Respiratory infection in children Dubai: Common Viral Infections in children causing respiratory infections

Respiratory infection in children Dubai: Viral respiratory infections are common in children. Most of these infections are caused by respiratory syncytial virus (RSV), influenza virus A or B (FluV), parainfluenza virus (PIV), rhinovirus (RV), or adenovirus (AdV). Several recently discovered viruses, such as human metapneumovirus (HMPV), human bocavirus (HBoV), and the human coronaviruses (HCoVs) are also problems. 

Viral infections do not need antibiotics and usually subside on their own except for Influenza. 

Viral infections can cause high fevers, rhinitis, pharyngitis, sinusitis, bronchiolitis, bronchitis and pneumonia.

RSV

  • Respiratory Syncytial Virus is the most important cause of respiratory infection in young children worldwide
  • Immunity is feeble and fleeting, and repeated infections are the rule
  • One in every 100 or 200 infected infants requires hospitalization, usually for bronchiolitis.
  • Community-acquired RSV occurs mostly in winter
  • It is highly contagious and an infected child may drop the virus for days
  • The consequences of RSV infection can be especially dire for babies less than 6 months, children with underlying conditions such as prematurity, cardiac and pulmonary disease, or immunosuppression
  • Washing hands frequently, wearing masks and keeping sick children away from nurseries and daycare is essential

Influenza

  • Influenza is one of the most significant causes of acute upper respiratory tract infections worldwide
  • The common ones are Influenza A and B and sporadically Influenza C. Swine Flu (H1N1) and Avian Flu (H5N1) are also subtypes and are more dangerous
  • Influenza viruses are highly contagious and can cause seasonal epidemics and pandemics
  • Symptoms include high fever with chills, cold, cough, body ache, conjunctivitis and sometimes pneumonia
  • It can range from mild fatigue to respiratory failure and death
  • Influenza viruses mutate every year and thus immunity acquired is temporary
  • Tamiflu given early in the disease helps to reduce severity of symptoms

RhinoVirus

  • Rhinoviruses (RVs) chiefly cause upper respiratory tract infections, but may also infect the lower respiratory tract
  • RVs are the most common cause of the common cold
  • Although RV infections occur year-round, the incidence is highest in the fall and the spring
  • Symptoms are usually mild and differ in different ages
    • Infants and preschoolers – Fever possible of 38-39°C
    • Infants and toddlers – May have only nasal discharge
    • School-aged children – Nasal congestion, cough, and runny nose
  • Zinc spray or lozenges can shorten the infection

Adenovirus

  • It is a DNA virus and is very hardy and resistant to many disinfectants
  • It is highly contagious
  • Can be found on surfaces, objects, and water of swimming pools
  • It is a common cause of viral infections in children
  • There are several strains that can affect different systems like
    • The respiratory system causing cough, cold, croup, bronchitis, pneumonia
    • The GI system causing diarrhea
    • The eyes causing ‘pink eye’ or conjunctivitis
    • Bladder infections or cystitis
    • Rarely neurological disease
  • The incubation period is 2 to 5 days but the infected child can be contagious for weeks
