measles disease
Introduction
Measles, also known as rubeola, is a highly contagious viral disease caused by the measles virus. Despite being preventable through vaccination, measles remains a significant cause of morbidity and mortality worldwide, particularly in regions with low vaccination coverage.
Causes and Transmission
Measles is caused by the measles virus, a member of the paramyxovirus family. It spreads through respiratory droplets when an infected person coughs or sneezes. The virus can remain active and contagious on surfaces and in the air for up to two hours. Individuals are contagious from four days before to four days after the appearance of the characteristic rash.
Symptoms
Measles symptoms typically appear 10-14 days after exposure to the virus. Early symptoms include high fever, cough, runny nose, and red, watery eyes (conjunctivitis). Koplik’s spots, small white spots inside the mouth, may appear 2-3 days before the rash. The rash itself usually starts on the face and upper neck and then spreads downwards to the rest of the body.
Complications
While most people recover from measles without serious issues, complications can occur, particularly in children under five and adults over 20. These complications include:
Pneumonia: A severe lung infection that can be life-threatening.
Encephalitis: Swelling of the brain, which can lead to convulsions, deafness, or intellectual disabilities.
Ear infections: Can result in permanent hearing loss.
Diarrhea and dehydration.
Prevention
Vaccination is the most effective way to prevent measles. The measles, mumps, and rubella (MMR) vaccine is highly effective and safe. It is typically administered in two doses, with the first dose given at 12-15 months of age and the second dose at 4-6 years of age. High vaccination coverage is crucial to achieve herd immunity and prevent outbreaks.
Global Impact and Efforts
Despite the availability of a safe and effective vaccine, measles remains a major public health issue, especially in areas with low vaccination rates. According to the World Health Organization (WHO), over 140,000 people died from measles in 2018, mostly children under five. The global resurgence of measles is attributed to inadequate vaccination coverage and vaccine hesitancy.
International efforts, including mass vaccination campaigns and strengthening routine immunization programs, are essential to control and eventually eradicate measles. Organizations like WHO and UNICEF play a critical role in these efforts, especially in low-income countries with limited healthcare infrastructure.
Measles is a preventable but highly contagious disease that continues to pose a significant health threat globally. Vaccination is the key strategy to prevent measles and its complications. Strengthening immunization programs and addressing vaccine hesitancy are vital to reduce the global burden of this disease.
Causes of measles disease
Measles is caused by the measles virus, a highly contagious pathogen from the Paramyxoviridae family. Here are the primary causes and modes of transmission:
Virus and Transmission
Measles Virus: The disease is caused by the measles virus, which infects the respiratory system.
Airborne Transmission: The virus spreads through respiratory droplets when an infected person coughs or sneezes. These droplets can remain airborne or settle on surfaces, where the virus can stay active and contagious for up to two hours.
Direct Contact: Measles can also spread through direct contact with infectious droplets or contaminated surfaces. If a person touches a contaminated surface and then touches their face, they can contract the virus.
Highly Contagious: Measles is one of the most contagious diseases known. An individual with measles can infect 90% of non-immune people close to them. The contagious period starts from about four days before the rash appears to four days after it erupts.
Factors Contributing to the Spread
Low Vaccination Rates: The primary cause of measles outbreaks is inadequate vaccination coverage. The measles, mumps, and rubella (MMR) vaccine is highly effective, but regions with low vaccination rates are prone to outbreaks.
Vaccine Hesitancy: Misinformation and skepticism about vaccine safety have led to increased vaccine hesitancy, reducing herd immunity and allowing the virus to spread.
Travel: International travel can introduce the virus to areas previously free of measles, especially when travelers from regions with ongoing outbreaks visit or return to their home countries.
High Population Density: Crowded living conditions and high population density facilitate the rapid spread of the virus.
Malnutrition and Vitamin A Deficiency: Inadequate nutrition, particularly vitamin A deficiency, can weaken the immune system, making individuals more susceptible to severe measles infections and complications.
Prevention
Vaccination: The MMR vaccine is the most effective measure to prevent measles. It is typically administered in two doses, with the first dose given at 12-15 months and the second dose at 4-6 years.
Herd Immunity: Achieving high vaccination coverage (around 95%) is essential to maintain herd immunity and prevent outbreaks.
Public Health Initiatives: Mass vaccination campaigns, public health education, and international cooperation are vital to increasing vaccination rates and reducing the spread of measles.
Suggested Medications for Treating measles disease
While there is no specific antiviral treatment for measles, the management of the disease focuses on alleviating symptoms and preventing complications. Here are some commonly recommended medications and treatments:
Symptom Relief of measles disease
Antipyretics (Fever Reducers):
Acetaminophen (Paracetamol): Used to reduce fever and relieve pain. It is generally safe for both children and adults.
Ibuprofen: Another option for reducing fever and pain. It should be used with caution and according to a healthcare provider’s guidance, especially in children.
Hydration:
Oral Rehydration Solutions: Important for preventing dehydration, especially if the patient has diarrhea or is not eating or drinking well. Drinking plenty of fluids such as water, fruit juices, and oral rehydration solutions is recommended.
Managing Complications
Vitamin A:
Vitamin A Supplements: The World Health Organization (WHO) recommends vitamin A supplementation for children diagnosed with measles. This can help reduce the severity of the disease and prevent complications, such as blindness and severe diarrhea.
Antibiotics:
For Secondary Bacterial Infections: While antibiotics are not effective against the measles virus itself, they may be prescribed if there are secondary bacterial infections, such as bacterial pneumonia or ear infections.
Cough Remedies:
Honey and Lemon: For children over one year of age, honey can help soothe a sore throat and cough.
Humidifiers: Using a cool-mist humidifier can help alleviate cough and throat irritation.
Eye Care:
Lubricating Eye Drops: To relieve discomfort from conjunctivitis, lubricating eye drops may be recommended.
General Care
Rest:
Adequate Rest: Ensuring the patient gets plenty of rest to help the body fight off the infection.
Isolation:
Preventing Spread: Keeping the patient isolated from others, especially those who are not immunized, to prevent the spread of the virus.
Preventive Measures
Vaccination:
MMR Vaccine: The measles, mumps, and rubella (MMR) vaccine is the most effective preventive measure. It is usually administered in two doses, the first at 12-15 months and the second at 4-6 years of age.
Boosting Immunity:
Healthy Diet: Maintaining a healthy diet to support the immune system can help in recovery.
