Crimean-Congo Hemorrhagic Fever (CCHF) in Pakistan: The “Bell” is Ringing Silently

Abstract

Pakistan is being hit by communicable and noncommunicable diseases over time. Among these, tickborne viral disease, Crimean-Congo hemorrhagic fever (CCHF) is one of the most fatal infections. Rapid climate change aroused by industrial, occupational, and agricultural activities to support ever-growing human population has been considered the single most causative basis for emergence or re-emergence of CCHF in Pakistan, where it has biannual peaks between the months of March–May and August–October. Many factors, including poor sanitation at farms, villages, and cities, unhygienic transportation and slaughter of animals at numerous sites within a city, inefficient tick-control programs, post-slaughter piles of animal remains other than meat, nomadic lifestyle, and lack of trained animal and human healthcare staff, are contributing to the spread of CCHF. Pakistan has confirmed cases of CCHF in almost every province: Sindh (Karachi), Punjab (Faisalabad, Multan, and Rawalpindi), Balochistan (Quetta) and Khyber Pakhtunkhwa (Peshawar). The root cause behind the spread of CCHF in Pakistan seems to be the absence of an effective disease surveillance system in the human as well as the animal populations. Most of the time, CCHF cases are not diagnosed, and if they are diagnosed they are not reported. If these cases are reported, there are not enough effective measures by the relevant provincial and district authorities. There is a need to educate the general public, farmers, and healthcare workers about the causes, transmission, and dangers of CCHF. An immediate plan for the implementation of a surveillance system, standard preventive measures, early detection, proper treatment, and timely response is urgently needed. Without such a plan, the accumulation of factors responsible for the sudden outbreak of CCHF may pose a serious threat to humans and animals in different geographical regions of the country.
