Facts about infections.

                                                                        Infection                                                                          This refers to the invasion of an organism’s tissues by organisms that are disease-causing. These organisms upon multiplication and increase of their numbers usually create toxins which eventually create infectious diseases.                                                                                                                                       Evidences of infections are medical signs and symptoms of a certain disease, growth and presence of pathogenic agents when the host’s tissues and cells are tested clinically.                                                    The causative agents of infections include viroids, viruses, microorganisms such as bacteria, arthropods such as tick and lice, fungi e.g. ringworm's, prions and macro-parasites e.g. tapeworms.           

Hosts usually have the ability to fight such infection through the use of their immune system and an example of this is the mammals, whereby, they have an innate system that reacts to infections which yield inflammation and eventually an adaptive response is given by the immune system.                                                                                                                                               Application of various recommended pharmaceuticals is also useful in combating a variety of infections.                                                                                                                                                  

The elements used in classification of infections include the following:

·         The causative agent.

·         The symptoms.

·         The medical signs achieved.

An inactive infection-type is usually known as a latent infection.                                                                           

There are two broad divisions of pathogens which include:

·         Opportunistic pathogens which is characterized by causing an infectious disease with depressed resistance to a host. They are usually caused by microbes that are in contact with the host such as fungi and may also be caused by microbes that have been acquired by the host form other hosts. In order to curb this infection, a series of practices such as impairment of defenses of the host.

·         Primary pathogens which have the ability to cause a variety of ailments due to the presence of those pathogens and the activity they undertake with a healthy, normal host. Most primary pathogens that are found in humans have the ability to infect humans although severe illnesses are caused by those organisms that have been acquired from the environment or certainly those that have been profoundly known to infect other hosts that are not human.

An infection can be categorized by the organ system that is infected and some of the common infections include:

·         Skin infection.

·         Intra-amniotic infection.

·         Urinary bladder infection.

·         Respiratory tract infection.

·         Vaginal infections.

·         Odontogenic infection.

Signs and symptoms

Symptoms are usually dependent to the disease type and some may include the following:

·         Loss of appetite.

·         Loss of weight.

·         Severe fatigue.

·         Chronic fevers.

·         Night chills and sweats.

·         Back aches and acute pains.

·         Nausea.

·         Lack of sleep i.e. insomnia
