Why Viruses Spread More in Winter : Causes, Symptoms & Prevention

Introduction to Seasonal Viral Problems

Health issues in winter are caused by different viruses, bacteria and infection-causing germs that are known to grow and spread more easily in certain seasons, especially when the weather changes, such as during storms or winter. Symptoms like high fever, chills, body aches, headaches, and sometimes a runny nose or sore throat are commonly experienced during these times.

Key Factors That Trigger Viral and Bacterial Growth During Winter

1. Viruses such as the influenza virus, the dengue virus, and even the common cold virus are spread more during these weather changes. Because of this, people are made more vulnerable to infections. The body’s immune system can also be weakened during these periods, especially when proper precautions are not being taken.
2. Seasonal viral illnesses are often caused when the body is affected by weather changes. Sudden shifts in temperature, such as moving from hot to cold or cold to hot, can cause the immune system to become weak. When the body’s defenses are lowered, viruses are easily allowed to enter and cause infection.
   
3. Seasonal viruses are also spread when people gather in crowded indoor places. In such conditions, viruses are quickly passed from one person to another, if the person is infected. 
4. Immunity is also reduced when people experience stress, poor diet, little sleep, or unhealthy habits, making the body more open to infection.

Common Ways Seasonal Viruses Spread and Infect People

These illnesses are mainly spread through direct or indirect contact with infected people.

• Airborne spread is caused when tiny droplets are released by coughing or sneezing. These droplets are breathed in by others.
• Contaminated surfaces also spread viruses. When polluted surfaces such as door handles or personal items are touched, the virus can be transferred to the face.
• Close contact such as shaking hands or sitting near infected people also increases the chance of getting the virus.

How to Protect Yourself from Colds and Viral Infections

1. Good hygiene should be maintained by washing hands often. 
2. Plenty of water should be drunk to keep the body hydrated.
3. A balanced diet should be eaten to support immunity, and proper sleep should be taken. 
4. Crowded places should be avoided during outbreaks. 
5. Vaccines such as the flu vaccine may also be taken after consulting a doctor.

When Medical Help Should Be Taken?

Medical care is needed if fever lasts more than 5 days, breathing becomes difficult, severe headache occurs, rash appears, or vomiting continues.
