USC researchers develop new portable device for early-stage malaria detection

According to the World Health Organization, over 216 million people were infected with malaria in 2016, and 445,000 individuals died from the disease. The key to solving this health crisis is early-stage diagnosis when malaria therapeutics are most effective. A new prototype for a portable instrument capable early-stage malaria detection has been developed by a team of researchers at the USC Viterbi School of Engineering.
