Measles Overview Quiz

Study Notes

Measles: Overview

Measles is a highly contagious viral illness primarily affecting children.
Characterized by a distinctive rash and a range of systemic symptoms.
Caused by the rubeola virus, a paramyxovirus.

Symptoms

Initial symptoms often resemble the common cold, including fever, cough, runny nose, and conjunctivitis (red, watery eyes).
A characteristic maculopapular rash develops, typically starting behind the ears and spreading over the face, neck, and body.
The rash often lasts for several days and can be accompanied by Koplik's spots (small white spots inside the mouth).
Other symptoms may include headache, fatigue, and loss of appetite.
Severity of symptoms can vary.

Transmission

Highly contagious through respiratory droplets.
Spread occurs through direct contact with infected individuals or by inhaling droplets from coughs or sneezes.
Infectious period typically begins a few days before the rash appears and continues for about a week after its onset.

Complications

Measles can cause a range of potentially serious complications, including:
- Pneumonia (inflammation of the lungs): a frequent cause of death in unvaccinated individuals.
- Encephalitis (inflammation of the brain): although rare, a potentially fatal complication that can lead to neurological problems.
- Middle ear infections (otitis media): common complication in children.
- Diarrhoea
- Bronchitis
- Blindness
- Death
Malnutrition and weakened immune systems can increase the risk and severity of complications.
The risk of complications is higher in infants, young children, and those with weakened immune systems.

Vaccination

Measles vaccination is proven to be highly effective in preventing the disease.
It is a safe and crucial part of childhood immunization schedules globally.
Vaccines are highly effective in preventing complications and outbreaks.
Vaccination is typically administered in multiple doses.
Two doses of measles vaccine are recommended for optimal protection.

Epidemiology

Measles is endemic in many parts of the world, especially in regions with lower vaccination coverage.
Outbreaks can occur quickly and spread rapidly.
Factors contributing to outbreaks include inadequate vaccination coverage, weakened public health infrastructure, and population movement.
Geographic clustering of cases may highlight areas needing intervention or increased awareness.
Measles poses significant risks to vulnerable populations, underscoring the importance of maintaining high vaccination rates.
Surveillance of cases helps to assess the spread and severity of outbreaks in localized populations.
