What is Dengue fever? Dengue fever (pronounced Den-gay) is a viral infection caused by the female mosquito (Aedes aegypti and Aedes albopictus). Dengue fever occurs in tropical and sub-tropical regions and usually increases in the hot and humid months. Dengue fever is not a new disease. It was discovered several hundred years ago. In recent years‚ dengue fever has become a major international public health concern. Dengue fever nicknamed "breakbone fever" because dengue patients usually express

remained one of the major public health problems in Nigeria. The obstacle to the success of malaria control and prevention interventions are both behavioral and non behavioral. The behavioral factors relate to cultural practices which promote mosquito breeding and mosquito access to people as well failure of the risk population to use technologies proven to be effective for the treatment‚ control and prevention of malaria promptly and appropriately. The main non-behavioral factors include geographical or

The Zika virus can be contracted by being bitten by the mosquito Aedes aegypti. Puerto Rico being an island where is warm all year round makes the perfect breeding environment for this mosquito. At least 117 people have tested positive for the Zika virus in Puerto Rico and five of them are pregnant women. The Zika virus in Puerto Rico‚ how did it get there? Is the population in Puerto Rico able to fight this epidemic? How can the people in the island protect themselves from acquiring this virus?

induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2 B is the magnetic field at the location of the coil. A is the cross sectional area of the coil‚ and Θ is the angle between the field and the area A. There is several different ways to create a changing flux though the coil. An easy way is to use

Bedeviled By Dengue Dengue is a mosquito-borne infection found in tropical and sub-tropical regions around the world. In recent years‚ transmission has increased predominantly in urban and semi-urban areas and has become a major international public health concern. Severe dengue (also known as Dengue Haemorrhagic Fever) was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand. Today‚ severe dengue affects most Asian and Latin American countries and has become a

somewhere along the miles of underground pipes‚ there is a blockage of some kind‚ and very little‚ if any‚ drain water can get by. This is a simplified comparison of what happens in the human body of a person living with lymphatic filariasis. A mosquito‚ after biting a person that currently has the disease‚ carries the larvae of the parasite that causes the symptoms and bites someone else‚ thereby passing on the larvae‚ or microfilariae‚ into the next host. Most people that are infected do not
