What if the first ones that travel to Mars come back with a Virus, will it spread across the world as Covid-19 did ?

I bet it does....

     that would prove life exists on mars,and that would be a HUGE step forward in knowledge

    And nobody would care much if it DID spread so long as the majority survived

    Any virus can spread across the world.

    A virus from Mars might not survive on Earth long enough to infect anyone.

    A virus is an obligate intracellular parasite. It cannot survive without a host. Mars is devoid of life; therefore, there is nothing on Mars for viruses to infect. Consequently, there are no viruses on Mars. You cannot have viruses without living organisms. Astronauts will not be infected by what does not exist.

    Well, the trip home will take 6 to 9 months;  I'm sure they'll take people adept in medical procedures - and, in that time, we'll find out if they've been infected with anything or not.  

    The first few missions to return from the moon took some precautions - isolating the astronauts & recovery team for 3 weeks - and, since the trip back from Mars will take such a long time, we'll know if there's a problem or not.

    That would require a virus to be able to latch onto receptors it had never encountered, and have a genetic code compatible with life here, on nucleic acids very similar to those found here.  It isn't going to happen.  It is possible that someone would have an immune reaction to a microörganism found on another planet, but it would be unlikely to spread.

  • After the first moon landings, the astronauts were kept in isolation for three weeks for that very reason. However, it's unlikely an astronaut would pick up any kind of extraterrestrial bug since they have to wear isolation suits outside of the spacecraft.  With our present technology, the journey to and from Mars will take about 2 years each way.  If the astronauts have picked up any form of disease that's threatening to humans, it will have become obvious long before they get back to Earth.

    How could there be a virus on Mars and even if there was how would it infect people on earth?  A virus is specific to a limited number of hosts that have the same type of cells and genetic machinery.  A virus is the least likely pathogen to fear from space.

    Yes, then aliens will take over our bodies and turn us into zombies.
