<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\nFever is one of the body\u2019s natural defence mechanisms, which signals that something is wrong in our body. Fever can happen due to infection, inflammation, or injury. When fever is caused by a virus, it is called viral fever. Our body raises its temperature as an immune response, which fights the virus in the body ^{1<\/sup><\/a>^,<\/sup>}^{2<\/sup><\/a>.^{<\/sup>For unknown or unexplained fevers, especially short-term fevers, the cause is usually viral}}^{3<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
Fever can be continuous or intermittent and might vary in pattern based on which virus is affecting you. In viral fever, although fever is the main symptom, other symptoms may also be present, depending on the virus. In this blog, we will discuss in detail the causes of viral fever, viral fever symptoms, and its treatment ^{1<\/sup><\/a>^,<\/sup>}^{2<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
<\/span>What Is Viral Fever?<\/strong><\/span><\/h2>\n\n\n\nViral fever is an increase in body temperature caused by a virus entering our body. Viruses are extremely tiny microbes that can\u2019t grow by themselves, so they enter living cells in our body and start replicating ^{2<\/sup><\/a>^,<\/sup>}^{4<\/sup><\/a>^,<\/sup>}^{5<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
Once the virus multiplies inside the cells, it releases substances that can harm the body and cause illness. Our immune system works to fight this virus by sending immune cells called macrophages to attack the virus and release certain proteins to stop the virus\u2019s activity. This triggers an increase in body temperature, causing fever. The high temperature makes it hard for the virus to grow and helps the body fight the infection ^{5<\/sup><\/a>^,<\/sup>}^{6<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
A person is said to have a fever if their oral temperature is above 37.2\u00b0C in the early morning, or above 37.7\u00b0C at any time during the day ^{1<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
Fever is a common symptom in viral infections, with its severity varying by virus type and individual response. In the next section, we will see the different types of viruses causing different types of viral fever ^{6<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
<\/span>Types of Viral Fever<\/strong><\/span><\/h2>\n\n\n\n
$\"types$ <\/figure><\/div>\n\n\n
Viral fevers can be caused by viruses from different families and can spread in many different ways, e.g., through the air, insect bites, contact with infected people, or contaminated water. Each type of virus can cause a different kind of illness in the body ^{7<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
The most common types of viral fever are:\u00a0<\/p>\n\n\n\n
\n
Flu:<\/strong> The influenza virus is responsible for flu and is the most common cause of viral fever. It affects the upper parts of the respiratory system (e.g., the nose and throat). It spreads through the air and causes fever, cough, sore throat, runny nose, and body pain. Sometimes, it can become severe and lead to a lung infection^{8<\/sup><\/a>.\u00a0<\/li>\n\n\n\n}
Dengue: <\/strong>It is caused by a virus belonging to the Flavivirus family. When a mosquito is infected with this virus, it can transmit the virus to a human being through a bite. The dengue virus then enters the human body, multiplies, and enters the blood, causing fever and body pain. In some cases, it can become severe, leading to bleeding, shock, and even death^{9<\/sup><\/a>.\u00a0<\/li>\n\n\n\n}
COVID-19<\/strong>: It is an infection caused by severe acute respiratory syndrome Coronavirus 2. It spreads easily through droplets emitted while talking, coughing, or sneezing. It can cause flu-like symptoms, but in some cases, it can become severe and lead to breathing difficulty and lung damage^{10<\/sup><\/a>.\u00a0<\/li>\n\n\n\n}
Chikungunya fever<\/strong>: Chikungunya fever is caused by the Chikungunya virus. It spreads through the bite of an Aedes mosquito infected with the virus. The illness can cause symptoms like fever, skin rash, and severe joint pain. In some people, the joint pain and swelling can last for weeks or months^{11<\/sup><\/a>.\u00a0<\/li>\n\n\n\n}
Hepatitis<\/strong>: When viruses like hepatitis A and hepatitis E enter your body through contaminated food or water, they can affect your liver. The symptoms usually start with fever, and the eyes and skin may turn yellowish. Most people recover within weeks, but in some cases, it can become severe and lead to liver failure^{12<\/sup><\/a>.\u00a0<\/li>\n<\/ul>\n\n\n\n}
Viral fevers may also affect the stomach (e.g., rotavirus), eyes (e.g., adenovirus), skin (e.g., measles virus), or even the brain (like Japanese encephalitis), causing different viral fever symptoms based on the type and severity of the infection ^{7<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
These viral fevers spread in different ways depending on the virus, which brings us to the next part \u2013 how are viral fevers transmitted?\u00a0<\/p>\n\n\n\n
