Leptospira is a spirochaete. It usually spreads from rodents to man. They are excreted in urine. Transmission to man may follow direct contact with urine, blood or tissue from an infected animal or exposure to a contaminated environment. Therefore, epidemic may result from exposure to flood water contaminated by urine from infected animals. The spirochaete may enter through skin abrasions or even through intact mucus membranes of mouth, oropharynx or oesophagus on swallowing.

Bilharziasis is the older name of Schistosomiasis. Portal of entry into man

is through skin, when wading or swimming in water infested with cercariae larvae

So, the correct answer is 'Leptospirosis and bilharzia'
