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.

Paul Alexander woke up inside a 600-pound giant metal tube and never left until he died. Paul depended on an iron lung for every breath, a machine that had largely disappeared from modern medicine.
Known as "the man in the iron lung," Alexander spent more than seven decades living inside the metal cylinder after contracting polio as a child. Paul became a symbol of resilience, determination, and the life-saving power of vaccines. His remarkable story is recalled even after his death in March 2024 at the age of 78.
The doctors placed him inside an iron lung, a mechanical ventilator that kept him alive by helping his lungs expand and contract.
Although everyone initially believed he might not survive, Alexander defied expectations. He went on to graduate from college, earn a law degree, become a practicing attorney, publish a memoir, and inspire millions through interviews and social media.
Paul Alexander refused to let the machine define him. Doctors taught him a technique called "frog breathing" or glossopharyngeal breathing. By using the muscles of his mouth and throat, he learned to gulp air into his lungs in small amounts.
This helped him to leave the iron lung for short durations, attend school, pursue higher education, and eventually work as a lawyer. Still, he depended on the iron lung for most of his life, especially while sleeping.
Despite his conditions, Alexander earned a bachelor's degree, graduated from law school, practiced as a lawyer in Texas, and wrote his memoir - Three Minutes for a Dog: My Life in an Iron Lung.
His determination challenged and defied assumptions about disability and demonstrated that severe physical limitations need not prevent education, work, or meaningful relationships.

An iron lung, also called a negative-pressure ventilator, is a large cylindrical machine that helps people breathe when the muscles controlling respiration become paralyzed.
Unlike today's ventilators, which push air directly into the lungs through a tube or mask using positive pressure, an iron lung works by changing air pressure around the patient's body. The patient lies inside an airtight metal chamber with only the head remaining outside.
The machine then repeatedly lowers the air pressure inside the chamber. This causes the chest to expand naturally, drawing air into the lungs. The pressure then returns to normal. The chest relaxes, allowing air to flow back out. This cycle mimics normal breathing and can continue around the clock.
Iron lungs became obsolete eventually after polio vaccines and modern ventilators were developed.
The introduction of effective polio vaccines in the 1950s and 1960s dramatically reduced cases of paralytic polio worldwide.
The positive-pressure ventilators we use today are smaller, more portable, and better suited to intensive care. They deliver oxygen directly into the lungs, replacing bulky iron lungs.
Paul Alexander's life is more than a remarkable survival story. It serves as a reminder of the devastating impact infectious diseases once had before vaccines transformed public health.

Amid earthquake rescue efforts, Venezuela has reported an outbreak of rat-borne hantavirus that has claimed three lives so far, according to the country's health ministry.
Three people with confirmed hantavirus infection died in the eastern state of Anzoátegui. Two other deaths—both involving health professionals in the state of Barinas—are still under investigation and are not linked to the Anzoátegui cases, the ministry said.
"We report the regrettable deaths of three patients in Anzoátegui with confirmed diagnoses of hantavirus," the ministry said in a statement.
The ministry added that there is "no scientific evidence of person-to-person transmission in our country," noting that the virus is primarily spread by rodents in rural and agricultural areas.
The fresh cases are reported barely two weeks after the World Health Organization (WHO) declared the end of the hantavirus outbreak linked to the MV Hondius luxury expedition ship, which infected 11 people and claimed three lives earlier this year.
According to the WHO, hantaviruses are zoonotic viruses that naturally infect rodents and are occasionally transmitted to humans. In humans, the infection can cause severe illness and may be fatal, although symptoms vary depending on the virus strain and geographic region.
The virus is primarily transmitted through contact with infected rodents or their urine, droppings, saliva, and, less commonly, through scratches or bites.
According to the CDC, symptoms can appear one to eight weeks after exposure, initially presenting fatigue, fever, and muscle aches. As the disease progresses, it can cause coughing, shortness of breath, and chest tightness as fluid accumulates in the lungs.

Researchers from the US National Institutes of Health's (NIH) National Institute of Neurological Disorders and Stroke reviewed data from 811 patients infected with the Puumala strain of HFRS.
They found that 97% experienced headaches, 40% reported blurred vision, and 31% experienced vomiting. About 1% developed severe complications such as meningitis or encephalitis, while rare cases involved peripheral neuropathy or stroke.
Pituitary damage was identified as a significant complication of HFRS. It can lead to hormonal disorders weeks or even months after infection. These may include fatigue, adrenal insufficiency, diabetes insipidus, sexual dysfunction, amenorrhea, and symptoms of hypothyroidism.
The studies also reported cerebrospinal fluid abnormalities, sudden vision loss among hantavirus patients.
The long-term neurologic consequences of hantavirus remain poorly understood, according to Avindra Nath of the NIH. However, one study found that 20 years after Puumala infection, 78% of patients had persistent hypertension and 8% had chronic kidney disease.
Currently, there are no US Food and Drug Administration (FDA)-approved antiviral treatments or licensed vaccines for hantavirus infection, although several vaccine candidates are in preclinical trials. Several antiviral drugs—including favipiravir, molnupiravir, griffithsin, and ribavirin—have shown promise in early studies, but more research is needed, Nath said.

Nearly all countries are overusing antibiotics—particularly those meant for specific conditions—fueling the global threat of antimicrobial resistance (AMR), according to a study published in The Lancet Public Health.
The study, led by researchers from the Universities of London and Oxford, found that 99% of countries overuse "Watch" antibiotics, while 60% continue to use antibiotics that the World Health Organization (WHO) advises should no longer be prescribed.
"Our findings show the world faces a double challenge – while some antibiotics are being overused, millions of people may still lack access to the medicines they need to treat their infections," said Aislinn Cook, lead author and Senior Research Fellow in Infectious Diseases Epidemiology at City St George's, University of London.

The WHO groups antibiotics into three categories under its AWaRe framework:
In 2024, UN member states agreed that at least 70% of global antibiotic use should come from the Access group by 2030.
Researchers estimated that around 43 billion antibiotic courses were needed globally in 2019—roughly one course per person per year to treat bacterial infections. About 77% of these should have been Access antibiotics, suggesting the UN's 70% target is achievable.
However, analysis of antibiotic use across 67 countries revealed widespread inappropriate prescribing:

The study also highlighted major disparities in antibiotic access. Researchers noted that low- and middle-income countries, which bear a higher burden of infectious diseases and antimicrobial resistance, often need greater access to specialized Watch and Reserve antibiotics.
Yet these medicines are used more frequently in high-income countries, pointing to unequal access rather than clinical need.
A separate study found that antibiotic-resistant bacteria are increasingly leaving children vulnerable to common infections.
The research, led by the Murdoch Children's Research Institute (MCRI) and covering 82 countries, found that antibiotic resistance increased across every region between 2004 and 2022, making many life-saving drugs used to treat common childhood infections less effective.
Published in the Journal of the American Medical Association, the study found that babies, children in intensive care, and those living in countries with limited healthcare resources are the most affected.
Researchers called for stronger national policies to curb unnecessary antibiotic prescribing while ensuring patients who genuinely need specialized antibiotics can access them.
They stressed that improving access will require coordinated action at both local and national levels. This includes:
