The CDC’s public health response to Hurricane Katrina continues with 216 public health professionals deployed to affected areas. Vigilant disease, environmental, injury and mental health surveillance is ongoing. A cluster of 30 adults and children in a Texas evacuation center have skin abscesses: cultures from some of these patients indicate methicillinresistant Staphylococcus aureus (MRSA) infection. MRSA is endemic in the United States and can occur as community outbreaks (e.g., football teams). Infection control and personal hygiene measures are ongoing.

National Public Health Emergency Situation Update:

• Persons in Evacuation Centers: 348 open, 62,332 people in 18 states (numbers fluctuate daily)

• Damage Assessments: 403,000 without power (435,000as of 9/13)

Public Health Recommendations: Pass it on

Prevent and Treat Trench Foot or Immersion Foot

Trench foot, also known as immersion foot, occurs when the feet are wet for long periods of time. It can be quite painful, but it can be prevented and treated.

Symptoms of trench foot include a tingling and/or itching sensation, pain, swelling, cold and blotchy skin, numbness, and a prickly or heavy feeling in the foot. The foot may be red, dry, and painful after it becomes warm. Blisters may form, followed by skin and tissue dying and falling off. In severe cases, untreated trench foot can involve the toes, heel, or entire foot.

When possible, air-dry and elevate your feet, and exchange wet shoes and socks for dry ones to help prevent the development of trench foot. Treatment for trench foot is similar to the treatment for frostbite. Take the following steps:

Thoroughly clean and dry your feet.

Put on clean, dry socks daily.

Treat the affected part by applying warm packs or soaking in warm water (102° to 110° F) for approximately 5 minutes.

When sleeping or resting, do not wear socks.

Obtain medical assistance as soon as possible.

If you have a foot wound, your foot may be more prone to infection. Check your feet at least once a day for infections or worsening of symptoms. www.bt.cdc.gov/disasters/trenchfoot.asp.
