Is A Susceptible Host Is A Person Who Has Little Or No Immunity To Infection By A Transmitted Pathogen?
Yes, a susceptible host is an individual who has little or no immunity to infections caused by a transmitted pathogen. This lack of immunity can result from various factors, including age, health status, or previous exposure to the pathogen. As a result, susceptible hosts are at a higher risk of becoming infected when exposed to infectious agents.

What is active acquired immunity?
Active acquired immunity occurs when you get an infection by a pathogen (bacteria, virus) and your body responds and removes the pathogen and also your body makes "memory" cells. These cell remember this pathogen and when it enters your body again you remove it immediately. You are now immune to it. You usually don't notice this.
What is the role of immunity in disease in animals?
Immunity is the internal protection of an organism from infection with a pathogen. Therefore, immunity (which is typically conferred by the immune system) has the role of protection against disease in animals. However, another aspect of immunity is innate or species-based immunity. This is conferred by the genetics of the species and protects the animal against pathogens that infect other species of animals. For instance, cattle are not susceptible to PRRS virus infection because PRRS is specific for pigs. This is not true of all diseases, however - viruses such as rabies and foot and mouth disease virus can infect multiple species.
What are two ways that you could acquire active immunity?
Active immunity can be acquired through natural infection or vaccination. In natural infection, the body is exposed to a pathogen, allowing the immune system to respond and create antibodies. Vaccination involves introducing a harmless part or a weakened form of the pathogen, prompting the immune system to generate a protective response without causing the disease. Both methods lead to long-term immunity against future infections by the same pathogen.
What are the two factors that increase the likelihood of contracting infection?
Two key factors that increase the likelihood of contracting an infection are compromised immunity and exposure to pathogens. Individuals with weakened immune systems, such as the elderly or those with chronic illnesses, are more susceptible to infections. Additionally, environments with high pathogen exposure, such as crowded places or unsanitary conditions, significantly elevate the risk of infection transmission.
What does not immune mean?
"Not immune" refers to a state where an individual or organism does not possess immunity against a particular disease or infection. This means they are susceptible to contracting the illness because their immune system has not developed the necessary defenses, either through previous exposure or vaccination. As a result, they may experience symptoms if exposed to the pathogen.
What is vector infection?
Vector infection refers to the process by which a virus or pathogen is transmitted from one host to another through a vector organism, such as mosquitoes, ticks, or fleas. The vector acts as an intermediary carrier for the pathogen, allowing it to be transmitted to a new host during a subsequent bite or feeding. This mode of transmission is commonly seen in diseases such as malaria, dengue fever, and Lyme disease.
What type of immunity may be gained by coming down with a disease?
Acquired immunity: When a person gets sick from a disease, their body produces antibodies to fight off the infection. After recovery, the body retains memory cells that recognize the specific pathogen if it reappears, providing immunity against future infections.
Exposure to a disease-causing organism results in which type of immunity?
Exposure to a disease-causing organism typically results in acquired immunity, either through natural infection or vaccination. This type of immunity is specific to that particular organism and provides protection against future encounters with the same pathogen.
What is the difference between primary and secondary infection?
A primary infection occurs when the body is exposed to a pathogen for the first time, while a secondary infection happens when a different pathogen infects a body already weakened by a primary infection. Primary infections may lead to the development of immunity, while secondary infections can occur in individuals with compromised immune systems.
After a person recovers from an infection why are they usually immune if they are exposed to the pathogen again?
After recovering from an infection, a person's immune system retains memory cells that have been specifically trained to recognize the pathogen. These memory B and T cells can quickly respond to future exposures by producing antibodies and activating immune responses, often preventing reinfection or significantly reducing the severity of illness. This adaptive immune response provides a form of immunity known as "adaptive immunity," which can last for months to years, depending on the pathogen.
