    A chronic or asymptotic carrier is a term used for a person or any organism that has become infected with a pathogen, but without displaying symptoms or signs of the infection. Although the carrier itself shows no signs of infection, but can transmit it to others or even develop symptoms in later stages of the disease.

    Infection is the replication of organisms in host tissue, which may cause disease. A carrier is an individual with no overt disease who harbors infectious organisms. Dissemination is the spread of the organism in the environment.

    • Summary – Carrier vs Vector

    Diseases are caused by pathogenic microorganisms and infectious particles. Disease transmission occurs through vectors and carriers. Carrier is an individual which has the disease, but not symptoms; it is capable of transmitting the disease to a new individual. Vector is an organism which is capable of transmitting disease from infected individual to new individual without having the disease.This is the key difference between carrier and vector. Both carrier and vector are responsible for disease occurrence and spreading between organisms. CONTENTS 1. Overview and Key Difference 2. What is a Carrier 3. What is a Vector 4. Side by Side Comparison – Carrier vs Vector 5. Summary

    Carrier is an organism which is capable of disseminating the disease to another susceptible organism. Carrier does not show any signs and symptomsof the disease. But the carrier is a diseased organism or an infected individual possessing the potential disease causative agents inside the body. Hence they are capable of transmitting the disease to the next generation. There are main three types of carriers: 1. true carrier, 2. incubatory carrier 3. convalescent carrier Diseased individuals can become carriers even after the cure of the disease. For example, typhoid fever can be again spread through feces and urine of cured people who are carriers. AIDS is a disease caused by HIV(human immunodeficiency virus). There are HIV carriers – individuals do not show AIDS symptoms. However, they are HIV-positive carriers.

    Vector is an organism capable of transmitting a disease from an infected individual to a new individual. The special feature of a vector organism is its capability for passing the disease causative agent from one organism to the second organism without contracting the disease. It acts as a medium for the disease agent to spread and survive in a new organism. Disease transmission via vectors happens in two main ways namely mechanical and biological transmission. During the mechanical transmission, vector acts as a vehicle and transports the disease agent without permitting it to pass important stages of its life cycle such as development or multiplication inside the vector organism. Infectious agents develop and multiply inside the vector during the biological transmission. There are different types of vectors. Many of the human and animal disease vectors are blood sucking insects. Mosquitoes are best-known vectors involved in disease transmission. Other types ofarthropods vectors in...

    Carrier and vector are two types of organisms involved in disease transmission. Carrier transmits the disease without showing the disease symptoms. However carrier contains the disease agents inside. Vector is an organism that transmits the disease but does not become sick. It acts as a vehicle to transport the disease agents from infected to new organism. This is the difference between carrier and vector.

  7. Apr 27, 2017 · Carrier Protein Definition Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell ’s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.

    Typhoid Mary in a 1909 newspaper illustration An asymptomatic carrier is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms. Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease.
