Measles, a highly contagious viral infection, is once again a public health concern. While once considered largely eradicated in the United States, recent declines in vaccination rates have led to outbreaks, prompting renewed attention to the disease’s symptoms, risks, and prevention. Understanding the signs of measles and knowing when to seek medical attention is crucial for protecting both individuals and communities.
What is Measles?
Measles, also known as rubeola, is caused by a virus that initially infects the respiratory tract before spreading throughout the body. It’s exceptionally contagious – approximately 90% of individuals who are not immune to the virus will become infected if exposed. The virus can linger in the air for up to two hours after an infected person leaves a room, making it easily transmissible. While most people recover, measles can lead to serious health complications, particularly in young children, adults over 20, and individuals with compromised immune systems.
Recognizing the Symptoms
The initial symptoms of measles typically appear after exposure to the virus and often mimic a common cold. These early signs include a high fever – which may spike to over – a persistent cough, a runny nose, and red, watery eyes (conjunctivitis).
Within a few days, distinctive spots called Koplik spots may appear inside the mouth. These are tiny white spots that can serve as an early indicator of measles. Following the appearance of Koplik spots, typically after the initial symptoms, a rash develops. This rash usually begins as flat, red spots at the hairline and then spreads downward, covering the neck, trunk, arms, legs, and feet. Small, raised bumps may also form on top of the flat red spots, and the spots can merge together as they spread across the body. The fever often rises again when the rash appears.
Potential Complications
Measles isn’t simply a rash and a fever; it can lead to several complications. Common complications include ear infections, affecting about one in ten children with measles, and diarrhea, reported in less than one in ten people. However, more serious complications can occur, emphasizing the importance of seeking appropriate medical care.
When to Seek Medical Attention
If you suspect you or your child has been exposed to measles, it’s vital to contact your healthcare provider immediately. According to the Centers for Disease Control and Prevention (CDC), prompt medical attention is crucial. The Texas Department of State Health Services also advises seeking medical care if you believe you have measles, as symptoms can worsen over time and complications can develop.
While most cases can be managed with supportive care, it’s important to be aware of situations that warrant emergency medical attention. The specific criteria for emergency care vary, but generally include a worsening of symptoms or the development of severe complications.
How Measles Spreads
The measles virus is spread through respiratory droplets produced when an infected person coughs or sneezes. It can also be contracted by touching contaminated surfaces and then touching your eyes, nose, or mouth. An infected person is contagious from before the rash appears until after. This period of contagiousness before obvious symptoms develop makes containment challenging without vaccination and early diagnosis.
Prevention: The Role of Vaccination
The most effective way to protect against measles is vaccination. The measles, mumps, and rubella (MMR) vaccine is highly effective, providing long-lasting immunity. Two doses of the MMR vaccine are recommended for children, with the first dose typically administered between of age and the second dose between of age. Adults who have not been vaccinated or who are unsure of their vaccination status should also consult with their healthcare provider about receiving the MMR vaccine.
Protecting vulnerable populations relies on maintaining high vaccination rates within communities. When a significant portion of the population is immune to measles, it creates “herd immunity,” which helps to prevent the spread of the virus and protect those who cannot be vaccinated, such as infants too young to receive the vaccine or individuals with certain medical conditions.
The recent resurgence of measles underscores the importance of vaccination and vigilance. By understanding the symptoms, risks, and prevention strategies, individuals can play a role in protecting themselves and their communities from this highly contagious disease.
