Kolkata Woman Diagnosed With Human Coronavirus: What Is It, Causes, Symptoms, And Treatment

A 49-year-old woman from Kolkata, West Bengal, was recently diagnosed with human coronavirus HKU1, a lesser-known strain of the virus that affects the respiratory system. She was admitted to RN Tagore Hospital after suffering from a persistent fever for 15 days. Dr Arindam Biswas, the treating physician, confirmed that while she initially showed signs of secondary pneumonia, further testing identified the HKU1 strain. "There is no travel history for the patient. This is not related to SARS-CoV-2, but it is another strain of coronavirus, HKU1," he stated. The woman is currently stable and responding well to treatment. Human coronavirus HKU1 is different from COVID-19 and is usually associated with common cold-like symptoms. However, it can become severe in individuals with weak immunity. We spoke to Dr Harish Chafle, Senior Consultant Intensivist, Chest Physician, Bronchoscopist, and Sleep Disorders Specialist at Gleneagles Hospital, Parel, Mumbai, to learn more about the virus. Here’s everything you need to know about this virus, its symptoms, causes, and treatment.

What Is Human Coronavirus?

Human coronavirus HKU1 is a respiratory virus that primarily affects the lungs and airways. It was first identified in 2005 and is one of several coronaviruses that cause mild to moderate respiratory infections. It spreads through direct contact with an infected person, respiratory droplets from coughing or sneezing, or touching contaminated surfaces. Dr Chafle warns, "People with weakened immunity, such as the elderly and those with pre-existing conditions, are at a higher risk of severe complications."

What Are The Symptoms Of Human Coronavirus?

The symptoms of HCoV-HKU1 are quite similar to those of the common cold or flu. They include:

1. Fever
2. Cough
3. Runny nose
4. Sore throat
5. Chest pain
6. Difficulty breathing
7. Fatigue
8. Pneumonia in severe cases

Dr Biswas notes, "Severe infections are more common in adults or those with weaker immunity." While many people recover within a few days, the virus can lead to serious respiratory issues in individuals with underlying health conditions.

What Are The Causes Of Human Coronavirus?

The human coronavirus spreads mainly through:

• Close contact with an infected person
• Inhaling respiratory droplets from coughing or sneezing
• Touching contaminated surfaces and then touching the face
• Poor hygiene and crowded places
• Cold weather can also increase the risk of infection.

Dr Chafle emphasises, "Frequent hand washing and avoiding contact with infected individuals are key preventive measures."

Treatment Of Human Coronavirus

Currently, there is no specific antiviral treatment for HCoV-HKU1. Most people recover with rest, hydration, and over-the-counter medicines for symptom relief. In severe cases, hospitalisation may be required for oxygen support or additional care.

Doctors recommend to do the following if you’re diagnosed:

• Drinking plenty of fluids
• Getting enough rest
• Taking fever-reducing medications (only as prescribed by a doctor)
• Maintaining good hygiene to prevent further spread
