West Nile Virus: A Seasonal Epidemic in North America

This summer North America is once again experiencing a “seasonal epidemic” of West Nile virus that is expected to last through the fall.  According to the Centers for Disease Control and Prevention (CDC) website, the mosquito-borne virus has been reported in 42 US states as of August 11, 2015.  Fortunately, most people who are infected with the virus show no symptoms; about 20 percent of people infected develop mild symptoms (e.g., headache, body aches, joint pains, vomiting, diarrhea or rash) after three to 14 days.  Less than one percent of those infected become seriously ill (e.g., high fever, muscle weakness, neck stiffness, stupor, and potentially permanent or fatal neurological disease).  There are no medications to treat West Nile virus, nor vaccines to prevent human infection1.  Avoiding West Nile virus is primarily a matter of avoiding mosquito bites.

West Nile Virus Transmission

According to the Centers for Disease Control and Prevention (CDC) website, the West Nile virus cycles between mosquitoes and birds.  Mosquitoes become infected with the virus by biting infected birds; they then pass the virus to humans and other mammals through mosquito bites.  West Nile virus is believed to have been in the US since about 1999 when it was first detected in New York City, but human infections have been reported in many countries for over 50 years.  According to the World Health Organization website, the virus is found in Africa, Europe, the Middle East and West Asia, in addition to North America.

West Nile virus can kill some host birds when the virus concentrates in their blood.  Sightings of multiple dead birds could be a sign that the virus is circulating in the vicinity.  CDC notes reporting dead birds to county and state health departments may be helpful to West Nile virus monitoring activities.  Additionally, some health departments monitor mosquitoes for the West Nile virus, which may be supplemented by monitoring sentinel chickens and dead birds.  According to the CDC report, “West Nile Virus in the United States:  Guidelines for Surveillance, Prevention, and Control,” “Research and operational experience shows that increases in WNV [West Nile virus] infection rates in mosquito populations can provide an indicator of developing outbreak conditions several weeks in advance of increases in human infections.”  (The report is linked to this CDC website.)

Reducing Your Risk of West Nile Virus is a Three Step Process

  • First, know your inherent risk level. People over 50 years of age have a greater chance of developing serious symptoms of West Nile virus than those younger than 50.
  • Second, know when to expect the “enemy.” Many mosquitoes are most active from dusk to dawn; these are the hours during which special precautions may be warranted, including avoiding being outdoors.
  • Third, take steps to avoid mosquitoes and their bites.
    • When outdoors, use effective insect repellents; those containing DEET,  picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products may provide longer-lasting protectionfollow label directions for use (For more information on insect repellents and their effectiveness, please see http://cfpub.epa.gov/oppref/insect/.)
    • Wear long sleeves and long pants of tightly woven fabric; tuck pant legs into socks for extra protection
    • Inspect and repair screens on windows and doors
    • Remove standing water in flower pots, buckets, barrels, old tires, untreated kiddie pools and other containers that can serve as breeding grounds for mosquitoes
    • Make sure backyard pools are appropriately chlorinated; mosquitoes will not breed in chlorinated water
    • When you are outdoors, air movement around your body (from fans or natural breezes) disrupts mosquito flight and reduces your risk of being bitten.

Your local health department may provide additional information about protecting against mosquito-borne diseases in your area.

What to do if You Think You Have West Nile Virus

According to CDC, mild symptoms of West Nile virus will improve on their own without medical intervention.  Severe West Nile virus symptoms may require hospitalization.  West Nile virus is not spread from casual human contact, such as touching or kissing.  If you have severe symptoms and think you may be infected with the West Nile virus, seek medical attention immediately.

What to do about Bird (and Other) Droppings in the Swimming Pool

healthy pools - Fri, 08/07/2015 - 10:13

There’s nothing like a swim in an outdoor pool in beautiful summer weather. As the open air is the domain of nature’s flying creatures, however, the occasional splat of bird droppings in the pool is to be expected. What, if anything, needs to be done about bird droppings in the pool?

According to the US Centers for Disease Control and Prevention (CDC) website, many germs that might be present in bird droppings can infect humans, although few, if any, outbreaks have been associated with bird droppings. Duck and goose droppings are highlighted by CDC as potentially containing E. coli, Salmonella, Campylobacter or Cryptosporidium. Fortunately, in a well-maintained pool most pathogens in bird droppings are killed by chlorine within minutes, according to CDC. Cryptosporidium, a microscopic parasite surrounded by a tough chlorine-resistant outer shell, can be removed by a well-maintained pool filtration system.

Addressing Bird (and Other Types) of Droppings in the Pool

CDC recommends pool managers and backyard pool owners treat bird droppings in the pool in the same way that they would respond to finding formed human feces in the pool. The goal is to remove the waste material, if possible, and disinfect the water by taking the following steps:

  • Close the pool to swimmers.
  • Put on disposable gloves.
  • Remove the waste material using a net or bucket. Do not vacuum the waste from the pool.
  • Clean off any debris or dirt from the item used to remove the waste.
  • Disinfect the item used to remove the waste by immersing it in the pool during the 30-minute disinfection time described below.
  • Remove and dispose of gloves.
  • Wash your hands thoroughly with soap and water immediately.
  • Raise the free chlorine concentration to, or maintain it at, 2 parts per million (ppm); maintain the pH level at 7.5 or less; keep the temperature at 77°F (25°C) or higher. The free chlorine and pH should remain at these levels for 30 minutes.
  • Confirm that the filtration system is operating properly.

How to Discourage Birds around the Pool

CDC provides the following tips for discouraging birds (not the duck and geese varieties) from frequenting the pool area:

  • Remove plants that produce edible nuts, fruits, and berries.
  • Remove bird feeders.
  • Trim or remove trees and shrubs to limit branches hanging around or over the pool that can be used by roosting birds.

To discourage ducks and geese:

  • Do not keep domestic ducks and geese in the pool area to decrease the likelihood of wild ducks and geese becoming attracted to the area.
  • Do not feed ducks or geese.
  • Ducks and geese eat grass. If possible, reduce the area of grass lawns around the pool or install barriers that control movement between the pool and grass lawns, such as fences, grid wires and hedges. Noise makers, goose repellents and trained dogs can also be used to discourage non-migratory or resident geese from becoming a nuisance.

Happy swimming! For more information on addressing animals and pools, please see this CDC website. For further information on waste products in pools, please see the CDC’s Fecal Incident Response Recommendations for Pool Staff, linked from this CDC web page.
