2. Filariasis Introduction :- Infection caused by three closely related nematodes (W. bancrofti , B. malayi & B. timori ) & transmitted to man by bite of infective mosquitos & clinically characterized by- ►Lymphangitis, lymphadenitis, elephantiasis of genitals, legs & arms or ► Pulmonary esonophilia or ►Filaria arthritis. Epidemiological determinants Agent factors- ➡ Definitive host – Man ➡ Intermediate host- Mosquito ➡ Agents of lymphatic filariasis- W. bancrofti , B. malayi & B. timori . ➡ Agents of non-lymphatic filariasis- Onchocerca volvulus, Loa Loa .

3. Reservoir of Infection :- ■ Man with circulating microfilaria . ■ For Brugia - Monkeys, cats, dogs . Life cycle

4. Host factors :- ■ Age:-Affect all ages, Infection rate more in 20-30 years. ■ Sex:-Male > Female. ■ Migration- spreads infection. ■ Immunity- After many years of exposures. Vectors of lymphatic filariasisVectors :- ✓ Culex, Anopheles & Aedes for W. Bancrofti . ✓ Mansonia , Anopheles for Brugia species. Incubation Period :- Clinical incubation period- ✓ 8 to 16 months

5. Mode of transmission :- Bite of infected mosquito vector:- Parasites deposited at puncture site. Passes through puncture skin or may penetrate skin & finally reach lymphatic system. Dynamics depends upon man-mosquito contact (infective biting rate. Clinical manifestations :- 1. Asymptomatic amicrofilaraemia . 2. Asymptomatic microfilaraemia . 3.Stage of acute manifestations. 4.Stage of chronic obstructive lessions .

6. Lab Diagnosis :- A Thick Blood Film – Mf + Membrane filter concentration [MFC]. DEC Provocation Test. Prevention And Control :- Vector Control:-Mosquito Control Chemptherapy :-Tab.DEC-6mg/kg Daily Orally for 12 days in divided doses. -Tab.IVERMECTIN-20-400 μ g/kg in single dose.
