“The flu can spread when you touch the infected droplets from a cough or sneeze and then touch your own eyes, mouth or nose,” says Dr. Manish Sadarangani, a pediatric infectious diseases physician and Director of BC Children's Hospital's Vaccine Evaluation Center. “Washing your hands and getting the flu shot are key to keeping the flu from infecting your family and others around you. It’s a bad illness we want to stop from spreading.”
Healthy people can get very sick from the flu. It can trigger a fever that can last three to four days, a severe headache, aches and pains, up to three weeks of fatigue, a runny nose, sneezing, coughing and a sore throat. Children can also experience nausea, vomiting or diarrhea. Complications can lead to pneumonia and respiratory failure.
Infected people can spread the flu up to one day before and five days after they start showing symptoms. Getting sick with the flu can put others at risk of life-threatening complications, including very young children, seniors 65 and older, and people who have lung or heart disease, chronic health conditions or weakened immune systems. Healthy pregnant women who get the flu in the second half of their pregnancy are also at greater risk of hospitalization.
The flu shot is safe and effective at preventing illness, especially when combined with proper hand hygiene and staying home when sick.
“Some people worry about getting the flu from the vaccine, but it won’t give you the flu because the vaccine doesn’t contain a live virus,” says Sadarangani. “Mild side-effects can occur, but this rarely lasts for more than 48 hours.”
