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

Do partners and spouses of those suffering from dementia face a higher risk of the disease themselves? A nationwide study involving more than 955,000 married adults has found that people whose spouse develops dementia may face a significantly higher risk of developing the condition themselves.

The study, published in JAMA Network Open, adds to growing evidence that dementia risk may not be influenced by genetics and lifestyle alone, but also by the shared environments, lifestyles and experiences couples build over decades.

How Was The Study Conducted?

Researchers analyzed health data from 955,105 married individuals in Taiwan to examine whether being married to someone with dementia influences a person's own likelihood of developing the disease.

The researchers found that spouses of people with dementia had a substantially higher risk of developing dementia themselves compared with those whose partners did not have the condition.

Among women, having a spouse with dementia was associated with a 74% higher risk of developing dementia (hazard ratio [HR] 1.74). Among men, the risk was 69% higher (HR 1.69).

The association remained consistent across different forms of dementia, including:

• Alzheimer's disease
• Vascular dementia
• Other types of dementia

The association appeared to be weaker among couples with higher household incomes or more children, suggesting that social and family support may help reduce some of the caregiving burden.

Dementia Is Not Contagious

The findings do not suggest that dementia spreads from one spouse to another. Instead, researchers believe the increased risk is likely driven by several shared factors that accumulate over years of living together. These include:

• Similar dietary habits
• Shared physical activity patterns
• Common environmental exposures
• Cardiovascular risk factors such as diabetes and hypertension
• Psychological stress associated with caregiving
• Reduced social engagement and chronic emotional strain

Because married couples often share many aspects of daily life, they may also share health risks that influence cognitive ageing.

Is Caregiving A Factor?

When one partner develops dementia, the other often becomes the primary caregiver. Caregiving can involve years of emotional stress, disrupted sleep, depression, social isolation and physical exhaustion.

Older research has shown that chronic stress may negatively affect brain health through hormonal, inflammatory and vascular pathways, potentially contributing to cognitive decline.

The authors wrote, "The association was evident on relative and absolute scales and varied by family and socioeconomic context."

They added that future studies should directly measure caregiving intensity, lifestyle factors and other shared pathways to better understand why spouses appear to face an elevated dementia risk.

The findings suggest that healthcare providers should pay attention not only to people diagnosed with dementia but also to their spouses. Experts say spouses may benefit from:

• Regular cognitive screening
• Mental health support
• Caregiver assistance programmes
• Stress management
• Maintaining physical activity and social engagement
• Managing blood pressure, diabetes and other cardiovascular risk factors

Early recognition of cognitive changes may allow interventions that help delay progression and improve quality of life.

Where You Live Matters Too

According to recent studies, various factors could influence your risk of developing dementia. Researchers from the University of Southern California studied health data from more than 214,000 adults across 21 countries.

They found that while many well-known dementia risk factors are universal, their impact can vary significantly depending on a person's country.

Previous research has estimated that nearly 45% of dementia cases could potentially be delayed or prevented by addressing modifiable risk factors, including controlling blood pressure, managing diabetes, staying physically active, treating hearing loss, avoiding smoking, and maintaining social life.

GLP-1 drugs widely used to manage and treat obesity and type 2 diabetes may also help people stay healthier at work. A new study finding that the medications were associated with a 17.3% reduction in absence due to sickness among employed adults.

The study, conducted by researchers from the University of Copenhagen, the University of Chicago, Duke University, and the ROCKWOOL Foundation, analyzed nationwide Danish health and employment records to examine whether GLP-1 treatment affects the conditions of labour market.

Researchers found that people who started GLP-1 therapy experienced significantly fewer episodes of medically certified sick leave lasting longer than 30 days compared with similar patients who began treatment later.

"We find that GLP-1 treatment reduces long-term sickness absence by 17.3% over four years," the researchers wrote in the working paper.

The reduction became more pronounced over time, increasing from around 0.8 percentage points in the first two years after treatment began to 1.1 percentage points during years three and four.

Benefits Of GLP-1 Drugs Beyond Weight Loss

GLP-1 receptor agonists, including Ozempic and Wegovy, have become best known for helping people lose weight. However, researchers say their benefits may extend well beyond weight loss. The study also found that patients receiving GLP-1 therapy had:

• Fewer emergency department visits.
• Lower use of cardiovascular medications.
• Reduced reliance on long-term sickness benefits.

Together, these statistics translated into estimated annual savings equivalent to 1.3% to 1.5% of an employed person's yearly income through fewer prolonged absences from work.

"Our findings suggest meaningful fiscal spillovers from GLP-1 treatment through reduced sickness absence," the authors said.

However, the researchers found no significant evidence that the medications increased overall employment, labor-force participation, or earnings during the four-year follow-up period.

The researchers believe the medications likely improve people's overall health enough to reduce serious illnesses that keep them away from work.

GLP-1 drugs work by mimicking a hormone called glucagon-like peptide-1, which helps regulate appetite, blood sugar and digestion. They are known to:

• Improve blood sugar control.
• Promote substantial weight loss.
• Lower the risk of cardiovascular complications.
• Reduce obesity-related health problems.

These health improvements may translate into fewer hospital visits and fewer prolonged medical absences.

Researchers Warn

The researchers cautioned that the findings should not be interpreted as evidence that GLP-1 drugs automatically improve workplace productivity.

The study was based on Danish national data, where healthcare access and paid sick-leave policies differ from those in countries such as the United States and India.

In addition, the study focused on patients prescribed GLP-1 medications for medical reasons, including obesity and type 2 diabetes, rather than people using the drugs primarily for cosmetic weight loss.

The findings add to a growing body of evidence suggesting GLP-1 drugs may offer benefits beyond managing diabetes and obesity. Previous research has linked these medications to lower risks of heart disease, kidney disease, obstructive sleep apnea, and certain liver conditions.

If confirmed across different countries, the latest findings suggest that the drugs could also provide broader economic benefits by reducing long-term sickness absence and easing the burden on healthcare systems.

Millions of Americans rely on cetirizine, the generic version of Zyrtec, to keep seasonal allergies at bay. But a recent nationwide recall has raised concerns after some tablets were found to be contaminated with another medication, prompting FDA to warn consumers to check their medicine bottles.

The US Food and Drug Administration (FDA) has announced that India-based company Unique Pharmaceutical Laboratories, a division of J.B. Chemicals & Pharmaceuticals Ltd., is voluntarily recalling four lots of Cetirizine Hydrochloride Tablets USP 5 mg because of potential cross-contamination with ranitidine, a medication used to treat heartburn and stomach ulcers.

Why Was The Allergy Medicine Recalled?

According to the FDA, the recall was initiated after a pharmacy technician noticed unusual tablets. Some cetirizine tablets had red dots or discoloration, which led to a proper investigation. The company later confirmed that certain tablets had been cross-contaminated with ranitidine during manufacturing.

The FDA, in its recall announcement, said, "Unique Pharmaceutical Laboratories is voluntarily recalling four lots of Cetirizine Hydrochloride Tablets USP 5 mg to the consumer level due to cross contamination with Ranitidine."

Although no adverse events have been reported so far, the company is recalling the medication as a precaution because taking an unintended drug could pose health risks for certain patients.

Why Is Cross-Contamination A Grave Concern?

Cross-contamination occurs when traces of one medication accidentally end up in another drug during manufacturing or packaging.

In this case, people expecting to take an allergy medicine could unknowingly consume ranitidine which could lead to adverse effects.

While ranitidine was once commonly used to treat acid reflux and heartburn. The medication decreases the amount of acid made in the stomach, according to MedlinePlus and the U.S. National Library of Medicine.

The accidental exposure is particularly concerning for people who are hypersensitive to ranitidine or its ingredients.

According to the FDA, these individuals could experience reactions ranging from mild allergic symptoms to potentially life-threatening conditions.

Although Unique Pharmaceutical Laboratories said it has not received any reports of adverse reactions related to the recalled tablets, the contamination could pose a serious risk for people who are allergic or hypersensitive to ranitidine.

According to the recall notice, individuals who unknowingly take the contaminated tablets could experience anaphylaxis, a severe and potentially life-threatening allergic reaction that requires immediate medical attention. Symptoms of anaphylaxis may include:

• Difficulty swallowing
• Loss of consciousness
• Hypotension (low blood pressure)
• Dyspnea (shortness of breath)
• Angioedema (sudden swelling beneath the skin)
• Swelling of the throat or face
• Pruritus (itching)
• Urticaria (hives)

What Should You Do If You Have The Recalled Medication?

Consumers who have the affected cetirizine tablets should stop using the product and check whether their bottle belongs to one of the recalled lots. Anyone who develops symptoms like swelling of the face or throat, difficulty breathing or swallowing, hives, or dizziness after taking the medication should seek immediate medical attention.
