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.

The Ebola outbreak continues to grow, with 2,344 confirmed cases and 930 deaths, according to the latest government update.

In its July 18 situation update, the Ministry of Health said response efforts have been strengthened across the five affected provinces: Haut-Uélé, Ituri, Nord-Kivu, Sud-Kivu, and Tshopo.

“To date, 2,344 confirmed cases have been recorded, including 724 patients in isolation or hospitalization, 466 people recovered, and 930 deaths,” the Ministry said.

The case fatality rate stands at 39.7%, while the contact tracing rate has reached 85.8%. Ituri remains the epicentre of the outbreak and continues to intensify response efforts.

Health teams are continuing surveillance, case management, and contact tracing to contain the spread of the disease.

According to the ministry, surveillance and contact tracing systems remain fully mobilised, with 83 new confirmed cases reported nationwide. Case management has also improved, with 22 new recoveries recorded in the past 24 hours. Sud-Kivu and Tshopo remain stable, with no new affected health zones.

Canada, US Tighten Border Measures

Canada has temporarily denied entry to foreign nationals who have been in Congo within the previous 21 days as part of measures to reduce the risk of Ebola transmission.

"Limiting entry of foreign nationals who have been in (Congo) in the previous 21 days may reduce public health risks for Canadians," Canada's Public Health Agency said in a statement.

However, the World Health Organization (WHO) advises against travel or trade restrictions during Ebola outbreaks, warning that such measures can increase stigma and hamper outbreak control. The global health agency also continues to assess the risk of international spread from the Congo outbreak as low.

Last week, the United States also introduced measures requiring travellers who had been in Congo within the previous 21 days to enter the country only through designated airports. Seven American aid workers who had been working in Congo are currently quarantining in Kenya.

Attacks on Health Workers Hampering Response

Authorities have recorded at least 12 attacks on health facilities and response teams since the outbreak began in mid-May, largely driven by misinformation and public skepticism. Many healthcare workers have also gone on strike over unpaid wages, AP News reported.

At least 36 health workers have died after becoming infected with Ebola. The WHO has also warned that 80% of new Ebola cases are emerging from unknown chains of transmission, indicating that the outbreak is spreading faster than health officials can trace infections.

Ebola Bundibugyo Outbreak

Ebola is a severe and often fatal viral hemorrhagic fever first identified in 1976. Since then, more than 30 outbreaks have been recorded, primarily in Central and West Africa.

The Ebola outbreak, declared in eastern Congo on May 15, is the fastest-growing Ebola outbreak on record. The outbreak is caused by the Bundibugyo virus, a less common Ebola virus species for which there is no approved vaccine or treatment.

The Bundibugyo virus spreads through direct contact with the blood or bodily fluids of a person infected with, or who has died from, the disease.

It can also spread through contact with contaminated objects such as clothing, bedding, needles, and medical equipment, as well as through infected animals, including bats and non-human primates. Historically, Bundibugyo virus outbreaks have recorded fatality rates ranging from 25% to 50%.

Symptoms To Watch For

Symptoms of Bundibugyo virus disease are similar to other forms of Ebola and include:

• Fever
• Headache
• Muscle pain
• Weakness
• Diarrhea
• Vomiting
• Stomach pain
• Unexplained bleeding or bruising, usually in the later stages of illness.

Unlike many other cancers, cervical cancer is considered highly preventable through a combination of HPV vaccination, regular screening, and timely treatment of precancerous lesions.

India has recorded a significant decline in cervical cancer burden, with new cases falling by 37% over the past decade, according to data from the Indian Council of Medical Research's (ICMR) National Cancer Registry Programme (NCRP).

Experts say widespread screening, awareness, and increasing uptake of the human papillomavirus (HPV) vaccine have contributed to the milestone.

Cervical Cancer Cases Drop In India

The latest estimates show that the number of new cervical cancer cases has dropped from approximately 1.27 lakh annually to around 79,000, marking a major public health milestone in the fight against one of the most common cancers affecting Indian women.

"Cervical cancer is one of the few cancers that can largely be prevented through timely screening and vaccination," Dr. Amitabh Shankar, Head of Preventive Oncology at Dr. B.R. Ambedkar Institute Rotary Cancer Hospital, AIIMS, was quoted as saying.

He attributed the decline to improved awareness, wider availability of screening services, and the gradual expansion of HPV vaccination.

Positive Impact Of Screening And HPV Vaccination

According to experts, early detection through routine cervical cancer screening allows precancerous changes to be identified and treated before they develop into cancer.

At the same time, HPV vaccination protects against high-risk strains of the human papillomavirus, the leading cause of cervical cancer.

The report suggests that increased access to healthcare services, government-led awareness initiatives, and preventive programs have played an important role in reducing the cases of cervical cancer.

Despite the progress, specialists caution that cervical cancer continues to be a major health concern in India, particularly in rural and underserved regions where screening coverage and HPV vaccination remain limited.

They emphasize that expanding HPV vaccination among eligible adolescents, strengthening population-based screening programs, and improving early diagnosis will be essential to prevent it.

About HPV Vaccine

The human papillomavirus causes more than 200 known infections. While some types lead to benign skin warts, others are responsible for severe health threats, such as cervical, throat, anal, and penile cancers.

The HPV vaccine provides strong protection against the most lethal strains, avoiding long-term health complications. It helps the immune system recognize and fight off high-risk strains of the virus before they cause harm. It protects against:

• Genital warts
• Cervical cancer
• Vaginal, vulvar, anal, and penile cancers
• Mouth, throat, head, and neck cancers linked to HPV

What Is Cervical Cancer?

Cervix is located in the pelvic cavity, about 3 to 6 inches inside the vaginal canal. It serves as the entrance to the uterus to the vagina. As per the World Health Organization (WHO), almost all cervial cancer are linked to human papillomaviruses (HPV) which are transmitted through sexual contact

Symptoms Of Cervical Cancer

Cervical cancer has no symptoms in the early days and therefore, is hard to detect until it has spread. Early-stage cervical cancer symptoms include:

• Vaginal bleeding after sex
• Vaginal bleeding post-menopause
• Vaginal bleeding between periods or unusually heavy/long periods
• Watery vaginal discharge with a strong odour or containing blood
• Pelvic pain or pain during intercourse

• Persistent early-stage symptoms
• Painful or difficult bowel movements or rectal bleeding
• Painful or difficult urination or blood in the urine
• Persistent dull backache
• Swelling of the legs
• Pain in the pelvis or lower abdomen

Takeda Biopharmaceuticals India today announced that QDENGA (TAK-003) has become the first dengue vaccine to receive approval in India, marking a major milestone in the country's fight against the mosquito-borne disease.

The Drug Controller General of India (DCGI) has granted market authorization for QDENGA to prevent dengue in individuals aged 4-60 years. According to Takeda, it is India's first approved dengue vaccine and can be administered regardless of previous dengue infection, without requiring pre-vaccination testing.

"Since its launch in 2022, QDENGA has been approved in 43 countries, with more than 32 million doses distributed globally. This approval marks an important step forward in strengthening dengue prevention in India," said Dr. Mahender Nayak, Head of Intercontinental Markets.

QDENGA Vaccine: Why The Approval Matters

The approval comes at a critical time as dengue cases in India have risen sharply over the past two decades.

India accounts for nearly one-third of the global dengue burden. In 2025, more than 113,000 dengue cases were officially reported, although modelling studies suggest the true number of infections may run into tens of millions annually due to underreporting.

Rapid urbanization, climate change and widespread mosquito breeding have made dengue a year-round public health concern. Since there is no specific antiviral treatment for dengue, prevention remains the most effective strategy.

"India carries a substantial dengue burden, and all four dengue virus serotypes co-circulate in several regions. QDENGA is designed to protect against all four serotypes regardless of prior exposure," said Dr. Goh Choo Beng, Medical Affairs Head, Southeast Asia & India Cluster.

QDENGA: Scientific Evidence

The DCGI approval is supported by Takeda's global clinical development programme comprising 19 Phase 1, 2 and 3 clinical trials involving more than 28,000 participants in dengue-endemic and non-endemic regions.

The pivotal Phase III TIDES (DEN-301) study enrolled more than 20,000 participants across eight countries and evaluated the vaccine's long-term safety and effectiveness.

Key findings include:

• 80.2% vaccine efficacy against virologically confirmed dengue one year after the second dose.
• 90.4% efficacy against dengue-related hospitalization at 18 months.
• 84.1% protection against dengue-related hospitalization after 4.5 years.
• Safety and efficacy data demonstrating protection for up to seven years across all four dengue virus serotypes.

The approval is also supported by an Indian Phase III (DEN-302) trial involving participants aged 4-60 years, which found QDENGA to be safe, well-tolerated and immunogenic in children, adolescents and adults.

What Is QDENGA?

QDENGA (TAK-003) is a live-attenuated tetravalent dengue vaccine designed to protect against all four dengue virus serotypes.

It is administered as two 0.5 mL subcutaneous doses, given three months apart.

The vaccine is built on a DENV-2 backbone, incorporating structural proteins from DENV-1, DENV-3 and DENV-4 to provide broad immune protection.

The World Health Organization (WHO) recommends QDENGA for use in dengue-endemic settings without the need for pre-vaccination screening. The vaccine is also included in the WHO List of Prequalified Vaccines, allowing procurement through agencies such as UNICEF and PAHO.

The vaccine has been approved in 43 countries across Asia, Latin America and Europe. It is already part of Brazil's National Immunization Program and is available through public immunization programmes in Argentina, Colombia and Indonesia.

Who can take QDENGA?

The vaccine is approved in India for people aged 4-60 years to help prevent dengue disease.

Manufacturing In India

Takeda had partnered with Indian vaccine manufacturer Biological E in 2024 to expand production of QDENGA.

Under the agreement, Biological E plans to manufacture 50 million doses annually, supporting Takeda's goal of producing 100 million doses globally each year by the end of the decade.
