Introduction

Chronic infections with persistent pathogens such as helminths, mycobacteria, Plasmodium, and hepatitis viruses affect more than a third of

the human population

Worldwide influenza annual epidemics result in about 3-5 million cases of severe illness, and about 250 000 to

500 000 deaths.

In 2010, malaria caused an estimated 660 000 deaths (with an uncertainty range of 490 000 to 836 000)

In 2011, 8.7 million people fell ill with TB and 1.4 million died from TB.

There were approximately 35.3 million people living with HIV in 2012
