Pertussis is a highly contagious bacterial infection that causes coughing and gagging with little or no fever. An infected person has cough episodes that may end in vomiting or cause a "whoop" sound when the person inhales. Adults usually have two to three coughing spells per day and children often have 10 or more coughing spells per day.General Information and Fact Sheets about Pertussis

Chicken Pox (Varicella)
Both chicken pox and shingles are caused by the same “varicella” virus. Chickenpox is most common in young children, whereas shingles is most common in adults. Chicken pox is very contagious with most children in the United States experiencing chickenpox before they are school-aged. The disease is spread by close contact (sharing breathing space or direct touching contact) with infected discharge from the nose, throat or rash. A vaccine against chicken pox is now available. Shingles usually occurs in individuals over the age of 50. It is not as contagious as chicken pox but can cause severe discomfort due to the rash it causes. To prevent chicken pox infection to others, it is important to stay home until the last blister has crusted over (about 5 days).Learn more about Chicken Pox
Tick born diseases are caused by bacteria transmitted to humans through the bite of an infected tick. Examples of tick borne diseases include Lyme disease, Ehrlichiosis and Rocky Mountain Spotted Fever (RMSF). Anyone is susceptible to these diseases, but persons who spend time outdoors in tick-infested environments are at increased risk of exposure. Although ehrlichiosis and RMSF are less likely to occur, infected deer ticks are present in Illinois and can transmit Lyme disease. Learn more about tick-borne diseases.
Foodborne disease is caused by consuming contaminated foods or beverages. Many different germs can contaminate food, so there are many different types of foodborne infections. More than 250 different foodborne diseases have been described. Most of these diseases are infections, caused by a variety of bacteria, viruses, and parasites. These different diseases have many different symptoms, so there is no one "syndrome" that is foodborne illness. Common symptoms associated with foodborne illness are nausea, vomiting, abdominal cramps and diarrhea. See the below related links for information regarding the most common food and waterborne illnesses.

Rabies is an almost always fatal disease that affects the nervous system of humans and other mammals. However, this disease is fully preventable with timely vaccinations and Immune globulin (IG) after an exposure. Most commonly people get rabies from the bite of a rabid animal. In other cases, people can contract rabies if any infectious material from a rabid animal (such as saliva) comes in contact with one's nose, mouth an open wound or gets directly into the eyes.
Pre-exposure rabies vaccine may be available at Walgreen's Take Care locations.
Back to School Health
With summer winding down it’s now time to focus on back to school. To keep children healthy, make sure they have plenty of rest and a nutritious diet. Make sure they have appropriate clothes for the different seasons. Show your child the proper way to wash their hands and remind them to do it frequently throughout the day. Make sure to use soap and water and rub hands together for at least 20 seconds. Limit touching areas such as the eyes, nose or mouth. Teach your child to cover coughs and sneezes with a tissue or their arm. Minimize the time your child spends with others who are ill. Avoid sharing personal items such as hats, brushes, combs, lip balms or towels. Should your child come down with an infectious condition such as strep throat, chickenpox, scarlet fever, pertussis, head lice, etc., it is important to notify the school.Learn more about Group "A" Strep, Human Parvovirus B-19 (Fifths Disease), Sick Day Guidelines for Parents and Immunizations
NorovirusNoroviruses are a group of viruses that cause gastrointestinal illness or "stomach flu." Norovirus, which is most common during the winter months, is highly contagious and can spread easily. Outbreaks occur where there are more people in a small area, such as nursing homes, restaurants, catered events and cruise ships. Good hygiene practices are important to prevent transmission from person to person.
