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

Australia has officially lost its status as the last continent free of the H5N1 bird flu virus after authorities confirmed the highly pathogenic strain on the mainland.

The highly contagious H5N1 variant of avian influenza has now been detected on every continent, marking a significant moment in the disease's global spread.

H5N1 Confirmed In Two Wild Birds

The virus was first detected in a migratory seabird, a brown skua, found on a beach in Cape Le Grand National Park near Esperance in Western Australia, around 700 km southeast of Perth.

Authorities later confirmed a second positive case in a northern giant petrel found on a remote beach along Western Australia's south coast.

Agriculture Minister Julie Collins said testing conducted by the Commonwealth Scientific and Industrial Research Organization (CSIRO) confirmed both birds were infected with H5N1 avian influenza.

"We all knew we couldn't be bird flu-free forever," Collins told a press conference.

No Evidence of Widespread Outbreak Yet

Despite the discovery, officials say there is currently no evidence of mass wildlife deaths or spread into Australia's poultry industry.

Collins said Australian poultry and agricultural systems remain free of bird flu and authorities are investigating whether the virus has become established in local wildlife populations.

"We are working to determine whether the H5 bird flu has established in the wildlife of Australia, other than these two isolated birds," she said.

Samples from the infected birds will undergo further analysis over the coming week as researchers look for signs of transmission to other species.

Further, Western Australia's Chief Veterinary Officer Michelle Rodan said authorities had received 58 reports of sick or dead birds through an emergency hotline between Friday and Sunday afternoon. Nine samples have so far been collected for testing.

Until now, Australia was the only continent where the H5N1 strain had not been detected. Although the virus has circulated across Asia since the 1990s and reached Antarctica in 2024, Australia had remained unaffected.

According to Dr. Michelle Wille, ARC Future Fellow at the University of Melbourne, Australia's unique bird migration patterns likely delayed the virus's arrival.

"There are no duck species which routinely migrate between Australia and Asia, nor are there ducks that migrate through Antarctica," Wille wrote in The Conversation.

However, evidence suggests other seabirds—including gulls, skuas and giant petrels—may have helped carry the virus over long distances across Antarctica and subantarctic regions, eventually bringing it closer to Australia, he said.

Why H5N1 Is A Concern

Read to Know: How Climate Change Is Increasing the Global Disease Burden | Explained

H5N1 is a highly pathogenic strain of avian influenza that can spread rapidly among poultry and wild bird populations, causing severe disease and high mortality rates in birds.

While human infections remain rare, they can occur through direct and unprotected contact with infected birds, animals, or contaminated environments.

Although severe human cases have historically shown a mortality rate of around 50%, sustained human-to-human transmission has not been observed.

How To Protect Yourself

Health authorities recommend the following precautions:

• Avoid direct contact with sick or dead wild birds and other animals whenever possible.
• Observe wildlife from a safe distance.
• Wear appropriate personal protective equipment (PPE) if handling sick or dead birds or animals is unavoidable.
• Avoid touching surfaces contaminated with bird droppings, saliva, mucus, litter, or bedding from infected or suspected animals.
• Do not consume raw milk or raw milk products, particularly from animals suspected or confirmed to be infected with avian influenza.
• Report sick or dead birds to local authorities if encountered.

As several European countries grapple with severe heatwave conditions, the World Health Organization (WHO) has sounded the alarm, warning that rising temperatures are becoming a major public health emergency.

"Heat is no longer only a weather story. It is a health emergency," said Hans Kluge, WHO Regional Director for Europe, in a post on social media.

The warning comes as Europe faces another summer of extreme temperatures, with the global health organization linking the trend to "climate change, rapid urbanization, and an "aging population".

Heat An Urgent Public Health Threat

In its recently launched Heat-Health Action Plans Guidance, the WHO described extreme heat as an "urgent and growing public health threat."

The agency noted that rising temperatures increase illness and deaths, place additional strain on healthcare and social care systems, and disproportionately affect vulnerable groups such as older adults, children, people with chronic illnesses, and outdoor workers.

"Our Region is the fastest-warming region globally. In the past four years alone, heat has claimed more than 200,000 lives, while heat-related mortality has risen by 30% over the past 20 years," said Kluge, in an interview with BBC News.

He stressed that many heat-related deaths can be prevented through timely action and preparedness.

The WHO Europe also urged governments, employers, and institutions to strengthen heat action plans to protect vulnerable populations.

France

Officials have announced a partial alcohol ban in certain areas and strengthened wildfire preparedness measures. The government has also ordered increased monitoring of water supplies used to cool the country's nuclear reactors.

Germany

Spain

In Spain, extreme heat forced the closure of a soccer fan zone, highlighting the impact of rising temperatures on public events and outdoor activities.

Portugal

Portugal is expected to experience its hottest conditions early next week. According to the Portuguese Institute for Sea and Atmosphere (IPMA), temperatures could reach as high as 42°C.

Italy

Italy is also preparing for a significant heatwave. Weather forecasts suggest temperatures in several northern and central cities could hit 40°C for the first time this year, affecting both residents and tourists across the country.

UK

Storm Alert

Alongside soaring temperatures, several European countries are facing the risk of severe storms. Meteorological agencies have warned that heat and humidity could fuel thunderstorms, increasing the likelihood of flash floods, strong winds, and other weather-related disruptions.

WHO Calls For Immediate Action

WHO Europe has urged governments, employers, and institutions to strengthen heat action plans to protect vulnerable populations.

Kluge said that it is important to

• warn communities early,
• make cities cooler,
• ensure access to water and shade,
• check on those most at risk,
• prepare health systems before temperatures peak.

How To Protect Yourself During Extreme Heat

To reduce the health risks associated with extreme temperatures, one should

• Stay hydrated throughout the day
• Seek shade and cooler indoor environments
• Avoid outdoor activities during peak afternoon heat
• Check regularly on elderly relatives, neighbors, and other vulnerable individuals
• Follow public health advice issued by local authorities
• Protecting outdoor workers from midday heat exposure.

The Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda, caused by the Bundibugyo virus, has reached 952 confirmed cases and 247 deaths, according to the latest update from the Africa Centres for Disease Control and Prevention (Africa CDC).

As of June 18, the DRC accounts for 933 confirmed cases and 245 deaths, while Uganda has reported 19 confirmed cases and two deaths. Uganda has not shown the same level of sustained transmission seen in

the DRC.

The overall case fatality rate currently stands at 25.9 per cent.

The outbreak caused by the Bundibugyo virus currently has no approved treatment or vaccine, complicating efforts to contain the disease.

Ituri Province Remains The Epicenter

Ituri Province continues to be the hardest-hit region, accounting for approximately 91 per cent of all confirmed cases. The main hotspots include Bunia, Rwampara and Mongbwalu.

Health officials are also concerned about North Kivu, where the case fatality rate has reached 58.4 per cent, with high mortality reported across several affected health zones.

The outbreak has now spread to 34 health zones in the DRC and one district in Uganda. In the DRC, the most affected provinces are Ituri, North Kivu and South Kivu. In Uganda, cases have been reported mainly in Kampala, including both imported and locally transmitted infections, the CDC said.

Treatment Centers Under Severe Pressure

The CDC said response teams continue to expand surveillance, case management, infection prevention and control measures, laboratory testing, border screening, risk communication and community engagement activities.

A new laboratory in Aru, Ituri Province, has become operational, increasing the total number of Ebola testing sites to six.

Despite ongoing efforts, the response remains under significant strain. Treatment centres are operating beyond capacity, with bed occupancy reaching 102% and 349 patients currently admitted across affected health zones.

The CDC also reported several operational challenges, including delays in patient referrals, shortages of ambulances and vehicles, gaps in personal protective equipment (PPE), and limited access to some affected areas.

Contact Tracing Challenges Persist

Surveillance and contact tracing teams continue to face obstacles, including incomplete addresses, delayed investigations and difficulties accessing certain communities.

More than 7,200 contacts have been identified across the two countries and are being monitored, the CDC said.

Africa CDC also estimates that $21.5 million is urgently needed to address critical gaps in the outbreak response.

Outbreak Outpacing Response Efforts

The outbreak's impact has been particularly severe among vulnerable populations. Last week, another six-month-old girl died from Ebola. She was the third child to die at an orphanage in eastern Congo during the current outbreak.

"It has been a month after the Ebola outbreak and it is still outpacing our response efforts. There are big gaps in surveillance, diagnosis, contact tracing and community engagement," said Dr. Kerry Dierberg of Doctors Without Borders (MSF), which is helping lead medical response efforts in Congo, the Indian Express reported.

Public health experts warned that the outbreak is spreading faster than health authorities can detect and contain it.

Many infected individuals are not reaching hospitals or health centers and may be dying without being identified as Ebola cases. As a result, health workers are struggling to determine the true scale of transmission, increasing the risk of further spread within the region, NPR reported.
