pose a risk of further transmission of cholera would be closed until they met hygiene standards.
Cholera is spread by ingesting faecal matter and causes acute watery diarrhoea. It can be treated with oral rehydration solution but the disease spreads rapidly and can kill within hours if not treated.
