The US Food and Drug Administration has approved TNKase or Tenecteplase, which is a thrombolytic or clot-dissolving agent, for the treatment of acute ischemic stroke in adults.

Ischemic strokes happen when a blood clot blocks a blood vessel in your brain. It can cause permanent brain damage and death. If enough brain cells die, you can also lose the abilities or body functions those cells control. They are also the most common types of stroke, with 80% of all strokes being ischemic strokes.

How is TNKase administered?

It is delivered as a single five-second intravenous bolus, which is faster than the standard of care Activase or alteplase, which is administered as an intravenous bolus followed by a 60-minute infusion. The manufacturer of TNKase, Genetech said a new 25-mg vial configuration will also be available in the coming months.

How Was TNKase approved?

The approval came at the backdrop of a study that compared TNKase to Activase in patients with acute ischemic stroke. These patients also presented with a disabling neurological deficit. Results show that TNKase was comparable to Activase in terms of efficacy and safety.

How Common Are These Strokes?

In the United States it self, it affects more than 795,000 people each year and is the leading cause of long-term disability. It is also the fifth leading cause of death. Since brain damage can happen if this progresses rapidly, one needs an immediate, fast-acting medical care.

TNKase thus provide a faster and simpler administration which can be critical for anyone. The chief medical officer and head of global product development at Genetech, Levi Garraway, MD., PhD., said, "Today's approval is a significant step forward and underscores our commitment to advancing stroke treatment options for patients."

What Are The Symptoms Of Ischemic Strokes?

Some of the most common symptoms include weakness or paralysis on one side of your face and body. You may also feel trouble speaking or have loss of speech, also known as aphasia. You may faced slurred or garbled speaking, also known as dysarthria. Other symptoms include loss of muscle control on one side of your face, or sudden worsening or loss of your senses, including vision, hearing, smell, taste, and touch.

Other symptoms include:

  • Loss of coordination or clumsiness
  • Blurry vision or double vision
  • Dizziness or vertigo
  • Nausea and vomiting
  • Neck stiffness
  • Mood swings or sudden personality changes
  • Confusion or agitation
  • Seizures
  • Memory loss (amnesia)
  • Headaches which are sudden and severe
  • Passing out or fainting
  • Coma

Are There Any Warning Signs?

While these are symptoms one has who is prone to this condition. However, often, many may confuse it with other illnesses. It is best to keep an eye out for warning signs. These could be looking out for yourself or your loved one. Note if there is a sudden loss of balance. Look out for sudden vision loss or changes in one or both eyes. Look for a droop on one or both sides of your face, especially when you smile. Raise both arms and see if one arm sags or drops in a way it usually does not. Note for your speech. Are you as fluent? Are you have trouble speaking? If you see any of such signs, start tracking it and talk to your healthcare provider.

A U.S. humanitarian worker in the Democratic Republic of the Congo (DRC) has tested positive for Ebola, raising fresh concerns as the country struggles with one of the worst Ebola outbreaks.

US Humanitarian Worker In DRC Tests Positive For Ebola

On Friday, the U.S. Centers for Disease Control and Prevention (CDC) confirmed, saying it is working closely with the individual's employer, U.S. government health agencies, and Congolese health authorities to prevent further transmission by tracing contacts to identify people who may have been exposed.

According to reports, the infected individual was working for a humanitarian organization in eastern Congo, where the outbreak has continued to spread despite ongoing response efforts.

The CDC has not released details about the patient's identity or condition but emphasized that contact tracing and public health measures are underway.

A spokesperson for the U.S. State Department said it is aware of the case and is assisting the affected American.

The spokesperson said, “A U.S. citizen working for a humanitarian organization in the Democratic Republic of the Congo has tested positive for the Bundibugyo strain of the Ebola virus. The CDC is working with the patient's employing organization, other federal agencies and partners in the Democratic Republic of the Congo to help prevent further transmission and identify high-risk contacts.”

The health regulatory body further said, “The risk of Ebola spreading in the United States remains low.”

Ebola Outbreak In DRC: Latest Updates

The case comes as the Democratic Republic of the Congo faces an escalating Ebola crisis. According to the Africa CDC, the outbreak has now reached 1,830 confirmed cases and 648 deaths, making it the fastest-growing Ebola outbreak ever recorded on the continent. The outbreak was officially declared on May 15, 2026, and has spread across multiple provinces in eastern Congo.

Health officials say this outbreak is particularly concerning because it is caused by the Bundibugyo strain of the Ebola virus, a rare variant for which there is currently no approved vaccine or specific antiviral treatment.

WHO Says Actual Number Of Cases Could Be Higher

The World Health Organization (WHO) has also warned that the official case count may significantly underestimate the true scale of the outbreak.

WHO modeling suggests that actual infections could be two to four times higher than reported because many cases are not being detected.

Nearly 80% of newly identified infections in some of the hardest-hit communities cannot be linked to known Ebola patients, indicating widespread community transmission.

The agency also reported that about 70% of deaths early in the outbreak occurred outside treatment centers, making surveillance and contact tracing even more difficult.

WHO Emergencies Director Chikwe Ihekweazu told Reuters, “Eighty percent of the new patients confirmed are coming outside of known contact lists” in Bunia, the epicenter of the outbreak, highlighting widespread undetected transmission.

He also warned, “The true scale of the outbreak is likely two to four times larger than the official figures suggest.”

The latest case highlights the dangers faced by frontline aid workers and underscores the urgency of strengthening outbreak control measures before the virus spreads further.

With no approved vaccine for the Bundibugyo strain and transmission continuing in several provinces, global health officials say rapid detection, isolation, and international cooperation remain essential to bringing the outbreak under control.

Health officials in England have confirmed that an adult with an underlying immunological condition has died from measles, marking the third measles-related death this year after two children died in June.

According to the latest figures from the UK Health Security Agency (UKHSA), England has recorded 883 confirmed measles cases between the start of the year and July 6. More than half of the cases have been reported in London, with most infections occurring in children aged 10 years and under.

All regions of England, including London (52 per cent), the West Midlands 17 per cent, and the North West 10 per cent, have now reported measles cases.

The UK was declared measles-free in 2017 but lost that status in 2019 after vaccination rates declined and outbreaks resumed.

In January, the World Health Organization (WHO) confirmed that the UK was no longer considered to have eliminated measles, citing stagnant vaccination coverage and rising case numbers.

In response to the surge in infections, NHS leaders have launched a nationwide catch-up campaign targeting children aged two to 11 years who have missed one or both doses of the measles, mumps and rubella (MMR) vaccine.

The program will contact around one million families whose children are not fully vaccinated.

  • GPs will contact parents of children under six.
  • Families with children aged six to 11 will be contacted through the NHS App, text message, email or letter.

Current figures show that 84.1% of five-year-olds in England had received both doses of the MMR vaccine during the first three months of the year—well below the 95% coverage recommended to prevent outbreaks.

"We urge all parents to ensure their children are up to date with their MMR or MMRV vaccines, giving them the best and safest protection against measles," said Dr Vanessa Saliba, consultant epidemiologist at UKHSA.

"Anyone who has missed their measles vaccines can catch up through their GP practice, whatever their age. Getting vaccinated also helps protect babies who are too young to be vaccinated and people who cannot receive the vaccine because of certain health conditions," Dr Saliba added.

Measles (rubeola) is one of the world's most contagious viral infections. It spreads through respiratory droplets released when an infected person coughs or sneezes and can also spread by touching contaminated surfaces before touching the eyes, nose, or mouth.

Symptoms usually develop 7 to 14 days after exposure and include:

  • High fever
  • Cough
  • Runny nose
  • Red, watery eyes
  • Small white spots inside the mouth (Koplik spots)
  • A red rash that typically starts on the face before spreading across the body

While many people recover fully, measles can cause serious complications, including pneumonia, encephalitis (brain inflammation), hearing loss, and, in rare cases, death.

All About the MMRV Vaccine

The MMRV is a safe, live-attenuated immunizations that protect against severe viral infections. The shot combines Measles, Mumps, and Rubella, and also adds protection against Varicella (chickenpox).

According to the UKHSA, children receive:

  • First dose: At 12 months, alongside MenB and pneumococcal (PCV) vaccines.
  • Second dose: At 18 months, alongside the fourth 6-in-1 vaccine.

Children who miss these doses can receive a catch-up vaccination at their 3-year and 4-month appointment. The MMRV vaccine contains weakened forms of the measles, mumps, rubella, and chickenpox viruses, which stimulate immunity without causing disease.

Two MMRV vaccines are available:

  • ProQuad (contains porcine gelatine)
  • Priorix Tetra (does not contain porcine gelatine).

​Experts Say US Cyclospora Parasite Outbreak Is Unusual: How To Clean Fresh Produce

Updated Jul 10, 2026 | 05:25 PM IST

Summary​Experts also warned that the reported infections may represent only the "tip of the iceberg," with additional cases expected in the coming weeks, because the infection takes long to manifest.

An outbreak of Cyclospora, a microscopic parasite that causes prolonged watery diarrhea, has sickened more than 1,400 people across the United States, with infectious disease experts describing the surge in cases as "definitely abnormal."

While the US Centers for Disease Control and Prevention (CDC) is still investigating the source, officials believe the outbreak is likely linked to multiple sources of contamination rather than a single food product.

Health officials in Michigan have reported 1,251 Cyclospora infections, a dramatic increase from around 170 cases recorded on June 30. The state typically reports only about 50 cases annually.

Ohio has confirmed nearly 200 cases, while New York, Illinois, Indiana, North Carolina, and Texas have also reported an increase in infections. More than 40 people have been hospitalized.

Dr. Thomas Moore, an infectious disease specialist and clinical professor of medicine at the University of Kansas School of Medicine-Wichita, described the spike as "definitely abnormal" and concerning, according to The New York Times.

Keith R. Schneider, professor of food safety at the University of Florida, noted that Cyclospora infections usually increase between May and August in the United States. However, he said the current surge—particularly in Michigan—is far beyond what is normally expected.

"Something is going on right now in that area," Schneider told The New York Times.

Experts also warned that the reported infections may represent only the "tip of the iceberg," with additional cases expected in the coming weeks, because the infection takes long to manifest.

What Is Cyclospora And How Does It Spread?

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

Unlike many foodborne bacteria, Cyclospora infections often takes two days to two weeks or more to cause illness after exposure, making it difficult for investigators to identify the original source.

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

Fresh produce is the most common source of infection, though contaminated water can also spread the parasite. Health officials have not advised people to avoid fresh produce, as investigators have not yet identified the exact food responsible for the current outbreak.

Yet, previous US Cyclospora outbreaks have frequently been linked to imported fresh produce, including:

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

Handwashing Matters More Than Hand Sanitizer

Experts emphasize that proper handwashing with soap and water remains one of the most effective ways to reduce the risk of infection.

Alcohol-based hand sanitizers do not kill Cyclospora, making soap and water essential after using the bathroom and before preparing or eating food.

"This type of parasite doesn't easily go away with alcohol-based hand sanitizer. So, good old handwashing is really key here," ABC News medical correspondent Dr. Darien Sutton said.

How To Clean Fresh Produce Safely

While washing produce cannot eliminate all risk, 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.
