Malaria Mosquitoes Can Transmit Malaria

Malaria is a disease characterized by fever and flu like illness that according to the CDC “if not treated can lead to jaundice, kidney failure, seizures, mental confusion, coma, and death” (CDC p.2. There are four types of malaria: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae with the most common type being plasmodium falciparum. (CDC p.1) ).. This disease can only be transmitted by an interaction of blood as the parasite lives in the red blood cells of the infected host individual. This can be due to blood transfusions, sharing of syringes or by its common vector, the Anopheles mosquito.Because of its vector being a mosquito malaria is common in areas with warm temperatures and causes the most damage in poor developing

Malaria infection is caused by parasitic protozoan plasmodium. Several species of malaria parasites exist but the most fatal known is plasmodium falciparum. It enters the liver and replicates itself by getting into the red blood cell and ripping its way out when fully matured. It was once thought that the US military got close to completely eradicating the vector mosquito through DDT (dichlorodiphenyltrichloroethane) and the parasitic plasmodium with vaccines until they discovered that both are capable of mutating and gained the ability to be resistant to any chemicals scientists could produce (Horizon, 2005).

This mode of transmission, like malaria, can leave the host deadly sick. Its a cycle, with the parasite in the host, a mosquito will carry the blood with the parasite and inject it into a different host.

The lifecycle of a heartworms begins when a female mosquito ingest blood containing microfilariae from a heartworm infected animal. Inside the body of the mosquito, the microfilariae develops into first stage larvae (L1) and then undergoes two more process to develop into third stage larvae (L3) of which is the infective stage. Depending on the temperature, this development process can take between eight and thirty days. At this point, when the infected mosquito attaches to a cat and feeds on its blood, the third-stage larva is transferred into the mosquito bite wound. Within three days of entering the cat, the L3 molt to the L4 stage in the tissues and muscles that lay just below the skin of the cat. After about two months of migrating through the muscles and tissues, the L4 undergoes a final development into immature adult heartworms. Seventy to ninety days post infection, the immature adult heartworms then enter a peripheral vein and are carried by the cat’s blood circulation system to the caudal pulmonary arteries. This is where the majority of heartworms are cleared from the cat due to a mass immune response, but a few may continue development into adults. Once the heartworm develop into adults, they invade the heart first and then spread to other organs in the body and cause

Malaria, on the other hand, was far off more deadly then Yellow fever for it consisted of parasites (Malaria). An engineer once quoted “If we could control malaria, I would be less anxious about other diseases. If we cannot control malaria, our mortality is going to very heavy” (American Canal Construction). Consequently, these infections developed in mosquito salivary glands as well and reproduce in the liver (Malaria). Above all, this incubation period could last for months to a year at a time (Malaria). When the parasites leave the liver they reenter the bloodstream where they are able to infect red blood cells to reproduce once again until the cell bursts (Malaria). As a result, it caused anemia and jaundice from the lack of blood cells (Malaria). Other symptoms include seizures, confusion, coma and death (Malaria).

It is caused by a parasite that infects certain mosquitos that feed on humans. People infected with malaria usually suffer from high fevers, shaking chills, achy muscles, headaches, tiredness, and flu-like illness. It may also cause jaundice and anemia. The malaria parasite is found in the red blood cells of a person which means it can be transmitted through blood transfusions, organ transplants, or the shared use of needles syringes contaminated with blood. Malaria is not contagious; it cannot be transmitted from one person to another. Some parasites can remain dormant in the infected person’s body for up to four years after they are bitten. When the parasite comes out of hibernation and begins to invade the red blood cells, the person will become sick.

The most common way this disease is transmitted from one animal to the next is through mosquitoes. A mosquito carrying infective heartworm larvae bites a dog and transmits the infection to them. The larvae grow, develop, and migrate in the body over a period of 6 to 7 months, in which time they become sexually mature male and female worms. this is the prepatent period. The worms then reside in the heart, lungs, and associated blood vessels. The worms begin to mate and release microfilaria into the blood

Mosquitoes pass malaria to humans through their salivary glands. Once the parasites have entered the blood stream, they go to the liver. In the liver they mature and undergo reproduction, forming merozoites. These merozoites enter the blood stream and inject themselves into red blood cells. Once inside the blood cells, they reproduce rapidly and within forty-eight to seventy-two hours, the blood cell bursts, releasing hemoglobin into the blood stream. It is the destruction of these blood cells and the hemoglobin released into the blood stream that actually causes most of the symptoms.

By getting the virus from a bite the mosquito must already be infected itself. There are studies currently happening trying to figure out how long exactly does the virus stay inside the semen and vaginal fluids of those who are infected, also being studied is how long it can be passed to their partners. Although the U.S. hasn't seen any cases of the disease being transmitted by blood transfusion it has been seen in other places in the world. An example would be the French Polynesian outbreak, around 2% of those donating blood tested positive for Zika however, in previous outbreaks the virus was also found. Just one case in the United States shows of someone getting ill through a laboratory yet, prior situations show four cases of someone getting the virus in a laboratory

West Nile virus exists in nature through a transmission cycle involving mosquitoes and birds. Mosquitoes become infected with West Nile virus when they feed on infected birds, which may carry the virus in their blood for a few days. Infected mosquitoes can then transmit West Nile virus to humans and animals when biting to take a blood meal. In rare instances, West Nile virus may be transmitted from human to human through organ donation or blood transfusion or from pregnant mother to fetus. These new modes or transmission are still under investigation.

“Zika virus can pass back and forth between people and mosquitoes—most people get Zika from a mosquito bite, but infected people can also pass Zika to mosquitoes that bite them” (Schmidt, 2016).

First, the Zika virus is carried by mosquitos. It can be transmitted by getting bitten by an affected mosquito. For some people symptoms can be felt as brief mild flu-like illness (Brown). The virus has many ways of spreading throughout the world.

Her infection began when she was bitten by a mosquito which was seeking her protein-rich blood to nourish its eggs. As part of the process of sucking the droplet of blood from the girl, the mosquito, simultaneously injected saliva to ease the flow of blood into its proboscis. Malaria-causing pathogens gathered in the mosquito’s salivary glands and traveled into the girl’s body. Once in the body, the wormlike parasites moved to the girl’s liver to embed themselves allowing them to feed and multiply. By the time a week had passed, each parasite had consumed an entire liver cell and had replicated upwards of 40,000 times. A short time later the infected cells had exploded and the parasites had reentered her bloodstream. Now showing symptoms

Malaria is a disease of the blood that is transmitted from person to person by a female

Four stages of this parasite have been identified the first stage is the penetration phase which is day 1-17 during this stage the larvae moves into the body of the animal and moves to the lungs. The second stage which is the prepatent phase which is day 8-25
