Background: According to the data of the 2012 HIV epidemiological bulletin, since 1980 to 2010, occurred 241,662 deaths caused by HIV in Brazil. We found no studies about the seasonal demand or diagnostic tests for HIV’s infection in Niterói population, which are very important to the public health policies organization in Brazil. On the other hand, Brazilian Healthy Ministery makes a great campaign at Carnival time, as part of the popular imaginary that there is a global promiscuity in carnival.
Methods: It is a transversal analytical study time series. It has been analyzed data demand of positivity anti-HIV tests and the days worked by CLPHMV, collected from a database relative to the period of 2005 to 2010, represent a sample space 64.505 exams. Hereafter, were been statistically analyzed by a temporal serie and hypothesis tests for trend and sazonality, the classic series decomposition, by Morettin/Toloi.
Results: demand of anti-HIV exams: 2005 (11.252); 2006 (10.557); 2007 (11.494); 2008 (11.046); 2009 (10.452) and 2010 (9.704). Positivity: 2005 (42,6); 2006 (44,0); 2007 (38,3); 2008 (32,8); 2009 (24,25) and 2010 (25,25).Annual work days2005 (218); 2006 (235); 2007 (238); 2008 (236); 2009 (237) and 2010 (211).
Conclusions: There wasn’t a seasonal relationship between the demand and the positivity of anti-HIV tests, performed in CLPHMV. There was a decrease, statistically important, on demand and positivity of the anti-HIV tests, over the years studied between. We found no list of increasing demand and neither positive that may be related to the carnival.
