Insights

Congenital rubella infection was detected in 15.2% of infants using IgM antibody tests. Common signs included congenital cataracts and enlarged liver/spleen in infected newborns.

Area of Science:

  • Pediatrics
  • Virology
  • Immunology

Background:

  • Congenital infections pose significant risks to newborns.
  • Rubella virus infection during pregnancy can lead to severe infant health issues.

Purpose of the Study:

  • To determine the prevalence of rubella specific IgM antibodies in infants suspected of congenital infections.
  • To identify common clinical manifestations associated with congenital rubella infection.

Main Methods:

  • A cohort of 342 infants with suspected congenital infections was analyzed.
  • Serum samples were tested for rubella specific IgM antibodies using microplate enzyme-linked immunosorbent assay (mu ELISA).

Main Results:

  • 52 out of 342 infants (15.2%) tested positive for rubella specific IgM antibodies.
  • The most frequent clinical signs observed in IgM-positive infants were bilateral congenital cataracts and hepatosplenomegaly.

Conclusions:

  • Congenital rubella infection is a notable concern in infants presenting with specific symptoms.
  • Early detection of rubella specific IgM antibodies is crucial for identifying infected infants and managing potential complications.

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
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...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
