Clinical Manifestation of Adenovirus & Diseases Caused by Adenovirus Infection & its Treatment

What is Adenovirus?

Adenovirus is classified as Non-enveloped Ds-DNA virus. The virus contains double stranded DNA genetic amino acid chain. The viral infection is also known as common cold. The adenovirus infection attacks mucosal membrane of respiratory tract and conjunctiva. Adenovirus infection results in rhinitis, pharyngitis, bronchitis and keratoconjuctivitis. Adenoviral infection can cause life threatening multi organ infection in patient suffering with immunodeficiency syndrome. The adenovirus is divided in 5 subtypes known as mastadenovirus, avidenovirus, atadenovirus, siadenovirus and ichtadenovirus. The adenovirus starts rapidly multiplying once the virus enters into mucosal epithelial cells.

Adenovirus Infection

Clinical Manifestation of Adenovirus

Adenoviral infection causes keratoconjunctivitis, tonsillitis and infection of upper respiratory tract. The viral infection of upper respiratory tract is also known as strep throat, whooping cough or croup. There are several subtypes of adenovirus causing infection of gastrointestinal system resulting in gastroenteritis. Rarely few of subtypes of adenovirus causes viral meningitis and encephalitis. The spread of infection in mucosal membrane of urinary tract follows hemorrhagic cystitis and urinary tract infection.

Disease Caused by Adenovirus Infections

Upper Respiratory Tract Diseases Caused by Adenovirus Infection-

Symptoms Caused by Upper Respiratory Adenovirus Tract Infection-

  • Croup. Cough associated with hoarse voice and stridor seen in patient suffering with laryngotracheobronchitis
  • Cough
  • Expectoration
  • Throat Pain
  • Fever.

Lower Respiratory Tract Diseases Caused By Adenovirus Infection-

Symptoms Bronchiolitis-

  • Cyanosis resulting in blue lips and finger tips because of low oxygen in blood. Mostly seen in infants and young children.
  • Fever
  • Dehydration
  • Cough with expectoration.

Symptoms Pneumonia-

  • Treat body ache
  • Eye drops
  • Antiviral pills

Specific Treatment-

Treating Hemorrhagic Cystitis Caused Due to Adenovirus Infection-

  • Temporary packing to stop bleeding
  • Percutaneous insertion of tube in bladder to drained the blood and blood clot
  • Blood transfusion if needed
  • Hypogastric artery embolization to stop blood passing to urinary bladder
  • Cystectomy- removal of urinary bladder

Treating Pneumonia Due to Adenovirus Infection

  • Antiviral medication
  • Cough syrup

Treatment of Meningitis and Encephalitis Caused by Adenovirus Infection –

  • Antiviral medication
  • Treat low blood pressure with intravenous fluid and medications
  • Unconscious patient with breathing difficulties may be treated with intubation and ventilation.

Prevention of Adenovirus Infection

The vaccine to prevent recurrent adenovirus infection has been discontinued in USA and not produced for prevention. The disease caused by adenovirus infection is transmitted from infected child and adult in school, place of work and playroom. The disease transmission is prevented by avoiding the direct contact and avoiding sharing of toys, work related objects and frequent hand wash.
