With 6,000 cases of Legionnaires reported annually in the United States, scientists still think it is underdiagnosed as it could be hard to distinguish from other kinds of pneumonia or respiratory issues.

As of now, New York City has fallen prey to Legionnaires' disease outbreak. At least 22 people have fallen ill, and one person has been declared dead in Harlem, as per the New York City Health Department.

The Reason Of This Spread

As per the city health officials, people became ill after breathing in bacteria sprayed from cooling tower in central Harlem. Cooling towers help regulate building temperature. The city health department also said in a news release on Wednesday that it was testing cooling towers in the area and are continuously investigating the outbreak.

What Is The Legionnaire's Disease?

As per the Centers for Disease Control and Prevention (CDC), Legionnaire's disease is a serious type of pneumonia that is caused by Legionella bacteria. This bacteria is known for causing two types of diseases, one of them being Legionnaire's disease, a severe form of pneumonia; while the other one is Pontiac fever, which is a mild illness that can include fever, muscle aches and headaches.

It is very rare that this bacteria can cause infection outside of the lungs and affect heart or wound infections, notes CDC.

Legionnaires Common Symptoms

Legionnaires' disease symptoms usually develop 2 to 14 days after exposure to Legionella bacteria, but it can take longer.

The symptoms of Legionnaires' disease are similar to other types of pneumonia.

Symptoms include:

• Cough
• Fever
• Headaches
• Muscle aches
• Shortness of breath

Other symptoms, such as confusion, diarrhea, or nausea can also occur.

After this outbreak, which has been linked with a cluster, the deputy commissioner of division of infectious diseases at the New York City Department of Health and Mental Hygiene, Dr Celia Quinn, said that the risk is low for most people, however, there could be additional cases linked with this cluster.

Legionnaire's Disease in the US

Cases have been steadily rising over the past two decades. While there isn’t a single known cause for this increase, experts believe several factors may be contributing, including aging water infrastructure, poor system maintenance, rising water temperatures, and improved disease tracking and awareness.

Outbreaks are more common during the warmer months, particularly summer, when more buildings rely on cooling towers for air conditioning systems.

Health professionals note that while a similar report in winter might raise fewer concerns, the combination of summer heat and rising case numbers highlights the importance of staying vigilant during peak Legionella season.

Who Are At Risk?

While most healthy people exposed to the bacteria do not get sick, people who are 50 or older, or are current or former smokers, or people with a weakened immune system or chronic conditions, such as cancer, lung disease, diabetes or kidney and liver failure may be at a higher risk.

Legionnaires’ disease often becomes more severe within the first week of symptoms. In serious cases, patients may need hospitalization and oxygen support. If the illness progresses, it can lead to complications like lung failure or heart damage. According to the CDC, about 1 in 10 people who contract Legionnaires’ disease do not survive.

Is Legionnaires’ Disease Contagious?

Legionnaires’ disease doesn’t spread from person to person. It’s usually contracted by breathing in mist or vapor contaminated with the bacteria. Outbreaks are often linked to cooling towers in large cities. In rare instances, the illness can also be caused by inhaling contaminated soil.

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.
