The susceptibility of a host to infections or diseases is influenced by several factors, including the host's immune system strength, genetic predisposition, age, and overall health. Environmental factors such as exposure to pathogens, nutrition, and living conditions also play a significant role. Additionally, behavioral aspects, such as hygiene practices and lifestyle choices, can impact susceptibility. Together, these factors determine how effectively a host can resist or respond to infections.
someone that is exposed to infections disease.
It is infectious.
Organisms are susceptible to viruses when the virus can effectively enter the host cells, replicate within them, and evade the host's immune response. Factors such as the organism's immune system strength, genetic makeup, and prior exposure to related viruses can also influence susceptibility.
Factors influencing a microorganism's capability to cause an infectious process include the microorganism's virulence factors, its ability to evade the host immune system, host factors such as immunity and underlying health conditions, environmental factors like temperature and humidity, and the route of transmission. Genomic variability and antibiotic resistance can also impact an organism's ability to cause disease.
The virulence factor list include capsules, fimbriae, outer membrane proteins, techoic acids, protein A, and m protein. Virulence factors are factors that allow pathogens to avoid host defense mechanisms and adversely affect the host.

A pathogen or infectious agent is a biological agent that causes disease or illness to its host.
Some microorganisms are more infectious than others due to factors such as their ability to evade the host immune response, their mode of transmission, and their efficiency in invading and replicating within host cells. Factors like virulence factors or toxins also play a role in determining the infectiousness of a microorganism.
Virulence is the degree of pathogenicity within a types of parasites. The factors of virulence are the colonization of a niche in the host, immunoevasion, immunosuppression, entry and exit of cells and obtaining nutrition from the host.
