taxi fare, mosquitoes

2nd. Is mosquito repellent necessary? I've been hearing about dengue fever?! however I am a long time visitor to Zihua (40 plus years) and have never had a problem with bites...the hotel sprays regularly and the bats on their rounds at dusk seem to help. but of course the climate has changed so if anyone has advice your input is appreciated.

Well, we are in the tropics. Dengue is a virus spread by mosquitoes. Many in Zihua have been infected.

There is no vaccine for dengue. Symptoms can be treated but there is no cure. Some people recover quickly. Some people die.

Spraying a bit of mosquito repellent on oneself seems to be a small inconvenience compared to being infected with the dengue virus.
