Insecticide-treated mosquito nets (ITNs) have been a cornerstone of malaria prevention efforts for decades. ITNs have demonstrably reduced malaria morbidity and mortality.

Half of the ITNs are less than 2 months old, indicating a recent distribution campaign. The reported ITNs used the night before the survey was 73 %. Over half of the households (52 %) reported losing at least one ITN in the past year, with an average of 2.53 nets lost per household. The most common ITN brand contains alpha-cypermethrin and chlorfenapyr insecticides.

Further research is needed to quantify the environmental impact of abandoned nets. ITNs distribution programs should be complemented by collection and potential recycling initiatives.

This study aimed to investigate the silent carriage of ESBL-producing <em>Escherichia coli</em> (ESBLEC) and <em>Klebsiella pneumoniae</em> (ESBLKP) among economic migrants from Indonesia, Bangladesh and Nepal residing in Klang Valley, Malaysia. Between December 2023 and May 2024, 263 study participants of Indonesian, Bangladeshi, and Nepalese migrant communities were recruited and rectal swabs collected. Swabs were then cultured on CHROMagar™ ESBL; presumptive ESBL-positive strains were confirmed and antimicrobial susceptibility-tested using a VITEK 2 system. ESBL genotyping was also performed on confirmed isolates. A total of 67 and five strains were confirmed as ESBLEC and ESBLKP, respectively. Both ESBLEC and ESBLKP strains showed similar resistance to penicillin and 3rd generation cephalosporins, though more ESBLKP strains were resistant to 4th generation cephalosporins. More ESBLEC strains were resistant to ciprofloxacin. No carbapenem-resistant strains were detected.
