For most people, the measles virus does not cause a serious illness. Symptoms include fever and a rash, but the symptoms are usually gone in about a week. However, for some, the measles virus can be much more serious. How can the measles virus cause a potentially fatal illness? a. Measles can cause meningococcal disease, which causes severe headaches, seizures and in severe cases can be life-threatening. b. Measles can cause variant Creutzfeldt–Jakob disease, which causes severe headaches, seizures and in severe cases can be life-threatening. c. Measles can cause encephalitis/meningitis, which causes severe headaches, seizures and in severe cases can be life-threatening. d. Measles can cause Legionnaires’ disease, which causes severe headaches, seizures and in severe cases can be life-threatening.

Step by step solution

01

- Understanding the Question

The question is asking how the measles virus can cause a potentially fatal illness. It provides four options, each linking measles to a different severe disease.

02

- Analyze Option a

Option a states that measles can cause meningococcal disease. Meningococcal disease is a severe bacterial infection, not related to the measles virus.

03

- Analyze Option b

Option b states that measles can cause variant Creutzfeldt–Jakob disease (vCJD). vCJD is a prion disease not caused by the measles virus.

04

- Analyze Option c

Option c states that measles can cause encephalitis/meningitis. Measles can indeed cause encephalitis, which is an inflammation of the brain that can lead to severe headaches, seizures, and can be life-threatening.

05

- Analyze Option d

Option d states that measles can cause Legionnaires’ disease. Legionnaires’ disease is caused by a bacterium called Legionella pneumophila and is not associated with the measles virus.

06

- Selecting the Correct Answer

From the analysis, option c is the only one correctly linking measles to a potentially fatal condition, encephalitis/meningitis.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

viral encephalitis

Viral encephalitis is a serious condition where the brain becomes inflamed due to a viral infection. This inflammation can cause the brain to swell, leading to various concerning symptoms. The measles virus can indeed cause viral encephalitis.

Symptoms of viral encephalitis caused by measles include severe headaches, fever, confusion, and seizures. In severe cases, it can lead to permanent brain damage or be life-threatening.

Identifying and treating viral encephalitis early is crucial. Antiviral medications, alongside supportive care, can help manage the symptoms and reduce the severity of the inflammation.

meningitis

Meningitis is an infection of the protective membranes covering the brain and spinal cord, known as the meninges. Measles can lead to viral meningitis, although it is less common compared to other types caused by bacteria.

Symptoms of meningitis include sudden high fever, stiff neck, severe headaches, sensitivity to light, and sometimes confusion.

If you suspect meningitis, it is important to seek medical help right away. Hospitalization might be necessary for proper monitoring and treatment. This can prevent serious complications like brain damage or death.

infectious diseases

Infectious diseases are illnesses caused by microorganisms like viruses, bacteria, fungi, or parasites. Measles is a highly contagious viral infection that spreads through respiratory droplets.

Vaccination is a key method to prevent the spread of infectious diseases, including measles. Vaccines help the immune system recognize and fight off the pathogens effectively.

It is crucial to maintain good hygiene, such as regular hand washing and avoiding close contact with infected individuals, to limit the spread of infectious diseases. Early detection and treatment are necessary to control outbreaks and minimize complications.

symptoms of measles

Measles is characterized by a set of symptoms that start with mild to moderate fever, often accompanied by a cough, runny nose, and red, watery eyes. These initial symptoms appear around 10-12 days after exposure to the virus.

Following these early signs, a red rash starts, typically on the face and then spreading down the body. This rash can last for around a week. Additional symptoms might include white spots inside the mouth, known as Koplik spots.

Most people recover from measles within 7-10 days. However, complications can arise, particularly in young children, pregnant women, and individuals with weakened immune systems. Common complications include ear infections, diarrhea, and more severe illnesses like pneumonia and encephalitis.
