Cigarettes with ultralow nicotine levels are now being called the game-changer in the fight against smoking. If you are having trouble in quitting smoking, then, it is for you, that soon the Biden White House is expected to formally propose a plan that will order cigarette nicotine levels to be reduced, reports The Washington Post. For now though, it has been a failure, as these cigarettes, also known as VLN cigarettes that stands for very low nicotine are only available in 5,100 stores in 26 states. This is a very small fraction of the overall market for cigarettes. The company that makes it, 22nd Century, is struggling not because of the low supply, but also from the advocates who have long believed slashing nicotine levels altogether.

The Advent and ideation

Nicotine is a chemical that is produced naturally from tobacco that makes the cigarette and also keeps people hooked. While it is believed that it makes people alert, and get the "hit" to keep them going, it exposes the users to harmful substances, carcinogens, and increases the risk of heart disease, lung cancer, and other illness.

Ultralow-nicotine cigarettes, like the VLN brand, contain about 95% less nicotine than the regular cigarettes. The idea is quite simple: without the addictive grip of nicotine, smokers will find it easier to quit. Research too has shown some promise. For instance, the studies funded by the National Institute on Drug Abuse revealed that very low nicotine cigarettes reduced addiction potential significantly without having users to increase their smoking frequency. However, the problem is, why would anyone choose for a low-nicotine that does not make them feel the same way, when the high-nicotine cigarette is right next to it, making them feel the same way, with the same alertness, sold at the same price.

“It’s very hard to imagine someone actively choosing to continue to use a low-nicotine product for the same price when a high-nicotine product is right next to it,” said Eric Donny, a Wake Forest University School of Medicine nicotine researcher.

No wonder, the experiment with low nicotine product by Philip Morris' Next cigarettes in the 1980s and Vector Tobacco's Quest brand in the early 2000s, flopped.

FDA's Role in the Push

The Food and Drug Administration (FDA) has supported the development of such products, even allowing VLN cigarettes to be marketed as lower-risk options. However, these products remain a niche market, available in only a fraction of U.S. stores.

Recently, the Biden administration has considered a bold step—mandating a dramatic reduction in nicotine levels for all cigarettes sold in the United States. Supporters believe this move could save millions of lives, while critics, including tobacco companies, warn of potential unintended consequences.

What Could Be The Challenges?

Resistance from Big Tobacco Companies: They could argue that slashing nicotine levels could backfire. Their claim is, smokers will turn to black markets or smoke more to satisfy their cravings, which may lead to greater exposure to harmful substances.

Consumer Reluctance: History is proof to the instances of smokers being hesitant to embrace the low-nicotine products.

Political Hurdle: It may face political roadblocks, as under the Trump administration, plans to cut nicotine were shelved.

Could Low-Nicotine Cigarettes Be The Solution?

Advocates believe that ultralow-nicotine cigarettes could be a game-changer, comparing them to decaf coffee or non-alcoholic beer—products that reduce harm while offering a similar experience.

Some experts warn that a black market for traditional cigarettes could undermine these efforts. They also stress the need for safer alternatives, such as vaping products, to support smokers transitioning away from traditional cigarettes.

Women diagnosed with polyendocrine metabolic ovarian syndrome (PMOS) should receive an annual NHS health review and be diagnosed earlier to reduce their long-term health risks, according to draft guidance released by the UK's National Institute for Health and Care Excellence (NICE).

The guidance, now open for public consultation, recommends yearly reviews to monitor symptoms, treatment and the risk of developing serious conditions such as type 2 diabetes and cardiovascular disease. Earlier diagnosis, NICE says, could help people access timely care and make lifestyle changes before complications develop.

PMOS, until recently known as polycystic ovary syndrome (PCOS), was renamed following an international consensus published in The Lancet. The new name better reflects the condition's endocrine, metabolic and ovarian features.

What Does The Draft Guideline Recommend?

NICE recommends that everyone diagnosed with PMOS should be offered an annual review covering:

• Menstrual irregularities
• Symptoms such as excess hair growth (hirsutism)
• Medication use
• Screening for long-term health risks, including diabetes and cardiovascular disease

The guideline also includes recommendations on fertility treatment, stating that eligible patients should be offered IVF in line with existing NHS fertility guidance. It also addresses the management of common PMOS-related conditions, including acne, hirsutism and obstructive sleep apnea.

Given the increased risk of metabolic and cardiovascular disease in people with PMOS, the guidance directs healthcare professionals to relevant NICE recommendations for managing these conditions.

Earlier Diagnosis A Key Priority

The draft guideline highlights that PMOS remains underdiagnosed despite affecting an estimated one in eight women.

It recommends investigating PMOS in anyone with irregular or absent menstrual cycles alongside signs of excess male hormones, as these are common indicators of the condition.

The guidance covers girls aged over 10, as well as adult women, trans men and non-binary people who are not receiving gender-affirming hormone therapy or surgery.

People with suspected PMOS should be offered blood tests to measure hormone levels and, where appropriate, pelvic ultrasound scans. The guideline also states that PMOS should not be ruled out after menopause and notes that the condition may be more prevalent among women of Black, Asian and mixed ethnic backgrounds.

Marie Anne Ledingham, consultant clinical adviser for women's and reproductive health at NICE, said the guidance is intended to improve consistency of care and ensure people receive appropriate long-term monitoring.

"PMOS is a common but often overlooked condition that can have a major impact on health and well-being. Recommending a simple annual review is an important step towards ensuring people get the ongoing care and monitoring they need," Ledingham said, in a statement.

Mental Health And Fertility Addressed

The draft guidance recognizes that PMOS affects far more than reproductive health. It is associated with an increased risk of depression, anxiety, eating disorders, fatty liver disease, obstructive sleep apnoea, pregnancy complications and fertility problems.

For people planning a pregnancy, NICE recommends advice on achieving and maintaining a healthy weight, balanced nutrition, regular exercise, good sleep and mental wellbeing to improve reproductive outcomes.

The guidance also stresses that eating disorders should not be overlooked or dismissed based solely on a person's weight.

Laser Hair Removal Not Recommended

While the draft guideline includes recommendations to manage hirsutism, it does not support routine NHS funding for laser and light-based hair removal therapies. NICE concluded that these treatments are not cost-effective, estimating they could cost the NHS "up to £100 million annually" in England if routinely funded.

The draft guideline is open for consultation until August 11, 2026, with the final NICE guidance on PMOS expected to be published in December 2026.

The Centers for Disease Control and Prevention (CDC) has issued a prevention advisory against West Nile virus as the transmission season has begun early and more intensely. As of June 30, the virus has been detected in at least 23 states, with most in Arizona, making this season the widest geographic spread this early in the season in a decade.

West Nile Virus: CDC Issues Warning Against Mosquito Bites

At least 48 confirmed cases of West Nile virus were reported in the US. 38 of them are neuroinvasive (severe) cases, making it the strongest season in two decades.

Arizona has recorded the highest number of infections, particularly in Maricopa County, where 32 cases and four deaths have been reported. The first case of 2026 emerged in California’s Long Beach.

Authorities have warned, saying that senior citizens and people with weakened immune systems remain at the highest risk.

The CDC has issued a prevention advisory to control West Nile virus. It includes:

• Use mosquito repellents containing DEET, picaridin, or oil of lemon eucalyptus.

• Wear long sleeves and long pants.

• Remove stagnant water around the house to remove mosquito breeding sites.

• Repair damaged window and door screens.

• Seek medical care if you have a high fever, severe headache, confusion, neck stiffness, or muscle weakness, especially if it develops after mosquito exposure.

About West Nile Virus

West Nile virus (WNV) is a mosquito-borne virus that belongs to the flavivirus family, the same group that includes the viruses causing Dengue fever, Zika virus disease, Yellow fever, and Japanese encephalitis.

It is primarily spread through the bite of an infected Culex mosquito. Mosquitoes become infected after feeding on infected birds, which are the virus's first host. About 80% infected with West Nile virus have no symptoms. About 20% develop West Nile fever.

Its common symptoms include:

• Fever

• Headache

• Body and muscle aches

• Fatigue or weakness

• Joint pain

• Nausea or vomiting

• Diarrhea

• Skin rash on the trunk or back

• Swollen lymph nodes

The disease could become serious in a few infected people who may develop its neuroinvasive disease. In this situation, the virus affects the brain, spinal cord, or surrounding tissues. Severe complications include encephalitis (brain inflammation), meningitis, and acute flaccid paralysis.

The symptoms of severe West Nile virus include most of the commons ones as well as:

• Neck stiffness

• Confusion or disorientation

• Tremors

• Loss of coordination

• Vision problems

• Seizures

• Paralysis

• Coma (rare cases)

Why The West Nile Virus Season Is Early This Year?

Prolonged Warmer Climate

Mosquito populations usually do not thrive in cold weather. A warmer winter in several parts of the U.S. meant more mosquito populations survived into spring, leading to early breeding and virus transmission.

Warm Temperatures Accelerate Mosquito Breeding

Warm spring weather speeds up mosquito breeding. The virus becomes active enough to reach infectious levels in warmer mosquitoes, shortening the time between when a mosquito becomes infected and when it can spread the virus to humans.

Stagnant Water

In most regions, warm weather is followed by periods of rain, creating ideal habitats for mosquitoes to breed.

Climate Change Extend Mosquito Seasons

Longer mosquito seasons are usually due to a milder-than-average warm climate. Warm temperatures also help the mosquito population to expand in newer regions. This leads to faster viral development and more cases of infection.

Ugandan health authorities have confirmed an isolated case of Marburg virus disease (MVD) in a young child who died from the highly infectious viral hemorrhagic fever.

The case comes as Uganda is already battling an outbreak of Ebola virus disease, another viral hemorrhagic fever.

According to the Africa Centres for Disease Control and Prevention (Africa CDC), the Marburg infection was detected during surveillance for the ongoing Ebola outbreak, Reuters reported.

Health officials said no contacts of the child have developed symptoms, and there are currently no active Marburg cases in the East African nation.

While a spokesperson for Uganda's Ministry of Health said they were unaware of a Marburg outbreak, the World Health Organization (WHO) confirmed it was notified of the case on June 30.

"WHO has requested further information and is supporting the local response, including case investigation, active case finding, contact tracing and community engagement," a WHO spokesperson said.

Child Death Raises Questions

According to Africa CDC, the case was identified in Kyegegwa district in western Uganda in a 1½-year-old child who later died.

"Africa CDC is engaging the Government of Uganda through official public health channels on reports concerning Marburg virus disease. At this stage, we cannot confirm reports of any additional case," Africa CDC spokesperson Saran Koly said.

"Africa CDC stands ready to support verification, risk assessment and response readiness as needed."

Uganda last reported a Marburg outbreak in 2017 and has experience of managing three previous outbreaks. However, responding to a potential Marburg outbreak while simultaneously battling Ebola could complicate public health efforts.

So far, Uganda has reported a total of 20 cases of the rare Bundibugyo species of Ebola, including two deaths. Of these, 15 cases were imported from the Democratic Republic of Congo.

Marburg Infection In Child 'Unusual'

The child's age has prompted questions about how the infection occurred. Abraar Karan, a global health physician and researcher at Stanford University, said infection in a toddler is unusual.

"Quite unusual -- I would suspect transmission from someone else, but there are some less-likely scenarios in which spillover could still have happened directly to a toddler," he wrote in a post on X.

What Is Marburg Virus Disease?

Marburg virus disease belongs to the same virus family as Ebola and can cause severe hemorrhagic fever. It was first recognized in 1967. MVD has a high case fatality rate ranging from 32 per cent to 88 per cent. It is transmitted to humans after a spill-over event from a wildlife reservoir such as Rousettus aegyptiacus fruit bats or their feces or contact with infected primates

Once a person is infected, the virus spreads through direct contact with the blood, bodily fluids or contaminated materials of an infected person.

Common Signs and Symptoms

Symptoms usually begin suddenly and include:

• High fever
• Severe headache
• Muscle pain
• Diarrhea
• Vomiting
• Abdominal pain
• Extreme weakness

In severe cases, patients may develop internal and external bleeding, organ failure and shock, which can be fatal.

How Can Marburg Virus Be Prevented?

There is currently no approved vaccine or specific treatment for Marburg virus disease, although several vaccines and therapies are under development. Early supportive care can improve survival.

Health authorities recommend:

• Avoid direct contact with the blood and bodily fluids of infected people.
• Avoid handling the bodies of people who died from Marburg virus disease.
• Avoid close contact with bats and wild animals, and do not handle bushmeat.
