Unlike other ministers who had the luxury of first familiarising themselves with their portfolios as they settle into their new responsibilities, Moyo had to hit the ground running to contain the highly infectious disease, which first broke out in two of Harare's south-western suburbs on September 1.
The government of recently-elected President Emmerson Mnangagwa has declared the latest outbreak a national disaster.
Meanwhile, the outbreak has caused an uproar in the country's political terrain as politicians continue to trade blame over contaminated water and collapsing infrastructure.
The MDC accused the government of using the cholera outbreak, which has claimed 25 lives, to stop the mock inauguration at the party's 19th anniversary celebrations in Harare on Saturday.
Zimbabwe's biggest university said it had postponed a graduation ceremony set for Friday due to the cholera outbreak.
Under former leader Robert Mugabe, who was in power from Zimbabwe's independence in 1980 until being removed from office by the military late previous year, corruption and economic mismanagement were endemic.
"Does the right to life mean nothing at all to this new administration?"
"The current cholera epidemic is a bad outcome of Zimbabwe's failure to invest in and manage both its basic water and sanitation infrastructure and its health care system", Jessica Pwiti, Executive Director of Amnesty International Zimbabwe, said.
This comes in the wake of media reports that the Minister of Health and Childcare, Obadiah Moyo, pushed the outbreak on Harare City Council for failing to provide the city with clean and safe water while neglecting burst sewer systems in Glenview and Budiriro suburds.
"Someone was probably sitting on their job", he said. The police ban triggered an angry reaction from the opposition, which argued that the government was projecting a "holier-than-thou attitude" and targeting its programmes. City officials are in the process of repairing blocked sewers in order to prevent further contamination.
In the capital, long stretches of roads have been reduced to potholed dusty tracks.
Zimbabwe's debt of $11 billion to foreign lenders like the World Bank and Africa Development Bank make it hard to borrow to finance infrastructure development.
