When a possible measles case is identified in California, a phone rings at the local health department and the clock starts ticking.
Laboratory workers need to process samples as soon as possible to confirm the case. And a public health nurse must call the patient to find out where they've been and who they've been in contact with recently.
If test results are positive, the communicable disease team has 72 hours or less to identify anyone who has been exposed and may be at high risk of infection or serious illness. Those people must quarantine or take a dose of a post-exposure prophylaxis to prevent spread. For the next 21 days nurses will monitor the group for symptoms.

Scientists showed in a new study published Thursday that they could use blood draws to build a “clock” for Alzheimer’s disease that could roughly predict when symptoms will develop, findings that could eventually transform how the illness is diagnosed and treated.
A simple blood test can help diagnose Alzheimer’s, but the study in the journal Nature Medicine shows how these kinds of tests could one day play a greater role in preventing the insidious, memory-robbing illness. In the new study, researchers built a model that could use blood test results to forecast symptom onset within a margin of three to four years.

The Food and Drug Administration refused to review Moderna’s application for a new influenza vaccine, the company said Tuesday, a surprise decision that could raise concerns about the agency’s posture toward drug companies and the Trump administration’s policies on vaccines.
Moderna, revealing the rejection, took the unusual step of releasing the letter it had received from Vinay Prasad, who heads the FDA’s biologics division. They also issued a strongly worded statement from its CEO Stephane Bancel, who said the decision “does not further our shared goal of enhancing America’s leadership in developing innovative medicines.”
American doctors are ignoring vaccine guidance from the U.S. government and making the AAP the most visible opposition to the MAHA vaccine agenda.

The measles outbreak in South Carolina reached 876 cases on Feb. 3, 2026. That number surpasses the 2025 outbreak in Texas and hits the unfortunate milestone of being the largest outbreak in the U.S. since 2000, when the disease was declared eliminated here.
The outbreak is exposing the breadth of dangers the disease can pose. South Carolina’s state epidemiologist revealed on Feb. 4 that cases of brain swelling, a rare complication of the disease, had emerged in some infected children, according to Wired magazine.
Feb 8, 2026
Former FDA Commissioner Dr. Scott Gottlieb, who sits on the boards of Pfizer and UnitedHealthcare, told "Face the Nation with Margaret Brennan" that the current measles outbreak could be a "long cycle, especially now that this has gotten embedded in political psyche in this country."

Multiple sclerosis is also caused by a virus carried by almost all humans. A new study provides an explanation as to why only certain people develop the disease. This also opens up the possibility of a treatment.
The Epstein-Barr virus is a herpes virus and is considered a contributory cause of various cancer and autoimmune diseases. It is transmitted via droplets such as in saliva. That's why one of the diseases caused by the virus, Pfeiffer's disease, or Pfeiffer's glandular fever, is also known as the kissing disease.
It has been known for a long time that the Epstein-Barr virus (EBV) is also a contributing cause of multiple sclerosis. The problem, however, is this: Almost every human is infected with EBV and carries it in their body for life. Multiple sclerosis, however, affects less than 1% of the population. How is that possible?
Scientists may now have come closer to solving this mystery. The answer is, as often, hidden in our genes.

Since October, at least 20 million Americans have gotten the flu, the Centers for Disease Control and Prevention reports. That number includes at least 270,000 flu hospitalizations and 11,000 deaths, including 52 pediatric deaths this flu season.
“That is higher, significantly higher, than the last few years,” says Dr. Tyler B. Evans, an infectious disease specialist and CEO of Wellness Equity Alliance, a public health organization for underserved populations. Currently, the most common flu strain infecting people is a strain of the influenza A (H3N2) virus called “subclade K.” It’s responsible for 90% of infections this flu season, and has been deemed by some media outlets as a “super flu.”
The virus — called Nipah — kills more than half of the people it infects. Nipah virus, which was named after the village in Malaysia where the first known patient lived, is part of the same family of viruses as measles. Despite that, it’s not as infectious as measles, but it is significantly more deadly.
By Liu Xuhan Published: Jan. 30, 2026 9:00 p.m. GMT+8
The World Health Organization said the risk of further diffusion from a recent cluster of Nipah virus cases in India remains low, easing concerns about a potential broader outbreak of the deadly pathogen.

It can also be transmitted through contaminated food or directly from human to human. First identified in 1998/9 during an outbreak among pig farmers in Malaysia and Singapore. Evidence that Nipah virus can infect dogs, cats, goats, horses and sheep. Natural hosts of the virus Fruit bats, (flying foxes) particularly those of the Pteropus genus. Symptoms Incubation period, typically 4 to 21 days, (or longer) Sudden onset of non-specific flu-like illness or fever. Pneumonia and other respiratory problems develop. Encephalitis (inflammation of the brain) or meningitis, typically develops 3 to 21 days after initial symptoms. Severe headache, drowsiness, blurred vision, cough, abdominal pain, myalgia Case fatality rate, 40 to 75% Some survivors may be left with lasting neurology difficulties, persistent seizures, personality changes. In rare cases, the virus can reactivate months or even years after the initial infection. Diagnosis Real time polymerase chain reaction (RT-PCR) of respiratory samples, blood or cerebrospinal fluid.

Bangladesh (where cases have occurred almost annually since 2001) India (outbreaks in Kerala since 2018, current outbreak in West Bengal) Malaysia The Philippines Singapore How is Nipah virus transmitted? Direct contact with an infected animal and their secretions Consumption of fruits or fruit products (raw or partially fermented date palm juice), contaminated with the poo, urine or saliva of infected fruit bats. Person-to-person spread Is possible through close contact with an infected person or their body fluids. This has been documented in Bangladesh and India, most commonly among family members and close contacts caring for infected patients. Those with respiratory symptoms may pose a transmission risk. Nipah virus treatment No proven specific treatment for Nipah virus infection No preventative vaccine is licensed for use. Prevention in endemic areas Avoid contact with bats and their environments Avoid contact with sick animals Don't consume raw or partially fermented date palm sap - if consuming date palm juice, ensure it has been boiled first Wash all fruit thoroughly with clean water and peel before eating Avoid fruit found on the ground or fruit that appears to have been partially eaten by animals Good hand hygiene, particularly after caring for or visiting sick people Avoid close, unprotected contact with anyone infected with Nipah virus, including contact with their blood or body fluids In healthcare settings Strict infection prevention and control measures are essential, including contact, droplet and airborne precautions for both suspected and confirmed patients.

South Carolina is battling the country’s largest measles outbreak since the disease was eliminated from the United States more than a quarter century ago, with more than 840 cases overwhelmingly in unvaccinated children and adults.
Three more measles cases have been confirmed in Snohomish County after an outbreak began two weeks ago, public health officials said on Jan. 28. Earlier in January, three children in Snohomish County tested positive for measles after being exposed to a contagious family visiting from South Carolina, where a massive ongoing outbreak has infected nearly 800 people since October. The Snohomish County kids, who are between 23 months and 9 years old, were not vaccinated and are recovering at home.
Two cases of the Nipah virus were confirmed in India's West Bengal state in December, prompting authorities across South and Southeast Asia to step up precautionary measures, including airport screenings.
Nipah virus can cause fever and brain inflammation and, though not highly contagious, carries a high fatality rate, says Kaja Abbas, an associate professor of infectious disease epidemiology.

The South Carolina Department of Public Health (DPH) today confirmed 54 new measles cases in just three days, raising the size of its outbreak, which DPH first reported in October, to 700 cases.
The news comes as the Centers for Disease Control and Prevention (CDC) confirmed 416 total US cases so far this month—an increase of 245 infections in the past week—and as US health officials downplay the burgeoning outbreak and the key role that vaccines play in preventing illness.
The United States, meanwhile, will likely lose its elimination status in the coming months as measles cases spike. It had gained that status in 2000. Last year the CDC confirmed 2,255 cases nationwide, the most since 1991. The agency also confirmed three deaths last year, two involving children.

A particularly bad outbreak in West Texas that began in January of last year was a significant driver of those cases.

After a record week of flu activity in the US, hospitalizations and deaths continue to rise. About 40,000 people were admitted to the hospital with flu during the week ending January 3, according to data published Friday by the US Centers for Disease Control and Prevention, about 10% more than the 36,600 hospitalizations in the week before. Overall, the CDC estimates that there have been at least 15 million illnesses, 180,000 hospitalizations and 7,400 deaths from flu this season. Flu activity “remains elevated across the country,” and the CDC says it expects that to continue for several more weeks. More than a dozen states have flu activity levels in the highest category that the agency tracks. CDC surveillance data published last week showed that flu-like activity in the US had reached the highest level on record since the agency started tracking about 30 years ago.

The Centers for Disease Control and Prevention has reported an estimated 11 million cases of influenza so far this winter--a rate of illness that has led to an estimated 5,000 deaths. Forbes senior editor Alex Knapp joined colleague Maggie McGrath to explain why this year's flu is so contagious and how vaccine skepticism is affecting flu shot adoption.
Respiratory virus activity across the United States has climbed to high levels, driven by increases in influenza and respiratory syncytial virus (RSV) activity, according to the Centers for Disease Control and Prevention’s (CDC’s) weekly respiratory illness update. Meanwhile, COVID-19 levels remain relatively low but show signs of an uptick.
Influenza is everywhere right now.
According to data from the Centers for Disease Control and Prevention, more than half of the country is reporting high or very high flu activity. Flu cases are also expected to continue climbing, meaning even more people will contract the virus.
“Numbers of emergency department visits, outpatient visits, hospitalizations are all on the increase, and it looks like this is mostly driven by numbers in children,” Dr. Robert Hopkins, the medical director of the National Foundation for Infectious Diseases, said. Younger adults with the flu are next, but Hopkins said he suspects cases among older adults will soon make up a larger share of the data.
South Carolina’s measles outbreak exploded with nearly 100 new cases as it became the worst active measles outbreak in the country and has now spread outside the state’s borders.
The S.C. Department of Public Health reported Jan. 9 that the outbreak now has infected 310 people, not counting four children in North Carolina who also have been infected after visiting the outbreak’s epicenter in Spartanburg County. In South Carolina, 200 people are in quarantine and nine are in isolation.

The CDC says a spike in flu cases is driven by a new variant. It comes as vaccination rates remain low.
WASHINGTON — Flu is rising rapidly across the U.S., driven by a new variant of the virus — and cases are expected to keep growing as holiday travel plays out.
That variant, known as “subclade K,” led to early outbreaks in the United Kingdom, Japan and Canada. On Tuesday, the Centers for Disease Control and Prevention reported high or very high levels of illness in more than half of the states.
The CDC estimated there have been at least 7.5 million illnesses in the U.S., 81,000 hospitalizations and 3,100 deaths from flu so far this season. That includes at least eight child deaths, and is based on data as of Dec. 20, prior to major holiday gatherings.

The clinical data company came up with its list by analyzing 65,892 recruiting trials. That breast cancer held the top spot again was no surprise to Gen Li, Ph.D., Phesi’s president and founder.
Breast cancer is one of the most common cancers in the world, and is a “dire disease” with many different subtypes, Li said. Triple-negative breast cancer (TNBC) also had a high rate of phase 2 trial terminations, he added, another focus of Phesi’s report.

Medical Correspondent Dr. Darien Sutton explains what’s driving the flu surge, how children are being affected this season and what treatments work best if you get sick.
Cases of influenza in the United States are rising, driven by a new strain that public health officials worry current vaccines may not protect against as effectively.
Health officials and researchers say that although the flu season has not reached its peak, the spike in cases is not historically unusual — and they stress vaccines probably still offer protection against the worst effects of the strain.
A new version of the flu virus is now driving most infections this season, and cases continue to rise across the United States.
The strain, known as H3N2 subclade K, has quickly become the dominant form of flu detected in testing and is slightly different from the virus targeted by this year’s flu vaccine.
Health officials are warning about a surge in so-called “super flu” cases as a particularly aggressive strain drives higher-than-usual hospitalizations this season. Patients are reporting intense symptoms that can escalate quickly, especially among older adults, young children, and those with weakened immune systems.
South Carolina health officials announced nine new measles cases today in an Upstate outbreak, bringing the outbreak total to 153 and the statewide total to 156 for the year.
“Five of the new cases were known household exposures, two resulted from a previously reported school exposure, the source of one is unknown and one is still being investigated,” officials said in a press release. “There are currently 249 people in quarantine and seven in isolation.”
Cases of the flu are rising across the country with some states getting hit harder than others.
The nationwide hospitalization rate jumped by 14.3% with over 9,900 people admitted with the flu, according to data released on Friday by the Centers for Disease Control and Prevention (CDC).
The number of measles cases in Quebec is growing as an outbreak is underway.
On the morning of Dec. 19, eight cases were confirmed in the Lanaudière region, the Laurentians, Laval, Que., and Montreal, according to the provincial government.
On Sunday morning, Dr. Antonio D'Angelo, the head of the pediatric emergency department at CHU Sainte-Justine, told Radio-Canada there had been two confirmed cases at his Montreal hospital over the past week.
''We are expecting more cases," Dr. D'Angelo said.
Most people in the country know someone who currently has, or just had, the flu.
Flu season arrives with the holidays, as parties and travel kick into high gear and colder weather sets in across many states. Like last year, though, this flu season is shaping up to be a bad one. While levels aren’t at a peak right now, certain regions are currently getting hit hard (and cases are rising overall).
Pennsylvania this year confirmed 16 cases of measles, including in Cumberland County. State health officials are monitoring the situation amid outbreaks in other states.

As measles continues to spread in the United States, it’s likely that the outbreaks that broke records in 2025 will continue into the new year.
In South Carolina, 168 people, mostly schoolchildren, are in quarantine. Most of the state's 138 cases confirmed since September, nearly all in unvaccinated people, have been centered in Spartanburg County in the northwestern part of the state.
Measles is a highly contagious virus. Two doses of the MMR vaccine provide the best protection.

HOUSTON, Texas – Houston-area health officials are raising concerns over a significant increase in whooping cough cases, also known as pertussis, across Texas.
According to state data, Texas has reported more than 3,500 pertussis cases so far this year, a sharp jump from just 340 cases in 2023. The Houston Health Department says those numbers could continue to climb as families gather and travel during the holiday season.
A new version of the common flu is spreading globally, and health officials are monitoring this evolving strain of influenza A(H3N3) Subclade K, which has been increasingly detected worldwide.
Seasonal influenza activity has increased globally in recent months, with influenza A viruses accounting for the majority of detections, according to the World Health Organization.
CDC • MMR vaccine is very effective at protecting people against measles, mumps, and rubella, and preventing the complications caused by these diseases.
The measles outbreak in South Carolina is “accelerating” with no end in sight following Thanksgiving and other large gatherings, state health officials said Wednesday.
As of Wednesday, 111 measles cases had been reported in what’s known as upstate South Carolina — an area in the northwest of the state that includes Greenville and Spartanburg.
“We are faced with ongoing transmission that we anticipate will go on for many more weeks,” Dr. Linda Bell, state epidemiologist for the South Carolina Department of Public Health, said during a news briefing Wednesday.
A measles outbreak that began in South Carolina at the start of October is showing no signs of slowing as officials on Tuesday reported 27 new cases since Friday. Those cases bring the outbreak total to 111.
The southern state’s outbreak now rivals outbreaks ongoing in Utah and Arizona, which have tallied 115 and 176 cases, respectively. The outbreaks are threatening to cost the country its measles elimination status, which was earned in 2000 after vaccination efforts stopped the virus from spreading continuously. If the current transmission of the virus isn’t halted by January, the virus will have circulated for 12 consecutive months, marking it once again as an endemic disease in the US.
Health authorities in the United Kingdomconfirmed on December 8, 2025, that they had detected a so-called "recombinant" version of the mpox virus in a male patient.
A virus becomes a recombinant virus when two existing versions of it recombine — by mixing their genetic information — to form a new, hybrid version. This can happen when different types of a virus infect a person at the same time.
The UK's national health security agency, UKHSA, said the recombinant mpox virus was detected in a man who had recently returned to the UK from Asia.
