In Colonial America, local doctors, midwives, healers and even officials administered medical care to the residents in their village or town. [2] There was no distinction between physicians and surgeons; when an emergency occurred the person who was responsible for administering medical care was expected to handle all aspects of the problem.

Calculating the infection rate is used to analyze trends for the purpose of infection and disease control. [1] An online infection rate calculator has been developed by the Centers for Disease Control and Prevention that allows the determination of the streptococcal A infection rate in a population.
The American era of limited infectious disease ended with the arrival of Europeans in the Americas and the Columbian exchange of microorganisms, including those that cause human diseases. European infections and epidemics had major effects on Native American life in the colonial period and nineteenth century, especially.
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
The colonization of the United States resulted in a large decline of the Native American population primarily because of newly introduced diseases. [3] A significant percentage of the Native Americans living in the eastern region had been ravaged by disease before 1620, possibly introduced to them decades before by explorers and sailors ...
Europeans suffered higher rates of death than did people of African descent when exposed to yellow fever in the Americas, as numerous epidemics swept the colonies and sugar plantations. [ 59 ] On the other hand, European exploration of tropical areas was aided by the New World discovery of quinine , the first effective treatment for malaria .
In epidemiology, force of infection (denoted ) is the rate at which susceptible individuals acquire an infectious disease. [1] Because it takes account of susceptibility it can be used to compare the rate of transmission between different groups of the population for the same infectious disease, or even between different infectious diseases.
Colonization comprises the physical arrival of a species in a new area, but also its successful establishment within the local community. In ecology, it is represented by the symbol λ (lowercase lambda) to denote the long-term intrinsic growth rate of a population. Surrounding theories and applicable process have been introduced below.
