Infectivity

Infectivity is the ability of a microorganism to invade the body of a person, animal or plant.

Infectivity characterizes the virulent properties of the causative agent of an infectious disease. The higher the infectivity of a microorganism, the fewer its cells are needed to infect the body.

Infectivity depends on many factors:

1. Type of microorganism. For example, viruses are very highly infective.

2. Microorganism strain. Different strains of the same species can differ significantly in infectivity.

3. Growth phases. In different growth phases, the infectivity of microbes may vary.

4. Environmental conditions. Temperature, humidity, pH and other factors affect infectivity.

5. The state of the host's immunity. With weakened immunity, the infectivity of the pathogen increases.

Infectivity is an important characteristic of the pathogenicity of microorganisms and is taken into account when developing methods for the prevention and treatment of infectious diseases.

Currently, more and more people are faced with infectious diseases that can lead to serious consequences for health and even life. One of the main factors influencing the spread of infectious diseases is the infectivity of the pathogen. Infectiousness is the ability of microorganisms to invade the body of an animal, human or plant to infect them and further spread the disease
