Insights

Coxsackievirus A6 caused a large hand, foot, and mouth disease (HFMD) outbreak in Thailand in 2012. Monitoring HFMD causes is crucial for effective prevention and control strategies.

Area of Science:

  • Virology
  • Epidemiology
  • Public Health

Background:

  • Hand, foot, and mouth disease (HFMD) is a common infectious illness in Thailand.
  • Enterovirus 71 and coxsackievirus A16 are typically identified as the causative agents of HFMD.
  • A significant HFMD outbreak occurred in Thailand between June and August 2012.

Purpose of the Study:

  • To identify the specific enterovirus responsible for the 2012 HFMD outbreak in Thailand.
  • To inform public health strategies for managing future HFMD outbreaks.

Main Methods:

  • Patient specimens from the 2012 HFMD outbreak were collected and analyzed.
  • Enterovirus typing was performed to identify the causative viral strain.

Main Results:

  • Coxsackievirus A6 was identified as the primary etiological agent of the 2012 HFMD outbreak.
  • This finding contrasts with the usual identification of enterovirus 71 or coxsackievirus A16.

Conclusions:

  • Coxsackievirus A6 emerged as a significant cause of HFMD in Thailand during the 2012 outbreak.
  • Continuous surveillance of HFMD causative agents is essential for timely and effective disease control.

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
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...
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...
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,...
Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
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...
