Mosquitoes Bite Some People (Credit-Freepik)
Mosquitoes are a big part of the ecosystem, but often are a nuisance as they bite and feed off of us. Their bites cause itchy red bumps and spread infections and allergies in our bodies. But have you ever wondered why they bite certain people more than others? While some people are plagued by mosquito bites, others barely notice them. Here are some interesting facts about mosquitoes that you must know about!
1. Carbon Dioxide:
Mosquitoes are attracted to a certain smell that emits from the human body that is present in the human skin and sweat, mosquitoes can sense the carbon dioxide or CO2 we breathe out. The more active you are, the more CO2 you emit and the more mosquitoes will be attracted to you. Researchers are still investigating the cause of the variation of body odour that brings them to you, possibly genetics or certain bacteria. The unique combination of sweat and skin bacteria creates a scent that mosquitoes find irresistible. Some chemicals in sweat, like lactic acid and ammonia, are especially attractive to them.
2. Colours
While the reason isn't fully understood, mosquitoes seem to be drawn to dark colours like black more than lighter ones. So, ditch the dark outfit next time you're in mosquito territory. It has been noted that mosquitoes are more likely to leave lighter colours alone.
3. Heat and Vapour
Mosquitoes can detect your body's heat and water vapour, acting like a beacon guiding them right to you. So next time you're feeling sweaty, be aware you might be attracting a lot of mosquitoes. If you are working out or doing something that is making you sweat and your body heat rise, the mosquitoes nearby will be instantly attracted to you. Even mosquitoes are careful about who they pick as a host, some studies even suggest that they like a certain body temperature to feed off of.
An interesting fact about mosquitoes is that they can learn to like a host. They have their own preferences and if they meet a certain person who fits their criteria they might be the next host they move onto. In an older study, it showed that 20 per cent of people with mosquito-borne diseases accounted for 80 per cent of diseases transmitted in the population. They suggest that they only bite a certain set of people within the population.
4. Other factors:
Studies suggest mosquitoes might learn to prefer certain people based on things like what you've been drinking. In a 2002 study, there could be many reasons they like alcohol to making your body temperature high etc. Even pregnant women seem to be extra attractive to them due to higher body temperature and CO2 output.

US President Donald Trump's attempt to clarify the meaning of "sea" while discussing drug smuggling has again raised concerns of dementia.
While the 79-year-old President rambled between “sea and see” in the middle of discussing drug problems in the US, social media went rife with the rumor of his cognitive decline.
"Drugs coming by sea meaning coming by water. A lot of people don’t know what I mean by sea. They think I mean vision. I’m talking about sea like the sea," he said. He was speaking at the White House, while hosting law enforcement officials for a dinner in the Rose Garden in celebration of National Police Week.
His comments were called out by social media as his apparently worsening cognitive capabilities.
"When he says 'a lot of people' he means 'me.' His cognitive issues are a crisis," one social media user declared, while another admitted, "He’s getting worse."
Trump has spoken on sea and see, during a maternal healthcare event last week, where he also referred to himself as the “father of fertility.”
Earlier, speaking at the White House Small Business Summit, Trump said he has taken the Montreal Cognitive Assessment three times and “aced each one,” claiming a doctor told him it was the first time they had seen a perfect score, The Daily Beast reported.
The US President said he answered the test questions easily, suggesting he is cognitively in good condition—a claim that critics have repeatedly questioned.
“The first question is very easy,” he said. “You have a lion, a bear, an alligator, and a—what’s another good…? A squirrel. Which is the squirrel?” He added that the difficulty increases as the test progresses. “By the time you get to the middle, they’re very tough.”
However, the test’s creator, Canadian neurologist Ziad Nasreddine, has challenged Trump’s claims. “It wasn’t designed to be a test of IQ,” he told nine.com.au. “It was designed to assess normal cognitive performance.”

A group of medical experts, including neurologists, psychiatrists, and other physicians, has sounded the alarm over what they’ve described as Trump’s deteriorating mental health.
The experts have not specifically examined Trump face-to-face. But, they analyzed Trump's statements and behaviors over the past year, and stated that he’s “mentally unfit” and must be removed from office “with the greatest urgency” amid the escalating tension around the world, according to their statement published in The BMJ.
“It is our professional opinion that they (Trump's statements) reflect a rapidly worsening, reality-untethered, increasingly dangerous decline,” the experts said.
They also listed some of Trump’s observable serious medical issues, such as “Marked deterioration in cognitive functioning, evidenced by disorganized and tangential speech, rambling digressions, factual confusions, unexplained sudden changes of course in strategic matters, both national and international, episodes of apparent somnolence during critical public proceedings.”

What The White House Says
The White House has continued to say that Trump remains in strong health.
In October 2025, White House physician Captain Sean Barbabella said the president “continues to demonstrate excellent overall health,” AOl.com reported.
"President Trump’s sharpness, unmatched energy, and historic accessibility stand in stark contrast to what we saw during the last administration when Democrats and other lunatics intentionally covered up Joe Biden’s serious mental and physical decline from the American people,” White House spokesman Davis Ingle was quoted as saying to The Daily Beast.

From Polycystic Ovarian Disease (PCOD) to Polycystic Ovary Syndrome (PCOS) and now Polyendocrine Metabolic Ovarian Syndrome (PMOS) — confused about what the changing terminology means for women’s health and treatment?
What was once seen mainly as a reproductive or ovarian disorder is now being recognized as a complex hormonal and metabolic condition that can affect everything from periods and fertility to weight, insulin resistance, heart health, skin, and mental well-being.
To better understand the distinction between the three, let’s look at how the condition has evolved.
The condition, involving irregular periods, infertility, excess facial hair, and enlarged ovaries containing multiple cysts, was first identified as an ovarian or reproductive disorder in the 1930s by American gynecologists Dr. Irving Stein and Dr. Michael Leventhal. It became known as Stein-Leventhal Syndrome.
Over the years, the term PCOD became widely used, especially in countries like India. The name focused mainly on the presence of multiple ovarian cysts seen on ultrasound scans. It was considered a “disease” affecting ovulation and fertility.
Further, in the 1980s and 1990s, experts discovered that the condition involved hormonal imbalances, insulin resistance, weight gain, diabetes risk, and heart health concerns, among others.
Because it affected multiple body systems, PCOS became the medically preferred global term. The word “syndrome” was used to describe a group of related symptoms rather than a single disease.
However, many experts argued that the name still overemphasized ovarian cysts and fertility, and in 2012, the US National Institutes of Health (NIH) officially recommended changing the name, saying it was misleading because:
In 2026, global experts publishing in The Lancet proposed the new name -- PMOS – for the condition affecting more than 170 million women worldwide.
The new term PMOS acknowledges that the condition involves:

The new name aims to explain the condition more accurately and comprehensively.
Polyendocrine means it affects multiple hormones in the body.
Metabolic refers to issues linked to weight, insulin, blood sugar, and heart health.
Ovarian highlights its impact on ovulation and reproductive health.
Syndrome refers to a group of symptoms occurring together.
In simple terms, PMOS is a hormonal and metabolic condition that can affect periods, fertility, skin, mood, weight, and long-term health.
Speaking to HealthandMe, Dr Monika Bhatia Director — Obstetrics & Gynaecology Robotic and Laparoscopic Surgeon Cloudnine Group of Hospitals, said that the earlier name was misleading because the "cysts" in PCOS are not real cysts — they are simply small, arrested follicles.
While the name has changed, the message remains the same.
“Behind every diagnosis is a woman trying to understand her body, hormones, emotions, and health. While this condition may affect periods, fertility, metabolism, skin, weight, or mental well-being differently, one thing remains common — it is manageable with the right guidance,” she said.
The core treatment stays the same as the guidelines for treatment have not changed, but the approach becomes wider.
“So instead of just treating the periods, PMOS is now managed as a whole-body condition involving a multidisciplinary team”.
Will there be any change to evaluation?
Dr Muskaan Chhabra, Fertility Specialist, Birla Fertility & IVF, Lajpat Nagar, told HealthandMe that the new name –PMOS- correctly acknowledges that this is a multisystem condition involving complex interactions between insulin, androgens, and neuroendocrine hormones.
In PMOS, the ovaries are one of several systems involved rather than the primary site of the problem.
This “opens the door to more comprehensive clinical evaluation, earlier and more accurate diagnosis, and treatment approaches that address the full hormonal and metabolic picture rather than a narrow reproductive one,” Dr Muskaan said. It will also “drive more integrated and personalized care”.

Hantavirus has the potential to linger indoors and spread through contaminated dust, especially in rodent-infested, poorly ventilated spaces, according to infectious disease expert Dr. Vasant C. Nagvekar.
So far, 11 people linked to the MV Hondius cruise ship have been affected. While all passengers have been repatriated and quarantined, the World Health Organization (WHO) anticipates that additional cases may emerge based on observed symptoms.

In an exclusive interview with HealthandMe, Dr. Vasant, a Consultant in Infectious Diseases and Internal Medicine at Lilavati Hospital and Research Center, Mumbai, explained how the virus can spread even within indoor environments. He noted that contaminated dust and surfaces are potential sources of transmission, making proper hygiene and preventive measures crucial.
The expert also stated that the Andes strain rarely transmits person-to-person and emphasized the need for global prevention through enhanced surveillance, early detection, vector control, environmental sanitation, and public awareness, particularly amid urbanization, climate change, and ecosystem disruption.
Here are the excerpts from the interview
Q. How Long Does Hantavirus Survive?
Dr. Vasant: Hantavirus does not survive for long outside a host body and is rapidly inactivated by exposure to sunlight, detergents, and drying.
However, in enclosed indoor environments that are cool with temperatures at 4 degrees Celsius or less, poorly ventilated, and contaminated with rodent urine or feces, the virus may remain infectious for several hours or even longer.
Dr. Vasant: Yes, the virus can be transmitted indirectly through the air. However, hantavirus does not circulate freely in the air in the same way as influenza or coronavirus during normal social interactions.
It becomes airborne when contaminated rodent urine, droppings, or nesting materials are disturbed during activities such as sweeping or cleaning. At that point, the virus can be aerosolized and inhaled by people.
Q. How Can Hantavirus Spread Indoors?
Dr. Vasant: Indoor exposure usually takes place in environments where the presence of goes unnoticed – for example, in cabins, storage rooms, warehouses, inside false ceilings, or vacant rooms.
One could be exposed to hantavirus through inhalation of contaminated dust when a room that has not been used for a while is opened or is cleaned without any protective measures.

The reason why hantavirus exposure is alarming is that it usually takes place during normal activities, which we do without even suspecting anything dangerous.
Q. How Does the Andes Strain of Hantavirus Spread?
Dr. Vasant: The Andes hantavirus stands out because, unlike most other hantaviruses, it exhibits evidence of rare person-to-person transmission, mostly through direct and extended contact between people. As a result, this particular strain is highly interesting for scientists studying infectious diseases around the world and is extensively researched as such. It should be noted, however, that person-to-person transmission is very rare in comparison to respiratory pathogens, such as the influenza virus or SARS-CoV-2.

Dr. Vasant: What is required from our world in terms of the prevention of new viruses is a globally integrated strategy within the public health sector.
Surveillance systems should become more advanced on community levels, especially when there are high risks of increased contact between humans and animals because of urbanization, climate change, and ecosystem destruction.
Early detection, information exchange at the international level, vector control, environmental sanitation, and public awareness are just as significant. New infection strains cannot remain limited to just being a problem of individual countries.
