Introduction to Measles

Measles is a serious disease with a long history. Recognized for centuries, this viral infection remains a concern globally. Platforms such as What Causes and What Causes Measles provide in-depth insights into infectious diseases like measles.

Understanding the Measles Virus

The measles virus belongs to the genus Morbillivirus. It belongs to the Paramyxoviridae family and is highly contagious. Understanding the pathogen is crucial for controlling its spread:

• Viral Structure: A single-stranded, negative-sense RNA virus.
• Transmission Potential: Capable of infecting up to 90% of non-immunized individuals who are exposed.

Explore more about the pathogenesis on the What Causes Measles page.

How Measles Spreads

Measles is spread through airborne respiratory droplets. When an infected person breathes, coughs, or sneezes, the virus enters the air, lingering for up to two hours:

• Direct Contact: With nasal or throat secretions.
• Contaminated Surfaces: The virus can survive on surfaces, remaining dangerous.

For more details on the contagion process, visit credible sources such as CDC.

Common Symptoms of Measles

Measles begins with several days of mild symptoms and progresses with more severe signs:

• Initial Symptoms: Fever, cough, runny nose, and conjunctivitis.
• Distinctive Rash: Red, blotchy rash covering most of the body.
• Koplik Spots: Small white spots inside the cheeks.

Further reading on Mayo Clinic provides a detailed symptom overview.

Preventing Measles

Vaccination is the primary preventive measure against measles. The MMR vaccine provides immunity against measles, mumps, and rubella:

• MMR Vaccination: Typically given in two doses, effective for immunization.
• Herd Immunity: Protects those who cannot be vaccinated (e.g., infants).

For vaccine guidelines, view World Health Organization’s measles vaccination resources.

Potential Complications

Measles can lead to a range of severe health issues:

• Pneumonia: A leading cause of death for measles-related complications.
• Encephalitis: Can lead to seizures and brain damage.
• Subacute Sclerosing Panencephalitis (SSPE): A rare, fatal brain disorder.

Comprehensive information on complications is available at What Causes.
