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.

Individuals who experience tingling, numbness, and burning sensations in their hands and feet often disregard these early symptoms, especially after a long drive, extended standing, or sleeping. Many frequently take painkillers to ease their discomfort in the hope that their pain and other symptoms will quickly go away.
These types of persistent or recurrent symptoms, however, could be a signal of a nerve health issue such as peripheral neuropathy. Vitamin B12 is crucial for the nervous system, and its deficiency could be one of the potential causes.
Early detection of these symptoms and appropriate, timely medical advice can help facilitate immediate intervention. Addressing nutritional gaps under medical guidance may help support overall nerve health and reduce the risk of progression.
Neurotropic B-vitamins are essential for preserving the structure and function of nerves. A lack of these vitamins may present as:
Common Vitamin B12 deficiency signs include persistent fatigue, sensory disturbances, imbalance and neuropathic discomfort. Early detection supports timely intervention and may help prevent further nerve damage.
The right nutritional support plays a key role in preserving nerve function:
An appropriate and active approach to nerve care includes nutritional adjustments, metabolic regulation, and the right assistance to support symptoms.
Dietary Optimization: Encourage intake of foods rich in B-vitamins such as whole grains, dairy, eggs, legumes, and leafy vegetables. However, for those with restrictions, the diet alone might not be enough, especially in cases of established deficiency, malabsorption, or restricted diets.
Targeted Treatment: When guided by a healthcare professional, oral supplementation can be considered as part of a comprehensive plan.

Dozens of food products, including chocolates, snack mixes, popcorn, chips, and nuts, have been recalled in the US over the risk of salmonella contamination.
The recall is due to a specific ingredient — milk powder supplied by California Dairies — used in several products and snacks, particularly in seasonings.
According to the Food and Drug Administration (FDA), the potentially tainted powdered milk and buttermilk were voluntarily recalled on April 20.

The FDA urges people who purchased the products to throw them away or return them for a refund.
A separate Salmonella recall impacting 12 flavors of the popular chocolate brand Spring & Mulberry was also recently announced by the FDA, but appeared to be linked to a date supplier. It wasn't immediately clear if there was any connection to the California Dairies recall.
Another is a public health alert issued by the US Department of Agriculture’s Food Safety and Inspection Service (FSIS) for headcheese over possible contamination with Listeria monocytogenes (Lm).

As per the US Food and Drug Administration (FDA), Salmonella is a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis. It can be spread by food handlers who do not wash their hands and/or the surfaces and tools they use between food preparation steps. It can also happen when people consume uncooked and raw food. Salmonella can also spread from animals to people.
The FDA notes that people who have direct contact with certain animals, including poultry and reptiles, can spread the bacteria from the animal to food if hand washing hygiene is not practiced.
Pets, too, could spread the bacteria within the home environment if they eat food contaminated with Salmonella.
Common symptoms of Salmonella include
Children younger than 5, adults 65 and older, and people with weakened immune systems are more likely to have severe illness.

Ivermectin, an antiparasitic medication, which gained widespread attention during the COVID-19 pandemic, is back in the spotlight again — this time in connection with the ongoing hantavirus outbreak linked to the MV Hondius.
According to the latest update from the World Health Organization (WHO), nine hantavirus cases have been confirmed so far, including three deaths.
Health authorities have also confirmed that the outbreak involves the Andes strain of hantavirus — the only known hantavirus strain capable of human-to-human transmission.
While global health agencies, including the WHO, Centers for Disease Control and Prevention (CDC), and the European Centre for Disease Prevention and Control (ECDC), continue to maintain that the overall public health risk remains low, memories of the COVID-19 pandemic and the disruption it caused remain fresh. As a result, fear, speculation, and misinformation are once again spreading rapidly online.
"Hantavirus is an RNA virus, and ivermectin should work against it," claims a May 6, 2026, post on X from Mary Talley Bowden, an ear, nose, and throat doctor suspended in 2021 by Houston Methodist Hospital for spreading Covid-19 misinformation.
"I actually texted her today and asked what we can treat hantavirus with. I'm so glad she posted it," former Texas representative Marjorie Taylor Greene wrote on X as she amplified Bowden's assertions about ivermectin.
HealthandMe spoke to experts to understand the truth behind these claims, and they dismissed the misinformation surrounding them stat.
Dr Jatin Ahuja, Consultant, Infectious Disease, Apollo Delhi, noted that, "there is currently no strong scientific evidence or official guideline supporting ivermectin as a proven treatment for hantavirus in humans".
He advised people to avoid self-medication or depending on unverified online claims and to consult a doctor at the earliest if they experience any symptoms.
Dr Rajiva Gupta, Senior Consultant, Internal Medicine, CK Birla Hospital, Gurugram, added that ivermectin is not approved for the treatment of hantavirus infection by major global regulatory and public health agencies, including the World Health Organization, Centers for Disease Control and Prevention, or the US Food and Drug Administration.
"Current claims linking ivermectin to hantavirus treatment appear largely unverified and are being circulated primarily through social media platforms," he told HealthandMe.

Ivermectin is a well-established medication that is highly effective against parasites. It was developed to treat topical parasitic infections and has been widely used for conditions like river blindness and scabies.
The drug's significance in treating these diseases was so profound that researchers who studied it won the Nobel Prize in 2015.
The US Food and Drug Administration (FDA) has approved ivermectin tablets for treating specific parasitic infections in humans. It is also available as a lotion to treat lice and as a cream for rosacea. Additionally, veterinarians also use it to prevent and treat parasitic diseases in animals.
Previously, ivermectin also gained popularity as a cancer cure, although there is no scientific evidence for it.
To understand the treatment for hantavirus, let us first look at how the rat-borne virus affects the body.
"Once hantavirus enters the body, it mainly affects the lungs and small blood vessels," Dr Jatin told HealthandMe.
In some patients, the infection can cause fluid build-up in the lungs, which may lead to breathing problems and low oxygen levels.
Further, the severity of symptoms also can vary from person to person and may depend on factors such as the amount of virus a person was exposed to, the body’s immune response, and how early treatment is started.
Like many viral infections, a higher viral load may sometimes be linked to more severe illness, although every patient can respond differently, the experts said.

One challenge with hantavirus is that the early symptoms are quite non-specific and may resemble several common viral or respiratory infections.
Fever, body ache, fatigue, headache, nausea, and cough are commonly reported in the initial stage. In a few cases, symptoms may progress to breathing difficulty and lung-related complications, which require timely medical care.
Currently, treatments focus on medical care support and managing complications at the earliest stage possible.
"Patients may require oxygen support, hydration, monitoring, and intensive care depending on the severity of the illness. Early recognition and prompt medical attention remain important for better outcomes," Dr Jatin said.
Dr Rajiva noted that approved management for hantavirus infection remains primarily supportive, focused on respiratory and hemodynamic (circulatory) support. Among the therapies explored so far, ribavirin and monoclonal antibodies have shown some potential in experimental settings and animal models, but these are still under investigation and are not widely approved as standard treatment options.
