Is skin a portal of entry?

A portal of entry is the site through which micro-organisms enter the susceptible host and cause disease/infection. Infectious agents enter the body through various portals, including the mucous membranes, the skin, the respiratory and the gastrointestinal tracts.

What is the main route to spread infection?

The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.

What are the four main classes of microorganism?

microorganisms. The four main classes include bacteria, protozoa, fungi, and viruses.

What are the portals of entry?

The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act. Often, infectious agents use the same portal to enter a new host that they used to exit the source host.

What is an example of portal of exit?

A portal of exit is the site from where micro-organisms leave the host to enter another host and cause disease/infection. For example, a micro-organism may leave the reservoir through the nose or mouth when someone sneezes or coughs, or in faeces.

What are the 4 types of disease transmission?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. The portal of entry is the means by which the infectious microorganisms gains access into the new host.

What happens when pathogens enter the body?

Once you’re infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses. After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.
