Malaria
What is malaria?
Malaria is a potentially fatal disease. Especially in countries with tropical climates and developing countries. Malaria plays an important role in the health of the population. Is an infection of red blood cells by a parasite that destroys them.
What causes malaria?
Malaria is caused by infection with the microscopic parasite plasmodium. There are over 150 species of Plasmodium that infect different vertebrates, but only four (P. falciparum, P. vivax, P. ovale and P. malariae) infect humans. The two most common species are P. causing acute falciparum malaria and may lead to death and P. vivax which causes infections and recurrent debilitating but rarely fatal.
The plasmodium is transmitted to humans through bites from Anopheles mosquitoes infected with the parasite.
In humans, the parasites migrate to the liver where they mature and then enter the bloodstream and infect red blood cells.
The parasites multiply within red corpuscles, after 48 to 72 hours, break and infect more red blood cells.
If a mosquito carrying the parasite is not piqa an infected person can infect others. Read the rest of this entry »
Health Definitions
There are several concepts for the definition of health, the first that addresses health is a concept that refers to an unstable equilibrium of the human being, its biological organism and its body (understood as representations of the same), in conjunction with biological, environmental, cultural and symbolic, allowing each addition to growing human being, enhance their potential in terms of their own interests and those of society in which it is immersed.
When any of these items are changed every other altered for a new balance of human beings. Such change may be transient, and process restarts intermittently before or fleeting casualty occurred in any of the above factors. The responses selected by the human face of these external or internal stimuli are many and varied according to their skills.
Health is therefore more than a state, an ongoing process of restoration of balance, a process that when some of the factors involved change and that change is maintained over time, the human being takes a fixed answer, which was sometime prior adequate to restore balance, but at the turn, leads to an inflexible catastrophic state that may be incompatible with life (Canguilheim 1982). This view implies that to maintain this balance requires a range of socioeconomic, environmental, biological, and health care that are brought together to sustain this equilibrium, which translates into the ability to live as an individual, to produce, reproduce and recreate the culture, understood as the sum of production, and institutions that human life away from the animal.
