Free radicals are one cause of dangerous diseases such as cancer, and in the field of beauty can lead to premature aging. There’s a lot of disease that we get from mosquito an example disease here is dengue. Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.
However, one common viral infection causes the viral fever, which is a viral infection in the upper respiratory tract. Acute viral rhinopharyngitis is the most common cold known and the most familiar infectious disease as well. Well, it's worth telling you that viral fever has no further medical complications despite how weak and fatigue it makes you feel. you'll be surprised to know that over 200 different viruses can cause colds. However, you should know the 4 common viral infections which are seasonal influenza (the flu), sinus infections, sinus infections & viral gastroenteritis.
Staphylococcus Aureus belongs to the extremely common bacteria of microflora of the skin and mucous membranes of the humans. These pathogens cause many infections, including superficial and deep purulent infections, poisoning, urinary tract infection etc. In the US, staphylococcus bacteria are supposed to be the leading cause of sepsis, postoperative wound and prosthesis infections. In addition, staphylococcus belongs to one of the leading causes of bacterial food poisoning. Staphylococcus Aureus is one of the most dangerous human pathogen.
Malaria is a contagious disease caused by five different Plasmodium parasites that have similar life cycles.1 These parasites have a complex life cycle that requires an insect vector most commonly female Anopheles mosquito and a human host. The life cycle of the malaria parasite is composed of human stages and mosquito stages.2 The discovery of the first stage during which the parasites develop in the liver before entering the blood stream was done by Henry Shortt and Cyril Garnham in 1948. In 1982, another discovery was made by Wojciech Krotoski demonstrating the presence of dormant period in the liver that occurs in the final stage. These discoveries play an important role in the understanding of the life cycle of malaria prasites.1 Moreover,
The major problem in Malaysia is the outbreak of dengue cases is which firstly recorded occurred in Penang on 1901 until 1902. DEN-1, DEN-2, DEN-3 and DEN-4 are four serotypes of dengue virus which are of genus Flavivirus (Anonymous, nd) Ae. albopictus and Ae. aegypti is mosquito vector that can spread virus to human by transovarial spread from infected female’s mosquito to its progeny by contagion of ovaries and eggs. Thus, mosquitoes born comprise identical viruses as adult mosquito or as their mother (Anupong Sujariyakul et al., 2005).
At regular intervals of 48-72 hours, the parasite blasts in the red blood cells and new parasites are released. Malaria is not commonly spread directly among people but it can be spread when a mosquito bites an infected person and later bites an uninfected person and on rare cases, it is spread through blood transfusions. Symptoms of malaria may be similar to those of a common flue or cold, which are pain, fever, headaches, profuse sweating and others depending on the strength of the immune systems of the
Mosquitos breed in water, and when they bite a person infected with malaria, they can spread the infection to other people. Symptoms of malaria include fever, headache and shivering. In severe cases, it can even lead to complications like pneumonia, severe anemia, coma and death. To prevent breeding of mosquitos and malaria, pooled water must be eliminated. You can also use mosquito nets and pesticides and practice good sanitation.
Rotaviruses are characteristically identified as particles encapsulated in a double-shell, and measuring approximately 70 nm in diameter. Different strains of parvovirus have also been found to cause diarrhoea in epidemics in many different parts of the world.2 Pathology After finding its way into the body, the rotavirus typically infects the intestine's epithelial cells, resulting in atrophy and death of the intestinal villi. Although both the rotaviruses as well as the parvovirus can cause gastroenteritis, they differ in the sense that the parvovirus is not found in the epithelial cells of patients.2 Symptoms Patients with viral gastroenteritis typically develop symptoms between 24 - 48 hours after the initial infection. Gastroenteritis involves the inflammation of the small intestine, its symptoms are somewhat similar to appendicitis the two may at times be confused with one another.3 However, pain caused by gastroenteritis is more generalized. According to the web article Viral Gastroenteritis (Pietrangelo A.
The most common symptoms of flu are fever, sore throat, muscle pains, head-aches, cough, and fatigue. It is like a common cold, but it is more severe disease. It may also cause vomiting, particularly in children and it is more common in them, which is sometimes referred to as stomach flu. Typically, it is transmitted through the air by cough or sneezes, containing some aerosols that is containing the virus. It affects the immune system by a virus that enters our body.
Identifying environmental risk factors for endemic cholera: a raster GIS approach NAME:P.J.D.V SAINADH ID:-ST117032 Abstract:- In this study we identify the environment risk factors that cause cholera in Bangladesh using GIS. Two study periods were chosen because they had different dominant biotypes of the disease. From 1992 to 1996 El Tor cholera was dominant and from 1983 to 1987 classical Cholera was dominant. This study founds the three risk factors for cholera related to surface water, high population density and poor education level. The GIS database helps us to measure
