A woman from Kolkata has been diagnosed with the human coronavirus HKU1 (HCoV-HKU1), a strain of coronavirus that primarily causes mild respiratory infections. The 49-year-old woman, who hails from South Kolkata’s Garia area, had been battling a persistent fever for 15 days before being admitted to RN Tagore Hospital. Despite receiving treatment, she has no travel history within the past 30 days. Her condition is currently stable, and doctors are optimistic about her recovery, with an expected discharge soon.
HCoV-HKU1, first identified in 2005, is part of the larger coronavirus family, which also includes SARS and MERS, though it is much less severe. Unlike COVID-19, which was a novel virus at the time of its outbreak, HKU1 has been evolving in humans for several years. Dr. Suranjit Chatterjee, a senior consultant, explains that HKU1 is not a new virus and has been a known cause of mild illnesses like the common cold and flu. “Most people are exposed to these viruses at some point in their lives,” he said, adding that the virus causes temporary infections that usually resolve on their own.
Symptoms of HKU1
Common symptoms of HKU1 include fever, sore throat, nasal congestion, headache, runny nose, and fatigue, similar to regular flu-like symptoms. In rare instances, it can lead to more severe conditions such as pneumonia or bronchitis. While most cases are mild, vulnerable groups such as children, the elderly, pregnant women, and those with weakened immune systems may experience more severe effects.
The virus is transmitted through respiratory droplets from coughing or sneezing, and can also spread by contact with contaminated surfaces. Experts suggest simple preventive measures such as frequent hand washing, wearing masks in crowded places, and avoiding contact with infected individuals to limit transmission.
No Vaccination Available for HKU1
Currently, there is no vaccine for HKU1, and treatment primarily focuses on managing symptoms. As the world remains vigilant against new viral threats, HKU1 serves as a reminder of the ongoing need for basic hygiene practices and awareness to combat respiratory infections.
