nsch 3.1.4 Communicable Diseases in Children

Overview of Communicable Diseases in Children

  • Communicable diseases primarily affect children due to their developing immune systems.

  • Key diseases include: Polio, Measles, Mumps, Rubella, Round worms, Hookworms, and Tapeworms.

Definition of Communicable Diseases

  • Definition: A communicable disease is an illness caused by the transmission of an infectious agent from an infected person, animal, or reservoir to a susceptible host through various means including droplets, contact, or environmental exposure (Clarke, 2016:153).

Communicable Diseases in Depth

Mumps

  • General Description: Mumps, also known as infectious parotitis, is a viral infection targeting the salivary glands, particularly the parotid gland.

  • Causative Organism: Paramyxovirus (related to the measles virus).

  • Incubation Period: 14-24 days.

  • Route of Transmission: Spread via droplet infection through coughing/sneezing or direct contact with saliva.

Pathogenesis

  • Infection begins in the upper respiratory tract or gastrointestinal tract, subsequently spreading to lymphoid tissue, resulting in primary viremia and potentially affecting the parotid gland, central nervous system, testes, or pancreas.

Clinical Manifestations

  • Early Stage: Fever, sore throat, pain while eating or swallowing, nausea, malaise, headaches.

  • Advanced Stage: Painful swelling of parotid glands, tenderness.

    • Note: Bilateral swelling may give a "hamster-like" appearance.

Diagnosis

  • Clinical Diagnosis: Based on visual and verbal symptoms.

  • Laboratory Diagnosis: Increased mumps virus antibody titre indicates recent infection.

Complications

  • Infections post-puberty can lead to orchitis (inflammation of testes), meningitis, encephalitis, pancreatitis, nephritis, painful joints.

  • Emergency signs include high fever, severe headache, abdominal pain, painful testes, suspected meningeal or encephalitic symptoms.

Management

  • Nursing Care: Patient isolation, bed rest, good hygiene practices, fluid intake, soft diet, application of heat/cold for relief.

  • Medical Management: Paracetamol for pain and fever management.

Measles

  • General Description: Measles (rubeola) is a highly infectious respiratory condition, particularly dangerous in malnourished children and those with HIV/AIDS.

  • Causative Organism: Paramyxovirus.

  • Incubation Period: 4-12 days.

  • Route of Transmission: Through respiratory droplets and direct contact with nasal/throat secretions.

Pathogenesis

  • The virus infects epithelial cells of the throat and lungs; can also replicate in various body systems.

Clinical Manifestations

  • Symptoms: Cold symptoms, fever (up to 40.6°C) for at least three days, the three C's (Cough, Coryza, Conjunctivitis), Koplik’s spots in the mouth.

  • Rash: Generalized maculopapular rash starting from the head and spreading to the body, lasting 5-6 days.

Diagnosis

  • Based on clinical symptoms (history of fever, C's, rash), and positive blood tests for measles IgM antibodies.

Complications

  • Includes diarrhea, encephalitis, corneal ulceration, and increased secondary bacterial infections (e.g., bronchitis).

Nursing Interventions

  • Control light exposure, ensure hydration, monitor for complications, and maintain hygiene.

Rubella

  • General Description: Rubella (German measles) is less severe than measles, characterized by a short duration rash.

  • Causative Organism: Togaviridae, genus Rubivirus.

  • Incubation Period: 14-21 days.

  • Transmission: Through respiratory droplets; can cross the placenta causing fetal infections.

Clinical Manifestations

  • Mild maculopapular rash, fever, and swollen lymph nodes.

Complications

  • Severe congenital defects if infected during pregnancy leading to congenital rubella syndrome (CRS).

Nursing and Medical Management

  • Isolate from pregnant women, ensure hydration, provide symptomatic care, and monitor for complications.

Poliomyelitis

  • Description: An acute viral disease affecting the spinal cord, causing muscle weakness and paralysis.

  • Causative Organism: Poliovirus (types 1, 2 & 3).

  • Incubation Period: 3-35 days, typically through fecal-oral transmission.

Clinical Manifestations

  • Ranges from mild symptoms to severe paralysis (clinical and paralytic poliomyelitis).

Diagnosis and Management

  • Based on clinical signs and laboratory tests; supportive management is key.

Other Diseases
Roundworm, Hookworm, and Tapeworm (Acariasis, Ancylostomiasis, Taeniasis)

  • Focus on prevention through sanitation, treatment with anti-helminthic drugs, and health education around hygiene practices.

  • Roundworms can cause digestive problems, Hookworms lead to anemia and growth retardation, while Tapeworms generally require more invasive diagnostics but can result in weight loss and abdominal issues.

Conclusion

  • Understanding these communicable diseases is crucial for effective management and prevention, especially in vulnerable populations like children.

Other Helminth Infections in Detail
Roundworm (Ascariasis)

  • General Description: Roundworm infections are caused by the Ascaris lumbricoides parasite, which can grow quite large and live in the intestines. These worms can cause a range of digestive issues.

  • Symptoms: Mild infections may be asymptomatic, while severe infections can lead to abdominal pain, malnutrition, and intestinal blockage. Children may experience stunted growth and developmental issues due to nutritional deficiencies related to roundworm infections.

  • Transmission: Infection occurs through ingestion of eggs in contaminated food or water. Children are particularly at risk due to less rigorous handwashing practices.

Hookworm (Ancylostomiasis)

  • General Description: Hookworms are parasitic worms that enter the body through the skin (often through bare feet) and reside in the intestines, where they attach to the intestinal wall and feed on blood.

  • Symptoms: Symptoms can include anemia due to blood loss, fatigue, and abdominal pain. In children, chronic infection can lead to growth retardation and cognitive deficits due to iron deficiency.

  • Transmission: Hookworm larvae are often found in areas with poor sanitation, particularly in moist, warm, and sandy soil. Education on wearing shoes and improving sanitation is crucial for prevention.

Tapeworm (Taeniasis)

  • General Description: Tapeworms are flat, segmented worms that can infect humans through consumption of undercooked or contaminated meat containing cysts (e.g., pork or beef). They can live for years in the intestines.

  • Symptoms: Many people with tapeworm infections may have no symptoms; however, some can experience weight loss, digestive disturbances, and nutrient absorption issues. Prolonged infections can lead to more significant health problems.

  • Transmission: Tapeworm infections come from consuming contaminated food and maintaining good food safety practices is essential to prevent infections.

Prevention and Treatment Strategies

  • Prevention: Focus on good hygiene practices—frequent handwashing, proper food handling, and ensuring clean drinking water. Education on sanitation is critical to reduce the prevalence of these infections.

  • Treatment: Anti-helminthic medications are effective treatments for these parasitic infections. Monitoring of children in areas where these worms are endemic is critical for early detection and treatment. Regular screening and education can lead to better health outcomes for children.
