Q Fever-A Neglected Zoonosis

Area of Science:

• Veterinary Medicine
• Infectious Diseases
• Zoonosis Research

Background:

• Q fever is a neglected zoonotic disease caused by Coxiella (C.) burnetii, posing a persistent infection risk to humans and animals due to the pathogen's environmental resistance.
• The infection is often asymptomatic in animals, leading to delayed diagnosis until adverse pregnancy outcomes occur, while chronic human cases can manifest as severe endocarditis and vascular infections.

Purpose of the Study:

• To highlight the need for further research into the molecular epidemiology and evolution of Coxiella (C.) burnetii in ruminants.
• To emphasize the importance of genomic studies for understanding outbreak relationships and molecular studies for exploring pathogen pathogenesis.
• To advocate for increased awareness and pasteurization of dairy milk to prevent Q fever transmission.

Main Methods:

• Review of existing data on Coxiella (C.) burnetii prevalence and impact.
• Discussion on the utility of genomic and molecular approaches for epidemiological and pathogenetic investigations.
• Analysis of prevention strategies including public awareness and milk pasteurization.

Main Results:

• Limited data currently exists on the molecular epidemiology and evolution of Coxiella (C.) burnetii, particularly in ruminant populations.
• Genomic studies are proposed as a key method for inferring outbreak connections and understanding disease spread.
• Molecular investigations are essential for elucidating the pathogenesis of Coxiella (C.) burnetii infections.

Conclusions:

• Genomic and molecular studies are vital for advancing our understanding of Q fever epidemiology and pathogenesis in Pakistan.
• Implementing awareness programs and ensuring dairy milk pasteurization are critical public health measures for preventing Q fever zoonosis.
