This is a study that is quite Relevant To Bird Flu
Here is a study that should inspire animal workers to mask up for the sake of the animals they say they care for ...
"Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes by UCL researchers".
...This is significant because this means the unmasked farmer who might have bird flu can possibly easily infect a pig with bird flu therefore opening a window of opportunity for more viruses and therefore more dangerous evolving mutations. Its just something people don't talk or think about enough the fact that people give viruses to animals a lot more than animals give people viruses. In other words, an unmasked farmer or veterinarian might be asymptomatic with something and infect the animals they are working closely with. So people that work with animals and livestock need to realize that they make all their animals sick probably more often and more easily than they are aware of.
Some scenarios: Some farmer or veterinarian might be asymptomatic and not even know or feel he/she is sick or maybe what he is sick with doesn't bother him/her at all but will take out the whole flock or prove more serious for the animals he/she is tending to. Another scenario could be a farmer with bird flu infects their pigs and then the pigs mutate the virus down the line back to humans in a form of virus far worse than what the farmer was previously infected with.

Most emerging and re-emerging infectious diseases are caused by viruses circulating in animals. When these viruses cross over from animals into humans, a process known as zoonosis, they can cause disease outbreaks, epidemics and pandemics such as Ebola, flu or Covid-19. Given the enormous impact of zoonotic diseases on public health, humans have generally been considered as a sink for viruses rather than a source, with human-to-animal transmission of viruses receiving far less attention".
