Some of the most deadly diseases and devastating epidemics in human history have been caused by bacteria. Cholera Diphtheria Dysentery Plague Pneumonia Tuberculosis Typhoid Typhus VIRUSES A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to bacteria and archaea. The average virus is about one one-hundredth the size of the average bacterium. Most viruses are too small to be seen directly with an optical microscope.
Know the virus is very common from a single Mosquito bite during the summer season. However, not all mosquitos carry WNV. The Center for Disease Control and Prevention ( CDC) tell us that “West Nile Virus is an"arbovirus" that causes encephalitis (inflammation to the brain)” (CDC (2006). The virus can infect humans, birds, mosquitoes, horses and some other mammals. Buckley (2011)explains the process that occurs when a Blood-feeding insects such as mosquitoes become infected when they feed on infected birds, which leaves the virus in their blood for a few days ( para.2).
HSV Type II is the diagnosis of genital herpes. However, cross infection can occur between the two types from infected individuals participating in oral sex. Neonatal herpes is a very serious type of infection that has a 90% mortality rate among newborns. The Herpes Simplex Virus is a highly contagious disease that is spread by direct contact with lesions of an infected person. Herpes Simplex Virus is a virus that remains in latent state inside the ganglia, which is located near the spinal cord.
Smallpox is an incredibly deadly virus. It has a 20-60% fatality rate (80% in children). Small Pox has two variants, Variola Major, and Variola Minor. It comes from the Latin name Variola (once again that class helps me) meaning spots or pimple. Being a Virus, Smallpox cannot be cured, only vaccinated against.
USA vaccines cover A, C, W-135, and Y but not B (Coffee, 2015). The incubation period of meningococcal disease ranges from 2 to 10 days. The disease is spread through saliva and respiratory droplets. The most common way people transfer the disease is through kissing, sharing drinks, sharing used silverware, sharing lip balm, and close contact with an infected person who may cough or sneeze within three feet of an individual. Meningococcal meningitis is a fast moving, deadly infection that kills 10 to 13% of its victims within a matter of hours or days (CDC, 2015).
MEASLES SZT TASK 3 REBEKAH HIGHTOWER A. Measles Measles, what is it? Measles is one of the most highly contagious viral diseases and sadly it can be a fatal disease. This disease took the life of 164,000 children worldwide in 2008(Measles, 2014). It is caused by an infection called the rubeola virus.
The government were extremely concerned that this was going to be a repeat of the 1918 and 1957 pandemics; where nearly 50-100 million people died worldwide, but, the pandemics became milder as time went on. The deaths were reduced due to medical advancements and more people were aware of the actions needed to prevent the disease; so who is mot at risk? Anyone can suffer from swine flu, but children (specifically under 5’s because their immune systems aren’t fully developed yet), pregnant women and people with existing health problems; are the most affected. The puzzling aspect of the H1N1 virus is that it also effects the healthier of us. At one point, out of 77 deaths 1/5th were extremely healthy.

The disease spread to next door Denton County which reported 5 cases of outbreak. A4. Transmission Measles is a systemic viral infection caused by a paramyxovirus of the genus Morbillivirus. Its main features are fever, rash and respiratory disease (Hawker, Begg & Blair, 2012). Measles is also known as rubeola.
Although you can have a flu vaccination there is currently no vaccination for a cold. Common fungi infections include athletes foot and ring worm. These can treated with creams or tablets. These infections usually present themselves as dry, itchy red patches of skin. They are divided into two different groups: yeasts and dermotophytes.
