Seasonal Viral Infections: Understanding Symptoms and Prevention

By Currex Hospital Infectious Diseases & Preventive Care Team

As the seasons change, so do the types of illnesses we encounter. These seasonal viral infections
are common but can be managed?and often prevented?with the right awareness and care.
Understanding why these infections surge during certain times of the year can help you protect
yourself and your loved ones all year round.

What Are Seasonal Viral Infections?

Seasonal viral infections are illnesses caused by viruses that peak during specific times of the year,
often as a result of environmental and behavioral changes. While these viruses circulate year-round,
their activity tends to rise during certain weather conditions.

Common Seasonal Viral Infections

• Influenza (Flu): A contagious respiratory infection that peaks in colder months.
• Common Cold: Caused by rhinoviruses and others, this infection is widespread year-round.
• Respiratory Syncytial Virus (RSV): Affects the lungs and airways, especially in infants and the
  elderly.
• Norovirus: Causes gastroenteritis and spreads rapidly in winter or close-contact settings.
• Adenovirus: Leads to respiratory, eye, and gastrointestinal infections, often seen in cooler
  seasons

Why Do Viruses Peak in Certain Seasons?

1. Environmental Conditions: Many viruses thrive in cooler, dry air. The flu virus is more stable in
   cold weather, and respiratory viruses spread easily indoors during winter.

2. Increased Indoor Gatherings: Cold weather keeps people indoors, promoting close contact and
   viral transmission.
3. Weakened Immune Defenses: Reduced sunlight lowers Vitamin D levels, weakening immunity.
   Stress and fatigue further increase vulnerability.
4. Viral Mutation and Adaptation: Some viruses, like influenza, undergo genetic changes annually,
   allowing them to re-emerge in new forms.
5. Schools and Workplaces: Children returning to school or adults working indoors in winter often
   drive seasonal viral outbreaks

How Do Seasonal Viruses Spread?

In Older Children:

• borne droplets: When an infected person coughs or sneezes.
• Surface contamination: Viruses can survive on doorknobs, phones, and countertops.
• Direct contact: Handshakes, hugs, or sharing utensils.
• Fecal-oral route: Common with norovirus via contaminated food or poor hygiene.

Common Symptoms

• Fever and chills
• Sore throat or cough
• Runny or stuffy nose
• Fatigue or body aches
• Nausea, vomiting, or diarrhoea
• Shortness of breath (in RSV or flu)

1. Get Vaccinated: Flu and other vaccines strengthen immunity and prevent complications.

2. Practice Good Hygiene: Wash hands frequently or use alcohol-based sanitizer.
3. Avoid Close Contact: Stay home when unwell and avoid contact with sick individuals.
4. Strengthen Immunity: Eat a balanced diet, stay active, and sleep well.
5. Disinfect Surfaces: Regularly clean frequently touched objects.
6. Cover Coughs and Sneezes: Use tissues or your elbow to reduce droplet spread.
7. Stay Hydrated: Fluids help your body recover faster and relieve symptoms.
