Happy New Year to you !
I can only remember seeing one snake in the 10 years I lived in Aden. That ended up in a specimen jar for the school's biology class. On my first trip to Aden in 2006 I was advised by the local travel doctor to be vacinnated against typhoid and yellow fever. He also gave me anti malaria tablets and cipro. I took the malaria tablets. Talking to the locals there has not been any outbreaks of malaria in the Aden for years. On the other trips I didn't bother with any medications with the exception of some sticking plasters and Savlon. Good fun eh.
Happy New Year!
I would strongly advise Typhoid vaccination as I do remember outbreaks of this when I lived in Aden. These outbreaks were mainly in schools in Big Aden but one time The Rex Italian restaurant in the crescent was closed for Typhoid & my family & I had eaten in there the day before. Typhoid does tend to be waterborne
& people can be carriers so if this is the only vaccination you have it would be well worth it.
As for snakes I was nearly bitten on 2 occasions in our garden in Ghadir. The Yemeni scorpions can give a fatal sting too, no need for hysteria just be vigilant
