5/1: Viruses
Ebola & Marburg
❖ Marburg first in 1967 during small outbreaks in German cities
o Workers exposed to tissues of infected grivet monkeys at the industrial plant of
the city
❖ Marburg
o Central/western Africa
o Marburg, Germany
❖ Spreads – small communities, lack of sanitation/healthcare opportunities
❖ Whenever there are huge epidemics in urban areas, large number of people become
incredibly ill and cause secondary problems (hemorrhagic fever, dengue, EEE, influenza
outbreak, etc.) – large portion of population becoming ill at one time = secondary
problems
o Health care systems itself get infected and shut down – other patients with
treatable diseases die because of this
o Ebola outbreak happens because of poor health care infrastructure; not because
it is so fatal
❖ Health/productivity of developing outries is’t just good for the, ut good for the
global community because of global connectivity. Improving infrastructure in developing
countries will help reduce these infectious disease epidemics
❖ Ebola effets ay thigs…
o Economy – a’t work, harvest is delayed (no agriculture/planting food
shortages), poor/no sanitation, etc.
o Solutions – help them to help the global economy and health
Hantavirus – New world
❖ New world = pulmonary (respiratory) syndrome; old world = hemorrhagic fever w/ renal
syndrome (effects liver)
❖ Cardio-pulmonary infection, fever, respiratory distress, followed by shock, muscle pains,
abdominal problems (nausea, vomiting, pain), cough, shortness of breath, lungs fill with
fluid (what kills you), etc.
❖ Each virus subtype has its own rodent host (i.e., deer mouse)
❖ 30 identified subtypes, of which 14 known to cause disease
❖ South and North America; predominantly west of Mississippi river (dryer regions) – first
identified in 1993
❖ Mechanical transfer – urine, saliva, or feces
❖ Virus is shed in bodily fluids of rodents onto objects – when they dry they can be
swept/blown into air inhaled transmitted to humans
o Another type of transmission (rare) – bite
o Not transmitted human to human
❖ Cleaning mouse pellets/nests/cages may lead to hantavirus
❖ Most at risk – campers, construction workers, hikers, farmers, etc.
