A clinico-epidemiological study of filariasis was carried out in Varanasi District in October and November, 1997 to generate baseline data for assessing the impact of Mass Drug Administration (MDA) in the district. Disease rate was found to be 6.6% (9.9% in males and 3.0% in females) and microfilaria rate was 5.3% (5.2% in males and 5.5% in females). Mean microfilaria density was found to be 9.86 per 20 Cu.mm blood. Genital manifestations (77.5%) outnumbered all other forms of clinical manifestations. Vector infectivity rate was found to be 0.93%.

Onchocerciasis is not a major cause of blindness in two endemic villages in Sierra Leone.

Helen Keller International, New York, USA.
Objective: Sierra Leone, a country where onchocerciasis is endemic in 14 of the 16 districts, was the focus of our investigation. Despite 17 rounds of annual ivermectin treatment since 2005, a report circulated by a local politician indicated an increase in cases of suspected onchocerciasis-related vision impairment in two villages (Mangobo and Petifu) in Tonkolili district. In response, the National Neglected Tropical Disease Program conducted a comprehensive investigation.

Background: Lymphatic filariasis (LF), a mosquito-borne parasitic disease caused by three species of filarial worms, was first detected in Niue, a small Pacific Island nation of approximately 1,600 people, in 1954. After extensive efforts involving multiple rounds of Mass Drug Administration, Niue was validated by the World Health Organization (WHO) as having e4liminated LF as a public health problem in 2016. However, no surveillance has been conducted since validation to confirm infection rates have remained below WHO's elimination threshold.

A 12 yr old female spayed American Staffordshire terrier was referred for stranguria, pollakiuria, and concern for a mass in the trigone of the urinary bladder. A urinalysis and abdominal ultrasound were performed to further investigate the bladder mass. Nematode larvae were identified in the urine, termed microfilaruria, while a caudal abdominal mass was found on ultrasound impinging on the urethra.

We report an interesting case of Bancroftian filariasis diagnosed on fine needle aspiration cytology in a young female hailing from a non-endemic hilly area of India, who presented with a subcutaneous swelling on the left forearm. This is an unusual extra-lymphatic site to harbor filarial infestation and the cytology smears showed adult worms, eggs, and microfilariae of .

Background/methodology: Despite progress using mass drug administration (MDA), lymphatic filariasis (LF) remains a major public health issue in India. Vector control could potentially augment MDA towards LF elimination. We conducted a cost-effectiveness analysis of MDA alone and MDA together with vector control single (VCS) modality or vector control integrated (VCI) modalities.
