Preventing, Diagnosing, and Treating Postpartum Haemorrhage: A Practical Summary of WHO 2025 Recommendations Introduction Postpartum haemorrhage (PPH) remains the leading cause of maternal mortality globally , accounting for nearly one in five maternal deaths worldwide. The majority of these deaths are preventable through timely prevention, early diagnosis, and standardised treatment. Recognising persistent gaps in care, the World Health Organisation (WHO), in collaboration with the International Federation of Gynaecology and Obstetrics (FIGO) and the International Confederation of Midwives (ICM), released consolidated evidence-based guidelines in 2025 to harmonise global practice and accelerate reductions in maternal deaths. This article summarises the key recommendations for the prevention, diagnosis, and treatment of postpartum haemorrhage , translating the guideline table into practical guidance for frontline health workers and health ...
Human Metapneumovirus (HMPV): Everything You Need to Know
Human Metapneumovirus (HMPV) is a respiratory virus that often flies under the radar but poses significant health risks, especially to vulnerable populations. Whether you're a parent concerned about your child's health or someone curious about public health issues, understanding HMPV is crucial.
What is Human Metapneumovirus?
Origins and Discovery
Discovered in 2001, Human Metapneumovirus belongs to the Paramyxoviridae family, which includes viruses like respiratory syncytial virus (RSV). Scientists believe HMPV has been circulating in humans for decades, likely evolving from an ancestral avian virus.
Comparison with Other Respiratory Viruses
HMPV shares similarities with RSV and influenza, such as causing respiratory tract infections. However, it is distinct in its genetic makeup and can often be misdiagnosed due to overlapping symptoms.
How Does HMPV Spread?
Modes of Transmission
HMPV spreads through respiratory droplets when an infected person coughs or sneezes. It can also survive on surfaces, making contaminated hands and objects a significant transmission route.
Risk Factors for Infection
Children, the elderly, and individuals with weakened immune systems are particularly susceptible. Crowded places like daycare centers and hospitals often become hotspots for outbreaks.
Symptoms of HMPV Infection
Early Signs of HMPV
Symptoms of HMPV often resemble a common cold and include runny nose, cough, and fever. These signs may go unnoticed, leading to delayed diagnosis.
Severe Cases and Complications
In severe cases, HMPV can cause bronchiolitis or pneumonia, especially in high-risk groups. If breathing difficulties arise, hospitalization may be required.
Diagnosing HMPV
Common Diagnostic Methods
HMPV diagnosis typically involves a nasal swab or throat culture to detect the virus's genetic material. Blood tests may also be used to rule out other infections.
Why Early Diagnosis Matters
Identifying HMPV early can prevent complications and guide appropriate treatment. Misdiagnosis often leads to ineffective treatments, worsening patient outcomes.
Prevention and Treatment of HMPV
Human Metapneumovirus (HMPV) lacks a specific antiviral treatment, making prevention and supportive care essential in managing its spread and impact. Let’s explore ways to prevent infection and the available treatment options.
Preventative Measures
Hygiene and Sanitation Practices
Good hygiene practices are your first line of defense against HMPV. Regular handwashing with soap and water, especially after coming into contact with public surfaces or sick individuals, can significantly reduce the risk of infection. Disinfecting high-touch surfaces, such as door handles and mobile devices, is also crucial.
Cough etiquette plays an equally vital role. Encourage covering coughs and sneezes with a tissue or the elbow to minimize airborne spread. For young children, teaching these habits early helps protect them and those around them.
Vaccines: Are They Available?
Currently, there is no approved vaccine for HMPV, although research is underway. Scientists are investigating potential candidates, with some in preclinical and early clinical trial phases. Until a vaccine becomes widely available, the focus remains on public awareness and adherence to preventative strategies.
Treatment Options for HMPV
Medications and Supportive Care
Management primarily involves supportive care since there is no specific antiviral treatment for HMPV. Over-the-counter medications like acetaminophen or ibuprofen help alleviate fever and pain. Decongestants and saline nasal sprays may provide relief from nasal congestion.
In severe cases, hospitalization might be necessary. Patients with breathing difficulties could require supplemental oxygen or mechanical ventilation. Intravenous fluids may be administered to prevent dehydration.
At-Home Care for Mild Infections
Most HMPV infections are mild and can be managed at home with rest, hydration, and symptom relief. Consuming warm fluids, such as soup or herbal teas, can soothe the throat and alleviate coughing. A humidifier may help ease respiratory symptoms, especially in children and the elderly.
The Global Impact of HMPV
Human Metapneumovirus may not grab as many headlines as influenza or RSV, but its global impact is undeniable. Understanding its prevalence and the populations most affected is key to addressing its health burden.
Epidemiology and Prevalence
Global Statistics
HMPV is a leading cause of acute respiratory infections worldwide. It accounts for a significant percentage of hospitalizations due to lower respiratory tract infections, particularly in children under five years old. Outbreaks typically peak during late winter and spring, similar to RSV.
Seasonal Patterns of HMPV
Like other respiratory viruses, HMPV exhibits seasonal trends. In temperate regions, cases surge during colder months, when people spend more time indoors. Understanding these patterns helps public health officials predict and prepare for outbreaks.
Vulnerable Populations
Children and the Elderly
Young children, especially infants, are the most vulnerable to HMPV, often experiencing severe symptoms that require medical attention. Similarly, older adults, particularly those with underlying health conditions like COPD or heart disease, are at heightened risk of complications.
Immunocompromised Individuals
People with weakened immune systems, such as those undergoing chemotherapy or living with HIV, face increased risks from HMPV. For these populations, infections can rapidly progress to severe respiratory distress, necessitating prompt medical care.
Research and Future Directions
As the global community continues to combat respiratory illnesses, research on HMPV is gaining momentum. Innovations in diagnostics, vaccines, and treatment hold promise for reducing its burden.
Ongoing Studies on HMPV
Challenges in Vaccine Development
Developing a vaccine for HMPV presents unique challenges, including the virus's genetic diversity and the complexity of eliciting long-lasting immunity. Researchers are leveraging insights from RSV vaccine development to overcome these hurdles.
Promising Advances in Treatment
New antiviral drugs targeting HMPV are in early testing phases. Monoclonal antibody therapies, already used for RSV, are being explored as potential treatments for severe HMPV cases. These advancements could revolutionize care for high-risk groups.
Public Health Implications
Educating the Public About HMPV
Public awareness campaigns emphasizing hygiene, symptom recognition, and the importance of seeking timely medical care are crucial. Knowledge empowers individuals to protect themselves and their communities.
Strengthening Healthcare Systems
Healthcare systems must adapt to manage HMPV effectively, particularly during seasonal peaks. Investing in diagnostic tools, hospital resources, and training for healthcare professionals can mitigate the virus's impact.
Conclusion
Human Metapneumovirus may not be as well-known as other respiratory viruses, but its effects on public health are significant. Understanding its symptoms, prevention strategies, and global impact can help reduce the burden of this virus. Continued research and public health efforts are essential to combating HMPV and protecting vulnerable populations.
