This outer structure helps the molecular machinery of the virus break through cellular membranes and hijack our cells.
If you dry the virus out in air, it keeps its stability.
In either method, the actual process of destroying the virus happens in just a second or two.
Even though both approaches are similarly effective at killing the virus, soap and water has two benefits: first it washes away any dirt which could otherwise hide virus particles.
For almost a decade, scientists chased the source of a deadly new virus through China’s tallest mountains and most isolated caverns.
The virus in question was a coronavirus that caused an epidemic of severe acute respiratory syndrome, or SARS, in 2003.
When an infected person coughs, droplets containing the virus spray out.
The virus can infect a new person when the droplets enter their nose or mouth.
Cold weather keeps their delicate casing from drying out, enabling the virus to survive for longer between hosts, while UV exposure from sunlight may damage it.
But because no one is yet immune to a new virus, it has so many potential hosts that it doesn’t need ideal conditions to spread.
In the body, the protein spikes embed in the host’s cells and fuse with them— enabling the virus to hijack the host cell’s machinery to replicate its own genes.
So when an RNA virus replicates, it’s much more likely to have mistakes called mutations.
But some make the virus better suited for certain environments— like a new host species.
Epidemics often occur when a virus jumps from animals to humans.
Once in humans, the virus still mutates— usually not enough to create a new virus, but enough to create variations, or strains, of the original one.
But mutations can make a virus less recognizable to our immune systems— and therefore more difficult to fight off.
They can also make antiviral drugs and vaccines less effective, because they’re tailored very specifically to a virus.
That’s why we need a new flu vaccine every year— the influenza virus mutates so quickly that new strains pop up constantly.

I was very fortunate when the ILOVEYOU virus came out, because the first person I received it from was an ex-girlfriend of mine.
So, we are suggesting a strategy that's based on a weak spot based on the biology of the virus, which is a cycle of work and lockdown.
It exploits the vulnerability of the virus in that, when a person gets infected, they're not infectious for about three days.
Also, just working four days out of two weeks restricts the amount of time the virus gets to see many other people, and that's a very powerful effect.
Several months ago a highly infectious, sometimes deadly respiratory virus infected humans for the first time.
Without time to study the virus, doctors know little about how to save their patients, and hospitals reach peak capacity almost immediately.
Somewhere in the range of millions to hundreds of millions of people die, either from the virus or the collapse of health care systems.
Around this point herd immunity kicks in, where the virus can no longer find new hosts.
This time, governments and communities around the world slow the spread of the virus to give research facilities time to produce a vaccine.
Even with these measures in place, the virus slowly spreads, causing up to hundreds of thousands of deaths.
Once 40-90% of the population has received it— the precise amount varying based on the virus— herd immunity kicks in, and the pandemic fizzles out.
