Disadvantages Of Parasites

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.

Very severe outbreaks may have symptoms that include swollen and tender lymph glands in the groin, throat, or under the arms, and even flu-like feelings such as fever, chills, headache, and a general run down feeling.

Parasites are plants or animals that derive benefit from the metabolism of other plants or animals at the expense of the host and without providing some benefit to the host in return.

As the disease progresses the pulse slows and weakens, bleeding of the gums, and bloody urine occur. In more severe, usually fatal cases, jaundice occurs, which is what the disease is named for. Jaundice is when the patient's skin turns yellow and is the final definitive test to detect yellow fever, although by that stage it is usually too late. In the rare cases where people recover from the disease, the person develops an immunity to the disease.

It is very important to immunise against this disease not only because it is a very contagious virus but because it can have some very serious long term effects.

Not only are humans threatened by viral and bacterial infections, there are various parasites that also invade the human body. Parasitic infections are common in underdeveloped countries and are a prominent threat in rural areas. Though parasitic infections are known to happen in well-developed countries such as the United States. Contaminated water supplies, contact with infected animals, and improperly stored and cooked food can lead to parasitic infections. Parasites like tapeworms, protozoa, flukes, and nematodes can infect humans, causing serious health issues. These parasites enter through various parts of the body, and then live and reproduce in certain organs. Though there are many points of entry into the human body, most parasites enter

The symptoms of yellow fever are varied. The virus has an incubation period of three to six days. The first symptoms will be fever, muscle pain, backache, headache, shivers, and loss of appetite, nausea, and vomiting. Frequently a slow pulse accompanies the fever. Most people improve after three to four days, however in 15% of the cases; patients go into a toxic phase within 24 hours. Fever reappears, and they exhibit jaundice and abdominal pain with vomiting. Bleeding occurs from the mouth, eyes, nose and stomach. The kidneys fail to produce urine, and blood appears in the vomit and feces. Half of the patients who experience this toxic phase die in ten to fourteen days. Due to the fact that many of these symptoms are identical to malaria and other diseases native to the areas, yellow fever is difficult to recognize. Blood tests can identify the virus, but may not be easily available to people in poorer developing countries.
