Measles Research Paper

Rabies is known as a very deadly virus spread to people from the saliva of infected animals. The rabies virus is usually transmitted through a bite. In the late 1800 rabies was well known to cause different symptoms, including itching, fever, headache, excess salivation, muscle spasms, and mental confusion. These symptoms tend to spread through entire body. Recently

Centers for Disease Control and Prevention. 2 July. 2015. Web. 27 Aug. 2015. Rabies is a viral disease that is only carried by mammals.

Infectious diseases are caused by the intrusion of a host organism by foreign organisms, which are generally named microorganisms but are often called microbes. These microbes can also be known as pathogens if they cause an illness. The most common pathogens are bacteria and viruses, although a number of microbes also cause disease. When an organism is linked to an infecting microbe, it is known as the host for that microbe.

The plague, also known as the black death, is a serious bacterial infection that can drastically end people's lives. The disease is caused by a bacterial strain called Yerisinia Pestis, which is found on animals around the world and transmitted to humans through fleas. In Europe, millions of people were killed during the middle ages ( about one quarter of the population ) due to disastrous epidemics of plague. The plague has three basic forms: Bubonic plague, Septicemic plague and Pneumonic plague. After 2 to 6 days of infection people whom are diagnosed with plague will usually develop flu-like symptoms followed by other signs according to the type of the plague they are suffering from.

Endemic Typhus, was one of the most common diseases spread in concentration camps; killing many, including Anne Frank and her sister, Margot. Usually taking place in areas with poor hygiene and cold temperatures, it is also referred to as "jail fever. " The bacteria that causes this disease is spread from rats to fleas to humans.

We are writing to inform you about a possible spread of Herpes simplex. We are reaching out the parents due to a few students outbreaks. Herpes simplex can attack both children and parents so if signs are present be careful as it is very contagious. Herpes complex is known as Herpes liabalis, otherwise known as fever blisters or cold sores. Signs of this illness are visible vesicles either in the lips or adjacent skin.

– During the early stages of Lyme disease, many people develop a red, circular skin rash known as erythema migrans. The rash, which may be diffuse and hard to discern, may not always appear at the bite site, but elsewhere and can develop up to thirty days after being bitten. However, about one in three people infected with Lyme disease do not see a rash. Some people also have flu-like symptoms in the early stages, such as a high temperature, or feeling hot and shivery, headaches, muscle and joint pain, tiredness and loss of energy. Not all tick bites cause Lyme disease.

Shingles What are shingles you might ask? Shingle are a reactivation of the chickenpox virus in the body, causing a painful rash. Herpes zoster is another name for the virus. Shingles was thought to be a fairly painless and harmless virus until the 1950s, when the medical community first recognized the severity of the symptoms of shingles.

Because it has so many different symptoms, it is extremely difficult for doctors to recognize. When a patient first gets a tick bite, they usually contract a bull’s eye rash which “starts as a small red spot that expands over a period of days or weeks, forming a circular, triangular, or oval-shaped rash” (“Lyme Disease Overview”). However, this rash, scientifically called erythema migrans, only appears in seventy to eighty percent of Lyme disease victims, making the disease even harder to diagnose. Early symptoms of Lyme disease include flu-like symptoms such as fevers and chills, joint pain, and muscle aches. After a couple months, victims of Lyme disease may develop many symptoms such as facial paralysis, poor memory, weak limbs, heart problems, and swollen joints.

“How does it spread?” one might ask, Rotavirus is spread stool to mouth, by touching a contaminated surface, this virus can also live on hands, toys, changing tables, and more. Many children get Rotavirus from being around other children, in daycares or preschools. Due to this, children tend to take the virus home, potentially spreading it to others within the

Sickle cell disease is a random illness that affects a person 's blood system and currently is incurable; however, it can be diagnosed and treated and scientists are hopeful that one day they will find a cure. Furthermore, sickle cell has a long history as a disease that

With advancement in the field of genomic sequencing, investigation allows for cognition of the basis of host adaptation and the extent of the natural reservoir of influenza viruses. The key to predicting future viral pandemics is the required depth of historical, epidemiological, and biological knowledge surrounding the 1918 flu pandemic. For a number of years, the prediction of a new influenza pandemic of large-scale proportions, namely the Avian flu, has become a global concern. With extreme population mobility it is more important than ever for global pandemic preparedness to be emphasized.

This means that contracting the disease is very easy, and depends on the status of the receivers immune system, as well as proximity and frequency of exposure to the diseased

Viruses, unlike bacteria, are not cells; they are parasitic invaders and consist of a fragment of genetic material, either DNA or RNA, inside a protective protein coating. (Science dimensions 4) Viruses can only reproduce inside host cells. Once inside, they take over the control of the cell and program it to make even more virus particles. When the number of virus particles reaches its maximum, the cell breaks apart, releasing the virus and allowing it to attack other cells. Sometimes Viruses can remain inactive for long periods of time following the invasion of cells.

It is usually, but not always, spread by a scratch or a byte by infected animals. After entering animal body, Rabies virus travels along muscle and nervous system and destroy the receptors on nerve cell membrane. Eventually the central nervous system of the infected animals will be destroyed and the infected animal will
