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.
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.
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.
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.

For 57-year-old Brenda Young, her mother’s death last year caused an ‘intense, overwhelming pain in the middle of the chest’, so severe that she required hospital admission.
While her symptoms felt like a heart attack, the Scottish woman was diagnosed with ‘broken heart syndrome’.
Also called takotsubo cardiomyopathy, it is a sudden condition estimated to affect at least 5000 people in the UK each year.
Now she is part of a groundbreaking trial by a team of scientists in the UK to gauge a medication for the long-term management of the condition.
As the name suggests, the fatal condition is triggered by sudden emotional stress, such as the loss of a loved one. While it is often mistaken for a heart attack, it mimics a heart attack, causing sudden chest pain, breathlessness, and weakened heart muscles.
However, unlike heart attacks, it is not caused by a blockage in the heart arteries but instead, a severe weakening of the heart muscle.
There is currently no proven treatment for takotsubo, which means treatments can vary from person to person. We know that following an attack, the impact on the patient’s quality of life can be extremely debilitating.

The seven-year-long study, funded by the National Institute for Health and Care Research (NIHR), will involve scientists and clinicians from Aberdeen, Glasgow, Edinburgh, Leeds, Leicester, Belfast, and almost 1,000 takotsubo patients from 40 hospitals across the country.
“Takotsubo syndrome affects thousands of people in the UK year on year – most of whom are women. The figures are stark in that one in ten will ultimately die from their condition. It is a growing problem, and with ever-improving clinical recognition, the diagnosis rate has increased 5-fold in the past decade,” said Dana Dawson, Chair in Cardiovascular Medicine at the University of Aberdeen, who is leading the trial.
The long-term risk of death or serious health problems after a takotsubo attack is similar to that of patients who have had a heart attack. In those who survive the first attack, patients live with a higher risk of death, heart attacks, strokes, and heart failure, as well as a higher risk of repeated takotsubo attacks.
It has been suggested that a class of medicines that relax blood vessels, called 'renin-angiotensin system (RAS) inhibitors', could be an effective course of treatment in the longer term for takotsubo patients.
Currently used to treat heart attacks due to heart artery blockage, high blood pressure, or heart failure, this study will scientifically test the effectiveness of RAS inhibitors in takotsubo to establish if this could be a treatment pathway specific to the condition.
“We will test, for the first time, if RAS inhibitors could prevent deaths, heart attacks, strokes, heart failure, and repeated takotsubo attacks in people who have suffered an acute takotsubo attack,” Professor Dana said.
“We hope that this will make it clear whether or not these drugs are effective at preventing repeated health problems in the long-term,” the expert said.
With the trial, the researchers aim to find the first therapy that improves survival and reduces the burden of disease after a takotsubo attack, or it may help redirect the search to other treatments that may work.

Childhood myopia is emerging as a major public health concern in India, and is beyond the need for spectacles, said health experts from All India Institute of Medical Sciences, New Delhi.
Myopia or nearsightedness is a common vision condition where close-up objects appear clear, but distant objects look blurry.
Recent estimates suggest that by 2050, nearly half of the global population may be affected by myopia. In India, prevalence rates among school-going children have risen sharply over the years, with urban studies indicating nearly 14 per cent prevalence, while rural regions have witnessed a rise from 4.6 per cent to 6.8 per cent over the past decade.
“Childhood myopia is no longer just about children needing spectacles earlier in life; it is increasingly becoming a serious long-term eye health concern," said Dr Jeewan Singh Titiyal, President of All India Institute of Medical Sciences Rajkot (AIIMS Rajkot).
High myopia can:
“Combating childhood myopia requires a collective effort involving families, schools, healthcare systems, and policymakers. School environments must encourage outdoor exposure and healthier visual habits, while parents need to monitor screen dependency and ensure balanced lifestyles,” said Dr Rohit Saxena, Senior Pediatric Ophthalmologist, RP Singh AIIMS, New Delhi.

In response to the alarming rise in childhood myopia across India and globally, the All India Ophthalmological Society (AIOS) has released a comprehensive Consensus Guideline on “Prevention and Management of Childhood Myopia” as part of World Myopia Week 2026, held from May 18 to 24.
Dr Rohit, who is also the Program Director – Myopia Guideline, urged ensuring that adequate sleep, nutrition, and physical activity are not compromised.
“Early diagnosis and timely management can significantly improve outcomes and help protect children from avoidable visual impairment and future sight-threatening complications,” he said.
Dr Jeewan, also the President of AIOS, added that, unfortunately, many children fail to report blurred vision because they do not realize what normal sight should feel like.
The experts attribute the surge in childhood myopia to lifestyle changes accelerated over recent years, including prolonged screen exposure, increasing academic pressure, reduced outdoor activity, and extended periods of near work.
The transition toward digital learning environments has further contributed to children spending 4–6 hours or more daily on screens, often with inadequate visual hygiene practices.

The new recommendations reinforce the importance of the widely advocated 20-20-20 rule, encouraging children to take a 20-second break every 20 minutes and focus on an object 20 feet away to reduce eye strain.
The newly released AIOS guidelines also strongly emphasize preventive strategies, including:
“The prevention and management of childhood myopia require a shift from reactive treatment to proactive prevention. Environmental factors such as prolonged near work, excessive digital exposure, and reduced outdoor time are modifiable risks that demand immediate societal attention," said Dr Namrata Sharma, Professor of Ophthalmology, All India Institute of Medical Sciences, Delhi.
The guidelines also provide insights into currently available myopia control interventions, including:

Amid the scare of hantavirus led by a rare strain that causes human-to-human transmission, the UK government has received supplies of the antiviral drug Favipiravir from Japan to tackle the risk of the rat-borne disease in the country.
The antiviral favipiravir, from the Japanese company Fujifilm, that gained fame during the COVID-19 pandemic, is being considered as an experimental option to treat the deadly hantavirus outbreak linked to the MV Hondius cruise liner. To date, the medication has been tested as an emergency treatment for new or re-emerging flu.
The UK Health Security Agency said that “the supplies of favipiravir would bolster treatment stocks, even though the risk of wider transmission in the UK remained very low”.
The hantavirus outbreak that began on MV Hondius has so far caused three deaths and 11 cases.
There is no specific therapy for hantavirus, which is primarily spread by rodents but can be transmitted between people in rare cases and after prolonged, close contact. Treatment usually focuses on supportive care such as rest and fluids, while some patients may need breathing support.
In Japan, favipiravir is sold under the brand name Avigan by a unit of Fujifilm as an emergency medication for novel or re-emerging flu.
The drug works by blocking a key enzyme that many viruses need to multiply.
Use of favipiravir in hantavirus would generally be considered experimental or compassionate rather than standard care, and most likely to treat severe infection early on, said Piet Maes, a virologist at the University of Brussels, Reuters News Agency reported.
Maes said evidence so far comes only from lab and animal studies, with no strong human trial data showing the drug works against hantavirus. There is no internationally established clinical protocol recommending its routine use for hantavirus.
Favipiravir is a broad-spectrum antiviral medication, most notably produced and marketed in India by Glenmark Pharmaceuticals under the brand name FabiFlu.
First approved in Japan for severe influenza, it became widely recognized for emergency use in the treatment of mild-to-moderate COVID-19 to help rapidly reduce viral load.
Favipiravir has remained controversial due to several side effects reported during the COVID-19 pandemic.
In 2023, in a rare complication from treatment with the COVID-19 antiviral, the eyes of a six-month-old baby boy from Thailand turned an unusual shade of blue.
According to researchers from Chulabhorn Royal Academy in Bangkok, the boy, who suffered fever and cough lasting one day, was diagnosed with COVID infection.
In a prior investigation, a higher frequency of uric acid elevation in younger patients treated with favipiravir was observed, which could be linked to decreased urine output.
In addition, favipiravir has also been shown to cause fluorescence in human hair and nails. This adverse effect may be due to the drug, its metabolites, or additional tablet components such as titanium dioxide and yellow ferric oxide.
