Symptoms, Causes, and Foods to avoid in Viral Fever

Updated on 21 July 2022

The collective term for fever that originates from different viral infections is known as viral fever. Typically, the temperature of a human body is around 37.1°C or 98.4°F. If the temperature goes above this value, one would have a fever. In some infections, viral fever tends to be a lower grade (<100°F) whereas, in others like dengue, it tends to be a higher grade (>100°F). 

Generally, symptoms of viral fever are acute and occur more commonly during seasonal changes. In the case of most viral infections, viral fever lasts for 3 to 5 days. However, in severe cases, it may last for up to 2 weeks. Viral fever itself isn’t a disease or an illness. It is more a sign of the viral infection persistent in the body. Individuals having weak immune systems, kids, and older people are more prone to viral fevers.

What Causes Viral Fever?

The body produces pyrogens as a defence mechanism against viral antigens, which is what actually causes viral fever. Here are some causes to consider. 

  • When you come in close contact with a host (someone who has an active viral infection) or a carrier can result in the transmission of viral fever from one person to another. Keep in mind that someone who is not experiencing any symptoms of the viral fever could be carrying the virus, and can infect others.

  • The consumption of contaminated water can also cause viral fever.

  • The mini droplets of cough from an infected person can cause viral fever when inhaled.

  • It can also get transmitted by sharing drinks or food with an infected person.

  • Seasonal Flu is the highest contributor to causing Viral Fever.

  • Viral infections also get transmitted by insects and animals. For example, Chikungunya, dengue, Zika virus, and yellow fever are viral infections that get spread due to insects and animals.

Do’s for Fighting a Viral Fever

  • Take medication for viral fever as your doctor has prescribed - It is best to avoid self-medicating if you have a viral fever. You should consult your critical care doctor in Hyderabad and take medication as per their prescription. This is because you might have a fever due to a bacterial infection, in which case, you might need a different medication.

  • Get plenty of rest so that your body can fight the fever and help you get better sooner - If you don’t get enough rest, your body won’t be able to cope with the stress and you won’t get better sooner. If you continue with your normal routine, it can hamper your body’s attempt to fight the fever. Also, when you have a fever, you tend to get tired anyway, which is why adequate rest is a must.

  • Keep your body cool by applying a cloth to your forehead with lukewarm water or taking a sponge bath. This will help bring down the temperature of your body and help it cool down. This is necessary because the body temperature is high when you have a fever and it is important to bring it down.

  • Stay hydrated. Try to consume as many fluids as possible so that your body doesn’t become dehydrated and there are certain foods to avoid in viral fever. When you have a fever, your body tends to lose fluids easily, causing dehydration. Hence, it is important to increase the intake of fluids. You can also drink diluted juice, or clear soup if you find water boring. 

Don’ts of Fighting a Viral Fever

  • Avoid consuming caffeinated beverages, soda and alcohol if you have a fever as these beverages can cause dehydration, whereas it is important to stay hydrated if you have a fever.

  • Try to avoid covering your body in too many layers, unless you are feeling cold or shivering, as this might raise your body temperature. The aim is to bring the body’s temperature down and if you wear too many layers or stay covered in a blanket, the temperature might go up. 

  • Don’t starve yourself as your body needs nutrition and energy to fight off the fever and help you feel better. If you starve yourself, your immune system can become even weaker, since your metabolism increases due to a fever.

  • Don’t deprive yourself of sleep. When you have a fever, your immune system consumes a lot of energy, as it is trying to fight off the fever. Hence, it is recommended to get 7 to 9 hours of sleep each night, so that you get enough rest as well as time to heal.

  • Avoid sharing your utensils, clothes, handkerchiefs, towels and other personal items as it might spread the infection to others who may come in contact with you. If anyone comes in contact with you or your items, they can also get infected as viral infections are contagious. Hence, it is best to stay in a separate room and have separate utensils and other items that no one else will use.
