17
Q

What type of disease does Antigenic Drift cause and why?

A

Milder infection because the previous antibodies still partially recognize the modified Hemagluttinin and Neuraminidase

18
Q

Antigenic Shift

A

Trading of RNA segments between viruses resulting in completely NEW hemagluttinin and Neuraminidase

19
Q

What type of disease does Antigenic Shift cause and why?

A

Everyone is susceptible because it creates completely new virulence factors

20
Q

MMR vaccine protects against?

A

Measles
Mumps
Rubella

21
Q

Cascade of symptoms of Measles infection?

A
  • Fever and cough
  • Koplik’s spots
  • Head to toe maculopapular rash
    • Possible pneumonia
22
Q

Koplik’s spots?

A

Oral lesions that are white and red on the periphery

- seen with Measles

23
Q

Main symptoms of Measles?

A
  • Koplik’s spots (white oral lesions with red periphery)

- Head to toe maculopapular rash

24
Q

What is Subacute Sclerosing Panencephalitis?

A

Progressive neurologic disease
= forgetfullness, hallucinations and distractibility
– later symptom of measles infection

25
Q

When will those with measles develop subacute sclerosing panencephalitis?

A

Months to years after the initial infection

26
Q

Rubella symptoms are very similar to?

A

Measles
