Respiratory Illnesses
Respiratory illnesses such as COVID-19, influenza (flu), and respiratory syncytial virus (RSV) are contagious infections that are all caused by different viruses. These illnesses primarily affect the respiratory system and can follow seasonal patterns.
Respiratory illnesses spread when a person who is sick breathes out droplets and very small particles that contain the virus. These droplets and particles can be breathed in by other people or land on their eyes, noses, or mouth. In some circumstances, they may contaminate surfaces they touch.
- COVID-19 is caused by the coronavirus SARS-CoV-2. It can present with common symptoms like fever and headache as well as unique symptoms that can and include fatigue, shortness of breath, loss of taste and/or smell.
- Influenza (flu) is a virus that infects the nose, throat, and occasionally the lungs. Flu can cause mild to severe illnesses in humans. It can cause symptoms like fever, cough, and body aches. Seasonal flu (influenza A and B) is detected year-round but fall and winter is considered flu season.
- RSV a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious. Infants and older adults are more likely to develop severe RSV and need hospitalization. Vaccines are available to protect older adults from severe RSV. Monoclonal antibody products are available to protect infants and young children from severe RSV.
DCHD encourages everyone to take steps year-round to help reduce the spread of respiratory viruses and limit their impact on our families and community. Stay up to date on vaccinations. Practice proper handwashing. Stay home if you are sick. Get tested. Be mindful of not exposing vulnerable friends and family. Consider wearing a mask in appropriate settings. Seek medical advice and care if you have severe symptoms.
