A
cholera outbreak, which spreads rampantly through infected water sources, is a
real threat post two major earthquakes, which significantly damaged Water,
Sanitation, and Hygiene (WASH) systems and displaced tens of thousands of
people, forcing them to live in congested, poorly constructed areas with
limited access to potable water and sanitation.
These dismal risk factors are compounded by the imminent monsoon
season. Soap, bottled water, water
purification tablets, and oral rehydration tablets alongside cholera
messaging need to be widely distributed to all communities to prevent
outbreaks.
OVERVIEW:
Cholera
is an acute enteric infection caused by the ingestion of the bacterium vibrio cholerae, which is present in
fecally contaminated water or food (4).
Cholera spreads when vibrio cholerae from infected persons' feces
spreads to potable water or food (6).
Cholera is linked to poor access to clean water and proper sanitation
and its incidence is pronounced when basic WASH systems have been damaged or
destroyed (4).
Nepal Specific Considerations:
Cholera
is endemic to Nepal; the first case was recorded in 1823 (1). The majority of reported cases occur during
the monsoon when flash floods and landslides can destroy WASH systems (1). Rural and urban areas are susceptible to
cholera. The most recent outbreaks
occurred in Rautahat in 2014; the deadliest outbreaks occurred in 2009 in
Jajarkot, which affected 30,000 people (1).
Before
the earthquakes, roughly 37% of the population had access to latrines, making
open defecation common practice; if latrines are unavailable, please refer to
the guidance below for cholera prevention practices. Nepali people eat with their hands and in
this environment, it is more important than ever to wash hands thoroughly
with soap before and after eating, preparing food, using latrines,
etc. If soap is not available, scrub
hands with sand or ash and safe water. The
search for survivors is ongoing, and decomposing bodies contaminate water
sources. Therefore it is crucial to
ensure water sources have not been compromised – if you are not sure, it is
better to be safe than sorry, and purify water before consumption. Remote, isolated communities need to be
especially vigilant in protecting water sources; if those have been
compromised, take measures to prevent disease contraction by following
guidelines listed below, and purify water before consumption.
