Legionnaires’ disease first came to public attention in 1976 after an American Legion conference in Philadelphia led to dozens of pneumonia cases caused by a then-unknown bacteria. Scientists later identified it as Legionella, a bacteria that naturally occurs in freshwater but typically remains harmless in small quantities.

Problems arise when stagnant, warm water systems, from cooling towers to pipes, provide fertile ground for the bacteria to multiply and release into the air.

Once inhaled in contaminated mist, the bacteria can cause a dangerous form of pneumonia that kills about one in ten infected patients. The Centers for Disease Control and Prevention (CDC) estimates that most cases in the U.S. are linked to potable water systems.

New York’s Current Outbreak

This summer, New York City has recorded its largest outbreak in years, with more than 100 people sickened and at least five deaths. Officials have traced the source to a cluster of contaminated cooling towers in Central Harlem, including one at Harlem Hospital. Heavy July storms are believed to have filled these towers with rainwater that went untreated, allowing bacteria to spread.

The incident has already triggered lawsuits against contractors and raised questions about whether city inspections are keeping pace with the threat. Just 1,200 cooling towers were inspected in the first half of 2025, a sharp decline from 2017 when more than 5,000 were checked in the same period.

Not Just a New York Problem

While the outbreak has grabbed headlines in New York, public health researchers emphasize this is not an isolated concern. Cases of Legionnaires’ have been climbing steadily across the United States, Canada, and Europe.

The Environmental Protection Agency (EPA) warns that warmer temperatures and increased rainfall are making conditions across the country more favorable for Legionella.

Communities that never needed large-scale cooling systems are now installing them to combat rising heat, creating new risks. Even modern “green” buildings can unintentionally increase exposure. Low-flow plumbing systems, designed to conserve water, can allow it to sit stagnant in pipes, encouraging bacterial growth.

Climate Change Accelerates the Spread

Summers have always been peak season for Legionnaires’, but climate change is intensifying the problem. Warmer air, higher humidity, and extreme rain events are combining to create perfect breeding conditions. Flooding adds another complication, as contaminated water can more easily infiltrate public water supplies.

European health agencies have already warned that climate change is likely to expand the range of Legionnaires’ disease. In the United States, rising cases mirror these predictions, suggesting the New York outbreak may be just one of many to come.

Unequal Burden on Vulnerable Communities

As with many climate-linked health threats, low-income neighborhoods often suffer most. Poorly maintained cooling towers are more likely in underfunded housing complexes, and chronic health issues common in these areas, such as asthma or diabetes, make residents more vulnerable to severe illness.

Harlem, the center of New York’s outbreak, highlights this intersection of infrastructure neglect and health inequality. Experts caution that without stronger oversight and better maintenance of public systems, similar communities nationwide could become hotspots for future outbreaks.

What Individuals Can Do

For most people, preventing Legionnaires’ on an individual level is difficult, since the bacteria spreads through community water systems and airborne mist. Still, health officials advise paying attention to public health alerts, especially if you are over 50, smoke, or have chronic conditions that weaken the lungs or immune system.

During outbreaks, residents can consider using high-quality water filters or ensuring home cooling systems are regularly cleaned. But the most critical step remains recognizing symptoms early. Fever, cough, and shortness of breath should prompt immediate medical attention, as antibiotics are highly effective when treatment begins quickly.

A Public Health Responsibility

Experts stress that Legionnaires’ disease cannot be managed through individual vigilance alone. The real solution lies in better maintenance of large-scale water and cooling systems, more consistent inspections, and infrastructure upgrades that account for a warming world.

Sick days are again piling up with a respiratory disease, not COVID-19 or the flu. This disease is most likely the one Americans have not heard of. This is HMPV or human metapneumovirus. Doctors have asked people to stay vigilant as seasonal flu virus could lead to pneumonia and bronchitis, and it is spreading in California wastewater and around the country. However, as per public health officials, there is nothing to get worried at this point.

As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.

The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.

Virus Without A Vaccine: What Is HMPV?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).

HMPV most likely spreads from an infected person to others through:

• the air by coughing and sneezing
• close personal contact, such as touching or shaking hands
• touching objects or surfaces that have the viruses on them, then touching the mouth, nose, or eyes

In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.

The usually self-limiting and mild symptoms typically last 4 to 5 days. These include:

• cough
• fever
• nasal congestion
• shortness of breath

People at risk include:

• elderly people
• children
• people with comorbidities

"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.

“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

While no vaccine or treatment can prevent HMPV infection, to avoid the infection, individuals must:

Practice good hygiene and cover your mouth and nose with a tissue when coughing or sneezing, or use your elbow, not your hands, for it. And wash your hands properly, especially in healthcare settings.

Why Are People Hearing About The Virus Without Vaccine Now?

The reason people have not heard about it before is because its symptoms are nearly indistinguishable from other respiratory infections, so often it could go undiagnosed. Furthermore, earlier the COVID cases and influenza cases sparked up, which deviated the attention from HMPV. Now, with the season gone, and increased awareness around respiratory illnesses, greater attention to viruses like HMPV is also paid.

One in seven Indians, or over 14 percent of the population, suffers from some form of mental health disorder. Amid an increasing treatment gap -- up to 90 percent -- seen in several states, especially in North India, the government today reiterated the plan of launching a second National Institute of Mental Health and Neurosciences (NIMHANS) in the northern states.

NIMHANS-2 was first announced by Finance Minister Nirmala Sitharaman during the Union Budget 2026-27, to deliver specialized care for mental health and neurological disorders in north India.

Health experts and policymakers, as part of the government-led Post-Budget Webinar series, highlighted the growing burden of mental and neurological disorders in India and also stressed the urgent need to strengthen institutional capacity to meet emerging healthcare demands.

"One in seven Indians is affected by mental health disorders, while several states continue to face a treatment gap ranging from 70 to 90 percent," the experts said.

Noting that Non-Communicable Diseases (NCDs) account for over 60 percent of deaths in the country, they added that "neurological and mental health conditions are among the leading contributors to disability-adjusted life years (DALYs)," among the citizens.

Need For Tertiary Neuro-psychiatric Care

To address these, the experts called for ramping up tertiary mental health institutions and expanding specialized services.

The session, moderated by Vijay Nehra, Joint Secretary, Ministry of Health and Family Welfare, highlighted that North India currently lacks adequate tertiary neuro-psychiatric care facilities. These include areas such as:

• advanced neuroimaging,
• neurocritical care,
• specialized neurological services

Further, making a virtual address at the Post-Budget Webinar, Union Health Minister JP Nadda also highlighted the government’s focus on strengthening mental healthcare services in the country.

"NIMHANS-2 will be established in North India to expand advanced clinical care, training, and research," Nadda said.

"In addition, the Central Institute of Psychiatry, Ranchi, and the Lokopriya Gopinath Bordoloi Regional Institute of Mental Health, Tezpur, will be upgraded as regional apex institutions to strengthen mental healthcare services in the eastern and north-eastern regions," he added.

Meanwhile, the experts also stressed the need to improve services in underserved and geographically remote regions, including the northeastern states, through better infrastructure, capacity building, and targeted deployment of trained mental health professionals.

They also discussed strategies for expanding advanced neuro-psychiatric care and reinforcing India’s overall mental healthcare ecosystem. They proposed:

• Adopting a hub-and-spoke model supported by digital health platforms

This would allow tertiary institutions and centers of excellence to provide technical guidance, specialist consultations, and clinical support to district hospitals and community-level health facilities.

"Such a model would strengthen referral pathways and ensure that specialized mental health services are accessible to people even in remote and rural areas," the experts said.

• Integrating services under Tele-MANAS

Both existing and upcoming campuses of NIMHANS must be integrated , as this will enable a robust nationwide tele-mental health network that ensures

• timely counselling,
• psychological support,
• specialist consultations

• Digital follow-up systems

The experts called for the seamless integration of healthcare facilities, aligned with the vision of the Ayushman Bharat Digital Mission and the ABHA ID ecosystem. This, they said, will

• enable continuity of care,
• Improve monitoring of patients,
• Lead to better clinical outcomes

• A national Brain-Mind Cloud Network

The Network proposed under the National Health Mission would connect premier institutions such as All India Institute of Medical Sciences (AIIMS), state medical colleges, and primary healthcare centers through a digitally integrated platform.

It could also facilitate

• unified mental health records,
• AI-based screening tools,
• data-driven clinical decision support systems,
• tele-neuro-psychiatric hubs at regional centers.

California and New Jersey in the US are seeing an uptick in cases of human metapneumovirus (HMPV) -- a virus with no vaccine or treatment.

According to the US Centers for Disease Control and Prevention (CDC), HMPV can cause upper and lower respiratory disease. There is currently no vaccine to prevent it, and no specific antiviral therapy to treat it.

"Most people will recover on their own," the agency noted, but advised people who get sick to drink plenty of liquids, stay home, and rest.

As per the CDC's respiratory dashboard, the cases of HMPV steadily ticked up since November 2025. It accounted for over 5 percent of positive tests the week of February 14 through February 21.

While HMPV is not a "new" virus, having first been discovered in 2001, cases haven't spiked to this level in the US since an outbreak in April 2025, USA Today reported.

The New Jersey Respiratory Surveillance Report cited that about 4 percent of residents in the state are testing positive for HMPV. The HMPV cases, accompanied by RSV, COVID, and flu cases, are surging, increasing the number of people seeking emergency medical care.

As per the public database, WastewaterScan Dashboard, HMPV is rampant in Northern California -- specifically San Francisco, Marin, Vallejo, Napa, Novato, Santa Rosa, Sacramento, and Davis, the Independent UK reported.

What Is HMPV? Is It Dangerous?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).
