Filaria surveys in the Armed Forces: Need for a revisit.

BACKGROUND

Routine annual filarial surveys are conducted amongst various categories of military personnel and their families as per policies in vogue in the Armed Forces. The neglect and inattention faced by this disease needs to be addressed in terms of policy, provisioning and processes while dealing with filariasis in the Armed Forces.

METHODS

Routine annual filarial survey was conducted in a garrison during the months of Nov and Dec in 2013 and 2014. Blood slides from 6305 and 10,162 persons were collected in 2013 and 2014 respectively. 546 (60.66%) civilian migratory labourers were also subjected to the filarial survey.

RESULTS

Of the blood slides collected amongst service personnel, 41 were positive for mf in 2013 and 29 in 2014 (i.e. a slide positivity rate (SPR) of 0.65% and 0.28% respectively). Out of 546 blood slides of the migratory population, 10 were found mf positive (SPR 1.83%) and three males had lymphedema.

CONCLUSION

It is recommended that routine annual filarial survey conducted in military garrisons should include all personnel belonging to known endemic states. Newer modalities of detection of infection may be considered to replace night blood surveys. An organization-specific surveillance programme on prevention and control of Lymphatic filariasis in the Armed Forces thus may need to be launched so that we can achieve elimination.
