Winter brings more than just chilly weather, it also marks the peak of cold and flu season. For cancer patients whose immune systems may be compromised by chemotherapy, radiation, or other treatments, this time of year can increase infection risk. Viruses spread more easily in enclosed spaces, and dry indoor air can irritate the respiratory tract, making it easier for infections to take hold. That’s why it’s essential for both patients and caregivers to take proactive steps to stay healthy during the colder months.
“During the winter months, cancer patients face a higher risk of infection due to weakened immune systems and increased exposure to seasonal viruses,” said Dr. Curry McEvoy, medical oncologist at Southern Cancer Center. “That’s why we emphasize proactive prevention. Simple steps like handwashing, avoiding sick contacts, and staying up to date on vaccinations can make a big difference in protecting your health.”
Practice Good Hand Hygiene
Frequent handwashing is a simple yet powerful way to prevent the spread of germs. Use soap and water for at least 20 seconds, especially:
- After being in public places
- Before eating or preparing food
- After using the restroom
When soap and water aren’t available, use an alcohol-based hand sanitizer with at least 60% alcohol.
Avoid Contact with People Who Are Sick
Politely ask friends or family members who are feeling unwell to postpone their visit. Caregivers should monitor their own health closely and have a backup plan in case they become ill.
Monitor for Fever
A fever can be an early sign of infection. Cancer patients should:
- Take their temperature regularly
- Treat any fever over 100.4°F (38°C) as a medical emergency
- Contact their healthcare provider if a fever develops
Keep Your Environment Clean
Keeping your home clean and well-ventilated can reduce the risk of infection:
- Disinfect high-touch surfaces like doorknobs, light switches and remote controls
- Use HEPA filters or open windows briefly to improve air circulation
Outside of the home, try to avoid crowded indoor spaces when possible, especially during peak flu season.
Nutrition and Rest
Give your immune system the support it needs with a nutritious diet and adequate rest.
- Eat a balanced diet rich in fruits, vegetables and lean proteins
- Limit processed foods and added sugars
- Aim for 7–9 hours of sleep per night
- Consult your provider if you have dietary restrictions or side effects from treatment
Get Vaccinated
Vaccines are one of the most effective tools for preventing serious illness. Cancer patients should talk to their healthcare provider about:
- Flu shots (injectable only—avoid the nasal spray version)
- COVID-19 boosters
- RSV vaccines, if eligible
Caregivers and household members should also stay up to date on their vaccinations.
