After mpox outbreak, Africa is under the threat of yet another virus outbreak, this is the Marburg virus outbreak in Rwanda. So far, six people have died from the outbreak, confirmed the health minister. Most victims were the healthcare workers in the hospital's intensive care unit. As per reports, 20 cases have been identified since the outbreak was confirmed on Friday.

What Is Marbug Virus?

With the fatality rate of 8% it is the same virus family as Ebola. The main carrier is from fruit bats which spreads to humans then through the contact of bodily fluids of infected individuals, it spreads to others.

Common Signs And Symptoms

The common signs and symptoms of the Marburg virus include fever, pain, diarrhoea, vomiting and in the case of extreme blood loss, death too can happen.

So far, there is no specific treatment or vaccine for the virus. However, treatments like drugs and immune therapy are being developed as per the World Health Organisation (WHO).

Call Of Action

Rwanda says that it has intensified its contact tracing, surveillance and testing to contain the spread. It has also tracked about 300 people who had come into contact with individuals affected by the Marburg virus.

The health minister has urged people to stay vigilant and avoid any physical contact and to wash their hands with clean water, soap or sanitiser and report any suspected case.

As of now, most of the cases have spread to the capital in Kigali. In light of this, the US Embassy in the city has advised its employees to work remotely for the next week.

This is the first time Rwanda has confirmed for Marburg cases, before this, in 2023, Tanzania confirmed the outbreak, whereas three people had died of this in Uganda in 2017.

History Of Marburg

As per WHO, this virus kills half of the people it infects. In the previous outbreaks, it has killed between 24% to 88% of the patients.

The virus was first detected in 1976 after 31 people were infected, out of which 7 died in simultaneous outbreak in Marburg and Frankfurt in Germany, and Belgrade in Serbia.

The source was traced to African green monkeys who were imported from Uganda. However, other animals too are linked to the virus spread, including bats.

In the past, the virus outbreaks have happened in countries like Equatorial Guinea, Ghana, the Democratic Republic of the Congo, Kenya, South Africa, Uganda, and Zimbabwe. In 2005, this virus killed 300 people in Angola.

However, for the rest of the world, only two people have died from the virus in the rest of the world, with one of them being in Europe, and the other in the US. These both have been on expeditions to caves in Uganda.

A diarrheal illness caused by the parasite Cyclospora cayetanensis is spreading across multiple US states, with federal health officials reporting a higher-than-expected number of cyclosporiasis cases this summer. While several outbreaks have been identified, investigators have yet to pinpoint a common source.

The US Centers for Disease Control and Prevention (CDC) is investigating clusters of infections in Illinois, New York, Pennsylvania, Texas, Michigan, Ohio, Alabama, Kentucky, Tennessee, Virginia and West Virginia. Some clusters have been linked to Mexican-style restaurants, a grocery chain and a catered event, but officials say there is no evidence yet that they are part of a single nationwide outbreak, CNN reported.

Meanwhile, the US Food and Drug Administration (FDA) is tracing fresh produce, including white and green onions, cucumbers and cilantro, as potential sources of contamination.

Michigan has reported the largest outbreak so far. As of July 6, the state had confirmed 678 cases of cyclosporiasis, according to the Michigan Department of Health and Human Services (MDHHS). The state typically records around 50 cases annually, making this year's outbreak more than 13 times higher than normal.

Ohio has also seen a sharp rise, reporting 177 cases as of July 2. Nearly 171 of those infections were recorded after June 20, with cases confirmed across 43 counties.

Nationally, excluding Michigan, the CDC reported 145 confirmed cases across 17 states between May 1 and June 16. At least 20 people have been hospitalized, though no deaths have been reported. Patients ranged in age from 5 to 86 years, with a median age of 42, and about 61% of cases were reported in women.

Why Is It So Difficult To Find The Source?

Experts say Cyclospora cayetanensis is much harder to trace than common foodborne bacteria such as E. coli and Salmonella.

Investigators often rely on DNA fingerprinting to connect bacterial infections to contaminated food through laboratory networks such as PulseNet. However, this approach is far less effective for Cyclospora because the parasite has a far more complex genetic makeup, making it difficult to link cases to a single food item or supplier.

Dr. Max Teplitski, former head of the Division of Food Safety at the US Department of Agriculture and now chief science officer at the International Fresh Produce Association, said the parasite remains one of the most difficult foodborne pathogens to investigate, contributing to delays in identifying the outbreak source, CNN reported.

How To Prevent Cyclospora Infection

The CDC recommends the following precautions to reduce the risk of infection:

• Wash your hands thoroughly with soap and water before and after handling fresh produce.
• Rinse fruits and vegetables under running water before eating, cutting or cooking them.
• Do not rewash produce labeled "prewashed."
• Scrub firm produce, such as melons and cucumbers, with a clean produce brush.
• Cut away bruised or damaged portions before eating.
• Refrigerate cut, peeled or cooked fruits and vegetables within two hours.

Cyclospora spreads through food or water contaminated with human feces and is not transmitted directly from person to person.

Dr. Darien Sutton, an emergency medicine physician and ABC News medical correspondent, stressed that proper handwashing is essential because alcohol-based hand sanitizers are not effective against the parasite.

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

The US Food and Drug Administration (FDA) has announced a recall of organic frozen blueberries sold at Publix stores across eight US states after they were linked to a potential outbreak of E. coli infections.

GreenWise Organic IQF Blueberries were first recalled by Frutas y Hortalizas del Sur S.A. of San Carlos, Chile, which supplied the product to grocery chain Publix. Publix then recalled the frozen blueberries from its stores on July 3, 2026, according to a company statement.

According to FDA, the outbreak has resulted in 12 confirmed cases of E. coli-related gastrointestinal illness, including four hospitalizations. The FDA also said it has received reports of illness after consumers ate the frozen blueberries.

While many strains of E. coli are harmless, the bacteria involved in this recall is Shiga toxin-producing E. coli (STEC).

"E. coli O145 is a Shiga toxin-producing E. coli (STEC) that can cause illness characterised by severe stomach cramps, diarrhoea (which may be bloody), and vomiting," the FDA said.

The agency added that although most healthy people recover within a week, some infections can lead to hemolytic uremic syndrome (HUS), a serious complication that can cause kidney damage, particularly in young children, older adults, and people with weakened immune systems.

• Georgia
• Kentucky
• North Carolina
• South Carolina
• Tennessee
• Virginia

Which Blueberries Are Being Recalled?

The FDA advises consumers to check their freezers for the following product:

• Product: Frozen GreenWise Organic IQF Blueberries
• Package Size: 10 oz
• Lot Code: 60401
• Best By Date: February 9, 2028

Consumers who have the affected product should not eat it. Frutas y Hortalizas del Sur S.A. said it is working closely with regulatory authorities and customers. The company has instructed all customers who received the affected lot to immediately isolate the product, stop distributing it, and notify any downstream customers.

What Is E. coli?

Escherichia coli (E. coli) is a group of bacteria that normally lives in the intestines of humans and animals. Most strains are harmless and help with digestion. However, certain strains produce toxins that can cause serious illness when ingested through contaminated food or water.

What Happens During an E. coli Infection?

An E. coli infection most commonly affects the digestive system, causing:

• Watery diarrhoea
• Severe abdominal cramps
• Gastroenteritis
• Vomiting
• Mild fever
• Loss of appetite

Some infections, particularly those caused by Shiga toxin-producing E. coli, can lead to hemolytic uremic syndrome (HUS), a potentially life-threatening condition that damages the kidneys.

How to Protect Yourself From E. coli

You can reduce your risk of E. coli infection by:

• Washing your hands thoroughly with soap and water.
• Handling raw and cooked foods separately.
• Cooking food, especially meat, thoroughly.
• Washing fruits and vegetables before eating.
• Drinking safe, clean water and avoiding unpasteurised products.

The single overnight sleep study, usually conducted to diagnose obstructive sleep apnea (OSA) may not be accurate enough, according to a recent study. Sleep patterns change significantly from one night to the next, meaning current one-night testing could underdiagnose or overestimate the condition in some patients.

The study, published in the journal npj Digital Medicine, challenges the long-standing practice of relying on a single overnight sleep study, also known as polysomnography, to diagnose OSA.

How Was The Study Conducted?

Obstructive sleep apnea is a common sleep disorder in which breathing repeatedly stops and starts during sleep due to blockage of the upper airway. If left untreated, it has been linked to serious health problems, including high blood pressure, cardiovascular disease, type 2 diabetes, stroke, and reduced quality of life.

To investigate whether a single sleep study accurately reflects a person's condition, researchers studied about 100 adults for suspected sleep apnea.

Participants underwent standard overnight polysomnography, a gold-standard diagnostic test. Simultaneously, they also had their sleep monitored repeatedly over several weeks in their home environment.

The researchers then compared the results from the one-night test with the average findings collected across multiple nights.

Is The Single-Night Sleep Apnea Test Reliable?

The analysis revealed significant night-to-night variation in sleep apnea severity. In many cases, the severity measured during one laboratory night did not match the average severity recorded over multiple nights.

As a result, some patients could get classified into the wrong severity category due to the one-night test, particularly those whose sleep apnea naturally fluctuates or whose sleep is easily affected by the unfamiliar environment.

Lead author Dr Bastien Lechat, a sleep expert at FHMRI Sleep Health, said, “Our findings show that sleep apnea can vary considerably from one night to the next, so if you only measure it once, you may not capture the true severity of the condition. In some participants, we saw clear differences between the single-night result and the average across multiple nights, which suggests current diagnostic approaches may under- or overestimate disease severity in some individuals.”

The researchers also found that patients whose classifications changed between the types of tests often experienced poorer sleep during laboratory testing. This indicated that an unfamiliar sleep environment may alter sleep quality and influence results.

Senior author Professor Sutapa Mukherjee, Professor of Respiratory and Sleep Medicine at Flinders University and Senior Consultant at Southern Adelaide Local Health Network (SALHN), said, “Our findings show that sleep apnea is a dynamic disorder, and by capturing how it changes over time, we can build a much more accurate and clinically meaningful picture of a patient's condition.”

The researchers also believe that monitoring sleep on multiple nights can help doctors assess a patient's future health risks and course of treatment in a better way.

While further research is needed before multi-night monitoring becomes routine clinical practice, the authors believe the study marks an important step toward modernizing sleep apnea diagnosis.
