He gave a history of having a recent photography session in Bandipur National Park . On examination you observe the following : BP – 140/70 mmHg Temp - 101°F

3. What is the disease and identify the causative agent. Enumerate viruses causing VHF. Comment on it epidemiology in India, past and present. Explain the ecology of the causative organism and comment on the pathogenesis. Laboratory diagnosis of the disease.

4. 2. (121-140) A 44 year old woman, working in an international NGO, presented to the OPD with fever, severe joint pains and headache. She has a history of travel to an African nation recently, where people were suffering from similar illness. The locals there used the word “ kungunyala ” to describe the condition of the illness. On further history, fever was acute, and present since 4 days. The following rash over the nose was observed, which appeared 2-3 days after onset of fever:

5. What is the disease, and the causative organism. Discuss the disease under the following headings: Host, Vector, mode of transmission Comment on its epidemiology in India Explain the clinical features. Laboratory diagnosis. Discuss NVBDCP related to this disease.

6. 3. (141-160) Sunita, a 29-year-old female from Delhi came to casualty with complaints of high-grade fever, severe joint pain, back pain and myalgia . Gradually, she developed petechial rashes over the body. On examination, she was found to have jaundice, hepatomegaly and a low platelet count (30,000/ ).
