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

The Democratic Republic of the Congo is actively expanding Ebola treatment capacity as the country battles its worst and fastest-growing Ebola outbreak. But a growing shortage of health workers is threatening the ability to run the new treatment centres and contain and manage transmission and infections.

According to the latest figures by Congolese authorities on September 23, the outbreak has across into seven provinces, with 7,773 confirmed cases and 3,759 deaths. The WHO says transmission remains out of control, even though cases are going down in some areas.

The situation is particularly grim in North Kivu, where cases increased by 73% over three weeks. At the same time, cases fell by 26% in Ituri and 15% in Haut-Uele between August 31 and September 20, highlighting how differently the outbreak is behaving across provinces.

More Treatment Centres May Not Be Enough

The country has rapidly increased its capacity to treat patients. By September 1, affected provinces had 59 facilities with 1,346 beds, compared with just one nine-bed treatment centre when the response began in May. More than 4,000 additional health workers had also been deployed.

But beds and buildings can only help if there are enough people to staff them. According to WHO officials, an Ebola treatment centre can require around 300 healthcare professionals, including doctors, nurses, anaesthetists and hygiene staff. Some newly established centres therefore do not have enough personnel to operate at full capacity.

This creates a difficult situation of treatment infrastructure being expanded, but the workforce needed to run it is not keeping pace.

Ebola Pressure On Health Workers

Ebola treatment is particularly laborious as healthcare workers must provide intensive care while following strict infection-prevention measures.

Patients may require monitoring for dehydration, bleeding and other complications, while staff must work in protective equipment and follow procedures designed to prevent transmission.

The response has also been impacted by insecurity, population displacement, movement between communities and a strike by some health workers over unpaid wages. These factors can make it harder to maintain staffing.

Early treatment is key as many patients are still reaching healthcare facilities late. WHO previously reported that around 60% of weekly Ebola deaths were occurring in communities rather than treatment centres, pointing to delays in detection and access to care.

Early Treatment Is Important

Ebola can cause fever, weakness, vomiting, diarrhoea and, in severe cases, bleeding and organ failure. The longer a severely ill patient remains without appropriate supportive care, the harder the disease can be to manage. Treatment centres help isolate infectious patients helps break transmission chains.

Children are another major concern in the current outbreak. Nearly one in four confirmed cases are children, but they account for almost one in three deaths. Children under five have been particularly vulnerable as more than 60% of confirmed cases in this age group resulting in death, compared to fewer than 30% among adults, according to WHO.

Developments In Vaccine & Treatment So Far

The outbreak has been identified as being caused by Bundibugyo virus, one of the viruses in the Ebola family. WHO reported a case fatality ratio of 48.3% among confirmed cases in the DRC as of September 7.

There is currently no approved vaccine or specific treatment for Bundibugyo ebolavirus, which means, health officials are completely relying on breaking transmission chain and providing prompt medical care to control the spread.

But the latest unfortunate developments point to a problem that could make containment even more challenging. The response desperately needs enough trained people, supplies and access to affected communities.

As there is currently no vaccine for Bundibugyo virus, health authorities have approved 70,000 doses of Ervebo, vaccine meant for a much familiar Zaire strain of Ebola. Health workers in DRC have begun receiving the Ervebo doses as part of an experimental trial to test if it would work on current Ebola outbreak.

With speed, sudden drops and dizzying twists at hundreds of feet in the air, roller coasters are meant to give riders an adrenaline rush and thrill. But a recent incident related to brain bleeding has shed light on the harmful impact of these extreme movements inside the brain.

A recent investigation found discovered that serious brain injuries have been allegedly linked to the X2 roller coaster at Six Flags Magic Mountain in California.

According to CNN, more than 100 people have allegedly suffered brain injuries after riding the attraction over the past two years. Three lawsuits were filed this week against Six Flags.

Two women who rode X2 just six days apart in July suffered severe brain haemorrhages and required emergency surgery. Doctors treating them attributed their injuries to rapid acceleration and deceleration experienced during the ride.

The cases raise the medical question of what happens to the brain when the body is subjected to sudden, powerful changes in speed and direction?

Can Roller Coasters Cause Brain Bleeds?

The brain is surrounded by cerebrospinal fluid, which cushions it against everyday movements and minor impacts. However, this protection has its own limits.

When a roller coaster suddenly accelerates, brakes or changes direction, the head and brain may not always necessarily move at exactly the same speed.

The brain can shift, stretch or rotate within the skull, placing strain on delicate blood vessels and nerve fibres. In extreme circumstances, these forces can tear blood vessels and cause bleeding inside the skull.

So it's not necessary that a person needs to hit their head against a hard surface to sustain a traumatic brain injury. Rapid rotational movements alone can sometimes cause significant damage to the brain.

What Is A Subdural Haematoma?

A subdural haematoma is a life threatening brain injury, in which the blood collects between the brain's outer protective covering, called the dura mater, and the brain's surface.

Sudden acceleration and deceleration can tear the veins that connect the brain to its surrounding structures.

As blood accumulates, pressure inside the skull increases. This can compress brain tissue and, in severe cases, require emergency surgery to remove the blood and relieve pressure.

G-Forces Are Another Factor

G-force means the acceleration experienced by the body relative to Earth's gravity. During sharp turns, steep drops and sudden brakes, roller coaster riders experience changing G-forces. However, G-force alone does not determine whether someone will sustain a brain injury.

The speed and direction of head movements, specially rapid rotation, may also contribute to brain bleeds. A small 2017 study found that roller coasters could produce brain movement and strain comparable to mild football headers. However, the researchers did not find evidence of an immediate risk of acute brain injury on the rides studied.

Warning Signs After Riding A Roller Coaster

Serious neurological injuries associated with roller coasters are considered to be rare. The Six Flags cases do not establish that an ordinary roller coaster rides will have the same risks as X2.

People with existing vascular abnormalities, previous head injuries or those taking blood-thinning medications may face additional risks.

A headache after a roller coaster ride may seem harmless, but certain symptoms require immediate medical attention.

According to the US Centers for Disease Control and Prevention, warning signs of a traumatic brain injury include worsening headaches, repeated vomiting, confusion, slurred speech, seizures, weakness and loss of consciousness. Symptoms can appear immediately or develop hours later.

A popular organic applesauce has been recalled in the US after routine testing by the US Food and Drug Administration (FDA) revealed high levels of patulin, a toxin produced by certain molds that can grow on apples.

Wakefern Food Corp. voluntarily recalled select containers of Wholesome Pantry Organic Unsweetened Apple Sauce after the patulin levels were found to exceed food safety limits. No illnesses linked to the toxin have been reported yet.

The recall involves 23-ounce plastic jars with UPC 04119005677 and a best-by date of June 16, 2027. The product was sold through ShopRite, Price Rite Marketplace, The Fresh Grocer, Gourmet Garage and Fairway Market.

What Is Patulin?

Patulin is a mycotoxin, meaning it is a toxic chemical produced by certain species of fungi or mold.

The FDA identifies molds from genera including Penicillium, Aspergillus and Byssochylamys as sources of patulin. Apples are one of the best-known sources, particularly when fruit is bruised, damaged, rotten or improperly stored.

When contaminated apples are used to make products like apple juice or applesauce, the toxin can remain it. The pasteurisation does not eliminate patulin, so simply heating an apple product is not a reliable way to get rid of the toxin.

How Dangerous Is Patulin?

The health concern depends on the amount and duration of exposure to patulin. According to the FDA, consuming food or beverages containing high levels of patulin may cause nausea and vomiting, while evidence also indicates that the toxin can damage cells. The agency monitors patulin because prolonged exposure to elevated levels may pose a serious health hazard.

The FDA has established an action level of 50 parts per billion (ppb) for patulin in apple juice, apple juice concentrates and apple juice products.

This does not mean that eating a food once above the regulatory limit automatically causes poisoning. Food safety limits are designed to control exposure and reduce potential health risks, particularly when contamination could occur repeatedly.

Patulin In Applesauce

Molds formed due to patulin can grow on apples that have been bruised, damaged or allowed to rot. Contamination can also happen during storage.

The problem can be difficult to identify simply by looking at the finished food. FDA guidance notes that some contamination can originate from internal problems like core rot that may not be obvious from the outside of an apple. Removing damaged fruit before processing is therefore an important control measure.

So, anyone who has the recalled Wholesome Pantry Organic Unsweetened Apple Sauce at home should not consume it.

Consumers should check the jar for the 23-ounce size, UPC 04119005677 and best-by date June 16, 2027. The company says recalled products can be returned to the store for a refund or replacement.
