[Prevalence of complement fixation antibodies of cytomegalovirus in various Mexican communities]
Abstract:
In 1962 Weller and Hanshaw reported evidence of the teratogenic potential of CMV (cytomegalic inclusion disease virus or cytomegalovirus) for the developing human embryo. Some other investigators have also shown that CMV may be involved in different pathological conditions, that it is an ubiquous agent capable of producing a high incidence of infection, usually asymptomatic, under quite diverse ecological conditions, and that the proportion of individuals that have been in contact with the virus increases with age, which is evidenced by the frequency of seropositivity to the specific antigen. The high prevalence of CF antibodies to CMV in the studied groups from the state of Chiapas, particularly in Lacanjá where 45% of the total population (120 inhabitants) was included in the survey, indicates a wide dissemination of this virus. Lower levels of seropositivity were found among children from the Mexico City group, but they are higher than those found in serological surveys in children from Huixquilucan (state of Mexico) and from Seattle and Dallas in U.S.A. The possible implications of some seroepidemiological characteristics of CMV infection are discussed.
Insights
Cytomegalovirus (CMV) infection is widespread, particularly in Chiapas, Mexico, with high seropositivity rates in adults. This study examines CMV prevalence across different Mexican populations and compares it to US data.
Area of Science:
- Virology
- Epidemiology
- Public Health
Context:
- Cytomegalovirus (CMV) is a ubiquitous virus with known teratogenic potential.
- CMV infections are often asymptomatic but increase in prevalence with age.
- Previous research highlights CMV's role in various pathological conditions.
Purpose:
- To investigate the seroprevalence of Cytomegalovirus (CMV) in different populations within Mexico.
- To compare CMV seropositivity rates in Chiapas and Mexico City with international data.
- To discuss the seroepidemiological characteristics and implications of CMV infection.
Summary:
- A high prevalence of CMV infection, indicated by CF antibodies, was found in the studied groups from Chiapas, Mexico, with 45% seropositivity in Lacanjá.
- Lower CMV seropositivity levels were observed in children from Mexico City compared to Chiapas, but higher than in some US populations.
- The findings suggest wide dissemination of CMV in the studied Mexican regions.
Impact:
- Provides crucial seroepidemiological data on CMV infection in specific Mexican populations.
- Highlights regional variations in CMV prevalence within Mexico.
- Informs public health strategies and future research on CMV's impact on human health, especially in developing regions.
