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.

Measles cases continue to rise rapidly in Bangladesh, with confirmed infections nearing 10,000 and hundreds of deaths reported since the outbreak began in March this year.

The Directorate General of Health Services (DGHS) reported 1,092 additional measles cases in the past 24 hours, bringing the country's total to 80,104 cases, including 9,779 confirmed infections, since March 15, according to The Outbreak Today.

Eight additional deaths were also reported, taking the total death toll to 628, including 92 confirmed measles-related fatalities.

A total of 65,237 suspected measles patients have been hospitalized, of whom 61,278 have recovered, according to the DGHS.

The capital city, Dhaka, remains the epicentre of the outbreak. Health authorities have reported approximately 37,387 suspected measles cases and 6,794 confirmed cases across the wider Dhaka Division.

“There is no sign of a downtrend in measles infection rate across the country,” Dr. Ariful Bashar from Mohakhali Contagious Disease Hospital told Arab News.

“Measles is a highly contagious disease, even six times more than COVID-19. Unless 95 percent immunity is achieved through vaccination, there will be no downtrend in the infection rate,” he added.

Since March, hospitals across the country have been overwhelmed as they struggle to isolate and treat hundreds of children admitted every day.

Four out of five measles patients are younger than five years, according to The New York Times. The vast majority of deaths have also occurred in this age group, which is highly vulnerable to the airborne virus.

According to the United Nations International Children's Emergency Fund (UNICEF), Bangladesh had largely contained measles outbreaks since the 1990s through vaccination campaigns. However, immunization efforts were disrupted in 2024 after student-led protests overthrew the government.

The interim administration that governed Bangladesh until elections in late February did not conduct a supplementary mass vaccination campaign as recommended.

Last week, UNICEF said it had repeatedly warned the country’s interim government, led by Muhammad Yunus, through written communications and meetings with Health Ministry officials about vaccine shortages that could trigger a major health crisis, local media reported.

In April, Bangladesh’s new government launched an emergency campaign to vaccinate 20 million children.

Although the campaign has reportedly achieved 110 percent of its target and remains ongoing, experts note that only one of the two doses required for strong and durable immunity has been administered so far. In addition, it takes four to six weeks for immunity to develop after vaccination.

Outbreak Spreads Nationwide

The outbreak began in January in Rohingya refugee camps near the Myanmar border and quickly spread nationwide. It has now reached 58 of Bangladesh’s 64 districts, causing more than 21,000 hospitalizations.

In an April 23 update, the World Health Organization (WHO) warned of a “considerable risk” of spread to Myanmar, where civil strife has disrupted immunization efforts, and to India, which remains vulnerable. WHO described the outbreak as “a reversal from Bangladesh’s previous progress towards measles elimination.”

Kerala is battling a highly contagious bacterial disease called shigellosis (bacillary dysentery), caused by the bacteria Shigella. The southern state has recorded 85 cases of the intestinal infection called shigellosis since the beginning of this year.

All districts in the state have reported sporadic cases of the disease, which is primarily caused by contaminated food and water or poor hygiene practices.

Currently, cases have been reported from northern districts such as Wayanad, Kozhikode, Alappuzha, and Malappuram.

This week, two cases involving a four-and-a-half-year-old boy and a five-year-old girl were confirmed among children at Mar Baselios School in Wayanad.

About 25 students with suspected Shigella infection have been admitted to the Sultan Bathery Taluk Headquarters Hospital. However, Kerala Health Minister K. Muraleedharan said their conditions are stable, ANI reported.

Earlier, a four-year-old girl undergoing treatment at Kozhikode Medical College died after being infected with Shigella.

According to health authorities, 339 people have reported symptoms associated with the infection. Of these, 21 are undergoing treatment at Sultan Bathery Taluk Headquarters Hospital, while 38 others are receiving treatment at private hospitals.

Officials said none of the patients is currently in serious condition. A total of 21 samples were sent for laboratory testing. Two samples have tested positive so far, while the results of the remaining samples are awaited.

Muraleedharan also asserted that the Shigella outbreak reported in parts of the state remains under control, even as health authorities continue monitoring cases in Wayanad and other districts.

The Health Minister noted that a special medical team from Kozhikode Medical College has been deployed to Wayanad, where several students were admitted to hospital following reports of shigellosis, a highly contagious bacterial intestinal infection.

Shigella: Why Are Young Children at High Risk?

Speaking to HealthandMe, Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala, explained that even a small number of bacteria—as few as 10—is enough to cause infection.

It is because the Shigella bacteria “is able to withstand the hostile acidic environment of the human stomach. Outside the human body, it can stay alive in water for weeks together,” he said.

Shigella is most severe in children below the age of five, as their immune systems are less efficient at clearing the infection early.

“Adults also become ill, but acquired immunity from childhood keeps the infection mild in many instances,” the expert said.

How Does Shigella Spread?

Shigella spreads through:

• Touching contaminated surfaces or objects
• Physical contact with an infected individual
• Drinking contaminated water or ice made from unclean water

“Shigella outbreaks can occur in crowded places such as anganwadis, where children come into close physical contact with each other and share toys. Very young children also have the habit of putting their fingers in their mouths, which enables the bacteria to gain access to their gut,” Dr. Jayadevan said.

The expert noted that houseflies can also spread the bacteria. Flies transmit the bacteria from human feces to food, water, and surfaces, contributing to up to 37 percent of cases in some regions, according to a study published in PLOS Neglected Tropical Diseases.

Shigella: What Are the Symptoms?

The disease typically develops within one to three days after ingestion of the bacteria and may begin with:

• Fever
• Diarrhea
• Body aches
• Headache

Once the infection involves the large intestine, bloody diarrhea can occur along with severe abdominal cramps.

How to Prevent Shigella

Dr. Jayadevan stressed the need for early recognition and treatment with appropriate antibiotics. ORS can help prevent dehydration, while zinc tablets can enhance recovery.

Other measures to reduce the risk of spread include:

• Washing hands with soap and water, especially before touching food and after using the toilet
• Maintaining hygiene among food handlers
• Controlling flies.

From 130 maternal deaths per lakh live births during 2014–16, India has achieved a 43-point reduction in the Maternal Mortality Ratio (MMR) between 2022 and 2024, according to the government.

Currently, the MMR in the country stands at 87 maternal deaths per lakh live births.

In an official statement, the government credited the achievement to Pradhan Mantri Surakshit Matritva Abhiyaan (PMSMA), which today completed a decade.

Launched in June 2016, PMSMA provides free, comprehensive antenatal care to pregnant women at designated government health facilities on the 9th of every month.

More than 7.50 crore pregnant women have received antenatal services under PMSMA in addition to routine ANC check-up services in the last 10 years. The Extended PMSMA, launched in 2022, strengthens follow-up care and tracking for high-risk pregnancies.

"Over the past decade, the Pradhan Mantri Surakshit Matritva Abhiyaan has transformed the delivery of antenatal care in India. Quality maternal healthcare is now more accessible, systematic and responsive," the statement said.

“The remarkable decline in the Maternal Mortality Ratio from 130 to 87 over the past decade demonstrates how focused interventions can save thousands of lives,” it added.

How PMSMA Works

The government noted that PMSMA works through:

• Early identification of high-risk pregnancies
• Regular monitoring
• Timely medical intervention

"PMSMA has demonstrated that when quality healthcare reaches women at the right time, it saves lives, prevents complications and creates healthier beginnings for families and future generations," the govt said.

Services Offered Under PMSMA

The PMSMA service package includes clinical examinations, laboratory investigations (blood and urine tests), ultrasonography, medicines, and counselling on nutrition, birth planning, and safe pregnancy practices.

Key features include:

• Minimum one comprehensive and quality antenatal check-up by an Obstetrician and Gynecologist or a Comprehensive Emergency Obstetric and Newborn Care (CEmONC) trained doctor during the second or third trimester.
• Mobilizing pregnant women for specialist antenatal care services at designated public health facilities.
• High-risk pregnancy identification by screening for 25 high-risk factors and management at an early stage.
• Linking high-risk pregnancies to the nearest First Referral Unit (FRU) for safe delivery.
• Empanelment of private service providers for PMSMA service provision.
• Essential blood and urine investigations and ultrasonography.
• Counselling on nutrition, appropriate birth planning, and complication readiness for every pregnant woman.

Who Can Access PMSMA Services?

The program is available to:

• Pregnant women in their second trimester (13–27 weeks) or third trimester (28 weeks until delivery).
• Indian citizens residing in India who are willing to visit designated government health facilities on the 9th of every month.
• High-risk pregnancy cases, which receive priority attention and follow-up care.
• Women who are dropouts from regular antenatal care and are actively encouraged to participate.

What Is Maternal Mortality Ratio?

MMR is defined as the number of maternal deaths per one lakh live births during a given period.

A maternal death refers to the death of a woman during pregnancy or within 42 days of termination of pregnancy due to causes related to or aggravated by the pregnancy or its management, excluding accidental or incidental causes.

Maternal health remains one of the clearest indicators of the strength and inclusiveness of a country's healthcare system.

"As India marches towards Viksit Bharat@2047, PMSMA will continue to transform the maternal healthcare landscape by ensuring that every pregnancy is safer and every mother receives the care she deserves. With continued commitment and collective action, PMSMA can help usher in an era where no woman loses her life while giving life, strengthening the foundations of a healthier and more prosperous India," the statement said.
