Haiti has launched an emergency cholera vaccination campaign, under which more than 800,000 affected by Hurricane Matthew last month will be vaccinated.

After the category-four storm devastated south-west Haiti, the number of cholera cases across the country rose drastically.

Across the country, the number of new cases went above 200 from roughly 75 a day, reported Npr.org.

To prevent a further surge in cholera cases, the Haitian Ministry of Health and international aid groups plan to vaccinate everyone in south-west Haiti more than one year old.

This campaign is marred by challenges, namely that the vaccine should be kept between 36°F and 46°F until administration and unavailability of electricity poses a huge problem, so the vaccine needs to be carried to places which are difficult to be accessed due to damaged roads.

The World Health Organisation's representative in Haiti Jean-Luc Poncelet was quoted by Npr.org as saying: “There is still a population that is extremely difficult to reach.”

The campaign will provide only a single dose against the normal two doses due to a global shortage of vaccine.

Even though single dose offers less immunity, it will still be effective in stopping the spread of the disease, claimed health officials.

Since 2010, roughly 800,000 people were affected by cholera and more than 10,000 have been killed in the country due to the fatal water-borne disease, reported BBC.

Cholera causes severe diarrhea and dehydration and occurs when human sewage contaminates drinking water supplies.
