The World Health Organisation (WHO) and UN Childrens Fund (UNICEF) say 43 countries, including Nigeria, now face outbreaks as increasing numbers of cholera cases are reported.
In an issued statement on Friday, the UN agencies said that after years of steady decline, cholera was making a devastating comeback and targeting the worlds most vulnerable communities.
According to Head of UNICEFs Public Health Emergency unit, Jrme Pfaffmann Zambruni, The pandemic is killing the poor right in front of us.
Echoing the bleak outlook, WHO data indicates that by May 2022, 15 countries had reported cases, but by mid-May this year, we already have 24 countries reporting. And we anticipate more with the seasonal shift in cholera cases, said WHOs incident manager for the global cholera response, Henry Gray.
Despite advances in the control of the disease made in the previous decades, we risk going backwards.
The UN health agency estimates that one billion people in 43 countries are at risk of cholera, with children under-five particularly vulnerable.
Choleras extraordinarily high mortality ratio is also alarming. Malawi and Nigeria registered case fatality rates as high as three per cent this year, well above the acceptable one per cent.
South-eastern Africa is particularly badly affected, with infections spreading in Malawi, Mozambique, South Africa, Tanzania, Zambia and Zimbabwe.
The development follows the destructive passage of Cyclone Freddy in February and March this year, which left 800,000 people in Malawi and Mozambique internally-displaced and disrupting healthcare.
These vulnerable communities are at high risk of cholera, a preventable disease in areas affected by heavy rains and floods.
A deadly combination of climate change, underinvestment in water, sanitation and hygiene services and some cases, armed conflict has led to the spread of the disease, agreed the two UN agencies.
Although vaccines exist to protect against cholera, supply is insufficient to face the increasing demand. According to the WHO, 18 million doses of vaccines have been requested globally, but only eight million have been made available.
Increasing production is not an overnight solution, Mr Grays said. The plan is to double the production of doses by 2025, but we wont have enough if the current trend continues.
Not only (do) we need long-term investments, but immediate investments in the water system to ensure access to clean water, sanitation, and dignity, Zambruni said.
To respond to the growing cholera threat, WHO is launching a 12-month Strategic Preparedness, Response and Readiness Plan, requiring $160 million, alongside UNICEFs Call to Action for $480 million.
The combined cholera response plan will cover 40 countries in acute crisis. It will include coordination, infection surveillance and prevention, vaccination, treatment, and water, sanitation and hygiene.
