HMPV: The Respiratory Virus You’ve Probably Never Heard Of

When it comes to respiratory viruses, names like RSV, flu, and COVID-19 often dominate the headlines and conversations among public health folks. But there’s seasonal respiratory virus that deserves attention: Human Metapneumovirus (HMPV).

About Human Metapneumovirus | CDC

While it’s been circulating in the U.S. for decades, it hasn’t received the same spotlight as its viral cousins. Let’s break down what HMPV is, who’s most at risk, and how you can protect yourself and your loved ones.

What Is HMPV?

HMPV is a respiratory virus that’s part of the same family as RSV. It spreads through respiratory droplets, close contact, and touching contaminated surfaces.

Most people recover without issue, but for some, it can lead to severe complications like bronchitis or pneumonia. Unlike its sister virus RSV, there is no vaccine for HMPV.

Who’s Most at Risk?

Certain groups are more vulnerable to severe outcomes from HMPV:

  • Young children, especially those under 2 years old.
  • Older adults, particularly those over 65.
  • People with weakened immune systems or chronic conditions like asthma or COPD.
What Are the Symptoms?

HMPV symptoms can range from mild to severe and often resemble a cold or flu:

  • Cough
  • Fever
  • Lots of nasal congestion
  • Shortness of breath
  • Wheezing

For some, especially those in high-risk groups, these symptoms can escalate, leading to hospitalizations.

How Can You Prevent It?

The same precautions we take for other respiratory viruses apply to HMPV:

  • Wash your hands often with soap and water.
  • Avoid touching your face, especially your eyes, nose, and mouth.
  • Stay home if you’re feeling sick.
  • Clean and disinfect commonly touched surfaces.
Tracking Respiratory Viruses in Real Time

HMPV doesn’t have to be reported by the ADHS but that doesn’t mean we can’t monitor the spread of the virus.

Anybody can learn about the trends of how HMPV (and other respiratory viruses) are spreading in the US or regionally using the National Respiratory Virus Interactive Dashboard.

I ran the query just now and our Region of the US is currently in the middle of a big spike in HMPV infections. If you or someone you know has had a really bad cold that’s hung on for longer than normal – there’s a decent chance it was (is) HMPV rather than a run-of-the-mill cold.

The National Respiratory and Enteric Virus Surveillance System uses data from participating U.S. laboratories who voluntarily report weekly to CDC. They also report the specimen type, location, and week of collection. NREVSS has the most timely data to monitor viral seasons and circulation patterns.

The Bottom Line

While HMPV isn’t currently filling up emergency departments or rifling through assisted living centers as far as we know – it’s worth keeping on your public health radar—especially if you or your loved ones fall into a high-risk group.

Express Your Opinions about Bills this Session on AZLEG.gov: Here’s How

The Arizona State Legislature uses the ‘Request to Speak’ (RTS) system facilitate tracking of bills proposed and allowing the public to register an opinion on bills and to request to speak on a bill in a committee.

How to register your opinion at the Arizona State Capitol – via the AZ Mirror

It replaces the old slips of paper used back in the day and lets the committee chairperson know you want to speak to the committee. Under the old paper system, you could only sign in to speak or register an opinion if you were physically at the capitol.

After the initial setup at a kiosk located in the House or Senate, the RTS program allows you to participate from your home or office. When the committee is in session, the committee members and the public will see a list of names of people who have registered an opinion.

It also shows whether you want to speak or not, who you represent. You can also leave more detailed comments or links to resources in comment boxes. This information is also available if a person searches past committee agendas. Legislators, journalists and the public will see your bill position throughout the process.

A catch is that you’re required to come to the capitol the first time you use the RTS system. When you come to the Capitol, you create an account and sign in on one of the Kiosks in either the House or Senate.

If you create an account at home, you’ll only be able to use the Bill Status Inquiry application to track activity on a bill, not register an opinion or create a request to speak until you come to the capitol and sign in on one of the Kiosks here.

Here’s a quick tutorial summarizing how to get set up and use Arizona’s RTS system: Using the Request to Speak Program

Using RTS has a bit of a learning curve, but if I can become proficient at using it- anybody can!

Addressing Firearm Violence in Arizona: A Public Health Perspective

Guest blog from AZPHA Member RJ Shannon

RJ Shannon of Phoenix, Arizona is this ...

In the last few days including Thursday, November 28th there have been a rash of shootings all over the valley including smaller Arizona towns. We can no longer ignore the effects of this form of violence and the impact on our shared communities.

Since the Republican legislature and Governor Brewer passed and signed legislation that banned law enforcement agencies across the state from destroying firearms in 2013, according to the Johns Hopkins Bloomberg School of Public Health, there has been a 43% increase in firearm injuries and deaths in Arizona.

Every law enforcement agency must resell confiscated firearms back into our communities through a licensed broker, but after that, the trail may end, creating a proliferation of guns that are easily attainable.

The owner does not have to register these firearms nor face liability should an incident take place. Law enforcement agencies across Maricopa County and all other Arizona counties are seeing more risk to their officers along with the dire consequences of firearm threats and in many cases officer involved shootings.

Sadly, many of these shootings happen because of perceived threats when the threat is not visible but assumed. Too many times, the communities most affected by these misconceptions and biases are communities of color – Black, Brown, and Indigenous; folks experiencing mental health episodes and others unlucky enough to be in the wrong place at the wrong time – leaving injuries and deaths in their wake.

Lawsuits do not bring back the dead and may even help with the enormous treatment bills awaiting those who survive, but in the end, we all pay the price.

In a state like ours, it is impossible to know who is legally carrying concealed and who is not, and for the sake of the potential victim or survivor we should always know. To be clear, Arizona is NOT plagued by the irresponsible behaviors of responsible gun owners, but by those newer owners for whom there is no record of ownership or safety training.

Firearm regulation is necessary just as the authors of the US Constitution stated. ALL owners should register through a state-wide/Federal databank; ALL gun owners should purchase insurance and a license to carry concealed firearms.

ALL firearm owners should undergo safety training that offers secured storage recommendations with devices either donated or sold so that the incidents of unintentional/intentional and suicide injuries and deaths are more easily preventable. And ALL gun owners should face the same penalties for neglect leading to intentional or non-intentional injuries or deaths to others.

City councils, County Supervisors, school boards and State leadership along with concerned residents and stakeholders should determine zoning designations for locations where firearms are sold, so that they are not purchased from commercial or individual sellers anywhere close to schools, homes, and other sites where vulnerable persons may be present.

Arizona spent an outstanding sum of taxpayers’ dollars and employee hours determining the safest places to sell medical marijuana to protect the health and welfare of Arizona’s families. We must use the same reasoning regarding how, when and where firearms are sold and used. Arizona’s communities pay too high a price for our firearm associated injuries and deaths to ignore how firearms filter into our communities.

Finally, we invite businesses that rely on the sale and usage of firearms and gun owners to be partners in the prevention of unintentional injuries and increased suicides by guns that we experience among Arizona’s oldest and youngest community members.

It was not that long ago when Arizona law stipulated that any gun owner desiring to carry concealed had to take a safety class offered by the State with minimal payment by the owner. Sadly, the Arizona State Legislature overturned a terrific mandate. Together we must meet collaboratively to find the best way for your businesses to aid in saving lives while offering your expertise and sage advice to new firearm owners on how to use their firearms safely.

I am not naïve and recognize that these relationships between more experienced and less experienced owners have historically forged mentoring relationships, but not in a systemic and state funded way.

If the state wants to continue identifying as a 2nd amendment entity, there is nothing that precludes them from passing gun sense laws supporting the safety of all gun owners, their families, and communities – thereby indirectly adding protections that significantly protects all our lives.

Firearm injuries and deaths are not only a law enforcement issue, but more so, a major public health priority. Firearm injuries are the 2nd leading cause of death for Arizona’s children and teens. Firearm deaths are the number one cause of death for children and teens nationwide and there is no reason to believe that it will not soon be the case for Arizona’s children if things do not change.

According to the Johns Hopkins School of Public Health and the CDC, in 2022, Arizona had the 12th highest gun death rate in the US. In 2021, suspects used firearms in 128 domestic violence homicides. On Thanksgiving night this year (Thanksgiving Day, 2024) a man shot and killed his son in Phoenix during a domestic dispute. Arizona, haven’t you had enough, yet?

These injuries and deaths are almost 100% preventable when owners secure their firearms, ownership is identified & registered, the purchaser is mandated to take safety training, insurance is imposed (you know, like we do with cars???) along with strict age restrictions and provisions for requiring individual and family safety assessments.

When children and others find unsecured weapons and either harm themselves or others as a result, the owners must be held accountable. The responsibility lies with the owner and not the person who finds an unsecured firearm in the home or vehicle.

The Arizona Child Fatality Review Program recently cited that the leading risk factors of Firearm Injury deaths for children and teens are the following: Access to firearms = 100%; Firearm not stored properly = 66%; CPS History with Family = 63%, Substance use = 53%. Criminal Act = 27%, which when identified and assessed for gun ownership and safety measures, were considered almost 100% firearm injury preventable.

According to Channel 12 news, Maricopa County school campuses found more than 100 guns and received numerous threats since 2019. It turns out that it is not a statistic that Arizona tracks and for which the State of Arizona’s Department of Education takes no responsibility believing that it is the community’s responsibilities to pursue these issues.

Parents, if they won’t do something, then we must! If Arizona adopted all or some of the recommendations, responsible gun ownership would increase to support those firearm- owning Arizonans who are already responsible to themselves, their families, and their communities.

These recommendations are only the first steps, but Arizona needs to begin again somewhere. It is past the time to look at who we are but now deciding who we want to be. For some reason, we have determined that it is all right to declare war on ourselves. How about we lead the way towards community peace and reconciliation through a public health and safety lens that supports all of us, our families, and our communities? Just sayin’…

Learn How the Arizona State Legislature Works with this Engaging Podcast

The Arizona State Legislature will meet on Monday, January 8, 2024. Many legislators will hit the ground running with bills that they already have in the hopper. See the bills that have been pre-filed so far

That means we need to be ready to fight for good bills, fight against bad bills, and be prepared to advocate for adjustments for bills somewhere in the middle right out of the box.

You can prepare your advocacy chops before the legislative session starts by listening to the Arizona Common Ground podcast, an eight-episode educational podcast series that gives a behind the scenes glimpse of the state legislative system and learn how bills can become laws. The Consumable Podcast Series is Available as:

Krista Romero-Cardenas, MPH, a former senior instructional specialist for the Western Region Public Health Training Center and alumna of the Mel and Enid Zuckerman College of Public Health is the creator and host of the Arizona Common Ground podcast – an eight-episode educational podcast series that will take you through the process of how bills are passed in Arizona.

Arizona Legislative Session Begins Monday, January 13: Here’s Our Advocacy Approach

January 13 marks the beginning of the 2025 legislative session. The kickoff will be the Governor’s address to the legislature where she’ll outline what she sees as priorities.

AzPHA will follow the session closely and express our support or opposition to bills based on a simple core principle…  we support bills that will have a positive impact on public health especially when they are evidence-based or evidence-informed.  We will oppose bills that are likely to have a negative impact on public health. 

Our support or opposition to bills is located on the https://www.azleg.gov/ site under RTS Current Bill Positions. We have a host of Resolutions that also guide our advocacy which are posted on our website.

The fact that we have Resolutions on so many core public health priorities make it easy for us to be swift with our support or opposition. Our Resolutions go all the way back to the 1930s. They are initiated by either the Board or our members and all resolutions have been voted on and approved by our members.

Our Public Health Policy Committee has a discussion board on Basecamp and that’s also where we post information, research and documents related to public health policy.  Let me know if you’d like to sign up for that Basecamp site at [email protected].

Our policy committee also has conference calls Fridays at 2pm starting January 17. Details are in our policy committee basecamp (email me at [email protected] to get access to the members policy committee Basecamp).

Transforming Public Health Practice With Generative Artificial Intelligence

Transforming Public Health Practice With Generative Artificial Intelligence | Health Affairs

Abstract: Public health practice appears poised to undergo a transformative shift as a result of the latest advancements in artificial intelligence (AI). These changes will usher in a new era of public health, charged with responding to deficiencies found during the COVID-19 pandemic and managing investments required to meet the health needs of the twenty-first century.

In this Commentary, we explore how AI is being used in public health, and we describe the advanced capabilities of generative AI models capable of producing synthetic content such as images, videos, audio, text, and other digital content.

Viewing the use of AI from the perspective of health departments in the United States, we examine how this new technology can support core public health functions with a focus on near-term opportunities to improve communication, optimize organizational performance, and generate novel insights to drive decision making.

Finally, we review the challenges and risks associated with these technologies, offering suggestions for health officials to harness the new tools to carry out public health goals.

Three Applications for Generative AI Models in Public Health

Public Communication

Organizational Performance

Novel Insights

Public health has the potential to rapidly evolve with the advent of new technologies. But ultimately, AI, including generative AI, is just a tool, similar to a vaccine or genomic surveillance.

Public health practitioners will need to master the new tools and learn to use them as part of a larger public health strategy. This discussion reviews the use of AI and presented three early use cases for generative AI related to communications, organizational performance, and generating novel insights that align with three of the eight core capabilities defined in the Foundational Public Health Services framework.

H5N1 Influenza in Valley Wastewater: Does it Matter?

Yesterday brought an unexpected detection of H5N1 ‘avian’ influenza RNA in wastewater from three cities in Maricopa County—Phoenix, Tempe, and Surprise. H5N1 mostly affects wild birds, domestic poultry, and a handful of mammal species (including mild infections among human agricultural workers. But, with no human-to-human transmission and urban Maricopa County not being super agricultural, its presence in wastewater raises intriguing questions about the source. Let’s explore why and the implications.

What is H5N1?

H5N1 (aka avian influenza) is a strain of avian influenza virus that has caused severe outbreaks among wild birds and domestic fowl. Infections in mammals have been rare and mostly mild. Some agricultural workers with close contact with infected birds or cattle have been infected, but with mild symptoms and with no documented human-to-human transmission.

The Wastewater Detections

The ADHS State Laboratory confirmed the presence of H5 RNA in wastewater samples collected from Phoenix, Tempe, and Surprise. The finding was surprising because these cities are not known for large-scale poultry farming (where such a virus might be expected in domestic wastewater).

Also, all three cities say that their stormwater systems (which collect rainwater and runoff) are completely separate from their wastewater systems (which handle sewage). This separation means that the virus’s presence can’t be attributed to wild birds contaminating street drains and then getting into domestic wastewater.

Where’s it Coming From?

So, where is the H5 RNA coming from? After consulting with public health experts, the most plausible explanation points to backyard chicken flocks. Backyard poultry keeping has grown in popularity, and infected chickens could easily introduce the virus into wastewater through improper disposal of chicken tissue via household sinks.

Note: ARS 11-820.04 prohibits counties from adopting laws or regulations prohibiting residents from keeping up to six fowl in their backyards.

While it’s theoretically possible the source of the detections of H5 in wastewater are human infections, it seems like a longshot since no human-to-human transmission of H5N1 has been documented.

What’s Next?

As part of normal annual influenza surveillance, randomly selected specimens from human influenza infections (which is increasing quickly right now) are routinely sequenced – and if some of them are H5 (rather than the ubiquitous H1N1 and H3N2 strains) we should know shortly.

Note: The ADHS State Lab (which confirmed these detections) is finishing its validation protocol for the H5N1 wastewater validation test, with certification by the CDC expected soon. ADHS’ H5N1 assay for human infections IS validated.

Should We Be Concerned?

For now, there’s no need for alarm. Human cases of H5N1 remain rare, mild and there’s is no evidence of human-to-human transmission. However, these detections underscore the importance of vigilance, proper biosecurity measures for backyard flocks, and ongoing surveillance of both human and animal health.

We’ll continue to be on top of local and national developments – but for now there’s nothing to freak about.

Association v. Causation: A Key Distinction when Developing Public Health Policy

One of the key aims of public health is to assess the cause of disease or bad outcomes so we can design interventions.  In order to do that, we need to be able to tell the difference between when something is actually “causing” an outcome and when the exposure or condition is simply “associated” or “correlated” with an outcome. 

Whether something causes or is simply associated with a bad outcome is a key factor when we design interventions.  The following examples may shed some light on the relationship between risk factors, outcomes, and the difference between association and causation.

A study in the American Journal of Pathology “…persons with tattoos appear to die earlier than those without”.   The study found that people in the study group with a tattoo died 14 years earlier than people without a tattoo (p = .0001).

This study doesn’t conclude that having a tattoo actually causes people to die earlier.  Rather, it suggests that having a tattoo may be associated or correlated with other independent factors that might lead to an earlier death (e.g. people with tattoos may be more likely to have risk-taking behaviors).

In order to conclude that an exposure or condition actually causes an outcome, researchers randomly divide study participants into groups by assigning them to the exposure or condition they’re studying (experimental group) while making sure that another group doesn’t have the exposure or condition (control group). 

If the expected outcome is observed within an experimental group and not in the control group, it’s likely that exposure actually caused the outcome.

For example, if researchers were to expose one randomly-selected group of people to poison ivy via direct contact with poison ivy leaves – while not exposing the control group to poison ivy – they would most likely be able to establish that poison ivy actually caused the rash.  It’s this random assignment to conditions that make experiments sophisticated enough to detect actual causation.

Judging the causal significance of an association or causation is both a science and an art.  The gold standard for determining what is an association and what is actual causation is described in a 1964 Surgeon General’s Report on this topic.

Some of the research you read about shows a correlation or association between variables, not causation.  When you’re reading scientific studies, make sure you look for whether the study is talking about an “association or correlation” or whether they are talking about causation.

Editorial Note: Mr. Robert F Kennedy Jr appears to need an in-depth tutelage on the difference between anecdotes and stories and the difference between association & causation. Time and again Mr. Kennedy bases his opinions on spurious reports, anecdotal stories and some articles that draw conclusions about the association between various stimuli and outcomes rather than focusing on causation.

That mind-set is relatively benign when it’s held by a private sector lawyer with a famous name – but it’s potentially dangerous when the person is in charge of nearly 30% of the U.S. federal budget, health care for the majority of the country and comprehensive regulatory authority of drugs, food and medical devices, and the US publicly funded research mission.
