Herpes is an infectious disease that is causing more damage. The origin of this disease is attributed to a tiny virus that is part of a large family of herpes.NIs the chicken pox, shingles, genital herpes, cold sores.

One of the most common types of herpes is genital herpes, where the victim usually but not always contract the virus by having sex with another victim of shingles.

The symptoms are severe: between three to seven days after contracting herpes, the infected are burning your genital area after fluid-filled blisters appear which causes pain. This situation lasts two to six weeks and then heal. Read the rest of this entry »

The infection is the term for an infectious disease in general, or contamination by germs. It is the pathological consequence in a tissue or body of the abnormal presence and / or replication of a microbe bacterial, viral or fungal.

Contamination is the penetration of the germ in a body.

The infection is the branch of medicine for infectious diseases. The doctor is an infectious diseases specialist. Depending on the type of seed, also known as bacteriology, virology, parasitology. Sepsis is a serious infection. The term tank refers to a body or an object contaminated by a microbe (eg septic tank). Sepsis is a serious contamination and sustainable (without treatment) from the blood by a germ. Bacteremia is transient contamination of blood by a germ. When cases are increasing at a place and a limited time, we speak of an epidemic. If the distribution is much more widespread, it is called a pandemic.

When the epidemic on the animal community, we speak of an epidemic.

When the germ is transmitted from animals to man is spoken of anthropozoonosis or simply zoonosis. The contagion denotes contamination by germs. The incubation period is the period between contagion and the first manifestation of the disease. The patient may be contagious during this time. The contagious period is the time during which the patient excretes the germ and can transmit it. It depends on each infectious disease. Nosocomial infections are infections caught in hospital. They are particularly complex and dangerous because they occur in people weakened and often involve bacteria resistant to antibiotics. This is an issue of major public health.

An infectious disease is a disease caused by transmission of a micro-organism: viruses, bacteria, parasites, fungus, yeast. Viruses are not alive, but as a prion, which is not really a micro-organism they have properties like infectious, and therefore pathogenic effects.
The study of infectious agents is the medicine, microbiology, epidemiology and landscape epidemiology. In nature, infectious diseases develop in all living organisms (animals, plants, fungi, micro-organisms .. well known viruses virus). As Interaction lasting, infectious diseases are among the feedback loops that maintain the relative stability (dynamic equilibrium) ecosystems, most pathogens co-evolve with their hosts over millions of years. Their mode of transmission is variable and depends on their tanks (human, animal, environmental) and sometimes of vectors (disease vector).
They are more or less contagious; For example, tetanus is an infection caused by clostridium tetani, a bacterium that is found in the earth. There is no transmission, infection occurs when bacteria enters the body through a wound contaminated. A vaccine exists against this disease and is mandatory in France for all children of school age. Another example, malaria is caused by a parasite, Plasmodium falciparum (there are other Plasmodii), transmitted among humans through a mosquito, Anopheles. The reservoir of the parasite is human, but there is no transmission. There is no vaccine. Tuberculosis is spread from person to person by airborne mechanism: the reservoir is human and it is contagious. Sexually transmitted infections (STIs or STD for sexually transmitted diseases) are transmitted during sexual intercourse.
Many microbes live normally and necessarily in our gut and on our skin and become infectious at certain occasions. Contact with microbes is necessary for the maintenance and functioning of the immune system.
