The new corona virus from China posed a threat to global health in the early 2020s. At least 17 people died with more than 600 others positively infected with this disease.Referring to history, this is not the first time that China has become a ground zero, aka the starting point for infectious diseases that eventually become a threat to global health. In 2002, Severe acute respiratory syndrome ( SARS ) infected more than 8,000 people with 774 of them dying.The question arises, what causes China to often experience an outbreak of infectious disease?Reported by the BBC, Professor Mark Woolhouse, epidemiologist of infectious diseases from the University of Edinburgh, Scotland, said there are at least two answers to that question.First, Prof. Woolhouse said that China is a large country with a population of nearly 1.4 billion people. Most of them live in cities with high population density.The second reason, almost all Chinese people, especially those living in densely populated urban areas, have not applied good hygiene standards. The high contact with animals, without adequate security, makes the risk of transmission of disease infections from animals to humans increase.”Not surprisingly the next outbreak occurred in China, or from that part of the earth,” Woolhouse said.Virologist from the University of Nottingham, Professor Jonathan Ball, said the initial suspicion of the new corona virus began in the Wuhan city fish market. Where, marine mammals such as the Beluga whale that is commonly traded in China, have the ability to carry the corona virus.
But do not rule out the possibility, this new corona virus can also come from chickens, bats, rabbits, to snakes that are also traded in the same place.He cited the transmission of SARS, which initially began with bats and then spread to cats before infecting humans. There is also a MERS disease which, before infecting humans, first plague the camel.”Until now no one has managed to find what animal is responsible for the new corona virus. If the cause has been found, then handling it will be easier,” concluded Ball.
