Hurricane Preparedness: Know the Terms

Listening to weather reports can sometimes bring a flood of new terms you have never heard before. When dangerous storms approach the area, it is important to know what meteorologists mean.

Familiarize yourself with these terms to help identify a hurricane hazard:

Tropical Cyclone: A warm-core non-frontal synoptic-scale cyclone, originating over tropical or subtropical waters, with organized deep convection and a closed surface wind circulation about a well-defined center. Once formed, a tropical cyclone is maintained by the extraction of heat energy from the ocean at high temperature and heat export at the low temperatures of the upper troposphere.

Tropical Depression: A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) is 38 mph (33 knot) or less.

Tropical Storm: A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) ranges from 39 mph (34 knots) to 73 mph (63 knots).

Hurricane: A tropical cyclone in which the maximum sustained surface wind (using the U.S. 1-minute average) is 74 mph (64 knots) or more.

Storm Surge: An abnormal rise in sea level accompanying a hurricane or other intense storm, and whose height is the difference between the observed level of the sea surface and the level that would have occurred in the absence of the cyclone. Storm surge is usually estimated by subtracting the normal or astronomic high tide from the observed storm tide.  Storm surge can reach heights well over 20 feet and can span hundreds of miles of coastline.

Storm Tide: The actual level of sea water resulting from the astronomic tide combined with the storm surge.

Hurricane Warning: An announcement that hurricane conditions (sustained winds of 74 mph or higher) are expected somewhere within the specified area. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane warning is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.

Hurricane Watch: An announcement that hurricane conditions (sustained winds of 74 mph or higher) are possible within the specified area. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 48 hours in advance of the anticipated onset of tropical-storm-force winds.

Tropical Storm Warning: An announcement that tropical storm conditions (sustained winds of 39 to 73 mph) are expected somewhere within the specified area within 36 hours.

Tropical Storm Watch: An announcement that tropical storm conditions (sustained winds of 39 to 73 mph) are possible within the specified area within 48 hours.

Short Term Watches and Warnings: These watches/warnings provide detailed information about specific hurricane threats, such as flash floods and tornadoes.

Hurricane Preparedness Week: Storm Ready

Hurricane season usually starts in June and lasts until November, with the peak season from mid-August to late October. Rather than wait, now is the time to learn about these storms and how to best prepare.

But what’s the big deal? Metro Atlanta shouldn’t worry too much about hurricanes, right? Wrong. Hurricanes can cause catastrophic damage to coastlines and several hundred miles inland.  So while Gwinnett, Newton, and Rockdale Counties are not coastal, hurricanes can still cause damage to the area! Wind damage and inland flooding are two large threats when these storms pass through.

While we cannot prevent hurricanes or other disasters, we can be better prepared for them. Take some time this week to ensure that you are ready this season.  Check the following information on how to:

1)      Create an emergency supply kit

2)      Create an emergency plan for your family

3)      Protect you and your family from Hurricane Winds

4)      Protect you and your family from Inland Flooding

National Infant Immunization Week

National Infant Immunization Week (NIIW) is an annual observance to promote the benefits of immunizations and to improve the health of children two years old or younger. This year marks the 20th anniversary of the week-long observance established to remind parents and caregivers how important it is to protect children against 14 vaccine-preventable diseases through immunization.

Several important milestones already have been reached in controlling vaccine preventable diseases among infants and adults worldwide. Vaccines have greatly reduced infant death and disability caused by preventable diseases in the United States. In addition:

  • Through immunization, we can now protect infants and children from 14 vaccine-preventable diseases before age two.
  • In the 1950s, nearly every child developed measles and unfortunately, some even died from this serious disease. Today, few physicians just out of medical school will ever see a case of measles during their careers.
  • Routine childhood immunization in one birth cohort prevents about 20 million cases of disease and about 42,000 deaths. It also saves about $13.6 billion in direct costs.
  • The National Immunization Survey has consistently shown that childhood immunization rates for vaccines routinely recommended for children remain at or near record levels.

It’s easy to think of these as diseases of the past. But the truth is they still exist. Children in the United States can — and still do — get some of these diseases.  For example, in 2012, preliminary data from CDC reports more than 41,000 cases of whooping cough (pertussis) in the US, including 18 deaths. Most of these deaths were in children younger than 1 year old. This was the highest number of pertussis cases in any one year in the US since 1955.

Our Health Director, Dr. Lloyd Hofer, is a pediatrician.  In this video he shares how he has seen a decrease in preventable diseases as a result of vaccinations.

World Meningitis Day

World Meningitis Day is recognized to raise awareness of meningitis and emphasize the importance of prevention.

Meningitis is a disease caused by the inflammation of the protective membranes covering the brain and spinal cord known as the meninges. The inflammation is usually caused by an infection of the fluid surrounding the brain and spinal cord.

Meningitis may develop in response to a number of causes, usually bacteria or viruses.

Bacterial Meningitis

Bacterial meningitis is caused by bacteria, like Neisseria meningitidis and Streptococcus pneumoniae. It can be a life-threatening infection that needs immediate medical attention.

The most effective way to protect you and your child against certain types of bacterial meningitis is to complete the recommended vaccine schedule. More information on bacterial meningitis is available on the CDC’s website: http://www.cdc.gov/meningitis/bacterial.html

Viral Meningitis

Viral meningitis is often less severe than bacterial meningitis and usually resolves without specific treatment. Most viral meningitis cases in the United States, especially during the summer months, are caused by enteroviruses; however, only a small number of people with enterovirus infections actually develop meningitis.

There are no vaccines for the most common causes of viral meningitis. Thus, the best way to prevent viral meningitis is to prevent the spread of viral infections. Prevention measures include:

  • Wash your hands thoroughly and often, especially after changing diapers, using the toilet, or coughing or blowing your nose.
  • Disinfect frequently touched surfaces, such as doorknobs and the TV remote control.
  • Avoid kissing or sharing cups or eating utensils with sick people; avoid sharing with others when you are sick.
  • Make sure you and your child are vaccinated on schedule. Vaccinations included in the childhood vaccination schedule can protect children against some diseases that can lead to viral meningitis. These include vaccines against measles and mumps (MMR vaccine) and chickenpox (varicella-zoster vaccine).
  • Avoid bites from mosquitoes and other insects that carry diseases that can infect humans.

More information on viral meningitis is also available on the CDC’s website: http://www.cdc.gov/meningitis/viral.html

5 Things to Know About Tuberculosis

1. Is TB still a public health problem worldwide and in the United States?

Fact: TB is one of the world’s deadliest diseases. One-third of the world’s population is infected with the bacteria that causes TB, and each year, over 9 million people around the world become sick with TB disease. Almost 2 million deaths worldwide occur each year from TB.

In the United States, 11,545 TB cases were reported during 2009. While TB rates in the United States have been declining slowly since 1993, there remains a disproportionate burden of TB among racial and ethnic minorities. TB rates are higher for some racial and ethnic groups, probably because a greater proportion of people in these groups have other risk factors for TB.

2. Does everyone who becomes infected with TB bacteria get sick?

Fact: Not everyone infected with TB bacteria becomes sick with TB disease. People who become infected, but are not sick have what is called latent TB infection (LTBI). People who have LTBI do not feel sick, do not have any symptoms, and cannot spread TB bacteria to others. But some people with LTBI go on to get TB disease. People who have TB disease do feel sick, have signs and symptoms, and may spread TB bacteria to others. Learn more about the difference between LTBI and TB disease.

3. Can some people get TB disease easier than others?

Fact: While anyone can get TB disease, some people who get infected with TB bacteria are more likely to get sick. You have a higher chance of getting TB disease if you

  • Have HIV infection
  • Have been infected with TB bacteria in the last 2 years
  • Have other health problems that make it hard for your body to fight disease
  • Abuse alcohol or use illegal drugs
  • Were not treated correctly for TB infection or TB disease in the past

4. What kinds of tests can detect TB infection?

Fact: Two Tests: A skin test or a TB blood test can be used to detect TB infection.

The Mantoux tuberculin skin test is performed by injecting a small amount of fluid (called tuberculin) into the skin in the lower part of the arm. A person given the tuberculin skin test must return within 48 to 72 hours to have a trained health care worker look for a reaction on the arm.

The TB blood test measures how the person’s immune system reacts to the bacteria that cause TB.

Not all people need a TB test. You should get a TB test if you are at increased risk. Conditions or activities that place you at increased risk are:

  • You have spent time with a person known to have TB disease or suspected to have TB disease; or
  • You have HIV infection or another condition that puts you at high risk for TB disease; or
  • You have signs and symptoms of TB disease; or
  • You are from a country where TB disease is very common; or
  • You live or work in the United States where TB disease is more common, such as a homeless shelter, migrant farm camp, prison or jail, and some nursing homes; or
  • You use illegal drugs.

5. How are latent TB infection and TB disease treated?

Fact: LTBI and TB disease can be treated by taking medicine. It is very important that people take the drugs exactly as they are told. If you stop taking the drugs too soon, you can become sick again. If you do not take the drugs correctly, the bacteria that are still alive may become difficult to treat with those drugs. You should take medicine as recommended by a doctor. Learn more about TB treatment.

February is National Heart Month

February is National Heart Month.  According to the CDC, heart disease is the leading cause of death in the United States, and is a major cause of disability.  The most common heart disease in the United States is coronary heart disease, which often appears as a heart attack.

How healthy is your heart?

Knowing your risk factors and what you can to do prevent and control heart disease are great first steps towards having a healthy heart.  Some of the risk factors associated with heart disease are:  High cholesterol, high blood pressure, obesity, diabetes, tobacco use, unhealthy diet, physical inactivity, and exposure to secondhand smoke.

What if you did have a heart attack?  Would you recognize the symptoms?

  • Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness, or pain.
  • Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
  • Shortness of breath. May occur with or without chest discomfort.
  • Other signs. These may include breaking out in a cold sweat, nausea, or lightheadedness.
