Daniela Hernandez | WSJ – Getting the flu can increase the risk of getting a second infection, including strep throat. WSJ’S Daniela Hernandez explains the science behind that, plus what it means for the rest of the winter and how we can protect ourselves so the tripledemic doesn’t get worse.
Physicians are reporting high numbers of respiratory illnesses like RSV and the flu earlier than the typical winter peak. WSJ’s Brianna Abbott explains what the early surge means for the coming winter months.
Respiratory syncytial virus (RSV) causes infections of the lungs and respiratory tract. It’s so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults.
In adults and older, healthy children, RSV symptoms are mild and typically mimic the common cold. Self-care measures are usually all that’s needed to relieve any discomfort.
RSV can cause severe infection in some people, including babies 12 months and younger (infants), especially premature infants, older adults, people with heart and lung disease, or anyone with a weak immune system (immunocompromised).
More than one million Americans were killed by Covid-19 in just over two years, the CDC reports. But the disease has hit some segments of the U.S. population far more than others. Photo illustration: Todd Johnson
Although intermittent fasting is most widely known as a weight-loss strategy, emerging research suggests that it could have benefits for brain health and cognition. But does it actually work, are there any drawbacks and how long would you have to fast to see benefits?
WSJ’s Daniela Hernandez breaks down what’s known and what’s not about the neuroscience of intermittent fasting.

New high-tech Covid-19 tests promise better and earlier detection of the virus—similar to a PCR test. WSJ’s Joanna Stern (and her mannequin clone) tried out the Detect Covid-19 Test and Cue Health Monitoring System to see how they compare with rapid antigen tests. Photo illustration: Ryan Trefes/ WSJ
Doctors are increasingly turning to monoclonal-antibody drugs to treat high-risk patients who get sick with Covid-19. WSJ takes a look at how the therapies work and why they’re important for saving lives. Illustration: Jacob Reynolds/WSJ
Recent studies have shown that the effectiveness of Covid-19 vaccines is decreasing, though experts say the shots still work well. WSJ explains what the numbers mean and why they don’t tell the full story. Photo illustration: Jacob Reynolds/WSJ
Across the country, states are shelling out incentives ranging from free beer to $1 million lotteries to encourage residents to get their Covid-19 shots. But is the effort to boost vaccination rates working? And is it worth the cost? Photo composite: Adam Falk/The Wall Street Journal
As highly transmissible coronavirus variants sweep across the world, scientists are racing to understand why these new versions of the virus are spreading faster, and what this could mean for vaccine efforts. New research says the key may be the spike protein, which gives the coronavirus its unmistakable shape. Illustration: Nick Collingwood/WSJ
