Differbetween
A carrier can transmit disease to another organism without showing any symptoms which is an infected organism eg: HIV carriers whereas a vector is an organism in which the disease is transported from an infected person to a healthy person.

What is the difference between vector and vehicle?
Vector transmission occurs when a living organism carries an infectious agent on its body (mechanical) or as an infection host itself (biological), to a new host. Vehicle transmission occurs when a substance, such as soil, water, or air, carries an infectious agent to a new host.
What is the difference between host and carrier?
Carriers: hosts without obvious illness
The person or animal infected can potentially spread the pathogen, but does not show clear symptoms (8). The symptoms may be mild, or may be completely absent. These hosts are called carriers, or asymptomatic carriers.
Can a human be a vector?
But what about humans: Can we humans be vectors? Technically, sure, says Aiello. But Monto says he probably wouldn't use the word to refer to humans. "To me vector is usually an arthropod [insects and other animals with exoskeletons]," Monto says.
What is a carrier of a disease?
As noted earlier, a carrier is a person with inapparent infection who is capable of transmitting the pathogen to others. Asymptomatic or passive or healthy carriers are those who never experience symptoms despite being infected.
What are the 4 major disease vectors?
Disease vectors
- Malaria (protozoan): Anopheles species of mosquito.
- Lymphatic filariasis (nematode worm): Culex, Anopheles, Aedes species of mosquito.
- Dengue (virus): Aedes species of mosquito.
- Leishmaniasis (protozoan): mainly Phlebotomus species of sandfly.
What are the 6 modes of transmission?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle.
What diseases are asymptomatic?
Examples of asymptomatic illnesses
- Hypertension (high blood pressure)
- Hepatitis B and C.
- Herpes simplex virus (HSV)
- Type II diabetes.
- Glaucoma.
- Osteoporosis.
- Respiratory diseases, like the flu or COVID-19.
Is a vector a carrier?
A carrier can transmit disease to another organism without showing any symptoms which is an infected organism eg: HIV carriers whereas a vector is an organism in which the disease is transported from an infected person to a healthy person.
What are the 5 methods of disease transmission?
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 do humans use as vectors?
Mosquitoes are the best known disease vector. Others include ticks, flies, sandflies, fleas, triatomine bugs and some freshwater aquatic snails. Diseases transmitted by vectors include: malaria, dengue, Zika virus, Chagas disease, human African trypanosomiasis, schistosomiasis, Chikungunya, Rift Valley fever.
Is Ebola a vector borne disease?
Additionally, Ebola virus is not known to be transmitted through food. However, in certain parts of the world, Ebola virus may spread through the handling and consumption of wild animal meat or hunted wild animals infected with Ebola. There is no evidence that mosquitoes or other insects can transmit Ebola virus.
Is malaria a virus?
Q: Is malaria caused by a virus or bacteria? A: Malaria is not caused by a virus or bacteria. Malaria is caused by a parasite known as Plasmodium, which is normally spread through infected mosquitoes. A mosquito takes a blood meal from an infected human, taking in Plasmodia which are in the blood.
