The vector borne diseases that I will be comparing to schistosomiasis are Chagas and Japanese Encephalitis. Even though these diseases are all vector borne it does not mean that there are not their individual differences. Amongst all three of these diseases the aspects that can be compared are transmission and vector, people most at risk and symptoms produced by each.
The main thing in common with these three diseases is also the main difference right off the back besides their names. For schistosomiasis, its vector is the fresh water snails (Bulinus, Oncomelania, Biomphalaris), for Chagas the vector is the triatomine bug or kissing bug and lastly Japanese Encephalitis vector is the Culex tritaeniorhynchus mosquito. When it comes to schistosomiasis the way the disease is transmitted is by the free-swimming parasite entering your body through broken skin or urethra or rectum. So, unlike Chagas or Japanese Encephalitis the

For schistosomiasis, the places most at risk for infection are countries in Africa and some water bordering countries of south America. And even then, people are only at risk is they drink or swim in the fresh water lakes and rivers present in the area, especially if they live in tropical regions and sub-tropic regions where people live close to rivers or oceans. Outbreak has not been as bad in recent years because the fresh water bodies where the fresh water snails are present are being ignored. Another one the diseases that is present in south America is Chagas. However, its presence is more prevalent and spreading to central America, Mexico and north America and non-known presence in the continent of Africa but some in Europe and Australia. Now the area in where J. Encephalitis affects should not be that hard to figure out since the strain Is mostly found in Asian countries and surrounding islands but predominantly found in

Although mad-cow disease is always fatal, it is not really much of a worry in the United States. There have only been four cases of mad-cow disease ever recorded in the United States. In every case, the United States Department of Agriculture has intervened and recalled tons of beef, 10,400 lbs. in the first case to be exact, in order to insure that the meat did not reach the plates of United States citizens.
The human immune system is an amazing system that is constantly on the alert protecting us from
An animal infected with CWD will have neural loss, astrogliosis, which is an abnormal increase in the number of astrocytes in the brain, and spongiform lesions (Abrams et al., 2011). The infected particles are spread all throughout the body including the brain, spinal cord, eyes, peripheral nerves, and lymphoreticular tissues (Belay et al., 2004). Most of the infection, however, is located in the Central Nervous System.
The Measles starts with a fever, runny nose, cough, red eyes, and sore throat. It is then followed by a rash that spreads over the body, starting first on the face along the hairline. The infectious period of measles is 4 days before rash onset through 4 days after rash onset. The measles are a highly contagious virus that lives in the nose and throat mucus and spreads through the air through coughing and sneezing. (WHO, 2016). The measles virus can remain airborne for up to an hour after the infected person has left the area. The measles are so contagious that if one person has it, 90% of the unvaccinated people close to them will become infected. Rarely can the virus be deadly. The incubation period for
You wouldn’t think the carrier of this disease would come from a little mosquito bite, but it does. 1. What is the difference between a. and a. According to the U.S. Food and Drug Administration, on their website Animal and Veterinary it states the following. Show a slide of how the heartworms are transferred.
While many forms of encephalitis exist, West Nile Virus was first isolated and identified in the West Nile District of Uganda in 1937. The virus, which was seemingly isolated to North Eastern Africa, became recognized as a cause of severe human meningoencephalitis (inflammation of the spinal cord and brain) in elderly patients during an outbreak in Israel in 1957. In addition to the human victims of this disease, the virus was found Egypt and France during 1960s to have fatal effects within horses. While this disease spread through Northern African and Southern Europe, 1999 marked the first appearance of West Nile Virus in North America, with encephalitis reported in both humans and horses.
A disease is transmitted in one way or the other. Lyme disease is transmitted through a vector. The vector of the disease is an infected deer tick. The deer tick has to bite a person to spread the disease. When a deer tick bites a person (sucks blood), the Borrelia burgdoferi bacteria is transmitted into the persons body.
The infection transferred easily as breathing the air of an infected victim in some cases. The disease came in three different forms such as, Bubonic, Sympathetic, Pneumonic but all resulted from the same thing. Although the disease was rarely spread from human to human people were still frightened because it could spread from clothing to a cut in the skin. It also was contagious if you had close contact with a rat or had got bite by a flea.

According to Aberth, "disease is a constant force in human history that has had much more than just demographic repercussions"(Aberth 2007, Pg.X). It has created fear, awareness, pain and frustration for the lack of knowledge of it cause. In 1500 through the 20th century, the primary reasons for disease to spread so effectively are animals, trade routes and colonization/ imperialism. The disease was widely spread through warm climate and the geographic of the world because the virus host bacteria was able to grow and attack the human body.
In1994, there is another outbreak in Motaba River Valley. Unfortunately, an African monkey carrying that biological agent (pathogen must exist in order for the disease to occur) has brought into the United States. Unfortunately, the film shows two outbreaks that occurred in Boston and California. Outbreak portrays communicable (infectious) disease in the Cedar Creek. Communicable diseases are diseases that can be transmitted from one person to another through biological agents or their products. This biological agent had all three characteristics: infectivity (Ability to invade a host, survive & multiply) , pathogenicity (experience to produce clinical disease) and virulence (ability to cause serious illness...
Infectious diseases also called as communicable diseases are caused by pathogenic microorganisms (such as bacteria, viruses, parasites or fungi), can be spread directly or indirectly from one person to another.

There are hundreds and thousands of communicable diseases that affect children in life each and every day. Some disease are deadly and some are not. Some of them have been slowed down or controlled by vaccines and modern technology. Although some are being controlled others resist drug treatments. Theses are the types of diseases that become difficult to cure and can kill a child. It is difficult to prevent children from catching the spread of communicable diseases because of how easily some are able to spread, because it is just part of our everyday life and because children are always around objects and things that are highly contagious. For example in daycare or schools, they have toys and crayons and other objects that are always being touched by other children. In playgrounds there are pathogens everywhere. Pathogens is another term for germs. A communicable disease is a disease that is transmitted by the contact of person to person or animal to person. Communicable disease are spread by contact with an infected person or object ,oral transmission, pathogens in the air, when many people with a communicable disease are among the same area, bites from insects and not in the case of children, sexual intercourse. Pathogens that can cause communicable diseases are viruses, bacteria, fungi, Protozoa, multicellular parasites, and aberrant proteins. Bacteria is a one- celled germs that multiply quickly and may release chemicals which can make you sick. A virus is capsules that contain genetic material, and use your own cells to multiply. A fungi is a primitive plants, like mushrooms or milde. A protozoa is a one-celled animals that use other living things for food and a place to live. When a child becomes sick with a communicable dis...
