Khasra Disease: Overview
Khasra, also known as measles, is a highly contagious viral infection caused by the measles virus. It primarily affects children but can also occur in unvaccinated adults. The disease is characterized by a distinctive rash, fever, and respiratory symptoms. Despite the availability of an effective vaccine, measles outbreaks continue to occur in various parts of the world, particularly in areas with low vaccination coverage. Understanding the causes, symptoms, types, and treatment of Khasra is essential for managing the disease and preventing its spread.
Causes of Khasra Disease
Khasra disease is caused by the measles virus, which is part of the paramyxovirus family. The virus spreads through respiratory droplets when an infected person coughs, sneezes, or talks. It can also survive on surfaces for several hours, making indirect transmission possible. The virus is highly contagious, with approximately 90% of non-immune individuals contracting the disease after exposure.
Immunization is the primary method of prevention. The measles, mumps, and rubella (MMR) vaccine is administered in childhood and provides immunity against the disease. However, some individuals may remain unvaccinated due to various reasons, including misinformation about vaccines, accessibility issues, or personal beliefs. In addition, those with weakened immune systems, such as infants too young to be vaccinated or individuals undergoing immunosuppressive treatments, are particularly vulnerable to Khasra.
Symptoms of Khasra Disease
The symptoms of Khasra typically appear about 10 to 14 days after exposure to the virus. The initial signs often resemble those of a common cold and may include:
- Fever: A high fever is one of the first symptoms, often reaching temperatures of 104°F (40°C) or higher.
- Cough: A dry cough usually develops alongside the fever.
- Runny nose: Nasal congestion and a runny nose are common.
- Conjunctivitis: Red, inflamed eyes may occur due to inflammation of the conjunctiva.
After a few days, the characteristic rash appears. The rash usually starts at the hairline and spreads downwards to the face, neck, and body. It consists of small, red spots that may merge to form larger patches. Koplik spots, tiny white spots with bluish centers, may also appear inside the mouth a few days before the rash.
Other symptoms may include sensitivity to light, fatigue, and a general feeling of malaise. While most individuals recover without complications, Khasra can lead to severe health issues, particularly in young children and immunocompromised individuals. Potential complications include pneumonia, encephalitis, and diarrhea, which can pose significant health risks.

Types of Khasra Disease
Khasra disease can be classified into different types based on the severity of the infection and associated complications:
- Typical Measles: This is the classic presentation, characterized by the typical symptoms, including fever, cough, and the distinctive rash. Most cases of Khasra fall into this category.
- Atypical Measles: This occurs in individuals who have been vaccinated but still contract the virus. Symptoms may be less severe and can present differently from typical measles. Atypical cases may involve milder rashes or fever.
- Severe Measles: This form can lead to serious complications such as pneumonia, encephalitis, or severe diarrhea. Severe measles is more common in malnourished children or those with weakened immune systems.
- Subacute Sclerosing Panencephalitis (SSPE): This rare but serious complication can occur 7 to 10 years after a measles infection. It leads to progressive neurological decline, seizures, and eventually death. SSPE is more likely to develop in individuals who contracted measles at a young age.
Recognizing the type of Khasra disease is crucial for appropriate management and treatment.
Treatment of Khasra Disease
Treatment for Khasra primarily focuses on alleviating symptoms and managing complications. There is no specific antiviral treatment for the measles virus, so supportive care is essential. Key components of treatment include:
- Hydration: Ensuring that the patient remains hydrated is vital, especially if they experience fever or diarrhea. Oral rehydration solutions may be used for mild dehydration, while intravenous fluids may be necessary in severe cases.
- Antipyretics: Fever reducers, such as acetaminophen or ibuprofen, can help manage high fever and discomfort. It’s essential to follow the appropriate dosage guidelines based on the patient’s age and weight.
- Rest: Adequate rest is crucial for recovery. Patients should be encouraged to rest and avoid strenuous activities during the illness.
- Nutritional Support: A balanced diet can aid in recovery. In cases where the patient has difficulty eating due to mouth sores or gastrointestinal symptoms, soft foods and easy-to-digest options are recommended.
- Vitamin A Supplementation: Vitamin A has been shown to reduce the risk of complications and improve recovery in individuals with Khasra. Supplementation is particularly important for malnourished children.
In severe cases or when complications arise, hospitalization may be necessary. Treatment may involve antibiotics for secondary bacterial infections, intravenous fluids, and specialized care for pneumonia or neurological complications. Vaccination remains the most effective means of prevention, and it is essential to encourage vaccination in the community to protect vulnerable populations.
