Insights

Asymptomatic norovirus (NoV) infections are common in children living in periurban Mexico City during summer. This study found nearly half of the pediatric participants had NoV, highlighting its prevalence in this population.

Area of Science:

  • Pediatric infectious diseases
  • Gastroenterology
  • Virology

Background:

  • Norovirus (NoV) is a leading cause of gastroenteritis globally.
  • Understanding asymptomatic infections is crucial for disease control.
  • Data on pediatric NoV in Latin America is limited.

Purpose of the Study:

  • To determine the prevalence of asymptomatic norovirus (NoV) infection in children.
  • To investigate the occurrence of NoV during the summer season.
  • To assess the burden of NoV in a periurban Mexican pediatric population.

Main Methods:

  • Stool specimens were collected from 63 children in periurban Mexico City.
  • Samples were tested for norovirus (NoV) detection.
  • Data collection occurred between June and August 1998.

Main Results:

  • Norovirus (NoV) was detected in 48 of 161 stool specimens (29.8%).
  • 31 children (49.2%) tested positive for NoV in at least one stool sample.
  • Asymptomatic NoV infection was frequently observed.

Conclusions:

  • Asymptomatic norovirus (NoV) infection is common in Mexican children during summer.
  • The findings suggest a significant role of asymptomatic carriers in NoV transmission.
  • Further research is needed to understand the long-term impact and transmission dynamics.

Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
