How do viral infections get identified?

After listening to your symptoms and examining you, a healthcare provider will most likely diagnose you with a viral infection. To diagnose a specific virus, your provider may swab your nose or throat or take a blood sample.

If your doctor suspects you have a viral infection causing severe inflammation in your lungs, brain, or another internal organ, he or she may order X-rays, ultrasounds, MRIs, or CT scans. Imaging cannot determine whether you have a viral infection, but it can assist your doctor in determining how it is affecting your body.

What drugs are used to treat viruses?

To treat viral infections, your doctor may prescribe antiviral medications such as Paxzen and Primovir.

Paxzen Tablet (Nirmatrelvir Ritonavir)

Paxzen Tablet is best suited for people who are experiencing mild viral symptoms but are at high risk of developing severe disease. Nirmatrelvir, an antiviral medicine, prevents the virus from spreading into the body, and ritonavir, a booster, increases the availability of nirmatrelvir in the body to maximise the effectiveness of this combination medicine. If you want to use this medication, you can get it at

Primovir (Nirmatrelvir Ritonavir) Tablet

It is a well-known antiviral medication used to treat critically ill patients. Nirmatrelvir is the main protease inhibitor for a common viral infection, and it helps viral patients manage their symptoms. When doctors and carers use primovir correctly, it gives you the confidence to live a better life.

What should I do if I have a viral infection?

The type of viral infection determines what to expect. In most cases, less serious infections, such as the common cold or skin infections, can be treated at home. Other viral infections, on the other hand, can be fatal or cause long-term illness.

What is the duration of viral infections?

The duration of viral infections can vary greatly, for example:

  • Respiratory infections can last anywhere between a few days and two weeks.
  • A wart on your skin can last up to a year.
  • Chronic infections caused by Hepatitis B and C can last for years.
  • HIV infections are incurable and permanent.

Viral infection complications

Viral infections can lead to serious complications, both immediately and years later. Among the complications are:

  • Inflammation of the lungs (pneumonia). Respiratory illnesses can infect your lungs, causing swelling and making breathing difficult. If you have severe pneumonia, you may need to be hospitalised.
  • Inflammation of the brain or of its lining (encephalitis or meningitis). Swelling can occur when a virus spreads from another part of your body to your brain. This could be deadly.
  • Significant bleeding. Hemorrhagic illnesses, such as severe dengue fever, can cause fatal bleeding.
  • Reactivation. Some viral infections can live in your body for a long time even if you have no symptoms or never had any symptoms at all. A dormant virus is one that is not reproducing in your body or causing symptoms. Viruses such as Epstein-Barr virus (EBV), human papillomavirus (HPV), herpes simplex virus (HSV), and varicella can reactivate in your body years later and cause symptoms.
  • Cancer. Some viruses, if left in your body for an extended period of time, can cause cancer. HPV, Epstein-Barr virus, HIV, hepatitis B and C, human T-lymphotropic virus 1 (HTLV-1) and human herpesvirus 8 have all been linked to specific cancers.

When should I make an appointment with my doctor?

Contact a healthcare provider if:

  • Consult your doctor if your symptoms of a viral infection do not improve or worsen after several days.
  • You have the flu or viral infection symptoms and are at risk of becoming seriously ill. Your doctor may prescribe antiviral medications.
  • You’ve been infected with HIV, rabies, hepatitis B, or chickenpox. As soon as possible after exposure, post-exposure prophylaxis is required.

When should I go to the emergency room?

If you have any of these signs of a serious infection, you should go to the nearest ER or get medical help right away:

  • fever of 103 degrees Fahrenheit or 39.4 degrees Celsius.
  • It’s difficult to breathe.
  • Chest ache.
  • I’m coughing up blood.
  • severe abdominal (stomach) pain.
  • Confusion or other mental changes are possible.

What questions should I ask my doctor?

  • How can I keep this from spreading to others?
  • How should I take my medication?
  • How long will it take to recover?
  • What can I do at home to manage my symptoms?
  • When should I contact you again?

A message from the Cleveland Clinic

Most viral infections are not dangerous. On a regular basis, we deal with colds, stomach bugs, and skin bumps and sores. Some viruses, however, cause life-threatening illnesses, and some common illnesses, such as the flu, can be deadly. This is why protecting yourself and those around you from a viral infection is critical. Vaccinations, proper hand-washing habits, and safe sexual practises can all help you stay healthy.
