Study Notes
Measles Virus
- The measles virus belongs to the genus Morbillivirus.
- Measles is primarily transmitted through respiratory droplets, such as through coughing and sneezing.
- Before widespread vaccination, measles caused approximately 2.6 million deaths annually in 1980.
- The measles virus has a single-stranded RNA genetic material.
- The measles virus normally grows in epithelial cells and macrophages.
Mumps Infection
- The most common symptom of a mumps infection is swelling of the parotid glands.
- Symptoms of mumps typically occur 16-18 days after exposure to the virus.
- A rare complication of mumps is orchitis, which may result in reduced fertility in males.
- The mumps virus is primarily transmitted through direct contact with respiratory droplets, such as through touching or sharing utensils.
- Approximately 30-40% of mumps infections are asymptomatic.
