Solid Waste Management and Prevention of
Dengue
Dengue is a major public health problem for past
several decades. It is a mosquito borne disease
and vector-mosquito Aedes prefer to breed in
clear water filled shallow containers in dark,
hidden, cool, peri-domestic environment.
According to the entomological surveys in year
2014 dengue mosquito breeding sites were as
follows and nearly half of the them were related
to solid waste (Figure01)
Figure 01:Entomology Survey Summary- 2014
Solid waste is any solid item which is unwanted,
with no productive use and require disposal. It is
generally known as non-liquid waste, rubbish or
garbage. The sources of solid waste are
households (domestic), commercial
establishments, industries and agricultural
activities. The solid waste that acts as breeding
sites are discarded items such as plastic
containers, tyres, coconut shells, polythene
covers, machinery parts, ceramic items etc.
One of the important strategies in prevention of
dengue is integrated vector management (IVM).
This includes source reduction i.e. removal of
mosquito breeding sites. Therefore, proper solid
waste management (SWM) has a major role in
source reduction and thereby prevention of
dengue.
The principles of SWM are directed at life cycle
approach that includes waste avoidance, waste
minimization, waste segregation, collection
/packaging, transportation, storage, treatment and
disposal (Figure 02).
Figure 02: Solid Waste Management- Hierarchy
The best approach is the avoidance of waste
production and failing which minimize it as much
as possible. Segregation of waste at the point of
generation into different categories is a key
feature of SWM. Implementation of usage of bins
with national colour code would be helpful in
making this exercise a standardised practice
throughout the country.
Ideally, wastes are collected in closed containers
and stored in ventilated rooms where scavenging
is prevented. Transportation is done in close
trucks. Treatment of waste includes composting/
making of bio gas e.g. bio degradable waste,
recycling e.g. glass, paper, plastic and polythene
etc. Waste disposal is done at a purposefully
selected land fill site only and it has to be
dumped, compacted and covered with soil.
If proper SWM is carried out from individual
level to level of local authorities it will have a
significant positive impact on prevention of
dengue as well as on prevention of many other
diseases of public health concern. In addition,
these processes would be helpful in generating an
additional income and contribute towards energy
requirement of the country.
