Adesão vacinal para prevenção de infecções por papilomavírus humano na regional de saúde de Barra do Garças/MT

Abstract

The Human Papillomavirus, a sexually transmitted disease, is caused by the HPV virus, which are microorganisms capable of infecting the skin and mucous membranes, mainly through unprotected sexual contact. One of the main causes of infection by the HPV virus is cervical cancer, which is characterized by the appearance of warts in the genital area, being the third most lethal type of cancer in Brazil. Despite affecting mainly women in adulthood, there is an increase in infections caused by the HPV virus in adolescents due to the increasingly early onset of sexual activity. In Brazil, the quadrivalent HPV vaccine was instituted in the Unified Health System (SUS) in 2014, and is now available in all Primary Health Care vaccination rooms. In Brazil, the implementation of the anti-HPV vaccine by the Unified Health System (SUS) is extremely recent, initially making the quadrivalent vaccine that protects against HPV types 6, 11, 16 and 18 available to girls between 09 and 14 years old and boys between 11 and 14 years old; The National Immunization Program (PNI), a public policy under the responsibility of the Ministry of Health, is responsible for establishing the vaccination schedule and immunization strategies for the population. This is a cross-sectional, descriptive study, with the objective of analyzing the vaccination adherence rate for boys between 11 and 14 years old and girls between 9 and 14 years old, observing whether adherence to the vaccine system for HPV was influenced by the Covid-19 pandemic and whether there is a difference in vaccination coverage between males and females. A database created by the Epidemiological Surveillance of the Regional Health of Barra do Garças/MT, which covers 10 municipalities in the regional health of Barra do Garças-MT, was analyzed.
