Awareness is must to prevent dengue
There are innumerous species of insects exist in the world. They are very vital component of nature to support the lives of the world. Some of these species are directly useful and some are harmful to human being. Among the harmful species, mosquitoes are one of the most dangerous, for mankind for its character to transmit diseases like, malaria, filariasis, yellow fever, zika fever, dengue and even claiming deaths in few cases.
Mosquitoes, mainly the male species feed on nectar-sweetened fluid secreted mainly by flowers and other plant juices. Rarely, the female species feed on above as they need proteins obtained from a blood meal in order to mature their eggs. In general, the female species lays eggs on a surface of water and hatch in aquatic larvae. Larvae feed on algae and organic debris. Mosquitoes are attracted to human beings through dry moisture, lactic acid, carbon dioxide, body heat and movement etc. Only the female species are responsible for biting and spreading the disease. The male mosquitoes lack in this particular harm to the human beings.
There are three main mosquito species: Anopheles--the carrier of malaria also transmits filariasis and encephalitis--infection of the brain caused by allergic reactions; Culex--the carrier of viral encephalitis beside filariasis in tropical and sub tropical climates. Aedes--the carrier of pathogens responsible for causing yellow fever, zika fever, encephalitis and dengue. Aedes species, generally lays eggs in flood water, rain pools, stagnant and stored water in any container, flower pots and discarded car-tire casings etc.
The main strategy to control dengue, is to prevent the mosquito from feeding on human beings. The transmission and transfer of the disease can be reduced by the use of an effective mosquito repellent. In recent days Malathion--an organophosphate insecticide is being used to control and kill the mosquitoes besides controlling variety of insects that attacks fruits, vegetables, plants and shrubs. Malathion kills insects by preventing their nervous system working properly. The insect cannot move or breathe properly and so they ultimately die. In human beings Malathion travels to liver and kidneys and affects the nervous system. In general,the body can break down Malathion and eliminate it quickly. Malathion is registered for use in the United States, since 1956.
Use of long clothing that covers arms and legs are advised as safety measure against bite. Above all, mosquitoes breeding and population can be controlled by eliminating the sources of stagnant and stored water either at home or outside. Routine based regular cleanliness drive throughout the year should be conducted by City Corporation and related health departments in association with city dwellers.
Regular campaign and counselling should be conducted for mass awareness with field visit and time to time inspection to ensure a neat and clean environment. Schools, colleges and universities should come up with the policy to keep their campus free of favourable breeding grounds of mosquito, at least once in a month. Documentary films based on the breeding, the growth and the spread of the disease should be produced as a tool to aware general public.
Mosquitoes are specially designed and fashioned little flies-insects that have two wings by the Creator as a valuable source of food for many creatures like frogs, lizards and even some fish that eat mosquitoes. These insects also play an important role in balancing the nature and environment which is still beyond our knowledge. Meantime, these insects are also a special, unique and loyal force of the Creator to punish the inhabitants of a locality, of a nation where corruption, disloyalty, moral degradation spread too much which the holy scripture witness.
Every day, we are to come across such news which is too shocking and disappointing at personal and social level. Even some crimes have crossed the era of Barbarians.
As Muslim, I take the privilege to cite two ayah from two surahs, which may influence our thoughts to realize the mystery behind such an infectious disease which is now out of control and turned epidemic in Bangladesh. Surah Araf, Ayat 133, "So we sent against them the flood and the locusts and the vermins and the frogs and the blood--a succession of clear signs. But they were arrogant and became a guilty folk."
Surah Rome, Ayat--41, "Corruption has appeared through the land and the sea by what the hands of people have earned. So He may let them taste part of what they have done that perhaps they will return to the right path."
It is high time for all of us as a whole to surrender unconditionally to the Creator--Allah Almighty--and repent for our sins, our deeds, if we really did anything wrong, harmful at personal, social or national level, knowingly or unknowingly. This is the holy month of Hajj followed by Eid-ul-Azha and Qurbani--sacrificing cattle in the name of Allah and memorizing Prophet Ibrahim Khalil Ullah.
This is also the month of National Mourning. In this month and on 15th day of August, 1975 we lost the father of the nation and the architect of Bangladesh--Bangabandhu Sheikh Mujibur Rahman and his family members who were assassinated except Sheikh Hasina and Sheikh Rehana, who were abroad. Let we all unitedly pledge to fulfil the dreams of the father of the nation to build a prosperous nation free from corruption and all evils and misdeeds.
Our hearty attempt and good deeds will not only save the nation but it will also save all of us from the curse of nature--the bite of an Aedes Mosquito. As human being, we must meditate of our power, position, proud, arrogance and audacity of being simply helpless and hapless to the single bite of this tiny insect -a miracle of the Creator.
