Pediatric Infectious Diseases

Pediatric Infectious Diseases

Infectious diseases are one of the most common reasons why children fall ill. The infections can be mild or, in rare cases, life-threatening and depend on the age of the child. Highly trained and experienced doctors at our Department of Pediatric Surgery help provide the best possible medical care.

What we commonly see in day-to-day practice

  • Viral fevers
    Often present with low to moderate fever, runny nose, and mild body ache, especially during school-going months.
  • Respiratory infections (including RSV)
    Seen in younger children with cough, fast breathing, or wheeze, sometimes with chest indrawing below the ribs.
  • Hand-foot-mouth disease
    Small fluid-filled lesions over palms, soles, and inside the oral cavity, usually with mild fever.
  • Gastroenteritis
    Frequent loose stools (often 4–6 episodes/day), sometimes with vomiting and mild abdominal discomfort around the umbilical region.
  • Bacterial infections (throat/ear)
    Typically present with higher fever and localized pain, such as difficulty swallowing or ear pain worsening at night.

  • Persistent high fever
    Fever lasting more than 3 days or rising above 39°C may need further evaluation.
  • Fast or laboured breathing
    More than 50 breaths per minute in toddlers or visible chest retractions along the lower rib margin.
  • Reduced urine output
    Fewer than 3–4 wet diapers in 24 hours in infants, suggesting dehydration.
  • Repeated vomiting or loose motions
    Especially when oral intake is poor, and the child appears weak.
  • Behavioral changes
    Unusual drowsiness, irritability, or reduced interaction, sometimes more significant than the fever itself.

Parents are often confused between viral and bacterial infections. Viral infections usually begin gradually. There may be a runny nose, mild fever, and the child still plays intermittently. These infections often settle within 3–5 days with fluids and symptomatic care. Bacterial infections tend to present more abruptly. Fever may be higher. Pain is often localized, such as sharp throat pain while swallowing, or ear pain when lying flat. On examination, we may see findings like pus over the tonsillar surface or a congested, bulging tympanic membrane. That said, the distinction is not always clear on day one. Sometimes, we watch, reassess, and only then decide on antibiotics.

Seasonal patterns are fairly consistent in this region. During the monsoon, we see an increase in dengue and malaria. A child presenting with high fever, body ache behind the knees or elbows, and falling platelet counts raises concern for dengue.

Post-monsoon, viral fevers tend to linger, and typhoid may appear in some children. Winter months bring more respiratory infections, persistent cough, throat discomfort, and occasional wheezing. These patterns guide suspicion, but confirmation is always clinical, sometimes supported by investigations.

Vaccination discussions are part of almost every consultation. Routine immunization protects against serious illnesses such as measles, polio, and diphtheria, and should not be delayed without reason. Optional vaccines, like influenza (annual), typhoid, and chickenpox, are often recommended based on exposure risk, especially for school-going children. Many parents worry about missed doses; in most cases, a structured catch-up schedule can be planned without restarting the series.

  • Hand hygiene
    Washing hands before meals and after outdoor play reduces transmission significantly.
  • Avoiding shared items
    Water bottles, spoons, and tiffin sharing in school settings can spread infections.
  • Early isolation
    Keeping a child at home during the first 48–72 hours of fever may limit spread within families and classrooms.
  • Nutrition and fluids
    Small, frequent feeds with adequate fluids help maintain energy and hydration, even if appetite is reduced.

Care is often individualized. A child with recurrent infections may require evaluation beyond routine consultation, sometimes involving ENT or respiratory specialists. Investigations are advised selectively. Blood tests, chest imaging, or throat swabs are used when they change management, not routinely. Treatment depends on cause; viral illnesses are usually managed with hydration, paracetamol, and observation. Antibiotics, when required, are prescribed carefully and typically reviewed within 48–72 hours for response. We are committed to helping children with infectious conditions with the best treatment in Navi Mumbai.

Most childhood infections are self-limiting. Still, a small proportion may evolve differently. Recognizing warning signs early makes a significant difference. In many cases, the diagnosis begins not with a test, but with observation: how the child walks in, responds, and interacts. That often tells us more than any report.
