HOW CAN A VIRUS BEGIN AND SPREAD

1-KNOWLEDGE :

How can a virus that infects pigs or birds infect people and then begin to spread

Where does it arrive in a country, does it arrive numerous times, or when considering multiple countries, where does it start? If you understand the origins of a pandemic, you'll have a better knowledge of where it came from and may be able to prevent it in the future. It was almost likely bird flu at first, but we also know that the same flu, or something very close to it, was present in pigs at the same time. Perhaps it's someone who works closely with birds or pigs or has some other similar experience. One of the key, unanswered concerns in flu research and public health is: "How does the virus adapt from one species to another, how does the virus adapt from one species to another?"

So mathematical modelers have long been fascinated by the 1918 pandemic, and one of their main goals is to figure out how it moved over the world and what paths it took. You could go backward from perfect data to try to figure out where it came from.

One of the big, unanswered concerns in flu research and public health is: how does a virus adapt from one species to another, for example, how does a virus from pigs or birds get into humans and start spreading?

The crucial question, therefore, becomes: how does the virus adapt within that person to stop it?

2-MATHEMATICAL MODELERS :

So mathematical modelers have long been fascinated by the 1918 pandemic, and one of their main goals is to figure out how it moved over the world and what paths it took. You could go backward from perfect data to try to figure out where it came from. To become a human virus, would you rather be a pig virus or a bird virus? In other words, to be able to transmit from human to human, and it's probably some very quick evolutionary process that's going on within that human, and in many cases, we won't be successful, but in a few cases we will, and that's when the virus can start spreading between humans and become a flu pandemic, before remaining in humans as regular seasonal flu.

It appeared to be fading down just as people were commemorating Armistice Day, but it resurfaced and a far more dangerous and virulent form arose. As a result, the second wave spread like wildfire, infecting a third to a quarter of the country's population the second wave spread like wildfire, impacting a third or quarter of the world's population, and it was short-lived, petering out not long after, perhaps in 1920/1921, but it was short-lived in the sense.

3-SPREAD AMONG HUMANS :

What happened was that the virus continued to spread among humans, in fact, it did so until 1957, and it is likely that the virus adapted to humans.

It wasn't an avian or swine virus that got into people and became more pathogenic by chance.

In a Cambridge lab, we look at both seasonal and pandemic flu from the perspective of how the virus evolves. And how can we predict that evolution and develop vaccines in order to understand what the virus will do next and to develop vaccines against future strains? We can artificially evolve the virus in the lab and on the computer in order to understand what it will do next and to develop vaccines against future strains.
