no hey can give you flu
No, head lice are specific to humans and cannot transfer to dogs or cause infestations in them.
Cowpox is believed to have originated from rodents or other small mammals in Europe. It was first identified in cows and then transmitted to humans during the process of milking, leading to the vaccine development by Edward Jenner in the late 18th century.
Edward Jenner used it to help create a vaccine for smallpox
because they get cold just like humans.
Cowpox was probably known as long as people have had domesticated cattle. However the observation was not made until the late 1700s that infection with cowpox from working with cattle infected with cowpox prevented infection with smallpox. This observation eventually led to the introduction of safe vaccination (using cowpox pus taken from cattle) to replace often hazardous variolation (using smallpox pus taken from humans).
vaccination, from the latin word vaccina (cow). because he used an extract from cow pustules, not human pustules as others had tried earlier. cowpox and smallpox are close enough related to cause crossimmunity, but cowpox can't infect humans.
A cowpox pustule is a localized skin lesion caused by the cowpox virus, which is a member of the Orthopoxvirus genus. It typically appears as a raised, fluid-filled blister that can develop crusts over time. Historically, cowpox was significant in the development of the smallpox vaccine, as exposure to cowpox conferred immunity to smallpox. The disease primarily affects cattle but can also infect humans, usually through contact with infected animals.
Yes, head lice are specific to humans and cannot infest dogs. Dogs can get their own type of lice, but it is not the same as head lice and does not pose a threat to humans.
It can bring about that problem in humans so I suppose the same probably can apply to dogs.
Cowpox, a skin disease caused by the cowpox virus, is a naturally-occurring phenomenon and was not invented by humans. However, the cowpox virus was used by English farmer Benjamin Jesty and German teacher Peter Plett in 1774 and 1791, respectively, to synthesize a vaccination for the much more dangerous smallpox. The word "vaccination" however, would not be coined until 1796, by English physician Edward Jenner.
Cowpox helped find a vaccine to small pox
There are more humans than dogs.
