The Dolphins' regular-season home opener isn't until September 25, but they will host the Titans in the final preseason contest on September 1. And the organization is keeping an eye on two possible looming threats: A tropical wave that has a 70 percent chance of developing into a storm in the next five days, and the Zika virus.

Miami Beach has been designated a Zika hot zone, and Miami Gardens, where the Dolphins play in the newly named Hard Rock Stadium, is just 15 miles away. As a precaution, officials have been treating the 265-acre property around the stadium -- including the parking lots -- all month, according to the Palm Beach Post's Joe Schad.

More details:

The Dolphins are contracted with a pest control company that has followed CDC (Center for Disease Control) recommendations in its multi-step approach and are using products deemed safe for people, pets and aquatic life.

The Dolphins have treated drainage areas, standing water, retention areas and other areas where it is determined mosquitos may harbor. The treatments include the use of backpack foggers every two weeks and will include treatments two days before events such as Miami Dolphins or University of Miami football games.

Only 43 United States residents have contracted the Zika virus, and all but one of the cases was in South Florida.
