  • Delhi’s malaria (431) and chikungunya (75) totals through Oct. 4 are the highest in five years, dengue cases have risen to 840, and MCD staff strikes plus large numbers of untraced cases are hampering targeted response.

  • Pakistan’s Punjab province reports fresh daily increases, including 22 new cases in Rawalpindi and a provincial tally of 1,557, as Lahore hospitals face crowding, inactive dengue counters, and intermittent test‑kit supplies.
