Malaria distribution and performance of malaria diagnostic methods in Malaysia (1980–2019): a systematic review
Abstract Background Malaysia has already achieved remarkable accomplishments in reaching zero indigenous human malaria cases in 2018. Prompt malaria diagnosis, surveillance and treatment played a key role in the country’s elimination success. Looking at the dynamics of malaria distribution during th...

More than half of all studies (28/46; 60.9%) were assessed by both microscopy and PCR.

The summary estimates of sensitivity were higher for P. knowlesi than other Plasmodium species for both microscopy and PCR.

Abstract Background Malaysia has already achieved remarkable accomplishments in reaching zero indigenous human malaria cases in 2018. Prompt malaria diagnosis, surveillance and treatment played a key role in the country’s elimination success.
