Herpes: caused by Herpes simplex, contagion occurs through direct or indirect contact with wounds from infected individuals. It can manifest in the mouth (herpes type 1) or genital region (type 2), with the presence of blisters that later become sores and give the patient a burning sensation in the affected region. Such lesions heal within a few days, but the virus remains in the body, and usually manifests itself when the individual's immune system is weakened.
Mononucleosis: mainly affecting teenagers, this disease is caused by the Epstein-Barr virus, whose infection can if it is asymptomatic or gives the individual fever, sore throat and water, especially in the neck. In rare cases, there may be nervous and cardiac system involvement, being fatal in approximately 1% of cases. It is transmitted by exchanging saliva with an infected individual and, therefore, it is also known as “kissing disease”. There is no vaccine or treatment for this disease, whose virus remains latent in the body.
Polio: caused by the Enterovirus, it can only cause headache, fever and malaise, regressing naturally; or, in some cases, the pathogen enters the bloodstream and attacks the nervous system. There, it infects motor cells, causing muscle atrophy and paralysis in the individual. For prevention, it is necessary to sanitize food well before consuming and avoid direct or indirect contact with the saliva of affected individuals. Also, the use of the vaccine is very important.
