Climate change, droughts and health: NPHW emphasizes preparedness

This National Public Health Week — which is going on right now! — we’re focusing on making the U.S. the healthiest nation. Getting there means we need to address a number of issues, including climate change. Climate change and extreme weather are threatening U.S. health, and if we don’t do something about them there’ll be increases in disease, injury and death.

One of the big effects of climate change that scientists are worried about are droughts, which could make water supplies scarce. Droughts can even cause more cases of West Nile virus, research shows.
Both before and during droughts, there are steps we can all take to conserve water:

• Reduce shower times and use high-efficiency showerheads to use less water and conserve energy.
• Use energy-efficient washing machines and make sure to wash full loads of laundry instead of more frequent small loads.
• Turn off your sprinklers when it’s raining. The Environmental Protection Agency recommends checking your lawn by stepping on the grass and seeing if it springs back as an indicator of whether it needs more water. Pay attention to local restrictions on water use during droughts.
• Educate your community about the importance of water conservation and why everyone needs to do their part.

In the (flood) zone with climate change

In 2014, there were eight weather-related disasters, with losses exceeding $1 billion each across the U.S. Go ahead, have a look at the list. How many of those disasters were storms and floods? Too many! The bad news is that we all live in a flood zone. According to the National Flood Insurance program “in the past five years, all 50 states have experienced floods or flash floods.”

But before we get too far into floods, let’s talk for a minute about greenhouses. Certain gases in the atmosphere — we call them greenhouse gases — help to keep Earth warm by trapping heat from the sun, just like a greenhouse does. Without greenhouse gases, Earth would be too cold to support life as we know it.

However, scientists are measuring higher-than-normal levels of greenhouse gases, which are being trapped in Earth’s atmosphere. Our greenhouse, our planet, is becoming too warm because of the increasing level of greenhouse gases. We’re not cooling off enough. As the North Pole warms up, it’s easier for high-pressure systems from the ocean to move in on cold air in the North Pole and push it south.

And that’s where climate effects such as storms and floods come in. For example:

• Oceans are warmer: Water takes up more space as it heats and it has to go somewhere. And it’s rising up on shorelines. 
• Global air and wind currents are warmer: When air currents of high and low energy collide, they produce storms. Warmer air means more frequent and violent storms. Warm oceans also add to overheating air and wind currents. 
• The North Pole is warmer: Glaciers are melting into the ocean, adding to the amount of water. 

Now for some fast facts about floods:

• Floods can come on rapidly, such as a flash flood, or slowly build up, such as a rising creek during a slow, steady rainfall.
• Flooding can spread over large areas or occur over a small area. 
• Floods have many causes, including rainfall, snow melt, a rising body of water or a broken dam. 
• During a flood, shallow creeks streams or dry beds can become very deep. Roads can become torrential rivers washing away vehicles and people. Don’t get in, don’t take that chance!
• You may see an increase of unwanted “guests” after a flood, such as mosquitoes. Mosquito bites aren’t only annoying, they can spread dengue, West Nile virus or chikungunya, among other diseases.

Summer Safe: Don’t let these three infectious diseases ruin your summer fun

Do your late summer plans include a trip to a state or county fair? How about a camping trip, or perhaps a visit to a local farm?

Reports of infectious diseases spread by animals and insects have been on the rise this summer. Here are three infectious diseases that have been in the news recently, along with tips for how you can protect yourself and your loved ones.

H3N2v, aka “swine flu,” from pigs

In the last few weeks, the Centers for Disease Control and Prevention has reported new cases of a type of influenza, H3N2v, that comes from pigs. Most of the people who got sick with this new type of flu had direct contact with pigs on farms or at state and county fairs. If you work around pigs or if you will be attending a fair or farm show, follow these tips to protect yourself:

• Always wash your hands after touching animals.
• Don’t eat or drink if you’re in an animal enclosure, and keep your hands away from your face.
• If you have a weak immune system or are at high-risk for flu, stay away from pigs. This includes young children and adolescents, pregnant women, people who are already sick and people ages 65 and older.
• Stay away from any animal that looks sick or acts strange. Call a veterinarian if you suspect that an animal is sick.

Salmonella from baby chickens
Live baby poultry such as ducklings and chickens are adorable — what kid can’t resist picking up one of these cute, fuzzy, chirping animals? Don’t let their cuteness fool you: These animals can pose a health risk, especially to young children. Baby poultry, found in petting zoos, fairs and even in classrooms or at home, have been known to spread salmonella.

This year alone, baby chickens have been linked to salmonella cases in states around the country. Here are some tips to prevent illness from salmonella:

• Don’t let children younger than age 5 touch or handle chicks or ducklings.
• Don’t bring chicks, ducklings or other live poultry into your house.
• Make sure anyone who handles baby poultry washes their hands thoroughly with soap and water. Adults should help young children wash their hands. For information about hand-washing for any age group, check out our collection of Get Ready fact sheets!

CDC has more information on salmonella and baby birds on its website.

West Nile virus from mosquitoes

So far this year, 42 states and the District of Columbia have reported West Nile infections in people, birds or mosquitoes. People get West Nile virus when they are bitten by mosquitoes that carry the disease. You can’t tell if a mosquito is infected just by looking at it, so the best protection is to prevent mosquito bites.

• When you go outdoors, use insect repellent — especially at dusk and dawn, when mosquitoes are most active.
• Wear long sleeves and pants when possible.
• Mosquitoes breed in still water, so remember to empty out barrels, flowerpots and buckets that are filled with water on your property or in your neighborhood. 
• Learn more about protecting yourself from mosquitoes by checking out our fact sheet (PDF).

Even though these infectious diseases are on the rise, protecting yourself can be as simple as washing your hands and wearing bug spray. We hope this helps you stay safe this summer!
