The cholera that has claimed 57 children under five years of age so far this year is linked to the 2008 cholera epidemic, health officials say.
More than 100000 cases of cholera have been recorded so far this year.
A cholera epidemic in Zimbabwe began in August 2008, swept across the country, and spread to Botswana, Mozambique, South Africa and Zambia.
By January 10 last year, there had been 98741 reported cases and 4293 deaths, making it the deadliest cholera outbreak in Africa in the last 15 years.
The government declared the outbreak a national emergency and requested international aid as the country was incapacitated because of the economic meltdown.
The principal cause of the outbreak was lack of access to safe water in urban areas and communities.
The head of epidemiology and disease control in the Ministry of Health, Dr Portia Manangazira, said the recent outbreak had a direct link to that of 2008.
"So far we have recorded 64 deaths out of 11040 cases in July. It has been discovered that the major cause of this is poor sanitation and water treatment," she said.
Diarrhoea has been severe in areas such as Chimanimani, Chipinge, Chiredzi and Masvingo, Chisumbanje, Bikita, Buhera, Murewa, Mutare and Mutasa.
These areas constitute the bulk of Zimbabwe's irrigation system - and, as a result, water-borne diseases are prevalent there. "Sanitation in the east and southern part of the country is the lowest at 11%. This is very bad and under such conditions disease outbreaks are high," said Manangazira.
Research done at the University of Florida in the US revealed that the 2008-9 outbreak could have been dealt with through massive vaccination to prevent future epidemics.
According to the research, the cholera bacterium is not native to Zimbabwe. Researchers think it was imported from neighbouring nations during the 1970s.
During the 2008-2009 cholera epidemic, nearly 100000 people fell ill and 4300 died. Researchers estimate the majority of those cases were the result of human-to-human transmission.
Researchers looked closely at cultural and other practices that might contribute to the spread of the epidemic.
In order to account for regional differences, the researchers tracked weekly cholera incidence rates for each of the country's 10 provinces.
One practice that stood out was funeral feasts, which are common in Zimbabwe and other African countries. At these feasts, people often eat in a communal fashion, and it is customary to shake hands with the bereaved, who may have been infected as they cared for the deceased under unsanitary conditions.
"The bodies are often transported from towns and cities for burial in the rural areas. Cholera transmission through these types of direct contacts among people accounted for much of the observed illness and also through untreated water," reads the report.
Manangazira said the government was working with a number of partners to contain and treat the cholera.
The US researchers warn that their results indicate that there should be a systematic, regionally based way of dealing with the epidemic.
"The differences observed among provinces suggest that approaches to disease control should be tailored to specific regional characteristics. For example, different areas may require different rates of vaccination to control the disease, potentially resulting in cost savings in less severely affected regions," reads the report.
The Red Cross is involved in delivering immediate assistance in the Chipinge district. Proposed interventions are focused on water and sanitation, health and hygiene in a target population of 30000 beneficiaries.
