North Atlantic right whales (Eubalaena glacialis) are big, but they're not the biggest whales. That distinction goes to the blue whale (Balaenoptera musculus), the largest animal on Earth. The orca's size of up to 31 feet (9.4 meters) makes it the largest dolphin. The sperm whale, on the other hand, may not be the biggest whale, but it has the biggest brain to have ever existed on Earth. A comparison chart of whale sizes helps put it all in perspective!
Chikungunya fever is caused by a virus that is spread to people through the bite of infected mosquitoes. Like Dengue, it is transmitted by Aedes mosquitoes, especially Aedes aegypti (the yellow fever mosquito) and Aedes albopictus (the Asian tiger mosquito).
Still, public health officials believe the arrival of the Aedes aegypti mosquito is cause for worry. In 2009, cases of dengue fever, along with the mosquito that carries it, began appearing in Florida.Yellow fever ranges in severity, from a mild self-limiting fever to a deadly hemorrhagic fever that results in liver disease and bleeding.either fever has a specific treatment, but people who suspect they are infected by either virus should go to the hospital for supportive treatment. County health departments in the state are monitoring for cases of these diseases, urging local agencies to set up mosquito traps to facilitate the process.
