Answer 4

Rubella virus (Rubella)
HIV (AIDS)
Influenza virus (Flu) - mortality is common in high risk patients - feverish
Rhinovirus (cold - upper respiratory tract infection)- afebrile (not feverish)

Question 5

Fungal

Answer 5

Mycosis any disease induced by a fungus
Pneumocystis carinii/jirovecii (Fungal Pneumonia) Extremely serious form of pneumonia, causes significant mortality in IC and in healthy host

Yeast Candida Albicans
normally populates GI tract, mouth, genitals
Overgrowth causes candidiasis (genitals) or thrush (mouth)

Chlamydia (most common STI caused by bacteria, can infect fetus)
Herpes
Gonorrhea (pain during urination, can lead to cardiac valvular disease, arthritis, can infect fetus)
Hepatitis ( Hep B- DNA virus associated with liver cancer, infected blood, breast feeding, jaundice, arthralgias, rash, dark urine, clay-coloured stools, etc)
Syphilis (contact with skin and mucous membranes, transplacental, blood transfusions, Primary Syphilis has painless lesion (chancre) at the site of inoculation 3-8 weeks after infection, Secondary flu like symptom and rash, tertiary, severe cardiovascular and CNS disturbances

Answer 9

Leading cause of neonatal pneumonia, meningitis, septis, pregnant women are routinely screened

Question 10

Pneumococcal infections

Answer 10

streptococcus pneumonia
Often follows influenza, viral respiratory infections
Can cause pneumonia (fibrinous inflammation), sepsis (blood infection), otitis media (middle ear infection), meningitis (most common bacterial meningitis in adults, infants and toddlers)
Most common cause of community acquired pneumonia for young and old

Answer 12

members of the picornavirus family (small RNA virus)
aseptic meningitis, acute paralysis, hand, foot and mouth disease, myocarditis, mild respiratory illness, conjunctivitis, polio

Enters the mouth via fecal-oral route, multiples in tissues, reaches the CNS
Polio can cause poliomyelitis (polio), could develop post polio syndrome
