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

El Salvador Becomes First Country In Central America To Eliminate Trachoma: WHO

Updated Jul 14, 2026 | 11:00 AM IST

SummaryTrachoma is a bacterial eye infection caused by Chlamydia trachomatis. It can spread from person to person through contaminated fingers, fomites and flies that could come into contact with discharge from the eyes or nose of an infected person.

The World Health Organization (WHO) has validated El Salvador for eliminating trachoma, the world's leading infectious cause of blindness, as a public health problem.

El Salvador is the first country in Central America and the second in the Americas to achieve this milestone.

"I congratulate El Salvador on this remarkable achievement. It is a testament to the power of political commitment, strategic investment, and community engagement," said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

"El Salvador's success is a vital step towards our global target of eliminating trachoma worldwide by 2030 and a clear signal that a healthier, more equitable future is within reach," he added.

Between 2023 and 2026, El Salvador conducted targeted assessments in communities identified as at higher environmental and social risk. The surveys found no evidence of active trachoma transmission.

As per the WHO, "no cases of active disease were detected in children, and no adults were found to have advanced trachoma capable of causing blindness". These findings confirmed that trachoma is no longer a public health problem in the country, the UN health agency said.

El Salvador's achievement was supported by a coordinated approach that included:

  • Strengthening primary healthcare services
  • Improving water, sanitation and hygiene (WASH)
  • Expanding eye health services, including adult vision screening
  • Collaboration between government agencies, communities and international partners

The country has also established trained health personnel, integrated surveillance systems and the capacity to detect and treat trichiasis—the advanced stage of trachoma in which eyelashes turn inward and can lead to blindness.

What Is Trachoma?

Trachoma is a bacterial eye infection caused by Chlamydia trachomatis. It can spread from person to person through contaminated fingers, fomites and flies that could come into contact with discharge from the eyes or nose of an infected person.

Environmental risks like poor hygiene, overcrowded households, and inadequate access to water and sanitation facilities can also lead to trachoma.

Repeated infections can scar the inner eyelid, causing the eyelashes to turn inward—a condition known as trichiasis. Without treatment, the eyelashes scratch the surface of the eye, potentially leading to irreversible blindness.

Trachoma Still Persists In Parts Of The Americas

Although El Salvador has eliminated trachoma as a public health problem, the disease remains endemic in rural and remote areas of Brazil, Colombia, Guatemala and Peru.

WHO recommends that countries maintaining elimination continue surveillance and ensure access to quality eye care services to prevent the disease from re-emerging.

WHO Criteria For Elimination

WHO defines elimination of trachoma as a public health problem based on three key criteria:

  • Trichiasis prevalence of less than 0.2% among people aged 15 years and older.
  • Active trachoma (trachomatous inflammation–follicular) prevalence of less than 5% among children aged 1–9 years in every previously endemic district.
  • A functioning health system capable of identifying and managing new trichiasis cases.

With this achievement, El Salvador joins 64 countries worldwide that have been validated by WHO for eliminating at least one neglected tropical disease. Seven of these countries are in the Americas.

US Appeals Court Revives Over 500 Tylenol Lawsuits Over Autism Claims

Updated Jul 14, 2026 | 11:08 AM IST

SummaryThe lawsuits gained attention after President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. issued guidance last year discouraging pregnant women from using acetaminophen, citing it as a possible contributor to autism.

While there is no firm scientific evidence linking Tylenol use during pregnancy to autism, a US federal appeals court has revived more than 500 private lawsuits against the painkiller's maker, Kenvue, over claims that prenatal exposure to acetaminophen contributed to autism and attention-deficit/hyperactivity disorder (ADHD) in children.

The ruling does not determine that Tylenol causes autism or ADHD. Rather, it held that expert testimony supporting the plaintiffs should not have been excluded from the lawsuits.

What Did The US Appeals Court Say

On July 13, the 2nd US Circuit Court of Appeals in Manhattan overturned a December 2024 ruling by US District Judge Denise Cote, who had dismissed the lawsuits after rejecting the methodology of the plaintiffs' expert witnesses.

In its 64-page decision, the three-judge panel said the district court had improperly excluded expert testimony from three doctors presented by parents and guardians seeking to link prenatal Tylenol use with autism and ADHD.

Circuit Judge Guido Calabresi wrote that the experts' methods reflected approaches used by other scientists and "constitute acceptable interpretations of scientific evidence where scientists may, and in fact do, disagree."

Court Did Not Rule That Tylenol Causes Autism

The appeals court emphasized that it was not deciding whether acetaminophen causes autism or ADHD, nor was it making any public health determination.

Instead, the ruling focused solely on whether the expert testimony met the legal standards required to be considered in court.

The three experts whose testimony was reinstated include:

  • Andrea Baccarelli, Dean of Harvard University's School of Public Health
  • Eric Hollander, Professor of Psychiatry at Albert Einstein College of Medicine
  • Brandon Pearson, Toxicologist at Columbia University

Ashley Keller, a lawyer representing the families, said the panel unanimously found that the experts had reliably applied accepted scientific methods.

Kenvue Defends Tylenol's Safety

Kenvue, which was spun off from Johnson & Johnson in 2023, said it continues to stand by the safety of Tylenol.

"We stand behind the safety of our product and will continue to defend these cases," the company said in a statement.

Several retailers and pharmacy chains—including CVS, Kroger, Target, Walgreens, and Walmart—have also been named as defendants.

Trump Administration's Remarks Sparked Debate

The lawsuits gained attention after President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. issued guidance last year discouraging pregnant women from using acetaminophen, citing it as a possible contributor to autism.

The remarks triggered concern among expectant mothers and prompted criticism from many healthcare experts and medical organizations, which said the evidence does not support such definitive claims.

Is Acetaminophen Linked to Autism or ADHD?

The scientific evidence remains inconclusive. Some observational studies have reported a possible association between prolonged acetaminophen use during pregnancy and an increased risk of autism or ADHD in children. However, many other studies have found no significant link.

Importantly, an association does not prove that acetaminophen causes these conditions. Researchers note that factors such as maternal illness, genetics, underlying medical conditions, and other environmental influences may also affect a child's neurodevelopment.

As a result, experts say more high-quality research is needed before any causal relationship can be established.

What Do Medical Experts Recommend?

Major medical associations continue to consider acetaminophen the preferred pain reliever and fever reducer during pregnancy when used appropriately.

Doctors advise pregnant women to:

  • Use the lowest effective dose for the shortest necessary duration.
  • Avoid prolonged or unnecessary use without medical advice.
  • Consult their healthcare provider before taking any medication during pregnancy.

Medical societies have also cautioned against avoiding acetaminophen altogether, noting that untreated high fever or severe pain during pregnancy can pose risks to both the mother and the developing baby.

Michigan health officials say that they may have identified the possible source behind one of the largest Cyclosporiasis outbreaks the state has ever recorded. Thousands of people were sickened by a parasitic infection that can cause severe, watery, or even “explosive” diarrhea.

Source Behind Cyclospora Outbreak Traced

On July 13, the Michigan Department of Health and Human Services (MDHHS) announced preliminary findings from its investigation point to lettuce or other salad greens as the possible source of Cyclospora outbreak.

However, officials stressed that the investigation is in progress, and no specific product, grower, distributor, or supplier has yet been identified for certain.

Health officials also interviewed more than 1,000 patients to identify common exposures.

Early analysis also repeatedly identified lettuce and salad greens as foods consumed before illness, prompting the state to issue precautionary guidance while the investigation continues.

"Although we do not have a definite product identified as the source of the outbreak, we want to let Michiganders know what we have learned so far so they can take steps to protect their families," said Dr. Natasha Bagdasarian, Michigan's chief medical executive, in a state statement.

Cyclospora Cases Continue To Surge

The outbreak has continued to expand at an extraordinary pace since late June. As of July 13, Michigan reported 2,640 cases of Cyclosporiasis, with 44 hospitalizations.

No deaths have been reported so far. The number represents a dramatic increase from the state's usual annual number, which is around 40 to 50 cases.

Preventing Cyclospora

Cyclospora is a parasite that infects people after they consume food or water contaminated with human feces containing the parasite's eggs (oocysts).

Although the illness is usually not life-threatening, it can cause prolonged diarrhea, stomach cramps, nausea, fatigue, bloating, and weight loss.

According to recent reports, fresh produce like salad greens and lettuce are being considered the most common source of infection, though contaminated water can also spread the parasite.

Health officials have advised people to avoid fresh produce. Previous Cyclospora outbreaks in the US have frequently been linked to imported fresh produce, including:

  • Basil
  • Cilantro
  • Mesclun lettuce
  • Raspberries
  • Snow peas

How To Clean Fresh Produce Safely?

While washing produce cannot eliminate all risks, experts say it can reduce contamination. They advised washing fruits and vegetables thoroughly under clean running water and washing hands before and after handling fresh produce.

According to the Michigan Department of Health and Human Services, cooking produce whenever possible during an active outbreak is crucial, as heating food to at least 158°F (70°C) kills Cyclospora.

For specific produce, it suggested:

  • Cilantro and basil: Separate the leaves and rinse each thoroughly under running water.
  • Green onions: Trim off the roots, remove the outer layer, and rinse well.
  • Snow peas: Rub the surface gently while washing under running water.
  • Raspberries: Because of their delicate, uneven surface, raspberries are difficult to clean thoroughly. Cooking them in pies or jams is safer. Freezing may reduce the number of parasites but is unlikely to eliminate them completely.
  • Leafy greens: If possible, choose whole heads of lettuce instead of bagged salad mixes. Discard the outer leaves and wash the remaining leaves under running water before eating.
