Virology 1.B Flashcards
What is the Fever range of a virus compared to a bacterial infection
Viruses typically have a low grade fever (~99.6°F to 100.3), while bacteria tend to have a high grade fever (100.4°F)

Progression difference between viral infection and bacterial infection?
Viruses tend to have unchanging symptoms over a long period of time from onset moving forwards. It is much more casual ( some sniffles and a cough for 5 days, no changes in severity).
Bacteria tends to make rapid symptom onset with slight cough one morning, then high grade fever the next, followed by more symptoms. It is much more acute in a shorter period of time.

Infection Fluid consistency between viruses and bacteria?
Fluid tends to be less changing with viruses, unchanging appearance of discharge, urine, etc.
Bacteria tends to result in fluid/discharge that is thick and cloudy d/t bacterial cells being much thicker and larger than viral cells = less refraction through the fluid.

Name three common viral rashes?
Mononucleosis (Mono, kissing disease), Chickenpox (Varicella), and Shingles (VZV)
If the rashes is unknown in origin and not associated with other bacterial symptoms, it is likely a viral rash.
Virus vs Bacteria inflammatory cells
Virus = MONOCYTES Bacteria = NEUTROPHILS
KNOW THIS.
What is an endemic?
A disease outbreak is endemic when it is consistently present but limited to a particular region. For example, Malaria
What is an epidemic?
an epidemic as an unexpected increase in the number of disease cases in a specific geographical area. Yellow fever, smallpox, measles, and polio are prime examples of epidemics.
It begins as an endemic that surpasses a calculated threshold into “unprecedented” values.
What is a pandemic?
A global epidemic.
Not all epidemics are pandemics, but all pandemics are epidemics.
What is a Syndemic and give an example.
A Syndemic or synergistic epidemic is the aggregation of two or more concurrent or sequential epidemics or disease clusters in a population with biological interactions, which exacerbate the prognosis and burden of disease.
The interaction between HIV and tuberculosis. While one is caused by a bacteria and the other a virus, having one of these diseases makes a person much more susceptible to the other.
What is an outbreak?
A sudden rise in the number of cases of a disease.
However this is somewhat relative to their threshold, for example 5 cases of the flu in a college dorm at UW is not an outbreak. 5 cases of Ebola in a college dorm at UW is scary as fuck.
What are Carriers, Subclincally infected, and Latently infected?
Subclincal infections are which infected persons may or may not show signs of sx’s (Asymptomatic) therefore escapes clinical dx. They also very well could be Presymptomatic
A Carrier (colonized individual) is a person in whom organisms are present and may be multiplying, but who shows no clinical response to their presence.
Latently infected is a person who was previous experiencing symptoms and has the virus dormant.
