The Latin word incubator He arrived in Spanish as incubation . He concept is used to refer to act and the result of hatching .
East verb (hatching) has three great uses. You can refer to the action of heating the eggs carried out by oviparous animals so that their young develop and be born; to progression from when a disease is contracted until its first symptoms are evident ; or to the first steps of a social movement, a trend or a venture before it is fully manifested.
The idea of incubation, therefore, can be used to name the task undertaken by the birds and other oviparous species so that eggs They put keep warm and, in this way, the embryos grow until the right time of hatching.
Usually, incubation consists of transmit body heat from the parent to the egg. For this the animal It is located on the developing breeding. Some species, on the other hand, appeal to the sun's rays, geological heat or even the energy generated by rotting plants.
Incubation can be developed by the female , by the male or in a shared way. The most common is that the female is responsible for the entire process.
In the field of medicine , on the other hand, is called incubation period at the time that elapses from exposure to radiation, a chemist or an organism of a pathogenic nature until the manifestation of the first symptoms and signs of the disease. Thus, it can be said that incubation begins when an infection occurs and reaches the clinical onset of the disorder.
It is important to note that the duration The incubation period is variable, since it depends on the stimulus that affects the individual: while in some cases it can last several years, it is also possible that it does not exceed a few minutes. Let's look at some cases in particular to graph this difference in the time that elapses from exposure to the pathogen until the onset of the first symptoms:
* cellulite, which occurs because of the action of the microorganism known as Pasteurella Multocida, has an incubation period of less than one day;
* among the diseases that take at least a day to show the first sign We can mention cholera, influenza, scarlet fever and Ebola. We must emphasize, however, that while the first three do not exceed four days of incubation, in the case of Ebola we have a maximum that ranges between twenty-one and forty-two days;
* the common cold and spotted fever of the rocky mountains, on the other hand, have an incubation period that can be as short as two days;
* the minimum number of days that can pass before the first ones appear symptom in the case of polio, whooping cough, smallpox and generalized tetanus is seven;
* the minimum incubation period for roseola is five days, and then we go to the nine days that measles takes to enter the thirteen of the erythema infectious ;
* chickenpox, mumps and rubella increase the number of days to fourteen, while infectious mononucleosis amounts to twenty-eight;
* away from a few days, the disease neurodegenerative and infectious known as kuru It has a minimum incubation period of more than ten years.
These numbers are based on statistical studies, and therefore are always subject to changes that emerge from the contrast with new data. In general, adults have longer incubation periods than children.
