    Dear TWIP hosts,
    Having missed the cut-off for the last episode I am getting my guess in on TWIP 179 immediate I heard the episode.
    Headache, fever, and muscle aches are all classic malaria signs, as is enlarged spleen. The cdc website (see below) notes a number of malaria species are endemic and recommends atovaquone-proguanil, doxycycline, mefloquine, or tafenoquine. Young children are also most at risk as they haven’t built up an immune defence and her mother’s antibodies would have run out, so it is probable she has had chronic malaria. The reason for the initial negative smear could be a false negative or the body has cleared the parasite but the impact of chronic exposure is still being felt. Other parasites such as VL may caused some of the symptoms but are less likely (when in Africa hoofbeats suggests zebras not horses…)
