On Thursday, Uganda confirmed an outbreak of the Ebola virus in its capital city Kampala, with the first confirmed patient dying from it a day before. As per the new developments, the officials are now preparing to deploy a trial vaccine to put an end to this outbreak.

Groups of scientists are working on the vaccine and deployment of more than 2,000 doses of a candidate vaccine against the Sudan strain of Ebola has been planned and confirmed by the Uganda Virus Research Institute. As per the World Health Organization (WHO), Uganda has access to 2,169 doses of trial vaccine. For now, however, there are no approved vaccines for the strain and officials are still investigating the source of the outbreak.

The WHO had also allocated $1 million from its contingency fund for emergencies to support quick action and contain the outbreak in the country.

Confirmed Case

On Wednesday, the Sudan strain of Ebola killed a nurse employed at Kampala's main referral hospital. It is after his death that Ebola was declared an outbreak in the country. Post-mortem samples too have confirmed the Sudan Ebola Virus Disease and at least 44 contacts of the deceased man have been listed for tracing. 30 of these are health workers.

Ebola is a highly infectious hemorrhagic fever, which is transmitted through contact with bodily fluids and tissue. Symptoms include headache, vomiting of blood, muscle pains and bleeding.

it was in the late 2022, when Uganda had last suffered an Ebola outbreak. It killed 55 of the 143 people who were infected and was declared over on January 11, 2023.

What Is Ebola Virus Disease?

As per the WHO, Ebola virus disease (EVD) is a rare but severe illness in humans and is often fatal. People can get infected with the virus if they touch an infected animal when preparing food, or touch body fluids of an infected person such as saliva, urine, faeces or semen, or things that have body fluids of an infected person like clothes or sheets.

How Does Transmission Work?

Ebola enters the body through cuts in the skin or when one is touching their eyes, nose or mouth. Early symptoms include fever, fatigue and headache.

It was first discovered in 1976 in two simultaneous outbreak, when in Nzara, South Sudan and other in Yambuku, Democratic Republic of Congo. The latter occurred near a village near the Ebola River, which is where it gets its name from.

It is highly infectious and transmissible disease, in fact, there have been cases of health-care workers who have frequently been infected while treating patients with suspected or confirmed Ebola. This occurs through close contact with patients when infection control precautions are not practiced strictly.

Cases of people conducted burial ceremonies, involving direct contact with the body of the deceased too can lead to the transmission of Ebola. Even after the long suffering and recovery, there is a possibility of sexual transmission. Pregnant women who get acute Ebola and recover may still carry the virus in their breastmilk, or in pregnancy related fluids and tissues.

Symptoms:

• feeling tired
• headache
• muscle and joint pain
• eye pain and vision problems
• weight gain
• belly pain and loss of appetite
• hair loss and skin problems
• trouble sleeping
• memory loss
• hearing loss
• depression and anxiety

A total of 52,10,302 girls across India have received the Human Papillomavirus (HPV) vaccine under the nationwide campaign launched by Prime Minister Narendra Modi in February, the government informed Parliament during the ongoing Monsoon Session.

The nationwide vaccination campaign for 14-year-old girls was launched from Rajasthan's Ajmer as part of India's efforts to eliminate cervical cancer.

“The nationwide HPV vaccination campaign was launched on February 28, for approximately 1.2 crore eligible beneficiary girls aged 14 years across all 36 States and Union Territories. As of July 15, a total of 52,10,302 girls have received the HPV vaccine across the country,” Union Minister of State for Health and Family Welfare Anupriya Patel said in a written reply in the Rajya Sabha.

The Minister said the HPV vaccine is being provided free of cost at designated government health facilities, including:

• Ayushman Arogya Mandirs–Primary Health Centers (PHCs)

• Community Health Centers (CHCs)

• Sub-District Hospitals (SDHs) and District Hospitals (DHs)

• Government Medical Colleges (GMCs)

She also said the government's cervical cancer prevention strategy includes HPV vaccination, screening, early diagnosis at Ayushman Arogya Mandirs (AAMs), and treatment through Day Care Cancer Centers (DCCCs).

Immunization Coverage Remains Above 90%

The Minister also updated Parliament on India's immunization program.

“As per the National Health Policy 2017 goals, the National Full Immunization Coverage has been maintained more than 90% for the last four years,” Patel said. National full immunization coverage was:

• 94.7% in 2022–23

• 93.7% in 2023–24

• 98.3% in 2024–25

• 97.9% in 2025–26

Patel also said that the government has taken several steps to improve preparedness for future pandemics and public health emergencies, including:

• Launch of the Pradhan Mantri-Ayushman Bharat Health Infrastructure Mission (PM-ABHIM) to strengthen public health infrastructure, disease surveillance, diagnostics, research, and emergency response.

• Strengthening the Integrated Disease Surveillance Program (IDSP) with trained multidisciplinary Rapid Response Teams (RRTs).

• Expansion of the Indian Council of Medical Research's Virus Research and Diagnostic Laboratory (VRDL) network to more than 160 laboratories for pathogen diagnosis.

Meanwhile, the Nationwide Viral Research and Diagnostic Laboratories (VRDL) network under ICMR has been expanded to 163 laboratories, comprising 11 Regional VRDLs, 27 State VRDLs and 125 Medical College VRDLs, to strengthen diagnostic capacity across the country.

Cervical Cancer Cases Decline

Meanwhile, recent data from the ICMR's National Cancer Registry Program (NCRP) show that India has recorded a significant decline in its cervical cancer burden.

According to the latest estimates, new cervical cancer cases have fallen by 37% over the past decade, declining from about 1.27 lakh cases annually to around 79,000, marking a major public health milestone in the fight against one of the country's most common cancers among women.

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

The WHO global targets for 2030 include vaccinating 90 percent of girls by age 15, screening 70 percent of women by ages 35 and 45, and ensuring 90 percent of women with pre-cancer and invasive cancer receive appropriate treatment.

Researchers at the Indian Institute of Technology (IIT) Kanpur have uncovered how an experimental vaccine booster molecule activates the body's immune system, a breakthrough that could help researchers develop safer and more effective vaccines in the future.

The study, published this month in the Proceedings of the National Academy of Sciences (PNAS), provides the first detailed structural view of how a synthetic molecule called EP67 binds to and activates an important immune receptor known as C5aR1. The findings offer researchers a molecular blueprint for improving vaccine adjuvants, the ingredients added to vaccines to strengthen and prolong immune protection.

Unlike vaccines, which train the immune system to recognize a specific pathogen, adjuvants help amplify the body's immune response, making vaccines more effective.

Inspired By The Body's Natural Immune System

The researchers developed EP67 by taking inspiration from C5a, a naturally occurring immune protein released during bacterial and viral infections. While C5a helps activate immune cells to fight infections, prolonged activation can trigger harmful inflammation and damage healthy tissues.

To overcome this challenge, the IIT Kanpur team engineered EP67, a much smaller version consisting of just 10 amino acids.

The molecule retains the beneficial immune-stimulating properties of C5a while limiting the inflammatory effects. According to the researchers, EP67 selectively activates dendritic cells and macrophages, two immune cells that play a central role in generating long-lasting immunity, while largely avoiding activation of neutrophils, immune cells that are often responsible for excessive inflammatory responses.

This selective activation makes EP67 a promising candidate as a vaccine adjuvant capable of producing stronger immune protection without triggering inflammation.

Earlier Studies

Previous animal studies have shown the potential of EP67 in boosting vaccine responses.

When incorporated into experimental vaccines against multiple viruses, including SARS-CoV-2, the virus responsible for COVID-19, mice developed stronger immune responses than those receiving vaccines alone. Researchers also observed faster recovery in infected animals.

Beyond vaccines, EP67 has also shown promise against bacterial infections, including methicillin-resistant Staphylococcus aureus (MRSA), a major antibiotic-resistant pathogen.

However, the molecule has not yet entered clinical use in humans, and additional preclinical research will be required before human trials can begin.

Although scientists had previously observed EP67's immune-boosting effects, precisely how the molecule worked remained vague for a long time.

The IIT Kanpur researchers found that EP67 binds to C5aR1, a receptor located on the surface of immune cells. C5aR1 belongs to the large family of G protein-coupled receptors (GPCRs), which are involved in transmitting signals into cells and are among the most common targets for modern medicines.

Using cryo-electron microscopy (cryo-EM), the team captured near-atomic-resolution images showing EP67 adopting a hook-like shape that fits into the centre of the receptor, switching it on and initiating immune activation.

The structural insights have already enabled researchers to redesign EP67 by modifying its amino acid sequence to improve its stability and receptor binding. The next steps would be refining the formulation and introducing it in pre-clinical tests.

People living with Type 2 diabetes may be significantly more vulnerable to severe, potentially life-threatening complications from dengue, according to a new review by diabetes specialists.

The paper, presented in July 2026 and slated for publication in the International Journal of Diabetes & Technology (IJDT), also recommends combining dengue vaccination into routine diabetes care in dengue-endemic regions to better protect patients who are at high risk.

The review comes as many countries, including India, continue to witness surges in dengue cases during the monsoon months.

Can Type 2 Diabetes Make Dengue More Severe?

According to the researchers, chronic high blood sugar weakens the immune system and damages blood vessels, making it harder for the body to fight dengue infection.

It increases the risk of vascular leakage, severe bleeding, organ damage, and other complications associated with severe dengue.

The review notes that diabetes contributes to chronic inflammation, endothelial dysfunction, and impaired immune responses, all of which may worsen the course of dengue infection.

The researchers argue that dengue prevention should become part of routine diabetes management in countries where dengue is endemic. Lead author Dr. Jothydev Kesavadev, diabetologist, said, "People with Type 2 diabetes represent a particularly vulnerable group during dengue outbreaks.

Preventive strategies, including vaccination where appropriate, should become an integral part of diabetes care to reduce severe illness and deaths."

The review was co-authored by several diabetes specialists from across India, including Dr. Niti Pall, President-Elect of the International Diabetes Federation Europe.

It was presented during the 14th Jothydev's Professional Education Forum Annual Global Diabetes Convention in Kovalam, Kerala, and its publication was formally released by Kerala Health Minister K. Muraleedharan.

While the current paper is a review rather than a new clinical trial, it is supported by a growing body of evidence. A 2024 review published in Health Science Reports found that diabetes is significantly associated with severe dengue, death, elevated liver enzymes, and thrombocytopenia.

Similarly, a 2025 review in the International Health journal concluded that accumulating evidence increasingly supports diabetes as an important comorbidity contributing to poor dengue outcomes.

Should People With Diabetes Receive The Recently Approved Dengue Vaccine?

The findings come as India recently approved its first dengue vaccine, QDENGA (TAK-003). The vaccination should follow national guidelines and individual medical advice. Experts emphasize that vaccination complements, rather than replaces, mosquito bite prevention measures.

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.

Precautions

Experts recommend that people with diabetes:

• Maintain good blood sugar control.
• Avoid mosquito bites by using repellents, long-sleeved clothing, and eliminating stagnant water around homes.
• Seek medical attention immediately if dengue symptoms such as high fever, severe headache, vomiting, abdominal pain, bleeding, or rash develop.
• Discuss dengue vaccination with their healthcare provider if they live in an endemic region and are eligible under national recommendations.
