Doctors at Patient First in York continue to treat patients with influenza, strep throat, stomach bugs and are seeing an increase in pneumonia cases.
Dr. Linda Taylor says fatigue, along with heavy cough and shortness of breath, are some of the warning signs associated with pneumonia.
"Typically we see shortness of breath," Taylor said. "It seems like they can't get a deep breath and they have a fever."
Taylor said many people fight their sickness at home, but they should seek medical attention if they have a bad fever, have difficulty breathing or develop a rash.
She said they have seen fewer cases of people suffering from the stomach bug, but advises those who have it to drink clear liquids. Anyone who can't keep anything down for 24 hours should visit their physician.
Doctors also recommended that to prevent getting sick, everyone should wash their hands several times during the day and avoid touching their noses, mouths and eyes.
