Will malaria suppression cause malnutrition?

The great benefit in saving so many children by suppressing malaria, might have a negative consequence - malnutrition. As more and more children survive, who will feed them? This reflects the classic dilemna enunciated by the Rev. Malthus some centuries ago. He saw it as a race between population growth and growth in food supply - with the food supply losing. Do we face that same dilemma when we suppress malaria? Let us look at some recent data from Africa.

Malaria suppression improves economic productivity

June 6, 2016 - 11:32 -- William Jobin

In a recent Comment - Does malaria cause poverty or vice-versa? Patrick Sampao explored the relation between malaria and poverty. In accord with his opinions, and in agreement with our dear friend Anton Alexander, I posted three comments, based on statistical analyses of the impact of the US Presidential Malaria Initiative. The comments show us some really Good News about suppressing malaria, especially in Africa where the data is robust. Please take a look at the comments. It is kind of heavy reading but I assure you, it is worthwhile.

Desiccation tolerance in Anopheles coluzzii: the effects of spiracle size and cuticular hydrocarbons

The assay's relative humidity, body water available, rate of water loss, and water content at death accounted for 88% of the variation in desiccation tolerance. Spiracle size did not affect the rate of water loss or desiccation tolerance of the colony mosquitoes, as was the case for the total CHCs.
