5 Hurricane Health Dangers
The heavy flooding and damage caused by hurricanes can bring you in contact with hidden germs that cause disease. These storms can also affect your ability to get medications you may need if you get sick, or in your day-to-day life. However, it’s possible to minimize your risk and help protect yourself from these hurricane-related threats.
To stay safe, one of the best things you can do is practice good hygiene, including frequent hand washing and wound care. Washing your hands with soap and water from clean sources—like emergency hand-washing stations set up by local and governmental rescue organizations—is one of the best ways to reduce the number of germs you’re exposed to. If you have an open wound on your body, it’s important to keep the wound clean and covered to help prevent infections. However, if you develop signs of any infection or illness, it’s important to seek assistance from your doctor immediately. Your doctor can help you if you start to experience any symptoms of the diseases that are common during hurricanes.
1. Gastrointestinal Diseases
Many problems that occur after hurricanes are the result of flooding that washes water from sewage systems, farms, and other water sources into communities and drinking water facilities. This causes the spread of viral and bacterial contaminants, such as E. coli, salmonella, norovirus, and hepatitis.
Other germs found in contaminated water can cause many serious diseases, including:
Dysentery, an infectious disease caused by bacteria or amoebas, which are small, parasitic organisms that invade body tissues. Dysentery is a serious illness that causes severe gastrointestinal symptoms, like bloody diarrhea, abdominal pain, fever, and dehydration.
Cholera, an infection caused by bacteria which leads to watery diarrhea. Cholera can cause severe dehydration quickly, which can be fatal if left untreated. However, most people infected with cholera will have only mild symptoms or no symptoms at all.
Some of these diseases, like cholera and typhoid fever, are rare in industrialized countries, but can still occur during natural disasters. You can help protect yourself against these threats by practicing good hygiene, avoiding any food or drink contaminated by flood water, and avoiding contact with flood water as much as possible.
2. Respiratory Problems
Flood waters surrounding buildings and homes make it more likely for mold to grow. Mold spores can make breathing difficult for everyone, especially people with existing mold allergies or asthma. Also, if you have certain medical conditions, like chronic obstructive pulmonary disease (COPD), you may be more at risk for developing infections in your lungs.
To stay safe around mold, be sure to wear proper protective gear, like an N95 mask, that covers your nose and mouth. These masks can help prevent mold spores from entering your airways. If you have difficulty breathing at any time, seek professional medical help immediately.
3. Skin Infections
Some bacterial contaminants, like Vibrio vulnificus, live in warm coastal waters and can easily be washed ashore during a hurricane. Others, like Methicillin-resistant Staphylococcus aureus (MRSA) are sometimes passed from person to person in cramped conditions. Both types of bacteria can cause severe skin infections. When disasters like hurricanes strike, you may be exposed to flood waters or take refuge in a crowded shelter, which can increase your risk.
You can help protect yourself from skin infections by practicing good hygiene, keeping wounds clean and covered, avoiding contact with flood waters, and avoiding sharing personal items like razors or towels. If you notice any redness, swelling, pain, or blisters that are full of fluid or pus anywhere on your skin, including any wounds you may have, it’s important to seek medical help immediately.
4. Diseases Caused by Insects
After hurricanes, diseases like West Nile and Zika can be spread by mosquitos. Take steps to protect yourself by using insect repellant that contains active ingredients like DEET, lemon eucalyptus oil, or picaridin. Also, be sure to wear clothing that covers your arms and legs. Because mosquitos lay their eggs near water, it’s important to empty any containers around your home that could hold water. Also, be sure to use screens on windows and doors—if that option isn’t available, use mosquito netting to help keep bugs out.
5. Medication Shortages
Because of the flooding that may occur during hurricanes, you may not be able to visit your regular pharmacy to purchase medications you need. However, it’s common for local hospitals and some pharmacies to remain open during hurricanes, and many continue to operate after the storm has passed. If you run out of medication, or experience a health event because of a medication shortage, your local hospital may be able to assist you. But keep in mind your dose of medication may be lower than normal—it is not unusual for healthcare facilities in hurricane affected areas to ration medications in order to provide doses to the greatest number of people possible.
