Infectious Diseases
Overview
Infectious Diseases the invisible enemies
The infective agent begins to thrive and multiply throughout the body (Broemeling, 2021). Its proliferation can be fast or slow depending on the type of organism. Every infectious disease has an incubation period, the length of time the pathogen is established until appearance of symptoms of the disease.
Factors influencing infection
- quantity of invading germs (dose of the infection)
- the virulence of the infection
- the condition of the body’s immune system
- contact with source of infection for contagious diseases
Microorganisms adapt far more rapidly than humans as the scene shifts. A bacterial generation ranges from 20-30 minutes, for viruses it’s much smaller.
Who is going to adapt to whom?
Virus means poisonous substance ranging from 20 to 400 nm in diameter can be observed only with a electron microscope. Outside of a living cell is a dormant particle of strange shapes. When manage to get inside the cell it starts replicating killing the cell or skewing its functions.
