title: Congenital syphilis, a reemergent disease in Mexico: its epidemiology during the last 2 decades.
abstract: OBJECTIVE
  To describe the epidemiologic profile of congenital syphilis in Mexico between 1990 and 2009.
  
  
  METHODS
  The database of the General Direction of Epidemiology at the Ministry of Health in Mexico about congenital syphilis was reviewed. Data corresponding to the period between 1990 and 2009 were analyzed in every state of the Mexican republic.
  
  
  RESULTS
  A total of 1717 cases of congenital syphilis were reported during the study period. A 16.6% increase was observed between 2005 and 2009 and the quinquennium between 2000 and 2004. A trend toward increase in the incidence of congenital syphilis was observed with 2.9 new cases for each 100,000 babies born alive. The states that displayed significant positive trends were as follows: Baja California, Colima, Chihuahua, Jalisco, Nayarit, Sinaloa, and Zacatecas.
  
  
  CONCLUSIONS
  An increase in the number of cases of congenital syphilis is observed; the northern states are the ones that contribute the most to the statistics. There is a real need to refine the epidemiologic operations to detect and treat the cases of maternal and congenital syphilis in the country.
