In the previous section, I mentioned the superstitions associated with the epidemic occurrence in different decades or centuries. However, with the advancement of scientific innovations and due to rising peoples consciousness, people were also concerned so that any epidemic disease does not outbreak.
During my youthhood in some cholera outbreaks, people used to drink tube well water instead of drinking pond water, as in the meantime tube wells were sunk in some of our localities. But still, some erratic concepts prevailed at that time, such as ‘wash your plate with pond water, not with the tube well water’ as it has to be collected from far away. But in some cases, the conception was very clear. As far I remember, a chicken fox appeared in my youth hood, peoples used to mosquito curtains around the patient so that flies cannot spread around.
It would be wise to write the realities first so as to find the cause of those posts or publicity in FB and the mass media. It may be said that Corona unveiled its face in China since Mid-December of 2019 although its infection was actually initiated some days ahead.
Well, the illness due to corona infection was first felt in Dec 10 in China. It was first unveiled by a Chinese physician Dr. Ai Fen of Wuhan Central Hospital to her colleagues, but no body took the case as serious as it should have been taken. It was published in different mass media that, owing to that ‘disclosure act’ was not chosen by the Chinese authority, instead, she has been detained for taking the ‘disclosure’ as one of the propaganda.
Experts say, if the Chinese government had attended this virus with care at its initial stage, the virus would not have out broken so drastically and the death toll of the China could have been 5% in comparison to the exact death statistics of the present time.
The first identified infected man used to serve in a wildlife market where the wild lives are sold for the consumers who used to eat those. Chinese eat varying types of wild lives such as snakes, caterpillars, rabbits, bats, cats, dogs, and some other wild animals which, most of other nations are not used to.
The first infected’ patient got admitted in the Wuhan Central Hospital and was given proper drugs, but on December 16, doctors came to know that the virus in his body was resistant to flue drugs which are normally used in the cases of other flue related diseases.
On Dec 30, Li Wenliang, a doctor of that hospital suspected it to be one like SARs virus. On the next day, 26 more people, who were associated to that market’s business activities, have also been feeling illness and consequently the market was closed. On January 09, China declared that they have been able to invent the genomic ‘map’ of the virus causing the pandemic disease and on January 14, the country announced that they found no evidence of transmitting this virus from human to human.
But, the virus spread massively in Wuhan along with spreading in three other adjacent cities within January 23. The authority then declared the cities ‘lock downed’. Within January 30, the virus spread throughout the country after the massive observance of China’s ‘Lunar New Year’ holiday - hunting thousands of Chines lives.
Those corona victims became primary hosts or vectors and those spread the virus from one province to another province in China through travelling.
Scientists say that the corona infected persons may show corona symptoms in two to fourteen days. The people having been in contact with the infected people, even before its expression, may also be infected. That is, the disease is infectious. In Wuhan, the virus caused huge human lives. Gradually it spread in the adjacent countries like Singapore, Indonesia, Japan and Malaysia. Form Asia, it then traveled to Europe and has been a havoc or significantly a ‘threat’ in Italy, Iran, Spain, France, United Kingdom, Canada and Germany. It then traveled to some Mediterranean, Middle East and South Asian countries like Saudi Arabia, India, Pakistan and Bangladesh. Up to this date, it took many lives of near about 82 thousands and still in the process of hunting more as on April 07.
