dermatropic disease

Identify the adenovirus structure

double stranded DNA with icosahedral virions, has a multitude of bodies composed of numerous virions in a crystalline stucture

what are symptoms associated with small pox

fluid filled pink and red spots that once opened lead to form pitted scars (pocks)

define syncytia

fusion of multiple host cells into single large cells containing multiple nuclei

describe the structure of mumps

helical RNA with envelope, rubeola

what virus causes herpes simplex, what is its structure

herpes simplex virus, icosahedral DNA with envelope

What is a frequent disease that developes later in life in patients who had chicken pox

how is chicken pox transmitted

highly contagious through respiratory droplets or skin contact

describe the structure of the rubella virus

icosahedral RNA with envelope

What part of the body to pneumotropic viral infections affect

lungs (respiratory illness)

what are the two symptoms associated with rubella

mild symptoms consisting of fever and rash

how many americans have developed herpes simplex before the age of 18

more than 90% develop the provirus in nerve cells, when stressed, the virus can reemerge

Describe an antigenic variation

mutation or a genetic shift

nerve damage

what are the symptoms of mumps when infected in parotid glands (salivary glands)

obstruction and swelling of the glands (cheek enlargement)

red rash on face (slapped cheek disease), most commonly affects children

how is rubella transmitted

respiratory droplets and contact

how is mumps transmitted

respiratory droplets, contact and fomites

What virus causes respiratory syncytial disease, identify the symptoms

respiratory sncytial virus, viral pneumonia and syncytia

what is a complication associated with chicken pox

reyes syndrome (liver and brain damage)

what is a complication that can arise from measels

secondary bacterial infections that damage respiratory and nervous system

describe the structure of respiratory synctial disease

single stranded RNA with envelope

the influenza virus

How is the influenza virus transmitted

through respiratory droplets

through respiratory droplets

define dermatropic viral diseases

usually infect the the skin of the patient

what virus causes the chicken pox virus, describe its structure

varicella, icosahedral double stranded DNA virus with envelop

How was smallpox eradicated

world wide vaccination by WHO along with isolation of infected individuals

is there a vaccination for chicken pox? what kind is it ?

yes, an attenuated strand of the virus is used

Who was the English Physician who treated smallpox, explain the story

Jenner, his milkmaid contracted cowpox, making her immune from smallpox, which led to the first vaccination of a boy
