As monsoon season is at its peak, increase in rainfall , frequent disruptions in garbage collection, inadequately treated water supply and maximum consumption of street food make Kathmandu a fertile ground for waterborne diseases like cholera.
According to the World Health Organization, inadequate access to clean water and sanitation facilities in economically deprived habitats is the main reason behind the outbreak of cholera. Therefore, crowded urban habitats, slums, camps for internally displaced persons or refugees are the principal areas for cholera outbreaks.
Cholera is an acute diarrheal infection caused by the ingestion of food or water contaminated with the bacterium Vibrio cholerae. Generally it takes between 12 hours to 5 days for a person to develop symptoms after being infected. Cholera affects both children and adults, which leads to death if not treated within hours. However, some do not get to this deadly stage as they develop mild or moderate symptoms which can be treated with oral rehydration solution. More severe cases need rapid treatment with intravenous fluids and antibiotics.
WHO recommends implementing Oral cholera vaccine campaigns for the prevention of large scale cholera infections. Last year, in November, after infection spread over a thousand in Nepal, the Ministry of Health and Population had decided to run a vaccination drive for cholera prevention in the most affected areas. WHO provided 252,363 doses of oral cholera vaccines for the purpose.
The cases of cholera have been appearing consistently in Nepal, which makes Nepal a cholera endemic country. “Regarding best preventable measures for cholera outbreak, the proper use of latrine and water soap for hand washing and drinking chlorinated piped drinking water are to be applied, however boiled water is the best for drinking according to health experts,” says health expert and instructor Barsha Raut, at the Epidemiology and Disease Control Division (EPCD) call center Kathmandu.
To safely manage the possible cholera outbreak among a large mass of the population, the Ministry of Health and Population has directed hospitals across the country to be prepared for a health emergency. “There is a considerable amount of ignorance regarding cholera among the valley population as it is considered to be a disease that occurs only in rural areas,” says Raut.
At present, taking precautions is of extreme significance especially for people living in crowded habitats in the city. Drinking fully boiled drinking water, adopting healthy sanitation practices and avoiding poorly cooked food outside as much as possible are the primary steps to be taken by the public.
