As the seasons change, many people start experiencing problems such as cough, cold, sore throat, runny nose, fever and body aches. Respiratory illnesses can spread more easily in certain seasons and environments, particularly when people spend more time indoors or in crowded places.
Common respiratory illnesses include the flu, common cold, COVID-19 and RSV. While not every illness follows the same seasonal pattern, respiratory viruses can circulate throughout the year, with some becoming more common during particular seasons.
The good news is that a few simple everyday habits can help reduce your risk of getting sick and spreading infections to others.
Why Do Seasonal Infections Spread?
Several factors can contribute to the spread of respiratory infections. People may spend more time indoors, where close contact and poor airflow can make it easier for some viruses to spread. Crowded spaces and contact with someone who is already sick can also increase exposure.
Different viruses spread in different ways. Many respiratory viruses can spread through respiratory particles released when an infected person coughs, sneezes or talks. Some can also spread when contaminated hands or surfaces are touched and then the eyes, nose or mouth are touched.
Common Symptoms to Watch For
Seasonal respiratory infections can cause different symptoms depending on the virus. Common symptoms may include:
- Cough
- Runny or blocked nose
- Sore throat
- Sneezing
- Fever or chills
- Headache
- Tiredness
- Body aches
A common cold often causes milder symptoms, while flu can cause more noticeable fever, body aches, fatigue and cough. Symptoms can overlap, so it is not always possible to identify the virus based on symptoms alone.
Simple Ways to Protect Yourself
- Wash Your Hands Regularly
Good hand hygiene remains one of the easiest ways to reduce the spread of germs. Wash your hands with soap and water regularly, particularly after coughing or sneezing and before eating.
If soap and water are not available, an alcohol-based hand sanitizer containing at least 60% alcohol can be used.
- Cover Coughs and Sneezes
Use a tissue when coughing or sneezing and dispose of it properly. If a tissue is not available, cough or sneeze into your elbow rather than your hands.
These simple habits can help reduce the spread of respiratory germs to people around you.
- Improve Indoor Airflow
Respiratory viruses can spread more easily in crowded indoor environments with poor airflow. Whenever possible, open windows or doors to bring in fresh air, improve ventilation or consider using an appropriate air purifier.
- Avoid Close Contact When Someone Is Sick
If someone around you is unwell, maintaining some distance can help reduce your chance of exposure. Similarly, if you are sick, limiting close contact with others can help protect family members, colleagues and friends.
- Stay Home When You Are Unwell
If you have respiratory symptoms, staying away from others while you recover can help prevent the infection from spreading.
CDC guidance says people can return to normal activities when their symptoms have been improving overall and they have been fever-free for at least 24 hours without using fever-reducing medication. Additional precautions are recommended for the following five days.
- Keep Recommended Vaccinations Up to Date
Vaccination is an important part of preventing serious respiratory illness. Depending on your age, health conditions and local recommendations, vaccines may be recommended for illnesses such as influenza, COVID-19 or RSV.
Speak with a healthcare professional about which vaccines are appropriate for you and your family.
When Should You Seek Medical Help?
Most mild respiratory infections improve with time, but some people have a higher risk of developing serious illness. Infants, older adults, pregnant people, people with weakened immune systems and people with certain underlying medical conditions may need extra care.
Seek medical attention if symptoms become severe or continue to worsen. Difficulty breathing, chest pain or other emergency warning signs require prompt medical attention.
A Few Healthy Habits Can Make a Difference
There is no single way to completely avoid every seasonal infection. However, basic precautions such as regular handwashing, covering coughs and sneezes, improving indoor ventilation, avoiding close contact when sick and staying up to date with recommended vaccinations can help reduce the risk of respiratory illness.
Staying aware of symptoms and taking sensible precautions can protect not only you but also the people around you.
