While the world is still trying to catch its breath from the aftermath of COVID-19, a new virus is quietly gaining prominence in the headlines—H5N1 avian flu, or bird flu. The recent upsurge of this highly pathogenic virus among the dairy cattle of the United States, and the increasing number of human cases, has raised alarm among global health experts. Is H5N1 taking silent steps toward becoming the next pandemic? The key is to carefully look at the numbers, the science, and the public health response.
In a frightening trend, Idaho has become the hotbed of the ongoing H5N1 outbreak in U.S. livestock, with the US Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) verifying 86 cases in dairy cows—the second-largest in the nation following California. The outbreak, which took a massive turn in March 2024, has now reached 17 states, with more than 1,047 cases detected in dairy herds.
This is a troubling change in the behavior of the virus, previously recognized to infect wild birds and poultry. The spread of the virus into mammalian livestock and now into humans suggests a chilling evolutionary trend that health authorities are scrambling to contain.
As reported by the Global Virus Network (GVN), more than 70 human infections have been confirmed in the U.S. since the outbreak began, with one reported fatality. Although human-to-human transmission has not yet been reported, scientists caution that virus mutations—particularly in mammalian hosts—may enhance the potential for person-to-person spread, potentially leading to a pandemic.
Dr. Sten H. Vermund, GVN Chief Medical Officer, explains, "In its capacity to infect animals and humans, as well as in recent genetic evolution, the threat of H5N1 disease highlights the need for active surveillance and immediate response."
Avian influenza A(H5N1) is an extremely contagious virus that, while initially infecting birds, can also cross-species, including to mammals and humans. When contracted by humans—most commonly through close contact with infected animals or contaminated surroundings—the disease tends to be severe and potentially deadly.
The World Health Organization (WHO) has cautioned that if this virus develops to transmit effectively among humans, it has the potential to create a world health emergency equal to previous pandemics. Already, 168 million birds have been slaughtered in the U.S. since 2022 because of avian flu outbreaks, and the threat to food supply chains, animal well-being, and human health is staggering.
The GVN, in partnership with the Centers for Disease Control and Prevention (CDC), has called on governments around the world to implement a multi-pronged preparedness strategy to prevent the virus from spreading before it mutates into a pandemic-strain. The strategy entails:
Even as the outbreak was large, the CDC insists that the risk to the general public is still low. The agency has, however, suggested added caution for those who are in close contact with animals, particularly dairy and poultry workers. Hygiene, wearing of PPE, and prevention of exposure to ill animals continue to be paramount.
The CDC also insists on vigilance and says:
"We are following people with exposures to animals very closely, and continue to closely monitor the situation."
The short answer is: not yet—but we shouldn't wait for it to do so. The virus has yet to reach sustained human-to-human transmission, the key element which converts an outbreak into a pandemic. But the spread of the virus in cows, coupled with the number of human infections and a confirmed death, are troubling indications that urgently need global notice.
Learning from COVID-19, experts call on policymakers to act now and not respond later. Research on vaccination, quick diagnostics, public health preparedness, and international collaboration need to be prioritized in order to remain ahead of the next move of the virus.
The H5N1 epidemic sweeping the United States is an awakening call. Short of a pandemic, it is a definite indication that the edge between animal and human viruses is rapidly growing thin. Whether or not H5N1 becomes an actual worldwide menace hinges on how quickly and efficiently we act now.

In a controversial move that has rattled the U.S. medical community, federal health officials have severed ties with more than half a dozen major medical organizations from participating in government vaccine advisory workgroups.
The decision, communicated via email on Thursday, disinvites top experts from these groups from contributing to the workgroups that support the Advisory Committee on Immunization Practices (ACIP), a key body that guides the nation’s vaccination policies.
Organizations affected include the American Medical Association (AMA), the American Academy of Pediatrics (AAP), the Infectious Diseases Society of America (IDSA), and several others, many of whom have historically played a critical role in shaping vaccine guidelines.
“This is deeply concerning and distressing,” said Dr. William Schaffner, a renowned vaccine expert from Vanderbilt University who has been involved with ACIP workgroups for decades. “Removing these organizations will likely create conflicting messages about vaccine guidance. Patients might hear one thing from the government and another from their personal doctors.”
For years, the ACIP has relied on a structured system where experts from various medical and scientific fields evaluate vaccine data and help draft recommendations. These recommendations, once approved by the Centers for Disease Control and Prevention (CDC), often inform clinical practice and determine insurance coverage.
But according to an email obtained by Bloomberg and confirmed by federal officials on Friday, the medical organizations are now being sidelined on the grounds that they are “special interest groups” and are assumed to carry a “bias” due to the populations they serve.
Dr. Schaffner defended the former system, highlighting how professional organizations offered practical insights on how recommendations could be realistically implemented in clinical settings. Importantly, all members were subject to conflict-of-interest vetting, ensuring objective guidance, he added.
This latest shake-up follows an earlier, unprecedented move in June when U.S. Health Secretary Robert F. Kennedy Jr. abruptly dismissed the entire ACIP panel, accusing it of being too closely aligned with vaccine manufacturers. Kennedy, a former leader in the anti-vaccine movement, has since appointed several known vaccine skeptics to the new committee.
Among the organizations removed from the workgroup process are the American Academy of Family Physicians, American College of Physicians, American Geriatrics Society, American Osteopathic Association, National Medical Association, and the National Foundation for Infectious Diseases.
In a joint statement released Friday, the AMA and several of the disinvited organizations denounced the decision, calling it “irresponsible” and “dangerous to our nation’s health.” The statement warned that excluding their medical expertise “will further undermine public and clinician trust in vaccines.”
The groups urged the administration to reverse the decision, emphasizing the importance of transparency and collaboration in public health decision-making.
Several of the ousted organizations had previously criticized Kennedy’s overhaul of the ACIP. Last month, three of them joined a lawsuit challenging the government’s decision to halt COVID-19 vaccine recommendations for most children and pregnant women, a policy shift that has been widely criticized by public health experts.
Meanwhile, newly appointed ACIP member Retsef Levi, a professor of business management with no formal medical background, defended the administration's direction on social media. Levi wrote that future workgroups would “engage experts from an even broader set of disciplines,” and claimed that membership would be based on “merit & expertise, not organizational affiliations with conflicts of interest.”
The Department of Health and Human Services (HHS) has not yet disclosed which experts will replace the disinvited members or when the new workgroups will begin operating.

The United States Centers for Disease Control and Prevention (CDC) is assessing a potential travel notice for China following a sharp rise in cases of chikungunya, a mosquito-borne viral infection that has sparked public health alarms in southern China, as reported by the Independent and the South China Morning Post.
Nearly 5,200 infections have been reported in the Guangdong province since early July, with most of them concentrated in the city of Foshan. Health officials there have since escalated their emergency response to a level III alert, which signals a “relatively major” public health threat in China’s four-tier system.
While the CDC has not yet published a formal advisory, a spokesperson told The Independent that the agency is “aware of the reported chikungunya outbreak in Guangdong Province in China and is currently assessing the size and extent of the outbreak.”
Chikungunya is a viral infection transmitted by the bite of an infected Aedes mosquito, the same mosquito species responsible for dengue and Zika. Symptoms typically include sudden onset of fever and joint pain, but may also include headache, muscle pain, swelling, and rash.
Although most cases are mild and self-limiting, some infections can lead to prolonged joint pain or, in rare cases, long-term complications. Serious outcomes are more likely among those with pre-existing health conditions. There are no antiviral treatments available, so prevention, particularly mosquito control and bite avoidance, remains the primary approach.
Vaccines against chikungunya have recently become available and are recommended for travelers to high-risk areas, although they are not yet widely accessible.
According to local health authorities in Foshan, around 95% of reported cases have been mild, with patients recovering within a week. However, the outbreak’s rapid spread has raised concern among international health bodies.
The outbreak in China follows a global pattern of chikungunya resurgence. The World Health Organization (WHO) issued an alert last week warning of the risk of the virus repeating its global spread from two decades ago. Diana Rojas Alvarez, a medical officer with WHO, said that nearly 5.6 billion people across 119 countries live in areas where the virus could potentially spread.
Chikungunya was first identified in 1952 in Tanzania and has since been detected in more than 110 countries, including major outbreaks in India, Italy, and the Americas. The virus is not spread from person to person; instead, it is carried by mosquitoes that have fed on infected individuals and then pass it to others.
The concern is not just local: international travel plays a key role in how the virus crosses borders. Infected travelers returning to or visiting countries with mosquito populations capable of transmitting the virus can trigger new outbreaks.
The first case in this outbreak was reported in Foshan’s Shunde district on July 8 and was believed to be imported. Since then, local and national health authorities have moved quickly to contain the spread.
Measures taken include the use of drones to detect rooftop water accumulation, the release of larva-eating fish into lakes, and widespread public awareness campaigns. Residents have been urged to eliminate standing water, install window screens, and wear protective clothing.
Hospitals in affected areas have increased bed capacity for confirmed cases and designated specialized treatment centres. Border controls have been stepped up in Hong Kong to prevent imported cases from mainland China, with expanded testing capabilities introduced at key entry points.
The CDC’s travel health notices are used to inform travelers about global disease risks and provide precautionary guidelines. The warning system has four levels, ranging from “practice usual precautions” (Level 1) to “avoid all travel” (Level 4).
As of now, China has only a Level 1 travel health notice for measles. However, the CDC has issued Level 2 notices for chikungunya in several countries including Bolivia, Kenya, and Madagascar in recent months.
If the CDC decides to escalate China’s status, it would be a significant development, both in terms of travel planning and diplomatic perception.
The potential issuance of a travel notice also comes against the backdrop of complex US–China relations. While the CDC’s move would be grounded in public health data, the optics of a travel warning could have broader implications.
On Thursday, Chinese foreign ministry spokesperson Guo Jiakun responded to the reports, saying that China is in communication with the WHO and “making every effort to ensure a safe environment for travelers.”
The WHO has not issued any travel restrictions related to the outbreak but continues to monitor the situation closely.
With mosquito-borne diseases on the rise globally, driven by climate change, urbanization, and increased mobility, health experts advise travelers to stay informed and take preventive measures.
“Mosquito control is key,” said an official from the Hong Kong Centre for Health Protection. “Simple actions like using insect repellent, sleeping under mosquito nets, and avoiding stagnant water can go a long way in preventing infection.”
As global health agencies monitor the chikungunya outbreak in China, travelers to affected areas should remain vigilant and stay updated with official advisories. Prevention remains the best protection in the face of a disease with no cure.

August is known as the Hair Loss Awareness Month and the first Saturday of this month is known as the International Alopecia Day.
Hair loss is a common concern, affecting over 85% of men, 55% of women, and between 15–38% of adolescents at some point in their lives. For those with advanced or long-lasting alopecia, the emotional and social impact can be profound.
Baldness has been linked to significant declines in mental health and quality of life, with higher rates of anxiety, depression, stress, and reduced self-esteem.
It is a term used for hair loss that affects the scalp or even the entire body, temporarily or permanently. Alopecia can happen due to variety of reasons, including heredity, hormonal changes, and medical conditions, or as simple as normal aging.
The day aims to form a community of those who experience this autoimmune disease.
International Alopecia Day was initiated by American activist Lynn W. Walker in 2011. She herself lives with a diagnosis of alopecia totalis and created this day to unite people with similar experiences, reduce stigma, and highlight beauty and strength regardless of the presence of hair.
This year's theme as per Alopecia UK is, 'Strength in Numbers', which urges more and more people to join the International Alopecia community and to do away with the shame of hair loss and form a support group, across the world.
As per the National Library of Medicines, US, alopecia refers to the loss or absence of hair in areas where it normally grows. It can be localized or widespread, temporary or permanent, and affects people of all ages and genders. As a symptom with diverse underlying causes, alopecia is generally categorized into two main types: nonscarring (the most common) and scarring (cicatricial).
For many patients, hair loss leads to significant emotional distress and a reduced quality of life. Accurate diagnosis requires a thorough history, physical examination, and targeted investigations to identify the root cause and guide effective treatment. Managing alopecia can be challenging, but this overview outlines key assessment and treatment approaches for the most common forms to support better outcomes.
There are several main types of alopecia, including:
alopecia areata: an autoimmune disease that causes hair loss, often in small, round patches on the scalp, but it can occur anywhere on the body
alopecia totalis: complete loss of scalp hair
alopecia universalis: hair loss over the entire body
androgenetic alopecia: hereditary baldness
