There has been an increase in the number of patients treated for gastrointestinal and flu-like symptoms at Mercy Memorial Hospital, but no confirmed cases of influenza, a hospital official said Friday.
On Thursday, more than five adult cases with nausea and vomiting were handled in the emergency department, said Jackie Swearingen, marketing and public relations director for the hospital.
Dr. Mark Sherrard, chief medical officer for the hospital, said signs and symptoms of flu include fever or feeling feverish, chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches and fatigue. Some people may have vomiting and diarrhea, but this is more common in children than adults.
Most experts believe that flu viruses spread mainly by droplets made when people with the flu cough, sneeze or talk, Dr. Sherrard said. These droplets can land in the mouths or noses of people nearby.
"You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick," he said. "Most healthy adults can infect others beginning one day before symptoms develop and up to seven days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time."
The most effective way to prevent illness is by receiving a flu vaccine every year. People can obtain a shot from their primary care physician.
"The best way to prevent the spread of flu, first and foremost, is good hand hygiene," Dr. Sherrard said. "Washing your hands properly for two minutes with an antibacterial soap will help eliminate germs."
Here are other actions recommended:
• Cover your mouth and nose when coughing or sneezing — either with a tissue or by coughing into your sleeve.
• Avoid touching your eyes, nose and mouth, which can spread germs, he said.
• "Stay home when you are sick," Dr. Sherrard advised. "This will prevent the flu from spreading at your place of work or school. School-age children are especially prone to close spaces and bringing home the flu to everyone in the household."
