Georgia Coastal Health District

Chatham County Mosquito Control has confirmed that samples of mosquitoes collected in the midtown Savannah area have tested positive for West Nile virus (WNV). Mosquito control personnel routinely collect and sample mosquitoes in all areas of Chatham County. This is the first positive WNV test in the Chatham County mosquito population this year. No human cases of WNV have been confirmed this year in any Coastal Health District counties, including Chatham.

WNV is transmitted to humans by the bite of infected mosquitoes and can cause mild to serious illness. “Most people who become infected won’t even show symptoms, but about 1 in 5 may develop a fever, headache, body aches, joint pains, vomiting, diarrhea, or rash,” said Dr. Lawton Davis, Health Director of the Coastal Health District. “A small number of people may become seriously ill and could die from West Nile virus.”

The Coastal Health District is encouraging all residents to take extra precautions now that WNV is actively circulating in the local mosquito population. “There are simple things we can all do to protect ourselves from mosquito bites and discourage mosquito breeding around our homes and yards,” said Dr. Davis.

One of the most effective ways to keep mosquitoes from your yard is by eliminating standing water, which mosquitoes need for breeding. Residents are urged to “Tip ‘n Toss.” After every rainfall, tip out water in flowerpots, planters, children’s toys, wading pools, buckets, and anything else that may be holding water. If it holds water and you don’t need it (old tires, bottles, cans), toss it out. It’s also a good idea to change water frequently in outdoor pet dishes, change bird bath water at least twice a week, and avoid using saucers under outdoor potted plants.

For containers without lids or that are too big to Tip ‘n Toss (garden pools, etc.), use larvicides such as Mosquito Dunks© or Mosquito Torpedoes© and follow the label instructions. These larvicides will not hurt birds or animals. In addition, clean out gutters, remove piles of leaves, and keep vegetation cut low to prevent landing sites for adult mosquitoes. Homeowners associations and neighborhoods, along with city and county governments, are encouraged to sponsor community cleanup days.

Chatham County Mosquito Control is actively treating all areas of Chatham County for mosquitoes. Residents should expect to see Mosquito Control’s low flying, yellow helicopters on a regular basis throughout the county.

Personal protection is also important, and residents are always encouraged to follow the 5 Ds of mosquito bite prevention:

Dusk/Dawn – Mosquitoes usually bite at dusk and dawn, so avoid or limit outdoor activity at these times.

Dress – Wear loose-fitting, long sleeved shirts and pants to reduce the amount of exposed skin.

DEET – Cover exposed skin with an insect repellent containing DEET, which is the most effective repellent against mosquito bites.

Drain – Empty any containers holding standing water because they are excellent breeding grounds for virus-carrying mosquitoes.

Doors – Make sure doors and windows are in good repair and fit tightly, and fix torn or damaged screens to keep mosquitoes out of the house.

UPDATE:

On June 26, 2019, the Chatham County Health Department lifted the advisory for Tybee Strand Beach at the Pier, which stretches from 11th Street to 18th Street on Tybee Island.

The advisory was issued on June 25, 2019 after routine water quality tests showed a high level of enterococci bacteria which increase the risk of gastrointestinal illness in swimmers.

Subsequent water samples showed the bacteria level had dropped below Environmental Protection Agency’s recommended limits. Therefore, the advisory was lifted.

June 25, 2019

The Chatham County Health Department has issued a beach water quality advisory for Tybee Strand Beach at the Pier, which stretches from 11th Street to 18th Street on Tybee Island.

The advisory is only for the area specified above and does not impact any other beaches on the island. There is no way of knowing if going into water that is under advisory will result in illness; however, this beach water advisory is to alert the public of a possible risk of illness associated with water contact. An area under advisory does not mean the beach is closed.

Water samples are collected weekly on Tybee Island and are tested for enterococcus (pronounced: en·ter·o·coc·cus) bacteria which is found in warm blooded animals including humans but also birds, raccoons, deer, dolphins and other wildlife. It is difficult to determine exactly where the bacteria come from, but some sources could include animal waste, storm water runoff, or boating waste. When a beach is under advisory, it means that the level of bacteria found in the water is above the Environmental Protection Agency’s recommended standards.

The Chatham County Health Department recommends you do not swim or wade in the water in the area under advisory. Fish and other seafood caught from the advisory area should be thoroughly washed with fresh water and thoroughly cooked before eating, as should fish or seafood caught from any waters.

The area will be retested and the advisory will be lifted when tests show the bacteria level meets the Environmental Protection Agency’s recommended standards.

Frequently Asked Questions about Beach Water Advisories
Why is the water tested and what is it tested for?
The water is tested as part of the Environmental Protection Agency’s beach monitoring program which includes all Georgia beaches. Water samples are taken all along the island and tested for enterococcus (pronounced: en•ter•o•coc•cus) bacteria which is found in warm blooded animals including humans but also birds, raccoons, deer, dolphins and other wildlife.

Do you know where the bacteria come from?
It is difficult to determine exactly where the bacteria come from but some sources could include animal waste, storm water runoff, or boating waste.

What does it mean when a beach is under advisory?
It means that the level of bacteria found in the water is above the Environmental Protection Agency’s recommended standards. When the level of bacteria is higher than it should be there is increased risk of illness to swimmers so the public is advised not to swim or wade in the water in that particular area.

Will I get sick if I go into water that is under advisory?
There is no way to say for sure whether or not you will get sick if you go into water that is under advisory but you will be at an increased risk of illness. Risk of illness comes from contacting beach water in several ways including ingesting water while swimming, getting water in the nose, eyes, and ears or getting water in an open wound. Some examples of possible illness include possible stomach upset, ear infection, sore throat, or wound infection.

What do I do if I have been swimming in water that was under advisory but I didn’t realize it?
There is no way to say for sure whether or not you will get sick if you were swimming or wading in water that was under advisory. The best thing to do is to be aware of any changes in your health. If you start to experience stomach upset, ear infection, sore throat, or wound infection, after you have been in contact with water that was under advisory, contact a healthcare provider.

Is the beach closed?
No, the beach is not closed. An advisory simply means that increased levels of bacteria were found in the water, not on the beach, which is why public health suggests no swimming or wading in the water (risk of illness comes from contact with the water).

Does the advisory cover the entire island?
No. An advisory only covers a certain area. Even if part of the beach is under advisory there are plenty of other beach access points to areas that aren’t under advisory.

How do you know the bacteria are only in one certain area of the water?
Beaches have been divided up into zones. Water samples are taken from the center of each zone and if bacteria levels are found to be higher in a certain zone then an advisory is issued for that area. Because it’s not possible to determine exactly where the bacteria levels switch from “okay” to “elevated,” the advisory is issued for a fairly large area. If water samples from more than one zone indicate higher levels of bacteria then multiple advisories will be issued but again, only for the areas where bacteria is higher.

How long do areas stay under advisory?
When an advisory is issued, another sample of the water in the area under advisory is taken within a few days and retested. An area will stay under advisory until the test shows that bacteria in the water have decreased to an acceptable level as determined by the Environmental Protection Agency.

How often is beach water tested?
Water at the beaches on Jekyll, St. Simons, and Tybee Islands is tested once a week, year-round. Beaches that are under permanent advisory are tested once a quarter (four times a year).

What does it mean if a beach is under a permanent advisory?
A permanent advisory means that there are continually elevated bacteria levels indicating a potential human health risk and therefore swimming or wading is advised against.

Can I eat fish I’ve caught from a beach that’s under advisory?
Yes, fish and other seafood caught in area(s) should be thoroughly washed with fresh water and thoroughly cooked before eating as should fish or seafood caught from any waters.
