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.

The new breast cancer screening guidelines released by the American College of Physicians (ACP) call for mammography screening once every two years in asymptomatic, average-risk adult females, instead of the annual recommendation.
ACP is the largest medical specialty organization in the United States with members in more than 172 countries worldwide.
The guidance statement was developed by ACP's Clinical Guidelines Committee, which defined average risk as females
While the annual mammography has long been considered the standard, in a paper published in Annals of Internal Medicine, the ACP authors explained that the changes have been made to tackle the harms caused by false positive results and the resulting psychological distress.
The false positive results can lead to "overdiagnosis, overtreatment, additional testing, and radiation exposure, and may outweigh the uncertain benefits in this population,” said the ACP.

"This is because the benefits of screening beyond age 74 are reduced or uncertain, while potential harms, such as overdiagnosis, become more likely with increasing age," it said.
"Decisions should consider potential benefits and harms, radiation exposure, availability, patient values and preferences, and cost," the ACP said, while advising against using supplemental MRI or ultrasound for screening in this population.
Breast cancer is one of the leading causes of death in 40–49-year-old women in the United States, and screening is specifically performed to prevent death from breast cancer.
Screening only women ages 50-74 every other year – as called for by ACP – may result in up to 10,000 additional, and unnecessary, breast cancer deaths in the United States each year, said the American College of Radiology (ACR) and the Society of Breast Imaging (SBI) in a joint statement.

Calling the new guidelines “outdated and hyperbolic information”, the statement noted that it will cause continued confusion among women.
"Thousands more women would endure extensive surgery, mastectomies, and chemotherapy for advanced cancers than if their cancers were found early by an annual mammogram,” it said.
Current guidelines from the ACR and the SBI urge women to start annual screening at age 40.
The ACR also recommends that women have a breast cancer risk assessment by age 25. Those at higher risk for breast cancer should talk to their doctor about starting screening before age 40 and additional screening methods -- particularly those with genetic mutations or a strong family history of breast cancer.
The United States Preventive Services Task Force (USPSTF) also urges starting annual screening at age 40 to save lives.
Further, the statement also called out ACP for its failure to recommend exams beyond digital breast tomosynthesis (DBT) for screening women with dense breasts. The statement said this "is also out of step with current research, which shows the need to go beyond DBT to help find cancer in these women".

Three cases of meningitis have been reported among schoolchildren in the Weymouth area in the UK, health officials said.
According to the UK Health Security Agency (UKHSA), of the three cases, two are pupils at Budmouth Academy, Weymouth, and the third attends Wey Valley Academy. The authorities have now rolled out meningitis vaccinations to young people in the region.
The latest outbreak comes after a meningitis outbreak was reported in the Kent region in March, which affected more than 30 people, leaving one sixth-form pupil and a university student dead.
As per the UKHSA, the new cases were confirmed between 20 March and 15 April and are not linked to the deadly Kent outbreak.
The two pupils at Budmouth Academy are contacts of each other, but it is reportedly not epidemiologically linked with the Wey Valley Academy case.
The three cases in Weymouth have been confirmed as Meningitis B (MenB) and are the same sub-strain type, but a different sub-strain to the one detected recently in Kent.
Notably, all pupils in years 7 to 13 in Weymouth, Portland, and Chickerell are to be offered antibiotics and the MenB vaccination.
Close contacts of the cases have already been offered antibiotics as a precaution.

According to UKHSA deputy director Dr Beth Smout, "it is possible that we will see further cases linked to these latest cases in Weymouth".
He stated that the authorities are widening the "offer of antibiotics and vaccination" as "an additional precaution" to reduce the risk of the infection spreading.
"School pupils and staff should attend school as normal if they remain well," the official said.
Meningitis is a serious medical condition that affects the protective membranes covering the brain and spinal cord, the meninges. While fever is not always present, it is usually considered one of the classic symptoms of meningitis.
It is important to know the varied symptoms, causes, and treatments of meningitis for early diagnosis and proper management of the disease.

"If the disease is suspected, you should seek immediate medical attention as the disease can progress rapidly," Smout said.
"The most important short-term thing and the quickest way for people to protect themselves is the antibiotic.
"The vaccine offers longer-term protection. There are two doses, four to six weeks apart, and you are only protected after the second dose," the official said.
A 2026 target trial emulation has found that glucagon-like peptide, also known as GLP-1, which is used by type-2 diabetes patients, can raise the risk of suffering from erectile dysfunction. According to a report published in the European Medical Journal, the impact of GLP-1s on sexual health outcomes in diabetic men has been inconsistent and limited. Erectile dysfunction, however, has been a prominent complication affecting 50 per cent of men with type-2 diabetes over their lifetime.
For this, researchers analysed the electronic health records of men aged 18 years and above with type-2 diabetes in the US from January 2019 to September 2024. Participants were started on treatment with either dipeptidyl peptidase-4 inhibitors (DPP4i) or GLP-1, with 5,524 and 4,910 individuals, respectively. Men with a history of erectile dysfunction diagnosis or end-stage renal disease were not part of the study population. The mean age of these men was 63 years, and the average BMI was 32.8—55 per cent of participants were White, and 23 per cent were Black. GLP-1 users were younger and had a higher prevalence of obesity compared to DPP4i users.
Experts involved in the study found that the incidence of erectile dysfunction in the GLP-1 group was about 35 cases per 1,000 person-years. In the case of DPP4i users, the number dropped to 28 per 1,000 person-years. Hence, people in the GLP-1 cohort had a 26 per cent higher risk of developing erectile dysfunction over a three-year follow-up period. Results were consistent across subgroups; however, they lacked statistical significance after adjustment for negative outcomes.
Researchers noted that the findings of the target trial emulation suggest that sexual health outcomes must be considered in diabetic men, especially those dealing with type-2 diabetes and undergoing treatment with GLP-1 drugs. These findings also highlight the need for randomised trials with standardised erectile dysfunction assessments to further investigate biological pathways.
Type-2 diabetes can cause the following complications in men:
