Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

• Researchers used a new MRI technique to precisely measure brain electrical activity.
• By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
• Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
• MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

An outbreak of Cyclospora, a microscopic parasite that causes prolonged watery diarrhea, has sickened more than 1,400 people across the United States, with infectious disease experts describing the surge in cases as "definitely abnormal."

While the US Centers for Disease Control and Prevention (CDC) is still investigating the source, officials believe the outbreak is likely linked to multiple sources of contamination rather than a single food product.

Health officials in Michigan have reported 1,251 Cyclospora infections, a dramatic increase from around 170 cases recorded on June 30. The state typically reports only about 50 cases annually.

Ohio has confirmed nearly 200 cases, while New York, Illinois, Indiana, North Carolina, and Texas have also reported an increase in infections. More than 40 people have been hospitalized.

Dr. Thomas Moore, an infectious disease specialist and clinical professor of medicine at the University of Kansas School of Medicine-Wichita, described the spike as "definitely abnormal" and concerning, according to The New York Times.

Keith R. Schneider, professor of food safety at the University of Florida, noted that Cyclospora infections usually increase between May and August in the United States. However, he said the current surge—particularly in Michigan—is far beyond what is normally expected.

"Something is going on right now in that area," Schneider told The New York Times.

Experts also warned that the reported infections may represent only the "tip of the iceberg," with additional cases expected in the coming weeks, because the infection takes long to manifest.

What Is Cyclospora And How Does It Spread?

Cyclospora is a microscopic parasite that infects people after they consume food or water contaminated with human feces containing the parasite's eggs (oocysts).

Unlike many foodborne bacteria, Cyclospora infections often takes two days to two weeks or more to cause illness after exposure, making it difficult for investigators to identify the original source.

Although the illness is usually not life-threatening, it can cause prolonged diarrhea, stomach cramps, nausea, fatigue, bloating, and weight loss.

Fresh produce is the most common source of infection, though contaminated water can also spread the parasite. Health officials have not advised people to avoid fresh produce, as investigators have not yet identified the exact food responsible for the current outbreak.

Yet, previous US Cyclospora outbreaks have frequently been linked to imported fresh produce, including:

• Basil
• Cilantro
• Mesclun lettuce
• Raspberries
• Snow peas

Handwashing Matters More Than Hand Sanitizer

Experts emphasize that proper handwashing with soap and water remains one of the most effective ways to reduce the risk of infection.

Alcohol-based hand sanitizers do not kill Cyclospora, making soap and water essential after using the bathroom and before preparing or eating food.

"This type of parasite doesn't easily go away with alcohol-based hand sanitizer. So, good old handwashing is really key here," ABC News medical correspondent Dr. Darien Sutton said.

How To Clean Fresh Produce Safely

While washing produce cannot eliminate all risk, experts say it can reduce contamination. They advised washing fruits and vegetables thoroughly under clean running water, and washing hands before and after handling fresh produce.

According to the Michigan Department of Health and Human Services, cooking produce whenever possible during an active outbreak is crucial, as heating food to at least 158°F (70°C) kills Cyclospora.

For specific produce, it suggested:

• Cilantro and basil: Separate the leaves and rinse each thoroughly under running water.
• Green onions: Trim off the roots, remove the outer layer, and rinse well.
• Snow peas: Rub the surface gently while washing under running water.
• Raspberries: Because of their delicate, uneven surface, raspberries are difficult to clean thoroughly. Cooking them in pies or jams is safer. Freezing may reduce the number of parasites but is unlikely to eliminate them completely.
• Leafy greens: If possible, choose whole heads of lettuce instead of bagged salad mixes. Discard the outer leaves and wash the remaining leaves under running water before eating.

The UK has reported an outbreak of crusted scabies, a rare and highly contagious form of scabies, prompting the temporary closure of a hospital ward in Wales.

According to the Hywel Dda University Health Board, Steffan Ward at Glangwili Hospital in Carmarthen has been temporarily closed while the outbreak is managed under established infection prevention and control measures, according to the BBC.

Health officials said all patients and staff identified as close contacts have been informed and offered treatment, even if they are not showing symptoms. Enhanced infection control measures, including monitoring, treatment of identified contacts, and specialist support, have also been put in place.

Officials added that a recent rise in scabies cases across Carmarthenshire, Pembrokeshire, and Ceredigion has contributed to outbreaks in healthcare settings. The ward will reopen once it is deemed safe under infection control guidance.

Scabies is a highly contagious skin infestation caused by the microscopic mite Sarcoptes scabiei. The mites burrow into the upper layer of the skin, where they lay eggs, triggering an allergic reaction that causes intense itching and a rash.

However, the crusted scabies—previously known as Norwegian scabies—is a severe form of the infestation in which the skin develops thick, crusted plaques that may crack and become inflamed, according to the US Centers for Disease Control and Prevention (CDC).

Unlike classic scabies, patients with crusted scabies may not experience severe itching or develop the typical rash, making the condition more difficult to recognize. However, they can carry up to two million mites and eggs, making them extremely contagious.

Because of the heavy mite burden, crusted scabies can rapidly spread in healthcare facilities and long-term care homes if not identified and treated promptly. It may also lead to serious complications, including secondary bacterial infections and sepsis.

People at increased risk of developing crusted scabies include:

• Older adults
• People with weakened immune systems, including those living with HIV/AIDS
• Individuals with conditions that reduce the ability to itch or scratch, such as spinal cord injuries, paralysis, loss of sensation, or severe neurological or behavioral disorders

How Can Crusted Scabies Be Prevented?

Preventing outbreaks requires rapid diagnosis, prompt treatment, and strict infection control measures.

Health authorities recommend:

• Identifying and treating all close contacts, including household members, caregivers, and sexual partners
• Isolating affected individuals when necessary
• Washing or decontaminating bedding, clothing, and towels used by infected patients
• Maintaining strict hygiene and environmental cleaning in healthcare settings

Why Early Diagnosis Matters

Early diagnosis is critical to preventing further transmission. Since crusted scabies may not present with the classic symptoms of itching and rash, healthcare professionals play an important role in recognizing the condition.

Only a qualified healthcare provider can confirm the diagnosis and prescribe appropriate treatment. Prompt medical care helps reduce the risk of complications and prevents outbreaks in hospitals, nursing homes, and other communal settings.

The Chandipura virus (CHPV), a rare but potentially fatal brain infection, has claimed the lives of three young children in Gujarat and Rajasthan, raising concerns during the ongoing monsoon season when insect-borne diseases become more common.

A six-year-old boy from Rajasthan with a confirmed Chandipura virus infection died at the Civil Hospital in Himmatnagar, Gujarat's Sabarkantha district, officials said on July 9.

According to Resident Medical Officer Dr. Vipul Jani, seven children aged between 2 and 11 years with suspected CHPV infection were admitted to the hospital between June 26 and July 9.

The child with confirmed infection was identified as Rajkumar Damor (6), a resident of Udaipur, Rajasthan.

Two girls—a two-year-old from Rajasthan and a three-year-old from Sabarkantha, Gujarat—are currently undergoing treatment, while laboratory reports are awaited. Another three-year-old boy tested negative and has been discharged.

What Is Chandipura Virus?

Chandipura virus (CHPV) is an insect-borne virus belonging to the Rhabdoviridae family and the Vesiculovirus genus. It was first identified in 1965 in Chandipura village in Maharashtra.

The virus is transmitted primarily through phlebotomine sandflies, although mosquitoes and ticks may also play a role in transmission.

Most cases have been reported from central and western India, particularly during the monsoon and post-monsoon months when sandfly populations increase.

While some infections remain mild, the virus can rapidly invade the brain, causing acute encephalitis (brain inflammation), seizures, coma and even death, especially in children.

"In some children, Chandipura virus can cause severe brain inflammation and become life-threatening within a short period," said Dr. Kanchankumar Bhagyawant, Consultant Paediatrician and Neonatologist at Ruby Hall Clinic, Pune.

Symptoms Of Chandipura Virus Infection

Symptoms usually begin suddenly and may initially resemble other viral illnesses. The expert urged to watch out for:

• Sudden high fever
• Severe headache
• Vomiting
• Excessive sleepiness or reduced activity
• Irritability or behavioural changes
• Convulsions or seizures
• Loss of consciousness in severe cases

"Parents should never ignore a fever lasting more than three days if it is accompanied by repeated vomiting, seizures, confusion or excessive sleepiness. Seeking immediate medical care can be lifesaving," Dr. Bhagyawant said.

Why Are Children More At Risk?

According to Dr. Bhagyawant, children below 15 years, especially those living in rural and semi-rural areas, are the most vulnerable to Chandipura virus infection. Although adults can be infected, severe disease is far less common.

"The Chandipura virus infects young children, leading to inflammation of the brain called encephalitis," Dr. Rajeev Jayadevan, former President of the Indian Medical Association (IMA) Cochin and Convener of the Research Cell, Kerala told HealthandMe.

Children are at greater risk because of several factors:

• Immature immune system: Young children have fewer antibodies and are less able to fight new viral infections.
• Higher exposure: Outdoor play increases contact with sandflies, particularly during the monsoon.
• Limited prior immunity: Most children have not been previously exposed to the virus.
• Rapid disease progression: The virus can multiply quickly, overwhelming a child's immune system.
• Developing brain: Children's brains are more vulnerable to encephalitis and neurological damage.
• Delayed diagnosis: Early symptoms resemble common viral infections, delaying treatment.
• Limited healthcare access: Rural areas may have fewer diagnostic and treatment facilities.
• Poor vector control: Inadequate measures to control sandflies increase the risk of transmission.

How Can Chandipura Virus Infection Be Prevented?

"There are no known anti-virals or vaccines, which means that our treatment is dependent on the patient receiving early medical attention and supportive care. Children are the victims. Vector control, avoiding bites, especially in monsoon seasons is important," Jayadevan said.

Dr. Bhagyawant recommended:

• Use mosquito or sandfly nets, especially for children at night.
• Apply age-appropriate insect repellents.
• Dress children in full-sleeved clothing and long pants.
• Keep homes and surroundings clean.
• Eliminate stagnant water and improve sanitation around homes and animal shelters.
• Install window screens where possible.
• Seek immediate medical attention if a child develops a high fever along with vomiting, seizures or altered consciousness.
