Few cases of monkeypox have occurred in children during this outbreak, and while the illness is usually mild, it's important for parents to know how to recognize and prevent this virus.

A 2022 study found that survivors of severe COVID-19 infections can develop cognitive problems, such as brain fog or trouble finding words, equivalent to the loss of 10 IQ points or 20 years of aging.

For some people, the effects of the influenza (flu) virus can lead to a heart attack or cardiac arrest (sudden death). These people typically have reduced blood flow to the heart due to atherosclerosis (narrowed arteries). Because the flu can cause blood oxygen levels to drop to dangerously low levels, it can further reduce the supply of oxygen to the heart, causing a heart attack or cardiac arrest. Fortunately, getting an annual flu shot is associated with reduced risks of a heart attack and related cardiac events.

Recent news reports about cases of polio have some parents concerned about the illness. The vaccine is safe and remarkably effective, and widespread vaccination builds herd immunity.

A 2022 study found that women with long COVID showed more symptoms than men, including shortness of breath and fatigue.

Clostridioides difficile, a bacterium that causes severe diarrhea and colon inflammation, is common in hospitalized people. New research suggests that even patients who are not diagnosed with the infection in the hospital can bring it home and expose family members.

More than two years after COVID-19 reached the US, an outbreak of monkeypox is spreading fast outside of Africa. This virus is not new, and it's likely to be less dangerous than COVID, but it's still important to be aware of its symptoms, spread, treatment, and prevention.

The monkeypox outbreak currently traveling around the globe is the largest ever recorded outside of western and central Africa. Controlling this virus demands preventive measures, and one method that has worked to contain previous disease outbreaks may be effective for monkeypox as well.

The bacteria C. diff is responsible for half a million infections each year in the US. Many infections happen when people are hospitalized, but a recent report indicated that people can be infected without ever being hospitalized.

Thanks to vaccination, the US has been polio-free since 1979, and the spread of this disease has been interrupted in most countries. But worldwide eradication of polio has been elusive, and traces of the virus were recently found in wastewater in London.
