Document Summary
Blood & tissue protozoa: plasmodium, malaria, toxoplasma gondii, toxoplasmosis, trypanosoma, two diseases depending if you are in south america or africa. Malaria: 2nd to aids causing mortality, risk in > 100 countries, ~240 million cases annually, marked increase in drug resistance. No consent for blood taking: only females bite, attracted by body heat then the co2 we exhale, which puts them in biting mode. Joggers much easier to find: fill our blood through our bp, barf saliva to keep blood flowing contains sporozoa that causes malaria and antigens that irritate us, night biting mosquitos contain malaria. Any patient with a fever who has recently returned from the tropics has malaria until proved otherwise. Plasmodium falciparum: giemsa stain, blood filled stain, heavy infestation of delicate ring forms. Prevention of malaria: personal protective measures: repellent, bed net, screened or air-conditioned quarters dusk to dawn, antimalarial drugs. Toxoplasma gondii: most human infections are benign, asymptomatic or infectious mono, occasionally myocarditis.
