HMPV Virus in China: Reports indicate that China is currently grappling with an increase in cases of a respiratory illness known as human metapneumovirus (HMPV). Social media posts suggest that hospitals in the country are overwhelmed. The virus primarily impacts the elderly and children, but it can cause upper and lower respiratory diseases in people of all ages.
As winter takes hold, China is facing a surge in respiratory illnesses, particularly human metapneumovirus (HMPV). This outbreak occurs five years after the devastating COVID-19 pandemic, with reports indicating that hospitals and crematories are overwhelmed by the increasing number of cases. Social media and online videos show overcrowded medical facilities, with some users stating that multiple viruses, such as HMPV, influenza A, Mycoplasma pneumoniae, and even COVID-19, are spreading concurrently.
HMPV virus surge in China
There is considerable online chatter about a ‘new epidemic’ emerging in China, with some posts alleging that the country is concealing the true scope of the situation. Although there is an increase in respiratory illnesses in China, neither the Chinese government nor the World Health Organization (WHO) has released any formal advisories, alerts, or declared a state of emergency.
Reports suggest that the rise in HMPV cases has caused a concerning increase in sudden deaths, particularly impacting those aged 40 to 80. A post by the SARS-CoV-2 (COVID-19) account on social media platform X stated, “China is experiencing a surge in various viruses, including Influenza A, HMPV, Mycoplasma pneumoniae, and COVID-19, which are overwhelming hospitals and crematoriums. Children’s hospitals are especially strained by the increase in pneumonia and ‘white lung’ cases.”
According to official sources cited by news agency ANI, the National Centre for Disease Control (NCDC) under the Union Health Ministry is closely monitoring cases of respiratory and seasonal influenza in the country and is in contact with international agencies. “We will continue to closely monitor the situation, verify information, and provide updates as needed,” said the sources.
Is there really an epidemic?
Some users on X have shared videos of crowded hospitals, speculating that China’s healthcare system is overwhelmed by a “new virus outbreak.” However, there is no credible evidence to substantiate these claims. Neither Chinese health authorities nor the WHO have issued any official statements confirming such a crisis.
In reality, while both flu and HMPV contribute to respiratory infections, influenza A remains the leading cause of illness this winter. Although there are increased cases of HMPV, it remains a localized issue with no indications of reaching pandemic levels. It’s important to note that HMPV isn’t new—it was first identified in 2001 and typically causes seasonal outbreaks, as reported by TOI.
What are the symptoms of HMPV?
The US Centers for Disease Control and Prevention (CDC) notes that common symptoms of HMPV include cough, fever, nasal congestion, and shortness of breath.
Li Tongzeng, a chief doctor in the Department of Respiratory and Infectious Diseases at Beijing You’an Hospital, Capital Medical University, explained that HMPV can be transmitted via respiratory droplets, direct contact between individuals, such as handshakes, or by touching objects contaminated with the virus, as reported by CCTV. The incubation period for the virus is typically three to five days.
What is the most affected age group?
Discovered in 2001, HMPV belongs to the Pneumoviridae family alongside the Respiratory syncytial virus (RSV). However, serological studies indicate that it has been present in humans for over 60 years and is found worldwide.
This virus can cause both upper and lower respiratory illnesses in individuals of all ages, but it primarily affects young children, older adults, and those with weakened immune systems.
HMPV, capable of infecting individuals of all ages, is most prevalent in children, heightening public health concerns. The rise in cases is impacting both kids and older adults. Young children, with their not yet fully developed immune systems, are especially vulnerable. The elderly, along with those who have conditions such as asthma or COPD, face a heightened risk of severe complications.
People with weakened immune systems or chronic respiratory issues are also more susceptible to complications. The virus spreads through droplets expelled when an infected person coughs or sneezes, making crowded places particularly high-risk for transmission.
What is driving the surge?
Experts suggest that the increase in respiratory cases, including HMPV, is primarily due to cold weather and the return to normal life post-COVID. For several years, strict lockdowns and reduced social interactions kept many viruses at bay, resulting in less exposure to common pathogens, particularly among children. With the world reopening, there is a “catch-up” period as people are re-exposed to these viruses, significantly affecting children and vulnerable adults.
How does it spread?
The virus is most likely to spread from an infected person to others through:
- Secretions from coughing and sneezing.
- Close personal contact, such as touching or shaking hands.
- Touching objects or surfaces contaminated with the virus, then touching one’s mouth, nose, or eyes.
According to the CDC, HMPV circulates in specific seasonal patterns, typically starting in winter and continuing until or through the spring.
HMPV virus prevention tips
To minimize the risk of HMPV and other respiratory illnesses, the CDC advises the following measures:
- Regularly wash hands with soap and water for at least 20 seconds.
- Avoid touching your face with unwashed hands.
- Wear masks in crowded places during outbreaks.
- Stay home when sick to prevent spreading the virus.
- Frequently clean surfaces that are often touched.
This outbreak has increased awareness of the importance of preventive actions, especially since there is no vaccine for HMPV, despite its existence being known for nearly two decades. Authorities across Asia are closely monitoring the flu outbreak and the spread of respiratory viruses in China, while surrounding regions are implementing stringent surveillance measures. In Hong Kong, for instance, very few cases have been reported.
HMPV: A Respiratory Illness You Need to Know About
HMPV, or human metapneumovirus, is a virus responsible for respiratory infections, especially affecting young children, the elderly, and individuals with weakened immune systems. Here are the essentials about HMPV, including its symptoms, prevention, and treatment methods.
What is HMPV?
Human metapneumovirus (HMPV) spreads from person to person through close contact. While its symptoms usually resemble those of a common cold, they can be more severe for certain populations. HMPV was discovered by Dutch scientists in 2001.
Most individuals become infected with HMPV before the age of five, and it can recur throughout a person’s life. HMPV infections often occur during winter and early spring, coinciding with flu season. Research indicates that HMPV accounts for 10% to 12% of pediatric respiratory illnesses. While most cases are mild, between 5% and 16% of children may develop a pneumonia-like infection of the lower respiratory tract, according to the Cleveland Clinic.
Symptoms of HMPV
HMPV symptoms often include cough, fever, nasal congestion, and shortness of breath. The clinical signs resemble those of other viruses that cause upper and lower respiratory infections and can progress to bronchitis or pneumonia. The estimated incubation period ranges from 3 to 6 days, and the median duration of illness can vary depending on the infection’s severity, though it is similar to other viral respiratory illnesses, according to the Centers for Disease Control and Prevention.
Diagnosis of HMPV
Healthcare providers may not routinely consider or test for HMPV, as it is a relatively recent discovery among respiratory viruses. However, when there is widespread circulation of HMPV, healthcare professionals are more likely to consider testing for it.
To diagnose a respiratory infection, your doctor will conduct a physical examination and review your medical history. To more definitively identify HMPV as the cause, your doctor may order lab tests to determine the specific virus causing your illness, according to the American Lung Association.
Prevention and Treatment of HMPV
Currently, there is no vaccine or specific antiviral treatment available for HMPV. To prevent the spread of HMPV and other respiratory viruses like COVID-19, colds, and the flu, consider the following measures:
- Wash your hands with soap and water for at least 20 seconds.
- Avoid touching your mouth, nose, or eyes with unwashed hands.
- Keep a safe distance from individuals who are ill.
- If you exhibit cold-like symptoms, cover your mouth and nose when coughing or sneezing, wash your hands frequently and thoroughly, avoid sharing cups or dining utensils, refrain from kissing others, and stay home if you are unwell.
- Regularly sanitize potentially contaminated surfaces, such as doorknobs and shared toys, to help prevent the spread of HMPV.
HMPV is a respiratory illness that can cause symptoms ranging from mild to severe. Maintaining good hygiene practices and staying home when sick are vital in preventing the virus’s spread. For most people with mild HMPV symptoms, supportive care at home is sufficient, and the illness typically resolves on its own. However, if you or someone you know experiences symptoms of HMPV, it is important to seek medical attention promptly.
