The City of Cape is urging residents to continue hand washing to maintain hygiene standards - despite water shortages.

Cape Town - Officials from the City of Cape Town appealed on Monday for residents to be vigilant against health risks caused by efforts to save or reuse water as the city's drought worsens.

Cape Town is grappling with a listeriosis outbreak and a doubling of typhoid cases in the past year.

It has now urged residents to continue hand washing to maintain hygiene standards - despite water shortages.

"This is the season where the germs have a way of propagating and spreading," the city's health manager, Virginia De Azevedo, told a press briefing.

"We are talking faecal-oral contamination of the water, the food and the hands... In the health facilities, we are all on alert."

De Azevedo warned that hand sanitiser gels were often an inadequate substitute for hand-washing with potable water.

"You can still wash your hands without wasting water," she said.

Capetonians have been urged to use just 50 litres of water per day in an effort to delay the arrival of "Day Zero" when most residents will have their taps shut off.

After "Day Zero", currently forecast for April 16, many of the four million residents will be forced to queue at some 200 sites for a daily allocation of 25 litres.

Health officials also warned that residents could be putting themselves at danger by trying to purify dirty water, not boiling natural spring water before consumption and using untested boreholes.

"If they are taking water from the springs they must boil it or use purification tablets," said De Azevedo.

"The public must be aware of what are the water sources that are safe."

"We are aware that cholera is a very big threat and that typhoid is a very big threat," she added, referring to other parts of the words that have also suffered chronic water shortages.
