Public health experts say that authorities and Zimbabweans themselves must take care not to spread cholera as the number of reported cases continues to rise.

According to the World Health Organization, the epidemic has claimed 4,011 lives since last August from more 89,000 cases.

This was also emphasized as thousands gather for a memorial service on Tuesday honoring Susan Tsvangirai, the late wife of Prime Minister Morgan Tsvangirai, killed in a highway crash.

Many thousands are expected to converge on Glamis Arena, an outdoor venue in the Harare Showgrounds, and on Wednesday in Buhera, Manicaland province home town of both Morgan and Susan Tsvangirai, to bid farewell to the woman now called the mother of the nation.

Susan Tsvangirayi was killed on Friday in a highway collision between the Toyota Land Cruiser in which she and her husband were traveling, and a truck which veered into their lane.
