Why Should You Care About Malaria?

In June and July, eight locally acquired cases of malaria were diagnosed in the U.S.—seven in Florida and one at the southern tip of Texas. Cases in the two states appear to be unrelated, and all patients are recovering. In both geographic areas, it’s likely that malaria in people with travel-related cases was transmitted by local (U.S.) mosquitoes to the people who developed the locally acquired cases.

Malaria was endemic in this country until the early 1950s, when mosquito control programs and public health campaigns brought the disease under control. Since that time, virtually all cases in the U.S—now at almost 2000 per year—have been travel related.

Malaria transmission.

Malaria is caused by several species of the Plasmodium parasite, transmitted by the bite of a female Anopheles mosquito infected by the parasite. In less than one percent of cases, transmission occurs congenitally or via transfusion, organ transplant, or unsafe needle sharing.

Why it matters.

Respiratory Illness Surge: Differentiating and Treating RSV, COVID, and Flu in Children

Concern about a respiratory ‘triple-demic.’

Electron micrograph image of respiratory syncytial virus (RSV)/Image source: CDC

Take a walk through many of the country’s pediatric emergency departments (EDs) and inpatient units right now and you will be greeted with the sounds of pinging monitors, suction, and coughing as “respiratory season” settles in.

This will be the first fall and winter that many young children have been back at schools and day cares, largely unmasked, in nearly three years. While respiratory syncytial virus (RSV) and influenza are yearly problems in pediatrics, an unseasonably early and severe surge in RSV is causing an unprecedented number of hospital admissions that is already straining many health systems.

Public health officials are already warning of a “triple-demic” this year as the current RSV surge coalesces with expected rises in influenza and COVID cases. This, of course, does not include the dozens of other respiratory viruses that affect children each winter, including the atypically severe cases of rhinoviruses/enteroviruses and parainfluenza that have already been reported this year.

RSV, influenza, COVID have subtly different symptoms.

While RSV, COVID, and influenza are all viral infections that cause acute respiratory symptoms, they can present with subtly different symptoms. The […]

Message from a Concerned School Nurse

Robin Cogan

In case you have not seen the new Centers for Disease Control and Prevention (CDC) guidelines for schools, published on August 11, 2022, here they are: Operational Guidance for K-12 Schools and Early Care and Education Programs to Support Safe In-Person Learning.

Key changes in CDC guidance for schools.

The CDC has chosen the path of least resistance as schools are about to reopen or are in their first few weeks of the new school year. Although the word “prevention” is included in the CDC’s name, this central goal seems to have been removed from these guidelines, including crucial pieces of the mitigation strategies that in the past prevented the school-level spread of the virus:

Poliovirus: Still a Threat

Last month, an unvaccinated 20-year-old in Rockland County, New York, was diagnosed with paralytic polio. He had not traveled in the previous month; he was infected by an (unknown) individual who had travelled and acquired the infection abroad.

According to the CDC, poliovirus was also found in wastewater from Rockland and a neighboring county—coincidentally sampled in May, June, and July as part of SARS-CoV-2 surveillance—and some of the positive samples were genetically linked to virus from the patient. This reflects ongoing community transmission and ongoing risk to unvaccinated residents. Because most poliovirus infections are […]

The Monkeypox Vaccine: What Nurses Need to Know

In the current monkeypox outbreak, the pandemic-strained U.S. public health system is once again faced with a major threat. This time, a vaccine is already available, but only in limited quantities. Here’s what nurses need to know. It will remain important to keep up with new developments as they occur.

The Jynneos vaccine

Jynneos is a live but nonreplicating vaccine for the prevention of both monkeypox and smallpox. It is made from vaccinia virus, a less virulent relative of these two viruses. The vaccine is given subcutaneously in two separate doses administered at least 28 days apart, and a person is considered fully vaccinated two weeks after the second dose.

The most common vaccine side effects are pain, redness, induration, swelling, or itching at the vaccination site. (People with HIV infection or atopic dermatitis do not seem to experience additional or more severe side […]
