In cerebral malaria, the infected red cells obstruct the blood vessels in the brain. Other vital organs can also be damaged often leading to the death of the patient. There are four species of Plasmodium that cause malaria, Plasmodium falciparum Plasmodium vivax Plasmodium ovale and Plasmodium malaria. While vivax is responsible for the largest number of malaria infections worldwide, infections by falciparum account for about 90% of deaths from malaria. Some places, such as Africa are so high at risk for the infection that someone of the population are starting to be born immune to the disease, precautions are still taken with things such as malaria nets of course.
A study reported in 1999 showed that without antiretroviral therapy, approximately 80% of HIV-infected children in Haiti were dead within 2 years of acquiring HIV infection. The responses to the HIV/AIDS epidemic in the Caribbean have varied over time and across countries. In the 2001 Nassau Declaration on Health, the Caribbean Community (CARICOM) declared the HIV/AIDS crisis to be a priority for the region. As part of their response, the Pan-Caribbean Partnership Against AIDS (PANCAP) was formed. This organization unites the Caribbean region and makes a difference in the lives of those with HIV/AIDS.
(Wikipedia contributors) The virus also remains alive and contagious on exposed surfaces and in the air for up two hours. Measles is highly contagious, over 95 percent of non-immunized children will develop the disease if exposed to the virus. (CDC) Symptoms of the disease first appear 10 to 12 days after initial exposure to the virus. These symptoms include cough, runny nose,fever, malaise, red watery eyes , koplik’s spots and the hallmark skin rash. (CDC) Initially a fever develops, followed by runny nose, cough and water eyes and koplik’s spots(small white spots that develop within the cheek and mouth).
Essay- Dengue fever What is dengue fever?Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes. It is an acute illness of sudden onset that usually follows a benign course with symptoms such as headache, fever, exhaustion, severe muscle and joint pain, swollen glands, and rash.According to the ministry, for the last five years, 8496 dengue cases were reported with 13 deaths recorded. Therefore, we must know the symptoms and signs of dengue fever and should be aware of this killer and take some safety precaution to avoid this fever. There are few symptoms and sign of dengue. After being bitten by a mosquito carrying the virus, the development period ranges from three to 15 days before the signs and symptoms of dengue appear.
Community Health and Population Focused Nursing C228 SZT Task 2 August 1, 2014 Measles p. 2 Measles, also known as Rubeola is a highly contagious acute viral illness. It is caused by a virus in the paramyxovirus family. In 1953, 549,000 measles cases were reported in the United Stated, along with 495 measles deaths, annually. Although 549,000 cases were reported, it is estimated that 3-4 million people or most every American was infected with this virus during their lifetime. After the implementation and licensure of the live measles vaccine in 1963 the number of cases significantly dropped by 1988 in the U.S...
Community Health & Population C228 Western Governors University VWT Task 2 The Ohio measles outbreak of April 2014 accounted for more than half of the reported cases that year. In Ohio Amish country of Knox county, three hundred eighty three people became ill after unvaccinated Amish missionaries traveled to the Philippines, only to return infected with the measles virus (Newsmax, 2015). It was on an April afternoon when the Knox County health department received a call from an Amish woman reporting that her family and her neighbor’s family both had measles. The health department immediately began to test the families by collecting samples, nasal swabs, and draw blood (Tribble, 2014). Once the measles virus had been confirmed it was reported to the CDC of the outbreak.
Most deaths occur among children living in Africa where a child dies every 45 seconds of malaria and the disease accounts for approximately 20% of all childhood deaths (WHO 2010). Malaria is a major cause of illness and death in Ghana, particularly among children and pregnant women in Ghana. In 2006, malaria accounted for 38.6% of all outpatient illnesses and 36.9% of all admissions (MOH, 2009). Malaria prevalence per thousand populations was 171 and 2,835 malaria-attributable deaths (all ages) representing 19% of all deaths were recorded. Infection rates are high in children peaking at more than 80% in those aged 5 – 9 years and falling to low levels in adults (MOH, 2009).
Dengue fever From Wikipedia, the free encyclopedia Jump to: navigation, search For other uses, see Dengue fever (disambiguation). Dengue fever Classification and external resources The typical rash seen in dengue fever ICD-10 A90. ICD-9 061 DiseasesDB 3564 MedlinePlus 001374 eMedicine med/528 MeSH C02.782.417.214 Dengue fever (UK: /ˈdɛŋɡeɪ/, US: /ˈdɛŋɡiː/), also known as breakbone fever, is an infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic morbilliform skin rash. In a small proportion of cases the disease develops to the life-threatening dengue hemorrhagic fever (bleeding, low levels of blood platelets and blood plasma leakage) and dengue shock syndrome (circulatory failure).
Polio is a crippling and potentially deadly infectious disease caused by a virus that spreads from person to person invading the brain and spinal cord and causing paralysis. Because polio has no cure, vaccination is the best way to protect yourself and the only way to stop the disease from spreading. The spread of polio has never stopped in Afghanistan, Nigeria and Pakistan. Polio-virus has been reintroduced and continues to spread in Chad and Horn of Africa after the spread of the virus was previously stopped. In the late 1940s to the early 1950s, in the United States alone, polio crippled around 35,000 people each year making it one of the most feared diseases of the twentieth century.
Chapter I: Introduction BACKGROUND OF THE STUDY One of the most prevalent disease carriers today is the mosquitoes. The female mosquito needs to obtain protein nutrients from a “blood meal” before she can develop and produce larvae. There are about 3,500 species of mosquitoes found throughout the world and most are vectors for a number of infectious diseases affecting millions of people per year. According to the World Health Organization, global warming enhanced by deforestation and environmental degradation causes the alarming increase in the range of mosquitoes carrying malaria, dengue fever and yellow fever, putting millions more humans at risk. One effective way of controlling mosquito bites is the use of insect repellant to ward off female mosquito bite.
