WHAT IS A VECTOR?
A vector is a living organism that transmits an infectious pathogen into other living organisms.

VECTORS COMMON TO THE CARIBBEAN VECTORS DISEASES
1. APHIDS
Viral disease in plants
2. RATS
Leptospirosis
3. ANOPHELES
Malaria & Elephantiasis
4. TICKS
Lyme disease
5. HOUSE FLIES
Cholera & Typhoid

HOW THEY TRANSMIT THEIR DISEASES
Houseflies feed on decaying plant and animal materials, garbage, faeces and urine. They then collect germs on parts of their bodies while feeding. These germs are then passed on from one person to the next where these persons who come in contact may become ill with diseases such as typhoid, cholera or dysentery among others.
Mosquitos spread many diseases. The anopheles mosquitoes spread diseases such as malaria or elephantiasis. This is done by the mosquitos feeding on

    It tropical and sub-tropical climates temperature, humidity, and rainfall work together to create a breeding ground for mosquitoes. Mosquitoes are a host for communicable diseases one in particular is called malaria. Malaria is a parasitic disease that infects a particular type of mosquito, Anopheles mosquitoes, which feeds on humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. Although malaria can be a deadly disease, illness and death from malaria can usually be prevented (Global Health - Division of Parasitic Diseases , 2010)…

    Malaria

    Five species of Plasmodium can infect and be transmitted by humans. The vast majority of deaths are caused by P. falciparum and P. vivax, while P. ovale, and P. malariae cause a generally milder form of malaria that is rarely fatal. The zoonotic species P. knowlesi, prevalent in Southeast Asia, causes malaria in macaques but can also cause severe infections in humans. Malaria is prevalent in tropical and subtropical regions because rainfall, warm temperatures, and stagnant waters provide habitats ideal for mosquito larvae. Disease transmission can be reduced by preventing mosquito bites by distribution of mosquito nets and insect repellents, or with mosquito-control measures such as spraying insecticides and draining standing water. A Plasmodium in the form that enters humans and other vertebrates from the saliva of female mosquitoes (a sporozoite) traverses the cytoplasm of a mosquito midgut epithelial cell.…

    The results of experiments and observations of insect biting behavior indicate that when an insect bites a person, it does not inject its own or a previously bitten person's or animal's blood into the next person bitten. Instead, it injects saliva, which acts as a lubricant or anticoagulant so the insect can feed efficiently. Since the pathogens that can cause diseases such as yellow fever and malaria exist in saliva they are transmitted through the saliva during feeding process of bloodsucking insects.…

    A mosquito is an example of an insect that are attracted by decomposing wastes and garbage. They have been found to carry the pathogens that causes dengue and malaria as well as over 40 other bacteria (like salmonella) or viruses that can cause disease. They transfer from garbage to another until it is full and satisfied. Usually, dirt clings to its body which eventually leaves marks on the surfaces it touches. The dirt contains thousands of microbes that are the cause of illness.…

    There are five species of parasites, which infect humans such as Plasmodium falciparum, P. vivas, P.ovale, P.malariae and P.knowlesi. All of these parasites are introduced into our red blood cells by a single bite of the mosquito. The mosquito then injects sporozoites, which are immature forms of the parasite into the bloodstream, and then they pass to the liver, which is where replication occurs, before passing back into the blood and invading the red blood cells. Merozoite is the malaria parasite that raids the red blood cells…
