Based on speculation by the Nigerian government, they believe it is chemical poisoning. But by definition, chemical poisoning should not have the characteristics of human-to-human transmission, and there is no confirmation of what kind of virus it is. The government has given warning of an outbreak of an unidentified disease, in which patients suffer from vomiting, diarrhea, and swelling of the body. The case, which first appeared in Benue state, south of the capital, is less than a week old and already 104 people have been confirmed infected, with 15 patients infected and dying within 48 hours, while having human-to-human transmission properties. The Nigerian outbreak of the disease has come more aggressively and caught people off guard than the outbreak of the new coronavirus in Wuhan.
Initial tests of the disease showed it was neither Ebola nor Lassa fever. As of Feb. 12, the death toll from the virus had risen to 47 people. What's most frightening is that the earliest people infected with the virus all died within 48 hours, a very rapid death toll that can't help but make people nervous. According to a preliminary investigation recently released by the city's health organization, non-viral and bacterial infections of this mysterious disease can basically be ruled out.
The speculation is that it may be pesticide poisoning, the same as the previous note issued by the government, as chemical poisoning. But what is puzzling is that chemical poisoning does not usually lead to human-to-human transmission, whereas this mysterious virus is transmitted by breath, saliva, sweat and so on. And take Nigeria, the most populous country in Africa. Its itself does not have very good sanitary conditions, where it is summer all year round, and the way to dispose of garbage over there is by incineration, and as a place where the living conditions themselves are very poor, the average life expectancy of human beings is not long.
And with the resulting outbreaks of disease and medical care that can't keep up, the situation in Nigeria is described as crisis-ridden .
