Africa-Press – Cape verde. <\/strong><\/span>Malawi is facing its worst cholera outbreak in two decades. The outbreak started early in 2022 and has, so far, resulted in over 18,000 cases and the loss of 750 lives. It\u2019s also forced the closure of schools and many businesses. Microbiologist Sam Kariuki, who is the director of Kenya\u2019s Medical Research Institute, explains what cholera is and why it\u2019s so hard to control in Africa.<\/p>\n

Why is cholera still such a big issue for African countries?
\nCholera is a disease caused and spread by bacteria \u2013 specifically Vibrio cholerae \u2013 which you can get by eating or drinking contaminated food or water.<\/p>\n

It\u2019s an old disease which has mostly affected developing countries, many of which are in Africa. Between 2014 and 2021 Africa accounted for 21% of cholera cases and 80% of deaths reported globally.<\/p>\n

In several African countries, cholera is the leading cause of severe diarrhoea. In 2021, the World Health Organization reported that Africa experienced its highest ever reported numbers \u2013 more than 137,000 cases and 4,062 deaths in 19 countries.
\nIt has persisted in Africa partly because of worsening sanitation, poor and unreliable water supplies and worsening socioeconomic conditions. For instance, when people\u2019s incomes can\u2019t keep up with inflation they\u2019ll move to more affordable housing \u2013 often this is in congested, unsanitary settings where water and other hygiene services are already stretched to the limit.<\/p>\n

In addition, in the last decade, many African countries have witnessed an upsurge in population migration to urban areas in search of livelihoods. Many of these people end up in poor urban slums where water and sanitation infrastructure remains a challenge.<\/p>\n

Displaced populations \u2013 a major concern in several African countries \u2013 are also very vulnerable to water and food contamination.
\nIt\u2019s important to control cholera because it can cause severe illness and death. In mild cases cholera can be managed through oral rehydration salts to replace lost fluids and electrolytes. Severe cases may require antibiotic treatment. It\u2019s vital to diagnose and treat cases quickly \u2013 cholera can kill within hours if untreated.<\/p>\n

In 2015, it was estimated that over one million cases in 44 African countries resulted in an economic burden of US$130\u2009 million from cholera-related illness and its treatment.<\/p>\n

What\u2019s missing in the response?
\nAfrican governments must acknowledge that the burden of cholera is huge. In my opinion, governments in endemic areas don\u2019t recognise cholera as a major issue until there\u2019s a big outbreak, when it\u2019s out of control. They treat it as a once off.<\/p>\n

The burden of cholera could get worse unless governments put measures in place to control and prevent outbreaks. They need to address water and hygiene infrastructure.
\nThere must also be community engagement. For instance, widespread messaging that encourages hand washing, boiling water and other preventive measures. Community health extension workers are key in getting these messages across and distributing supplies during an outbreak.<\/p>\n

For the most vulnerable populations we must apply oral cholera vaccines. Data on cholera hotspots from surveillance studies will be vital to ensure critical populations are targeted first.<\/p>\n

There are various brands and variation of the oral cholera vaccine, and they are all easy to administer because they are taken orally. They have an effectiveness rate of between 60% to 80% but require a yearly booster. There\u2019s not been a concerted vaccination campaign in many countries, however, because governments are not taking the prevention and control of the disease seriously.<\/p>\n

Finally, the issue of drug resistance needs to be addressed. Drug resistance has made it possible for these cholera strains to stay longer in the environment.<\/p>\n

I was part of a team that conducted a study in Kenya which found that bacteria that causes cholera has become resistant to some antibiotics. Some types of drug resistance are caused by a natural interaction of the Vibrio cholerae bacteria with other drug resistant bacteria in the environment.<\/p>\n

The overuse of antibiotics also contributes to drug resistance. Government agencies should develop ways to monitor the use of antibiotics and restrict their prescription. Regulation of antibiotic use in animals should also be improved. Healthcare workers also need to be trained in the proper use of antibiotics.<\/p>\n

Have there been any recent advances?
\nOne important one has been the development of rapid diagnostic tests that can be used by health workers in the field. These kits are available at costs far lower than lab culture costs. Using them makes it possible to confirm outbreaks promptly so treatment can be initiated.<\/p>\n

In addition, more countries are now adopting the oral cholera vaccine for prevention and control.<\/p>\n

What is lacking is a concerted effort for all endemic countries \u2013 which I consider to be all countries in sub-Saharan Africa \u2013 to have joint measures to tackle cross-border transmission and persistence of cholera outbreaks.<\/p>\n

Some countries are still in denial about outbreaks. This is partly due to fears about repercussions on trade and tourism. But in an interconnected world this attitude isn\u2019t helpful.<\/p>\n

I am optimistic that we can control cholera in African settings. In the short term this could be done through raising awareness among vulnerable populations and interventions like the oral cholera vaccine.<\/p>\n

In the long term African countries need improved water hygiene infrastructure, housing and enhanced socioeconomic conditions. But there must be a strong will by relevant government ministries to work together to realise these goals.<\/p>\n
