Why Coronavirus Spread In China – Free PDF Download

 

CHINA THE HOME OF VIRUSES

  • Several deadly new viruses in recent years have emerged in China —  Severe Acute Respiratory Syndrome  (SARS), bird flu, and now the novel  coronavirus (nCOV).

ZOONOTIC INFECTIONS

  • A zoonosis (plural zoonoses, or zoonotic diseases) is an infectious disease caused by  bacteria, viruses and parasites that spread  between animals (usually vertebrates) and

DANGER OF ZOONOTIC VIRUS

  • The Justinian Plague (541-542 AD), the Black Death (which started in Europe in 1347), yellow  fever in South America in the 16th century, the  global influenza pandemic in 1918, and modern  pandemics such as HIV/AIDS, SARS, and triple-  reassortant A H1N1 influenza have one thing in  common: the causal organisms came to humans  from animals.

DEATH TOLL OF THESE VIRUSES

  • The Black Death is estimated to have killed 30% to 60% of Europe’s population.
  • Yellow fever killed thousands

WHO WARNING

  • The World Health Organisation (WHO) estimates that globally, about a billion cases of illness and millions of  deaths occur every year from zoonoses, i.e, diseases  and infections naturally transmitted between people  and vertebrate animals.
  • Some 60% of emerging infectious diseases globally are Of the over 30 new human pathogens  detected over the last three decades, 75% originated in  animals.

REASONS

  • Wherever there is close mixing of humans and animals, especially the unregulated  handling of blood and other body products, as  happens for example in China’s animal  markets, there are greater chances of  transmission of a virus from animals to  humans, and its mutation to adapt to the  human body

DR K S REDDY,  FORMER PROFESSOR  OF AIIMS AND  PRESIDENT OF THE PUBLIC HEALTH FOUNDATION OF INDIA (PHFI)

  • “Proximity to animals grows from wild food markets and captive animal breeding, with deforestation creating a conveyor belt for  viruses and vectors to move from wildlife to captive animals, and  from them to humans.The wild food markets in China offer  both a mix of many animals which harbour deadly viruses, and  an opportunity to transmit with ease to crowds of humans  whose taste for a diversity of wild as well as close-bred animals  provides a conveyor belt for animal-to-human transmission.
  • Once the virus gains entry into humans who travel and transport animals, the infection spreads,” Dr Reddy said.

ECOLOGY OF INFECTIONS

  • With a population of nearly 1.4 billion and 50% of the world’s livestock (livestock – any animals kept for use or profit)

AMERICAN WARNING

  • China’s ecology poses a risk for emerging, re-emerging, and novel diseases that could  threaten China and the rest of the world,  says the US federal agency Centers  for Disease Control and Prevention  (CDC).

FUTURE THREATS

  • Bill Gates even wrote in 2017 that he considers a deadly pandemic to be one of the world’s three biggest threats, next to  climate change and nuclear war.
  • “In the case of biological threats, that sense of urgency is lacking,” Gates said in a presentation the following year. “The  world needs to prepare for pandemics in the same serious way  it prepares for war.”
