A 45-year-old woman from Garia, Kolkata, has been confirmed as the first case of human coronavirus HKU1 (HCoV-HKU1) in the area, receiving medical attention at a private hospital in South Kolkata. For the past 15 days, she has been battling a persistent fever, cough, and cold, but hospital officials have reported that her condition remains stable. Though this virus isn’t as notorious as COVID-19, it still poses risks and requires public awareness regarding symptoms and potential complications.

What Exactly Is Human Coronavirus HKU1?

Human coronavirus HKU1 (HCoV-HKU1) is part of the Betacoronavirus family, which includes harmful strains like SARS and MERS. Unlike the severe consequences of SARS-CoV-2, the virus responsible for COVID-19, HKU1 typically leads to milder respiratory issues. It mainly targets the upper respiratory tract and can induce symptoms akin to the common cold; however, it is capable of escalating into more serious conditions such as pneumonia or bronchiolitis.

Symptoms: What to Watch Out For

The majority of HCoV-HKU1 cases mimic typical flu-like illnesses, which include:

- Fever

- Cough

- Runny or stuffy nose

- Sore throat

- Fatigue

While mild cases often resolve naturally, vulnerable groups—such as the elderly, young children, and those with compromised immune systems—may experience severe complications.

Who Is Most at Risk?

Although human coronavirus HKU1 isn’t as broadly recognized as COVID-19, certain demographics are more susceptible to its effects:

- Elderly individuals

- Infants and young children

- Those with weakened immune systems or chronic health conditions

In healthy adults, the HCoV-HKU1 generally results in mild symptoms similar to a common cold, but for those with weakened defenses, hospitalization may be necessary if the infection progresses to more severe respiratory issues.

How Does It Spread?

Similar to other respiratory viruses, human coronavirus HKU1 transmits through:

- Coughing and sneezing

- Close contact with an infected individual

- Touching contaminated surfaces and then touching the face

Protect Yourself from Infection

Currently, there is no specific vaccine or antiviral treatment for human coronavirus HKU1. Nevertheless, practicing fundamental hygiene and health precautions can mitigate the risk of infection:

- Wash your hands often with soap and water for at least 20 seconds.

- Use a mask in crowded or at-risk environments.

- Maintain social distance from individuals exhibiting respiratory symptoms.

- Regularly disinfect frequently touched surfaces, such as doorknobs and smartphones.

- Cover your mouth and nose with a tissue or elbow when coughing or sneezing.

- Strengthen your immune system by consuming a nutritious diet, staying hydrated, and ensuring sufficient rest.

Should You Be Concerned?

Medical professionals following the case in Kolkata are keen to reassure the public that this incident is isolated and does not signal a broader outbreak. Although human coronavirus HKU1 has been around for some time, it rarely comes into focus as its symptoms align closely with those of typical seasonal respiratory infections.
