[Stoves] The other side of airpollution

[Crispin Pemberton-Pigott]

Dear Dr Martin

I agree with you on this.  Lowering smoke pollution in houses it likely to 
have an effect on the disease profile because disease transmitting insects 
will have a much easier time of it when the smoke and CO are removed.

Cecil Cook reports that in order to control mosquitoes in Brazil (living 
with the Nambiquara Indians) they use to make a smokey fire that went all 
night, and lowered the already low doorway with a cloth to keep the smoke 
about 25mm above their noses.  This killed the mosquitoes and kept them away 
from the people, leaving a small gap of clean air below the level of the 
door flap.

It is perhaps one reason why the entrances of houses made of grass have a 
low entrance.  Clean stoves probably reduce severe pneumonia and increase 
malaria unless further measures are taken.
