Any ailment caused by a virus, a microscopic microbe that reproduces by using your cells, is referred to as a viral infection. Colds, the flu, COVID-19, norovirus (or “stomach flu”), HPV (warts), and herpes simplex virus (cold sores) are examples of common viral infections. While many viruses disappear on their own, some can lead to serious or long-lasting illnesses.

Consult your physician if you experience symptoms that persist for more than a few days or that worry you.

Why do viral infections occur?
Only a small number of the many viral types that can cause diseases can infect people. They can enter your body through a skin break, your mouth, nose, eyes, anus, or genitalia. Once there, they enter your cells and utilize them to multiply by duplicating themselves.
How are viral infections diagnosed?
By paying attention to your symptoms and physically inspecting you, a doctor may frequently determine that you have a viral illness. Your healthcare professional may swab your nose or throat or draw blood to test for a specific virus.
Your healthcare practitioner may order X-rays, ultrasound, MRI, or CT imaging if they believe you have a viral infection that is seriously causing inflammation in your lungs, brain, or another internal organ. A viral illness cannot be diagnosed by imaging, but it can help your doctor understand how it is impacting your body.
What is the treatment for viral infections?
Only a few viral infections can be treated with particular drugs. A doctor may recommend antiviral drugs or other treatments for viruses that can lead to life-threatening or persistent sickness so you don’t get sick after being exposed to a virus.
You can usually treat the symptoms of infections like the common cold at home while you wait for them to go away on their own because they rarely cause serious illness.
The majority of viral infections are not dangerous. We regularly deal with colds, the occasional stomach virus, and rashes and blisters on our skin. Other common infections, like the flu, can worsen and some viruses can even be fatal. This is why it’s so important to take precautions to stop yourself and others from contracting viruses. You can maintain excellent health by getting vaccinations, cleaning your hands frequently, and engaging in safe sexual activity.
