The U.S. Department of Health and Human Services (HHS) released new definitions for 'sex,' 'man,' and 'woman', an action that has provoked widespread discussion in health, scientific and policy communities. While proponents believe the revisions bring back biological truth, opponents caution that they will weaken science and harm healthcare policies.

On February 19, HHS Secretary Robert F. Kennedy Jr. released new federal guidelines that strictly define sex as an unchanging biological category based on reproductive function. The memo claims that sex is genetically determined at birth and does not change throughout life, making it clear that biological sex cannot be altered by medical treatment or self-identification.

The guidelines establish a female "as an individual who has a reproductive system that produces eggs (ova) and a male as an individual whose reproductive system produces sperm". The memo also indicates that hormone therapy or surgery does not change an individual's biological sex, emphasizing the view that sex is strictly determined by reproductive function. Also, it explains that sexual development disorders are not a third sex because they do not lead to the formation of a new gamete type.

These definitions will now be used in all federal agencies, affirming a binary definition of sex in federal policy and regulations. This action has been met with both approval and disapproval with those in favor believing it brings biological truth back to federal guidelines and those opposed believing it overlooks scientific complexity and may harm healthcare policies for transgender and intersex people.

Supporters of the policy, such as former HHS Office for Civil Rights Director Roger Severino, have praised the move as a return to "science and common sense." The initiative is also linked to an executive order by former President Donald Trump, which required the federal government to recognize only two sexes.

"Today, this administration is restoring common sense and biological reality to the federal government," Kennedy stated.

Its supporters contend that the former strategy, where it acknowledged gender identity in addition to biological sex, introduced uncertainty in the domains of legal protections, health coverage and data collection. They assert that affirming biological definitions will assist in upholding certainty in medical and scientific studies.

"It took a lot of years of work but we are now back to science and common sense," responded Roger Severino, the previous director of the HHS Office for Civil Rights (OCR) during the first Trump administration.

Critics Warn of Negative Health and Scientific Impacts

The move has been severely criticized by medical professionals and lobby groups, with the latter citing that the action disregards widely accepted scientific research on gender diversity. The groups argue that the policy fails to support huge bodies of research into gender identity, intersex, and how hormones affect biological sex. Through enforcing strict definitions, critics fear that the guidelines might limit transgender and nonbinary access to critical healthcare services especially those aiming at treating gender dysphoria.

Furthermore, public health research can be held back, since data collection depends on a deeper comprehension of sex and gender in order to appropriately represent diverse groups. The inability to adapt the definitions may compromise scientific progress in medical research and healthcare policies. Moreover, opponents claim that the memo overlooks the important contribution of social and psychological determinants in the development of gender identity, which have been universally acknowledged by medical societies and researchers across the globe.

How The New HHS Guidelines Might Affect Health and Healthcare

The new definitions might have significant implications across several divisions of HHS, impacting key areas like healthcare coverage, public health research, and emergency response planning.

Health Care Coverage and Affordability

Insurance companies and health centers can now be obligated to adhere to strict biological definitions of sex, with the possibility of influencing transgender healthcare service coverage, including gender-affirming treatments. This would create legal confrontations regarding medical discrimination.

Public Health and Disease Control

The epidemic studies tend to examine health hazard by gender identity as well as biological sex. If studies were limited to dual categorizations, they could frustrate attempts at comprehending as well as coping with health gaps among transgender people and nonbinaries.

Emergency Preparedness and Response

Public health interventions, such as emergency response and emergency care, typically take gender identity into account in attending to displaced or vulnerable persons' needs. Such a rigorous biological approach may truncate the utility of these efforts.

Food and Drug Safety

The FDA and regulatory agencies could have issues with approving medications that act differently according to gender identity or hormone treatment. This could affect the treatment plans for transgender individuals with diseases like osteoporosis or cardiovascular disease.

Scientific Research and Innovation

Medical and psychological studies can be impacted by limitations placed on defining gender. Funding for studies of gender identity, hormone interaction, and social determinants of health may be barred.

Helping Families and Communities

Initiatives that support non-traditional family forms, including those with transgender children or parents will be hindered if federal laws fail to acknowledge gender identity as more than an either-or differentiation.

The HHS's newly promulgated definitions of sex, man, and woman are a sweeping policy change with profound implications for healthcare, research and public health. Whereas supporters claim these definitions bring biological clarity, detractors caution they ignore scientific facts and potentially do harm to vulnerable communities. Controversy around the changes will likely persist as policymakers, medical providers and advocacy groups consider the long-term effect on health and society.

Coughs. Sneezing. Wheezing. All of this can be heard everywhere, with many people taking sick leaves, and coming back to office still with health complains. This is what is happening in Delhi as the national capital remains in the 'very poor' category for its Monday morning Air Quality Index (AQI). The average AQI of the city stood at 318 on 7am, as per the Central Pollution Control Board (CPCB). The thick layer of smog has engulfed the city and there has been no improvement to get rid of the toxic air. Visibility too has been reduced in several areas, including Anand Vihar, India Gate, Dwarka, and ITO.

Amid the continuously worsening air condition in Delhi, the government has now formed an 'expert group' to combat air pollution as health crisis rise.

The panel will study how pollution builds up from human activity as well as natural causes and will recommend technology upgrades, policy reforms, and sector specific interventions that can be put into action.

Who Will Lead the Expert Panel

The group will be chaired by retired IAS officer and former Union Environment Secretary Leena Nandan. Other members include former CPCB member secretary Dr JS Kamyotra, IIT Delhi professor emeritus Mukesh Khare, IIT Kanpur professor emeritus Mukesh Sharma, and Dr Suneel Pandey, director of Circular Economy and Waste Management at TERI. Representatives from CAQM, the IMD, APAG, PHDCCI and senior officials from the Delhi government are also part of the group. The Secretary of Environment and Forest is a member, and the DPCC chairman will serve as member secretary.

What the Group Will Do

This expert panel will act as a high level advisory body, offering clear, actionable guidance that can shape both emergency responses and long term reforms. It will track the progress of current pollution control programs, study global best practices, and flag where corrections are needed. The group will meet every month, either in person or virtually, and will receive administrative support from the Delhi Pollution Control Committee. The initial tenure is six months, with the option to extend if required.

Government Planning and Oversight

Chief Minister Rekha Gupta has approved the expert group, along with a separate High Level Implementation Committee chaired by the Chief Secretary. While the expert group will guide policy and strategy, the implementation committee is responsible for enforcing directives, coordinating across departments, and ensuring timely action. Delhi BJP leader Manjinder Singh Sirsa has welcomed the move and said that combined efforts from the government and citizens can make a meaningful difference.

Delhi’s Pollution Levels Are Rising Fast

A new analysis by the Centre for Research on Energy and Clean Air (CREA) highlights the scale of the crisis. Delhi’s air pollution almost doubled in November, with average PM2.5 levels touching 215 micrograms per cubic meter. The city recorded 23 days of very poor air, six severe days, and only one poor day. Although stubble burning played a smaller role this year, contributing an average of 7 percent, the pollution remained dangerously high.

Across India, pollution trends were equally worrying. Nine of the ten most polluted cities saw higher pollution levels than last year. Ghaziabad was the worst affected, with PM2.5 levels at 224 micrograms per cubic meter.

According to CREA analyst Manoj Kumar, declining stubble burning shows some progress, but major year round sources such as transport, industry, power plants, and other combustion activities continue to drive the crisis. Without strong emission cuts in these sectors, pollution levels will keep breaching national standards.

Doctors Warn of a Deepening Health Emergency

In an interview with ANI, doctors from AIIMS described Delhi’s air quality as a medical emergency. Prof Dr Anant Mohan and Dr Saurabh Mittal from the Department of Pulmonary, Critical Care, and Sleep Medicine said the current situation is now putting vulnerable groups at serious risk, including pregnant women, unborn babies, newborns, and adults with heart or neurological conditions.

Dr Mohan warned that the impacts may be felt for generations. Since the particles are extremely small, they can pass from a pregnant woman to the fetus and interfere with growth. Babies exposed to such conditions in the womb are more likely to be underweight and may have weaker lungs as they grow. Some complications might show up only later in life.

Dr Mittal added that the effects of toxic air go far beyond respiratory illness. Prolonged exposure is increasing cases of breathlessness, lung inflammation, asthma attacks, and chronic conditions like COPD. Fine particulate matter is also entering the bloodstream, raising the risk of heart attacks and strokes.

The growing health concerns underline the need for immediate and coordinated action, making the work of the newly formed expert group even more urgent.

How To Read Delhi's AQI?

0-50: 'good'

51-100: 'satisfactory'

101-200: 'moderate'

201-300: 'poor'

301-400: 'very poor'

401-500: 'severe'

It is that time of the year when cough and colds are at its peak and everyone you know if affected by it. However, the health experts have warned that this winter could be worst, worse than the previous one. Why? Because this winter may have the most severe flu outbreaks in decades. The worst part? It is already wreaking havoc on the NHS.

The flu strain being talked about here is the H3N2 strain, what has also been named as the "unpleasant" by health experts. The experts have warned that NHS could face a "tidal wave" of illness ahead of Christmas. A per the reports, hospital admission rates for flu has already gone up to 56 per cent, as compared to the same week last year. As per the health experts, wearing a mask outside is must, especially if they feel unwell, and have encourages those who are eligible to get their vaccination.

What Is the H3N2 Strain?

H3N2 is one of the two main influenza strains currently in circulation. Also referred to as subclade K, it is the most prevalent flu strain in England right now, according to the UK Health Security Agency (UKHSA).

What Are The Doctors Saying?

The Independent spoke to Dr Giuseppe Aragona, GP and a medical adviser for Prescription Doctor, about this new strain and the ways to prevent sickness.

Dr Aragona explained that the letters and numbers used to classify flu strains come from the virus’s surface proteins called haemagglutinin, represented by H, and neuraminidase, represented by N.

He said that this specific combination can sometimes lead to more serious illness, particularly in older adults and people with underlying health conditions.

He added that H3N2 changes frequently, which means the version circulating this year may differ from earlier years or from the strain included in the seasonal vaccine. This can leave people more vulnerable to infection.

What are the symptoms?

According to the UKHSA, flu symptoms tend to appear suddenly. Extreme tiredness is common and this often helps distinguish flu from a cold, which develops more gradually.

The symptoms linked to H3N2 have been similar to typical seasonal flu. These may include fever, cough, a runny nose, body aches, vomiting or diarrhea.

People at higher risk of complications include children under five, especially those under two, adults over 65, pregnant women and individuals with chronic medical conditions such as asthma, diabetes, heart disease, weakened immunity or neurological illnesses.

If someone develops flu symptoms after close contact with pigs, doctors advise informing a healthcare provider immediately and mentioning that exposure.

How high are flu rates right now?

NHS England reported that an average of 1,717 patients a day were admitted to hospital with flu last week. This is a 56 per cent rise from the same period last year.

• The rates are seven times higher than in 2023, when hospitals saw an average of 243 flu patients a day.
• This spike follows Australia’s biggest flu season on record, which often predicts how the UK will fare.

Why is H3N2 hitting harder this winter?

Dr Aragona said several factors are contributing to a more challenging flu season. The season has begun earlier than usual, giving the virus more opportunity to spread.

He added that the strain has evolved from last year’s version, so immunity from previous infections and even the vaccine may offer less protection.

He also pointed out that fewer people have been exposed to flu in recent years, especially children. This means a larger portion of the population is susceptible. Cold weather, indoor gatherings and normal social habits are also helping the virus spread more easily.

Experts have already noted that this strain picked up seven new mutations over the summer, making it quite different from previous versions in the current vaccine.

With winter underway, the UK is preparing for a rise in flu related deaths. NHS leaders have issued a strong appeal for people to get vaccinated. Last winter saw around 8,000 deaths linked to flu. This was higher than the previous year’s 3,500 deaths but lower than the 16,000 recorded in the 2022 to 2023 season.

How can you protect yourself?

Dr Aragona said getting the flu vaccine is the most important step, especially for people who are older, pregnant, very young or managing long term health conditions.

He said the vaccine does not prevent every infection but it greatly reduces the chances of severe illness and hospitalisation.

Good hand hygiene, covering your mouth and nose when coughing or sneezing, avoiding close contact with sick individuals and keeping indoor spaces well ventilated can also help.

New data from the UKHSA shows the 2025 to 2026 vaccine is currently 70 to 75 per cent effective at preventing hospital visits in children aged two to seventeen, and 30 to 40 per cent effective in adults.

Dr Jamie Lopez Bernal of the UKHSA said the early results offer reassuring evidence that this year’s vaccine provides meaningful protection. He encouraged everyone eligible to get vaccinated as soon as possible.

Dr Thomas Waite, deputy chief medical officer, said flu can be unpleasant for many people and dangerous for some. He emphasised that vaccination is the best defence. He said the season has started early and that those eligible should get their vaccine now.

Last year’s flu vaccine significantly reduced the number of severe cases, cutting hospitalisation by nearly 40 per cent in people over 65 and by 75 per cent in children aged two to seventeen.

How worried should we be about H3N2?

Dr Aragona said that while flu can be uncomfortable, most healthy adults and children recover without complications. He advised against panic but highlighted that older people, those with chronic illnesses and other vulnerable groups could face more serious illness this season.

He said the key is staying alert, getting vaccinated, taking sensible precautions and seeking medical help early if symptoms worsen. With these steps, he said the risks can be managed, even in a year with higher flu activity.

Officials in California have now urged people to not forage for wild mushrooms after a rise in poisoning cases that caused at least one death. The California Poison Control System was able to identify at least 21 cases of poisoning in northern California. This has resulted from death cap mushrooms, confirmed the state's public health department.

How Bad Is The Mushroom Poisoning?

The poisoning has resulted in severe liver damage in people and have not spared even children. It has killed at least one of the patients who may have needed a liver transplant, confirmed the health department.

The problem is that death cap mushrooms could be easily mistaken for safe, edible mushrooms because of its similar taste, smell, and appearance.

What Do Health Officials Say?

Health officials have confirmed that the recent cases occurred between mid November and early December, a period marked by heavy rainfall in the region. The wet weather creates perfect conditions for the toxic death cap mushroom to thrive, especially around oaks and other hardwoods, including pine trees, according to the California Department of Public Health (CDPH).

While most cases have been concentrated in Monterey and the San Francisco Bay Area, the CDPH cautioned that the danger extends across California.

“Death cap mushrooms contain toxins that can cause life threatening liver failure,” said Dr Erica Pan, CDPH Director and State Public Health Officer. “Because these mushrooms can be easily confused with edible varieties, we strongly urge the public to avoid foraging for wild mushrooms during this high risk season.”

The agency stressed that death caps are unsafe under any circumstances. Cooking, freezing, boiling or drying them does not remove their toxicity.

Consuming the mushroom can trigger symptoms such as nausea, vomiting, watery diarrhoea, abdominal pain and dehydration within six to 24 hours. Although the discomfort may briefly subside, serious or even fatal liver damage can develop up to eight days later.

“Only individuals with significant expertise in identifying wild mushrooms should eat those they have harvested themselves,” Dr Edward Moreno, Health Officer for Monterey County, said.

Ways To Identify Death cap Mushroom

Inspect the cap: look for a green or yellow tint on top of the mushroom's white cap. The caps of mature mushrooms also have 1 to 2 large cracks running across them. Death caps often have 1 or more patches of thin, white, vein-like tissue.

A flat cap with diameter 3 to 6 inches: mature death caps are widely and nearly flat on top. However, young death caps have an almost spherical, bowl-shaped cap.

Gills underneath cap: the death mushroom cap has thin white gills on the underside of the cap.

Smell: hold the mushroom about 3 inches away from nose and take a sniff. A death cap mushroom shall smell slightly like ammonia or other chemical household cleaners.

Touch: Tap the death cap mushroom lightly so you do not break it off. The caps of death cap mushroom are often sticky and could leave a small amount of adhesive residue.

Look for white spores left behind: place the mushroom cap on a piece of dark colored paper with gills facing downward. Let the mushroom sit in this position and next morning lift up the mushroom cap and look for white spore print on the sheet. A death cap mushroom will leave a white spore print.
