Primary Outcome Measures:
  • Anti-HAV seropositivity status: Subjects with anti-HAV antibody titers >= assay cut-off. [ Time Frame: 6 to 10 months from study initiation ] [ Designated as safety issue: No ]
  • Anti-Pertussis Toxin seropositivity status for IgG and IgA: Subjects with anti-Pertussis Toxin antibody titers >= assay cut-off for IgG, Subjects with anti-Pertussis Toxin antibody titers >= assay cut-off for IgA [ Time Frame: 6 to 10 months from study initiation ] [ Designated as safety issue: No ]
  • Anti-VZV seropositivity status: Subjects with anti-VZV antibody titers >= assay cut-off [ Time Frame: 6 to 10 months from study initiation ] [ Designated as safety issue: No ]
  • Anti-CMV seropositivity status: Subjects with anti-CMV antibody titers >= assay cut-off [ Time Frame: 6 to 10 months from study initiation ] [ Designated as safety issue: No ]
  • Anti-HSV seropositivity status (defined as the percentage of subjects with anti-HSV 1 and 2 titers >= assay cut-off): Subjects with anti-HSV antibody titers >= assay cut-off [ Time Frame: 6 to 10 months from study initiation ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Difference in HAV, VZV, CMV , HSV and BP seropositivity rates according to socioeconomic status, age group, gender, region, risk group, area and pertussis vaccination status (only for BP analysis) [ Time Frame: 6 to 10 months from study initiation ] [ Designated as safety issue: No ]

Detailed Description:

In order to document the epidemiological changes in the sero-prevalence of Hepatitis A, Human simplex virus (1 and 2), Varicella-Zoster virus and Cytomegalovirus infections, we propose to conduct a population based, seroprevalence, cross-sectional study, in Mexico. This will allow the identification of susceptible populations, which in turn, will serve as evidence for the elaboration of recommendations for the prevention of Hepatitis A, Human simplex virus, Varicella-Zoster virus and Cytomegalovirus infection in the region.

This study was conducted using data and serum samples from a random sample of subjects that participated in the 2006 National Health and Nutrition Survey.

  Eligibility

Ages Eligible for Study:   1 Year to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population

The study population will include a random sample of 4000 subjects of subjects who participated in the 2006 National Health and Nutrition Survey (ENSANUT).

Criteria

Inclusion Criteria:

• Previously enrolled subjects aged >= 1 to 70 years for National Health and Nutrition Survey 2006 in Mexico, with previously obtained informed consent

Exclusion Criteria:

  • Information required for the study is not available or incomplete.
  • Inadequate or insufficient serum sample to detect viral agents required for the study.
  • Serum sample wrongly identified.
