|
Influenza type A |
acute, highly contagious respiratory illness, seasonal, pandemics, among top 10 causes of death is US |
|
|
Paramyxoviruses |
enveloped ssRNA, parainfluenza, mumps virus, measeles virus, respiratory syncytia virus, respiratory transmission |
|
|
Parainfluenza |
as widespread as influenza but more benign, respiratory transmission, seen mostly in children, minor cold, bronchitis, bronchopneumonia, croup |
|
|
Mumps |
epidemic parotitis, self-limited, associated with painful swelling of parotid salivary glands, humans are the only reservior |
|
|
Measles |
caused by Morbillivirus, also known as red measles & rubeola, very contagious, transmitted by respiratory aerosols, virus invades respiratory tract |
|
|
RSV respiratory syncytial virus |
also called Pneumonvirus, infects upper respiratory tract & produces giant multinucleate cells, most prevalent cause of respiratory infection in children 6 months or younger, epithelia of nose & eye portal of entry |
|
|
Rabies |
bullet-shaped virions, enveloped, slow, progressive zoonotic disease, virus enters through bite, grows at trauma site for a week, enters nerve endings & advances toward the ganglia, spinal cord & brain |
|
|
Coronavirus |
relatively large RNA viruses with distinctively spaced spikes on their envelopes, common in domesticated animals Severe Acute Respiratory Syndrome (SARS) |
|
|
Rubella |
caused by Rubivirus, a Togavirus, German measles, transmitted thorugh contact with respiratory secretions, attenuated viral vaccine MMR |
|
|
Arboviruses |
viruses that spread by arthropod vectors- mosquitoes, ticks, flies, & gnats, more than 400 viruses spread this way examples: dengue fever, western-& eastern equine encephalitis, yellow fever |
|
|
Dengue |
"breakbone" fever, severe pain in muscles and joints |
|
|
Yellow Fever |
fever, headache, muscle pain, may progress to organ failure and death. Mosquito control has greatly decreases its impact |
|
|
West Nile Fever |
Energing concern in US symptoms include fever, headache, tiredness, and body aches, occasionally with a skin rash and swollen lymph glands |
|
|
Hepatitis A |
causes short-term hepatitis, fecal-oral transmission, inactivated viral vaccine (HAVRAX) |
|
|
Rhinovirus |
110 serotypes, cause the common cold |
|
|
Poliovirus |
pretty tough virus: resistnace to acid, bile & detergents, survives stomach acids, virus is ingested, most infections are mild, grows in oropharynx & intestine, then enters blood (viremia) |
|
|
Reoviruses |
nonenveloped, segments dsRNA viruses, not a significant human pathogen, may cause upper respiratory disease similar to common cold |
|
|
Ebola virus |
a virus-caused disease limited to parts of Africa. Within a week, a raised rash, often bleeding, spread over the body. Bleeding from the mucous membranes is typical causing bleeding from the mouth, nose, eyes, and rectum |
|
|
Hanta virus |
The virus is spread by human contact with rodent waste. Dangerous respiratory illness develops.Effective treatment is not yet available and over 50% of cases end in fatality |
|
|
Retroviruses |
enveloped, ssRNA viruses, encode reverse transcriptase enzyme which makes a DNA cop of their RNA genome |
