Insights

A child with fever and breathlessness was diagnosed with myocarditis caused by Chikungunya virus (CHIKV). Prompt management led to full recovery, suggesting potential cardiac effects of CHIKV.

Area of Science:

  • Pediatric infectious diseases
  • Cardiology
  • Virology

Background:

  • Chikungunya virus (CHIKV) infection can present with diverse clinical manifestations.
  • Cardiac involvement in CHIKV, particularly in pediatric cases, is not well-documented.

Observation:

  • A 5-year-old boy presented with high-grade fever, cervical adenitis, myalgia, arthralgia, and acute breathlessness.
  • Clinical, electrocardiographic, and echocardiographic findings indicated myocarditis and congestive cardiac failure.

Findings:

  • Serum IgM antibodies to CHIKV were detected via MAC-IgM ELISA 5 days post-onset.
  • The child showed symptomatic improvement within 3 days of conservative management.
  • Repeat echocardiography at discharge revealed normal left ventricular function and mild mitral regurgitation.

Implications:

  • This case highlights the potential for Chikungunya virus to cause significant cardiac complications in children.
  • Early diagnosis and supportive care are crucial for managing CHIKV-induced myocarditis.
  • Further research into the cardiac tropism of CHIKV is warranted.

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...
Chickenpox01:20

Chickenpox

Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Cholera01:25

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,...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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...
Yellow Fever01:18

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
