1. Introduction

Measles is a highly contagious viral infection that primarily affects children but can occur in individuals of any age. It is characterized by a distinctive rash, high fever, and other flu-like symptoms. While measles can be prevented through vaccination, outbreaks still occur in regions with low immunization rates. In this article, we will explore the definition, causes, and symptoms of measles, as well as discuss preventive measures and treatment options.

2. What are Measles?

Measles, also known as rubeola, is an infectious disease caused by the measles virus, belonging to the paramyxovirus family. It is highly contagious and spreads from person to person through respiratory droplets when an infected individual coughs or sneezes. The virus can survive in the air or on surfaces for several hours, making it easily transmissible.

3. Causes of Measles

The primary cause of measles is infection with the measles virus. The virus can enter the body through the respiratory system when an individual inhales airborne respiratory droplets containing the virus. Once inside the body, the virus replicates in the respiratory tract and then spreads throughout the body via the bloodstream, leading to systemic symptoms.

4. Transmission of Measles

Measles is highly contagious, and transmission occurs through close contact with an infected person. The virus can spread through:

• Airborne droplets: When an infected person coughs or sneezes, tiny droplets containing the virus become suspended in the air and can be inhaled by others nearby.
• Contaminated surfaces: The virus can survive on surfaces for a few hours, and if someone touches these surfaces and then touches their nose, mouth, or eyes, they can become infected.

5. Symptoms of Measles

The symptoms of measles typically appear around 10 to 14 days after exposure to the virus. Initial symptoms may include:

• High fever: Measles often begins with a high fever, which may reach 103-105°F (39-40.6°C).
• Cough: A persistent cough is common, along with a runny nose and sneezing.
• Sore throat: The throat may become red and sore.
• Conjunctivitis: Also known as pink eye, it causes redness, itching, and discharge in the eyes.
• Koplik spots: Small, white spots with a bluish-white center may appear on the inner lining of the cheek, opposite the molars.

After a few days, a distinctive rash appears, which spreads from the head to the rest of the body. Other symptoms during this stage may include:

• Widespread rash: The rash consists of small, red, and raised bumps that merge together.
• Fever spike: The fever may spike again during the rash stage.
• Generalized discomfort: Children and adults with measles may experience overall discomfort, body aches, and fatigue.
• Loss of appetite: Many individuals with measles experience a reduced appetite.
• Enlarged lymph nodes: The lymph nodes in the neck and
