Study Notes

Statutorily Notifiable Infectious Diseases

A list of infectious diseases mandated for reporting includes acute poliomyelitis, amoebic dysentery, anthrax, bacillary dysentery, cholera, COVID-19, and more.
The diseases listed require careful monitoring for public health safety.

Chickenpox Overview

Chickenpox is classified as a mild disease that typically resolves on its own.
Severe complications may arise in vulnerable groups such as immunocompromised individuals and pregnant women, which can lead to pneumonia or encephalitis.
Infants infected with chickenpox face a higher risk of severe illness and potential mortality.
Early pregnancy infections can result in congenital defects in the fetus.

Diagnosis of Chickenpox

Contact history is crucial for initial assessment.
Diagnosis is visually based on the characteristic rash.
Laboratory tests involve collecting fluid from blisters and blood samples to detect varicella-zoster virus (VZV) presence.

Treatment for Chickenpox

Severe cases require hospitalization, isolation, and treatment with antibiotics and antiviral medications (e.g., Acyclovir).
Maintaining proper hygiene, such as keeping nails short and skin clean, is essential to avoid secondary bacterial infections.
Use of antihistamines may help relieve itching.

Prevention of Chickenpox

Good personal hygiene practices, including regular hand washing, are vital.
Environmental sanitation through regular cleaning of surfaces is recommended to prevent transmission.
Vaccination against chickenpox is important, achieving approximately 90% immunity in recipients.

COVID-19 Overview

COVID-19 is caused by the "Severe Acute Respiratory Syndrome Coronavirus 2" (SARS-CoV-2).
The main mode of transmission is through respiratory droplets, with potential contact spread.
Incubation period ranges from 1 to 14 days, with variants like Omicron posing shorter periods of around 3 days.

Clinical Symptoms of COVID-19

Common symptoms include fever, dry cough, fatigue, loss of taste or smell, sore throat, and gastrointestinal issues.
Severe outcomes can involve respiratory distress, chest pain, or confusion, particularly in high-risk populations.

Complications Associated with COVID-19

Complications may include respiratory failure, sepsis, or multi-organ dysfunction.
A rare but severe condition known as Multisystem Inflammatory Syndrome in Children (MIS-C) may occur post-infection.
"Long COVID" can affect up to 20% of individuals, with lingering symptoms such as fatigue and cognitive difficulties.

Diagnosis of COVID-19

Confirmatory tests like RT-PCR or rapid antigen testing are conducted on respiratory samples.

Treatment for COVID-19

Treatment focuses on supportive care, symptom relief, and antiviral therapies.

Prevention of COVID-19

Vaccination significantly reduces the severity and mortality rates associated with the disease.
Non-pharmaceutical interventions, such as social distancing and mask-wearing, remain crucial in preventing spread.

Hantavirus Infection

Hantavirus presents in two major forms: Hemorrhagic Fever with Renal Syndrome (HFRS) and Hantavirus Pulmonary Syndrome (HPS).
Transmission occurs primarily through rodent droppings, urine, or saliva.
Symptoms can vary from flu-like to severe respiratory distress, with HPS having a mortality rate of about 40%.

Prevention of Hantavirus Infection

Maintaining hygiene and cleanliness in living spaces is critical to preventing the accumulation of rodents.
Avoid direct handling of wild rodents or their nesting areas, especially in endemic regions.

Additional Protective Measures

Routine hand hygiene is essential to limit disease transmission.
Use disposable equipment and protective gear to mitigate risk in healthcare settings.
Regular sanitization of surfaces and proper waste management can help reduce transmission risks within communities.
