Filariasis often present

Introduction to filariasis Filariasis perstans is a parasitic disease caused by the frequent occurrence of silkworm parasites in the body cavity (thoracic cavity, abdominal cavity and pericardium), mesentery, perirenal or retroperitoneal tissue. basic knowledge The proportion of illness: 0.043% Susceptible people: no specific people Mode of transmission: parasitic spread Complications: arthritis, pericarditis, heart failure

Common cause of filariasis

(1) Causes of the disease

The female is long, wide (70-80) mm × 120 m, male long, 45 mm × 60 m wide, microfilament length, width 200 m × 4 m, no sheath, irregular periodicity.

(two) pathogenesis

The pathogenesis is similar to that of Roa filariasis.

Filariasis prevention

1. The census of the early detection of patients and worms, timely cure, not only to ensure the health of the people, but also reduce and eliminate the source of infection. The census shall target all residents over one year of age and require more than 95% of the residents to accept blood collection;

2. Anti-mosquito and mosquito killing;

3. Strengthen epidemiological surveillance of areas where basic filariasis indicators have been eliminated. In the monitoring work, it should be noted that: 1 review and re-examine the original positive patients; re-investigate and repair the unexamined patients; strengthen the management of the floating population, find the patients, and treat them in time until they turn negative. 2 Strengthen the mosquito-borne surveillance of blood-positive households and find that infected mosquitoes, that is, focus on infected mosquitoes, expand blood tests and kill mosquitoes to surrounding people to remove epidemic spots and prevent further spread.

Common filariasis complications Complications arthritis pericarditis heart failure

Can be complicated by arthritis, pericarditis, severe heart failure.

Common filariasis symptoms Common symptoms Hepatosplenomegaly eosinophilic heart failure pericarditis

Filariasis can be long-term parasitism without symptoms, but in some cases there may be a variety of clinical symptoms, including angioedema, similar to Roa's carafe, headache, joint pain, neuropsychiatric symptoms, liver Splenomegaly, eosinophilia, etc., severe cases may occur with pericarditis, and even heart failure.

Common filariasis check

Peripheral blood eosinophilia, blood can find microfilaria.

Diagnosis and identification of filariasis

Diagnosis depends on finding microfilaria in the blood.

It should be differentiated from onchocerciasis and filariasis.
