Diseases are an agent of selection. Exposed animals that survive the disease process are the ones that live to reproduce. Individuals that succumb are removed from the gene pool. The mechanism of survival could be a more robust immune system or mutation(s) that is/are inherently immune for reasons other than immune response.

How does selection affect natural selection?
Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
How does natural selection affect survival?
Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
Should there be a cure for every type of disease?
No, there should not be a cure to every disease. Natural selection is a basic function of life, and often disease is part of that natural selection. Imagine the population explosion of humans if we could cure all disease? If we weren't dying from disease, then we'd be dying from famine.
What other theories are there except for natural selection?
Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.
What are the three ways natural selection can affect the distribution of phenotype?

How does Evolutionary Trends affect Natural Selection?
Adaptation for stronger shells.
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
