Richard Reyes June 6,2015 Living Environment period : 6B-7 4th Quarter Project Throughout history humans have been at the top of the food chain , we have adapted to be able to live in a certain environment without dying. While everything seems fine , there are things that are lethal to humans and those things are diseases. While we have made some treatments to certain diseases such as the cold which is a minor disease but back in the past it was a huge disease.…
This disease is characterized by the sudden onset of a sustained and systemic fever, severe headache, nausea, and loss of appetite. Other symptoms include constipation or diarrhea, enlargement of the spleen, possible development of meningitis, and/or general malaise. When the bacterial cells enter, epithelial cells lining the intestine they cause host cell ruffling which temporarily damages the microvilli on the surface of the cell. This causes a rush of white blood cells into the mucosa, which throws off the ratios between absorption and secretion, and leads to diarrhea. Untreated typhoid fever cases result in mortality rates ranging from 12-30% while treated cases allow for 99%…
It cannot be passed on by breathing in the patient’s environment it can only transfer through physical contact. Furthermore, once the person has been infected they may suffer from several symptoms some of the symptoms that the patient will experience are a fever, headache, chills, upset stomach, itching, tingling, severe pain and vision loss.…
Introduction Norovirus infection causes inflammation in the stomach and intestines (gastroenteritis) and food poisoning. It is caused by exposure to a virus in a group of similar viruses called noroviruses. Norovirus spreads very easily from person to person (is very contagious). It often occurs in places where people are in close contact, such as schools, hospitals, and restaurants. You can get it from food, water, surfaces, or other people who have the virus (are contaminated).…
The rabies virus is a type of virus that would die out immediately in isolation. The virus has to have a host to survive and reproduce. The virus first “colonizes the salivary glands of its host, making it difficult to swallow” (Survival of the Sickest, paperback, p.104) Next, the virus makes its way into the host’s brain where it “chemically induces the animal to feel higher and higher levels of agitation and aggression” (Survival of the Sickest, paperback, p.104). With a mouth full of rabies-filled saliva, every bite is infectious.…
(3, 4) Targeted vaccination is key to controlling the outbreak and potentially preventing future similar scenarios. As discussed, adults and adolescents are common reservoir for infection. (1) Previous studies have found that household members, especially parents, are a primary source in approximately 76-83% of infant cases. (15) Cocooning is recommended in Australia and involves vaccinating household contacts with an infant less than 6 months. It will also be important to encourage families to undertake cocooning and the medical community in NSW to endorse this strategy and recommend it to parents.…
Facts about Norovirus The norovirus is highly contagious virus that causes irritation in the stomach and intestines; resulting in stomach cramps, vomiting, and diarrhea. The norovirus is so widespread that about one in 15 Americans will catch the norovirus every year, according to the Centers for Disease Control and Prevention (CDC). The norovirus is one of the viruses that can cause food poisoning; according to the CDC, leafy greens, shellfish (especially oysters), and fresh fruit are the most common foods associated with the norovirus.…
In “The Benefits of Vaccination Outweigh the Risks”, Noel Merino asserts the safety of vaccinations by listing the safety of four different vaccines in addition to the process of licensing and recommending vaccines in order for them to be safe for public use. Merino suggests that almost nothing is completely harmless by stating “But, in truth, few things meet the definition on ‘harmless’”, which is true because vaccines can cause side effects such as redness and irritation at the site of a vaccine injection. Diseases such as Hepatitis B and Rotavirus are very contagious among humans as it can be transmitted through face to face contact, so it is essential for people to take vaccines for these diseases so they will not likely contract these viruses from people who already have the virus. These vaccines are relatively safe because each vaccine must be thoroughly tested on countless subjects before it is submitted and then accepted by the FDA (Food and Drug Administration) for licensing. After the licensing, a vaccine is then recommended for public use and the administered by doctors so people can be safely immunized from contracting a [contagious] disease.…
This disease is most common in children and babies.…
Vaccinations are given to young children at an early age, which puts them at an increased risk of getting a disease. Children are receiving a multitude of vaccine doses, putting them at a higher risk of developing any type of disease. Many parents refuse to vaccinate their children, due to the fact that vaccines may cause side effects. Other parents choose to vaccinate their children to protect them from serious illnesses, including measles, whooping cough, and mumps. These are life threatening disease, and parents want to do everything that is possible to make sure their children are healthy and protected from preventable disease.…
Measles vaccination is the most effective way of preventing this disease. Though John Enders discovered the very first measles vaccination, using a killed virus wasn`t effective enough. In 1967, Maurice Hilleman advanced Enders` discovery by using a weakened live virus in the formula (“For Healthcare Professionals”, 2015). This attenuated vaccine is usually mixed with Mumps and Rubella to give protection against three kinds of viruses. Two doses of MMR are offered.…
Measles “Worldwide, about 20 million people each year get Measles” (For Parents: Vaccines for Your Children). This statistic shows that the measles infection affects many people worldwide each year. Measles is a highly contagious virus, that is most commonly found in children. Measles is a well known virus, that can have multiple symptoms associated with it. There is very little treatment options available that can be used.…
Human Papillomavirus Human Pappilomavirus, more commonly known as HPV, is a group of over one hundred and fifty viruses. It is the most common sexually transmitted infection. Almost all sexually active men and women will contract HPV at some point in their life. It infects the genitals of men and women, can cause warts and cancer. Cervical cancer is generally associated with HPV.…
