What is human coronavirus?

Human coronavirus HKU1 is also known as Betacoronavirus hongkonense. It is a species of coronavirus that can affect both humans and animals.

There are several types of humar coronavirus. Some of these include 229E, NL63, OC43, and HKU1. These variants usually cause mild to moderate upper-respiratory tract illnesses, like the common cold.

It is not same as Covid-19. Common human coronaviruses should not be confused with Coronavirus Disease-2019. It is less severe than the SARS-CoV-2 virus, which causes Covid-19.

"There is no reason to panic. HCoV-HKU1 causes milder infection than SARS & MERS virus. Most patients will have flu like symptoms with runny nose, sore throat, body aches, headache and fever," says Dr. Monica Mahajan, Director - Internal Medicine, Max Healthcare

What are the symptoms of HKU1?

According to CDC and NIH, symptoms of HKU1 include:

• Runny nose
• Fever
• Coughing
• Wheezing
• Headache
• Sore throat

In HKU1, symptoms are usually mild. However, in some cases, especially when left untreated, human coronavirus can result in bronchiolitis and pneumonia.

Transmission of human coronavirus

Common human coronaviruses usually spread from infected individual by coughing, sneezing, close contact or by touching contaminated surfaces.

"Infants, young children and senior citizens are more vulnerable to complications. People with low immunity like diabetics, cancer patients and those with lung disease are more prone to severe disease. It spreads from person to person by respiratory droplets due to coughing and sneezing," Dr. Mahajan adds.

How to stay safe

There is no vaccine or specific treatment for human coronaviruses. Most infected individuals get better on their own. However, it is best to see your doctor if you do not feel better within a few days or if your symptoms continue to get worse.

"Currently, there is no vaccine for HKU-1. Basic cough etiquettes while coughing and sneezing, avoiding contact with a patient with flu like illnesses and a healthy diet consumption is all that needs to be followed," advises Dr. Mahajan.

Human coronavirus HKU1 (Hong Kong University) was first discovered in 2004.
