Indians had not faced many diseases in the past, they were uneducated in how to protect themselves. When an Indian would get sick, they would not isolate that individual like they should have. Instead, they would continuously mingle with the others which caused for the disease to spread rapidly throughout the other members of the tribe.
The most significant cause of death among Native Americans after the arrival of the Conquistadors was the introduction of infectious diseases, such as smallpox, measles, and influenza. The Native American population had no immunity to these diseases, which led to devastating outbreaks and decimated their populations.
Aborigines were subjected to more than two diseases with the start of European settlement. Aboriginal populations were decimated by diseases such as smallpox, venereal disease, syphilis, tuberculosis, measles, and influenza.
they died due to europeans bringing over diseases that the native americans bodies were not adapted to.
Native American populations decreased with the increase of colonial settlements. There are two main reasons for this. First, the Colonists violently attacked the Native Americans, especially the Powhatan Tribes in Virginia and the Wampanoag in Massachusetts. Second, the Colonists brought a number of diseases with them from the Old World that caused epidemics in the Native American populations, especially smallpox.
The Incas and other native American societies were extremely susceptible to European diseases because they had never been exposed to the diseases and so had no herd immunity, allowing the disease to spread rapidly and freely. In Europe the many people that had previously had these diseases were immune, and so could not catch it again, giving the Europeans some degree of herd immunity. Once the disease ran out of easily-available nonimmune people, it could no longer spread..
If by people in America you mean "Native Americans", they had not developed the immunities to European diseases, over the centuries that Europeans had developed. Diseases such as measles, diphtheria, even chicken pox, not to mention smallpox were devastating to the American Indian. It is probable that more Native Americans died of European diseases than died in the many battles with the white man.
The people did not have immunity against the disease
A major threat to the koala populations of Australia is the organism chlamydia, which has four major effects:blindnesspneumoniaurinary tract infectionreproductive tract infections, ultimately rendering animals infertile.Scientists are still working on a cure, as this disease is decimating some of the populations on the mainland.Koalas are also susceptible to leukaemia and skin cancers.

European disease had a devastating effect on the indigenous population of Native Americans. Smallpox, ravaged whole communities and is thought to have been a much more direct cause of the precipitous decline Indian population.
Ferrets are susceptible to a lot of various diseases. The most common is canine distemper. Ferrets are susceptible to feline distemper as well. Ferrets rarely get rabies but precautions should still be taken. There are many other common diseases that ferrets are susceptible to also. Fleas, mites, and physical injuries are not diseases but are quite common.
Perhaps the most devastating result from Spain's conquest of the new world was the radical decline in the population of Native Americas. The Spaniards brought with them a whole host of diseases that the Native American peoples had never been exposed to before. The diseases such as Typhus, Smallpox, Malaria, and Measles wreaked havoc on the Native American populations, killing close to 90% of the population in many areas.

Diseases can lead to social stigma and discrimination, affect relationships and social interactions, and impact mental health and well-being. They can also strain healthcare systems and resources, leading to inequalities in access to care.
A virus does not cause a disease but it will weapon your immune system and make you more susceptible to contracting diseases.
