How does a virus in a city in China end up going to every continent?

And messing up everyone's lives?

    From people traveling across the globe and spreading it without knowing it. About half of the people who get the virus are asymptomatic meaning they carry to others and yet have no symptoms of it themselves

    Depends on the virus.  SARS was believed to be carried by migratory waterfowl.  Ordinary flu is person-to-person, so it's by someone leaving or returning from an infected area.

    Wuhan is a major city with population of over 11 million.  (By comparison, the population of New York City, the largest city in the US, is about 8.5 million.)  Before the Chinese Government shut down all travel in and out of the Hubei Province, the Wuhan Tianhe International Airport handled 24.5 million passengers a year.  International destinations served  from the airport include Kuala Lumpur, Singapore, Tokyo, Hong Kong, Dubai, Istanbul, Paris, London, Rome, Moscow, Seoul, New York, and San Francisco, just to name a few.  An infected person can travel literally halfway around the world in just 12 hours.

    A person can be infected but not show any symptoms of the disease for as long as fourteen days.  The local authorities in Wuhan were slow to react at the start of the epidemic and people infected with the virus were able to travel literally all over the world.  An infected person cooped up for 4 to 12 hours on a plane will spread the virus to the nearby passengers, who then will unwittingly spread it to everybody they come into contact with, and so on and so on.

    Passenger aircraft.  It can be anywhere on Earth in 24 hours or less.  But I believe Antarctica is still in the clear for now.

    In 1920, the only location without the deadly "Spanish flu" was American Samoa.  They turned away ships, and no aircraft came near that distant island.

    • Maybe the virus came from melting glaciers.

    People spread the virus when they travel.

    In the 21st century mankind is very mobile. We fly hundreds of thousands of people from nation to nation every day. We ship boat-fulls of people around the world to stopover in ports of call daily.

    And some of those millions each day were carrying the COVID19 virus.

    That's how.

    China was the first victim of the virus. Sociopaths often find a way to blame the victim. It called gaslighting.

    International travel combined with the fact that most people who get it don't get sick and realize they're infected.

    • Covering cough is standard expectation. Coughs are also caused by different reasons.
