An offseason or a time-out period is generally a time that's meant for relaxation, but the number of three kinds of contagious conditions, videlicet Dengue, Flu, and Viral Fever in Winter, has been doubled. These ailments also share some parallels in their symptoms, for instance, fever, body aches, and fatigue, and hence they're frequently confused with each other. Still, these conditions vary in their causes, treatments, and prevention styles. First, we will bandy these conditions, their differences, how they spread, and what steps you can take to be safe in the stormy and cold rainfall.

Viral​‍​‌‍​‍‌​‍​‌‍​‍‌ Fever is a common term that is used for several fevers caused by viruses. It is very typical during the cold seasons when the immune system may not be so strong, and people are more likely to stay indoors. Along with that, the patient may experience aching in the body, shivering, and, at times, also breathing ​‍​‌‍​‍‌​‍​‌‍​‍‌problems.

3. Treatment: Bringing down the fever by use of medication, drinking a lot of water, and ​‍​‌‍​‍‌​‍​‌‍​‍‌resting.

Detailed Understanding of Dengue

Dengue fever is a viral infection caused by Aedes mosquitoes. It is a disease of the tropics, but it can be spread to urban areas during the cold season.

Symptoms of Dengue:-

They include high temperature or fever that is sudden in nature, extremely painful headache, pain in the eyes, pain in joints and muscles, skin rash and bleeding of a mild nature, weakness, and fatigue.
