Of course, my paranoia is mostly unwarranted because i have never heard of anyone getting malaria from roobios, nonetheless, i think i can live without it.
For malaria, the equation looks like this:
+ Anopheles mosquito
I totally get your caution, PeterVu
(which is why I wear water wings in the shower) -- but your chances of getting malaria of any kind from brewed or unbrewed tea are 0%. You need a mosquito infected with P. falciparum
(which causes something like 88% of all malaria cases), P. vivax, P. ovale, P. malariae, P. knowesli,
or P. semiovale
to bite you.
Want to learn more about parasites? Do you also have a cast-iron stomach? Then I highly suggest Parasite Rex
. But don't eat it before eating pad thai. Seriously.
(Alternately, you can look for me in the Invertebrate House of the National Zoo where I volunteer on weekends. We can talk parasites and then I'll let you feed an anemone.)
