4 early signs of viral infections
A viral infection can seem similar to a bacterial infection because of an overlap in their symptoms. However, viruses are much tinier than bacteria and need a host to survive, making treatment of viral infections differ from bacterial ones. Viruses can cause many diseases by attacking certain cells like those in the respiratory system, liver, and blood. Here are a few early signs of a viral infection that one can observe: Flu symptoms Fever, body aches, headache, and fatigue are some of the telltale signs of a viral infection like influenza. These symptoms can vary from mild to severe and may require immediate treatment. The symptoms here may develop suddenly instead of gradually, so it is important to seek a prompt diagnosis when one observes any of the abovementioned signs. Those with flu symptoms usually recover in less than two weeks, however, some people may experience serious complications like pneumonia. Upper respiratory symptoms Another common type of symptom to recognize is respiratory issues, like persistent sore throat, coughing, nasal congestion, and sneezing. Sinus or ear infections are some of the complications that can develop due to a viral infection. In severe cases, the virus can cause extreme inflammation in the respiratory system, which can lead to sepsis—the body’s extreme response to an infection.
