  1. My question is: Since this disease can be blood borne, and sexually transmitted, it sounds very similar to AIDS. In your opinion, if Zika, can be transmitted this way, do you think Aids can as well? I would think this fact would be hidden, as not to cause a worldwide panic. Your thoughts?

      1. In the place where there had been three floods in 22 months nothing was done by govt. For three years I lived in another area that had the potential for mosquito plagues, the local council would do routine spraying.

      2. It’s the govt responsibility to take adequate measure in order to eradicate these highly contagious diseases. Regular Pest Control, Proper Sewage maintainence etc ample of budget is being wasted on other sectors in india medical budget comprises of just 0.3% in central and 3.4% in state. Govt should raise medical budget then only proper health programming will maintain

      3. Its an ongoing battle with the govt here in Australia getting funding , they don’t seem to prioritze very well if at all. A lot of money gets wasted on uncessary items.

      4. Yes you are correct same goes here also govt still hasn’t been able to raise medical budget despite lots n lots of petitions, efforts,strike etc
