Disease X be the source of the next global health crisis.

Disease X be the source of the next global health crisis.

Disease X WHO says that SARS, Nipah, or Ebola, might be the source of the next global health crisis. Researchers are closely monitoring nine pathogens.

The World Economic Forum’s annual meeting, which takes place in Davos, Switzerland, next week, is drawing more attention than normal this year because of a session titled “Preparing for Disease X.”

Disease X be the source of the next global health crisis.

Disease X, what is it?

As per the World Health Organization, “Disease X” signifies the understanding that a potentially deadly global pandemic may be triggered by a pathogen that is not yet recognized to cause illness in humans.

In fact, among the speakers at the event will be Director-General Tedros Adhanom Ghebreyesus of the organization, Michel Demaré, the chair of the AstraZeneca board, Brazil’s Minister of Health Nisia Trindade Lima, and Jamil Edmond Anderlini, chief editor of Politico Europe.

Late this week, the routine pandemic preparation exercise was exaggerated to the point where the term “Disease X” briefly trended on Google and Twitter.

On social media, right-wing accounts attacked the meeting, claiming that world leaders would meet to talk about plans to impose vaccination laws, censor expression, and even organize pandemics.

Fox News analyst Monica Crowley, a former assistant secretary for public affairs under President Trump, tweeted a bogus warning on Thursday night stating that “unelected globalists at the World Elected Forum will hold a panel on a future pandemic 20x deadlier than COVID.”

“A new epidemic to allow them to implement a new WHO treaty, lockdown again, restrict free expression, and kill more freedoms, just in time for the election,” the writer stated. Seem unrealistic? Thus, did the events of 2020.

Physicians and public health professionals “have always conducted thought experiments and tabletop exercises to prepare for pandemics,” according to Dr. Amesh Adalja, senior scholar at the Johns Hopkins Center for Health Security, who speaks with Fortune.

According to him, these activities are essential for determining one’s strengths and shortcomings as well as for emphasizing critical reaction elements that require more development.

For the nihilistic goal of undermining pandemic preparedness and blatantly pandering, he continued, “to arbitrarily suggest these exercises and meetings are part of some kind of conspiracy that evades the actual purpose they serve and the problems on which they are trying to gain traction.”

It would be “irresponsible” for world leaders to skip the forum, according to Dr. Stuart Ray, vice chair of medicine for data integrity and analytics at the Johns Hopkins Department of Medicine, who spoke with Fortune.

“History has seen many such incidents, and the current coronavirus pandemic has shown us that prompt action can save millions of lives,” the speaker stated. “Public health response coordination is just responsible planning; it’s not a conspiracy.”

“Such planning requires oversight, appreciation for personal impact on personal and economic freedom, and impact on special populations,” he continued, adding that such discussions had to be made public.

“It makes sense to involve leading scientists, interested private individuals, and a global public health organization.”

“Priority pathogens” according to the WHO, excluding Disease X

“Priority pathogens” are those that “pose the greatest public health risk due to their epidemic potential and/or whether there are no, or insufficient, countermeasures” that are kept on file by the World Health Organization.

The group stated that an updated list, which was last updated in 2018, was anticipated last year and is currently anticipated in the first half of 2024.

Here are the known diseases that, in addition to “Disease X,” global public health professionals are keeping a watch on. The list is by no means comprehensive, and it does not always point to the most likely source of the next epidemic or pandemic.

Marburg virus infections and Ebola

Hemorrhagic fevers, also known as bloody fevers, are caused by viruses in this family and are usually accompanied by internal organ or bodily orifice bleeding. In addition to the highly similar Marburg virus that made news during an outbreak in Equatorial Guinea earlier this year, the family includes five strains of Ebola.

According to the WHO, the average death rate from Ebola is around 50%, while case fatality rates have varied from 25% to 90%. In addition, Marburg kills about 50% of individuals it infects; however, case fatality rates vary from between 24% to 88%, according to experts.

There are two approved vaccinations against Zaire, the deadliest variant of Ebola; however, there are none available against the other four strains. However, there isn’t a licensed vaccination against Marburg.

Congo-Crimean Hemorrhagic fever

Crimean-Congo hemorrhagic fever is an acute viral hemorrhagic sickness similar to Ebola and Marburg that can induce bleeding from body orifices.

The fever, headache, sore eyes, disorientation, neck discomfort, back pain, muscle ache, and light sensitivity are some of the symptoms that can appear suddenly. Sharp mood changes and confusion may follow nausea, vomiting, diarrhea, stomach discomfort, and sore throat.

According to the WHO, agitation may become sleep, depression, and lassitude two to four days later; abdominal discomfort may center in the upper right quadrant; and the liver may grow.

Additional symptoms could be an elevated heart rate, swollen lymph nodes, and a petechial rash on the skin and internal mucosal surfaces like the mouth and throat, which is brought on by bleeding into the skin. The rash might spread.

Usually, hepatitis is present. Patients may experience organ failure, such as failure of the liver, kidneys, or lungs, after the fifth day of illness.

This disease, which is transmitted by ticks and the tissue of infected animals during and after slaughter, has a case fatality rate of about 30%. The majority of patients pass away within their second week of sickness.

Fever Lassa

Lassa fever is an acute viral hemorrhagic infection, similar to Ebola, Marburg, and Crimean-Congo hemorrhagic fever. However, it’s significantly less lethal, with a 1% case fatality rate. Eighty percent of persons infected with Lassa fever do not exhibit any symptoms.

Twenty percent of people have a serious disease. A typical course of symptoms includes fever, weakness, and malaise, which are similar to COVID-19 or the flu.

Other common symptoms include headache, sore throat, muscle soreness, chest discomfort, nausea, vomiting, diarrhea, coughing, and stomach pain.

Along with shock, seizures, tremors, disorientation, and coma, other possible symptoms include facial edema, a build-up of fluid in the lung cavity, and low blood pressure.

Damage to many organ systems occurs frequently. Those who make it through may experience temporary or permanent hearing loss, temporary hair loss, and abnormalities in their gait.

The WHO reports that most virus-related deaths occur within two weeks of commencement. In addition to the fetus, 80% of pregnant women who contract the infection in the third trimester also pass away. Rats

SARS-CoV-1, or Severe Acute Respiratory Syndrome

When SARS-CoV-1 was originally discovered in China in 2002, it resulted in the first coronavirus pandemic in history. Before being contained after seven months, it had spread to more than two dozen nations in Europe, South America, and North and South America.

It is believed that SARS first spread among animals, possibly bats, and subsequently to people via civet cats, a tropical mammal that resembles a cross between a dog and an ocelot. Experts warn that a spillover might occur once more.

Headache, body aches, moderate respiratory symptoms, possibly diarrhea, a dry cough toward the end, and pneumonia are among the symptoms. Between 2002 and 2003, SARS afflicted around 8,100 people, and less than 10% of them died.

SARS has no approved vaccination, but scientists are developing universal coronavirus vaccines that may combat COVID as well as SARS and other coronaviruses.

Coronavirus known as Middle East Respiratory Syndrome (MERS)

The first lethal coronavirus discovered in history was SARS, and the second was MERS. When it was found in Saudi Arabia in 2012, there were roughly 2,500 cases and 800 fatalities.

While MERS cases are still being reported occasionally—three infections and two fatalities were reported in August 2023 in Saudi Arabia—SARS has not been confirmed since 2004.


The world is still experiencing a COVID epidemic, whether it wants to acknowledge it or not, as stated by Dr. Maria Van Kerkhove, chief of WHO’s emerging diseases and zoonoses unit, during a news conference in January.

Although the number of COVID-19 deaths is estimated to be at least three times greater, the official figure is at 7 million.

According to Van Kerkhove, even though the public health emergency of international concern (PHEIC) status expired in May 2023, a WHO committee can decide to reestablish it at any time, particularly if the virus develops into a more serious form. And it is very much conceivable.

“We have serious concerns—deep worries—that this virus is spreading uncontrolled throughout the world and that a more severe variant could emerge at any time,” she stated on Friday. “This isn’t intended to be a deterrent. This is a situation that we budget for.

Nipah and other Henipaviral infections

Nipah is a henipavirus, the most dangerous of paramyxoviruses. The virus was initially discovered in pigs in Malaysia and Singapore during the late 1980s, while fruit bats are its natural host.

In Australia in 1994, Hendra, the other henipavirus that is known to infect humans, was discovered in racehorses and people.

Both have severe flu-like symptoms and a respiratory ailment. They can also develop into encephalitis, or brain inflammation, which can cause various neurologic symptoms as well as death.

Between 45% and 75% of those infected with Nipah die from it. There are currently no approved vaccines; however, Moderna is working with the National Institute of Allergy and Infectious Diseases Vaccine Research Center to examine a potential vaccine.

Fever in the Rift Valley

This virus is well-recognized for wreaking havoc on livestock. It is not currently known to spread from humans to other humans, even though it can spread from animals to humans and other animals to humans. But that might alter as viruses evolve.

Human infections are the result of inoculation, such as cuts from infected knives or breaks in the skin. Aerosols released during the killing of diseased animals can also infect humans.

The WHO states that consuming raw or undercooked milk from sick animals may potentially expose humans to illness. In addition, blood-feeding flies or mosquitoes carrying the illness may attack humans.

When symptoms do appear in persons who are infected, they are usually mild. The abrupt onset of a fever similar to the flu, headache, joint, and muscular discomfort are some of the symptoms.

It’s also possible to experience vomiting, appetite loss, light sensitivity, and neck stiffness. Such cases may be confused for meningitis.

Less than 1% of cases will result in death, and about 3% will develop a severe illness. There are three main types of severe disease: hemorrhagic, meningoencephalitis, and ocular.

Zika infection

Similar to COVID, the WHO previously designated Zika virus-associated microcephaly, a birth abnormality related to the brain, as a PHEIC from February to November of 2016.

The majority of people who contract the virus—which is mostly spread by Aedes mosquitoes—don’t show any symptoms. For two to seven days, those who do typically develop a rash, fever, conjunctivitis, muscle and joint discomfort, malaise, and headache.

Even more concerning is the possibility of infection during pregnancy leading to early birth, miscarriage, and congenital deformities in the resulting child. According to the WHO, it can also cause neuropathy, myelitis, and Guillain-Barré syndrome in adults and children.
