Generally speaking, contagious diseases are manifested by the transmission of one affected person to another previously considered healthy. Some diseases seem more contagious than others. What are these diseases? This article introduces you to some of them.
Influenza appears to be one of the viral and contagious diseases. This disease is caused by a virus called influenzavirus (virus existing in several forms). It has its own season of contamination that is the winter. In fact, being transmissible by direct contact or by touching infected materials, this disease resists for a long time outside the body. Thus, recommendations are made during the winter to cure this disease. It is a question of washing the hands frequently, of protecting the mouth well before sneezing and of airing regularly its residence.
As everyone knows, chickenpox is very contagious. It is caused by the varicella zoster virus (vzv) which has two routes of transmission. These include: direct skin-to-skin transmission and airborne transmission (sneezing, coughing). Generally, the contamination of this disease takes place 48 hours before the first spots are discovered on the body parts. There is no fixed age for catching chickenpox. However, it appears already at the age of 10 years for most cases.
Still called "kissing disease", mononucleosis is a disease caused by the Epstein-Barr virus. It is transmitted only through contact with saliva. It should be noted that most children are infected at an early age. At this stage of contamination, the disease remains unidentifiable. This is the reason for the risk of spreading the disease during adolescence.
The Human Immunodeficiency Virus (HIV) appears to be one of the most contagious diseases that is transmitted sexually. This sexual transmission manifests itself in several forms such as: transmission from mother to child, unprotected sexual intercourse including anal, oral or vaginal penetration. It progressively destroys the cells programmed to ensure the body's immunity.
