Since 2012, government healthcare facilities alone have recorded 913 confirmed cases of scrub typhus, with 34 deaths.
According to the UNI report, the entomologist has further warned that the actual number of cases could be nearly double if private healthcare facility data were included.
The first cases of scrub typhus were identified in Mizoram during the gregarious flowering of the 'Mautak' (Melocanna baccifera) bamboo species between 2006 and 2008, which led to a dramatic increase in the rodent population.

Rodents, particularly rats, are the primary carriers of the disease, which is caused by the bacteria Orientia tsutsugamushi. The disease is transmitted to humans through the bites of trombiculid mites, which feed on infected rats.
While scrub typhus was initially confined to rural areas, the situation has changed significantly. Recent reports indicate that 30.09% of all scrub typhus cases now come from urban areas, specifically 41 localities within the Aizawl Municipal Corporation (AMC), reports UNI.
The entomologist emphasized that, in addition to malaria, scrub typhus has now emerged as a major public health threat in Mizoram.
The outbreak has led to increased concerns about the role of rodents in the spread of the disease. In response, the faculty members of the Zoology Department at Pachhunga University College issued a public warning on Wednesday, urging people to avoid direct contact with rats, both dead and alive.
This follows a recent spike in rodent population linked to the flowering of the ‘Rawthing’ (Bambusa tulda) bamboo species this year, which has once again triggered a surge in the rodent numbers.
The experts specifically cautioned that touching live or dead rodents could result in scrub typhus infection, which remains highly contagious.
