**Explanation:**

Elephantiasis disease, also known as lymphatic filariasis, is a parasitic infection caused by microscopic worms. It is transmitted through the bite of infected mosquitoes. The disease primarily affects the lymphatic system, which is responsible for maintaining fluid balance and fighting infections in the body.

The correct answer to the question is option **C) long term affect on our health**. Elephantiasis disease can have significant long-term effects on a person's health. Here's why:

1. **Lymphatic System Damage:** The parasite responsible for elephantiasis primarily affects the lymphatic system. Over time, the worms can cause inflammation and damage to the lymphatic vessels, leading to impaired lymphatic drainage. This can result in the accumulation of fluid in the affected areas, causing swelling and enlargement. In severe cases, this can lead to the development of elephantiasis, characterized by extreme swelling and thickening of the skin.

2. **Chronic Inflammation:** The presence of the parasite in the body triggers a chronic inflammatory response. Prolonged inflammation can lead to tissue damage and scarring, further contributing to the progression of the disease. This chronic inflammation can also affect other organs and systems in the body, causing additional health complications.

3. **Secondary Infections:** The compromised lymphatic system in individuals with elephantiasis makes them more susceptible to secondary bacterial and fungal infections. These infections can further worsen the symptoms and lead to recurrent episodes of inflammation and swelling. They can also cause additional health problems and increase the risk of complications.

4. **Physical and Psychological Impact:** Elephantiasis can have a significant impact on a person's physical and psychological well-being. The visible deformities and disfigurement associated with the disease can lead to social stigma, isolation, and psychological distress. The physical limitations caused by the swelling and mobility impairment can also affect a person's quality of life and ability to perform daily activities.

5. **Economic Burden:** Elephantiasis can have a long-term economic impact on individuals and communities. The chronic nature of the disease and the associated disabilities can result in reduced productivity, loss of income, and increased healthcare costs. This can further perpetuate the cycle of poverty and hinder socio-economic development in affected regions.

In conclusion, elephantiasis disease can have long-term effects on a person's health, including damage to the lymphatic system, chronic inflammation, secondary infections, physical and psychological impact, and economic burden. Early diagnosis, prompt treatment, and preventive measures such as mosquito control and mass drug administration programs are crucial in reducing the prevalence and impact of this disease.
