Outbreaks of SARS-CoV-2 Infections in Nursing Homes during Periods of Delta and Omicron Predominance, United States, July 2021-March 2022.

SARS-CoV-2 infections among vaccinated nursing home residents increased after the Omicron variant emerged. Data on booster dose effectiveness in this population are limited. During July 2021-March 2022, nursing home outbreaks in 11 US jurisdictions involving >3 infections within 14 days among residents who had received at least the primary COVID-19 vaccine(s) were monitored.

Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) outbreaks in nursing homes involving residents who had completed a primary coronavirus disease 2019 (COVID-19) vaccine series-13 US jurisdictions, July-November 2021.

Among nursing home outbreaks of coronavirus disease 2019 (COVID-19) with ≥3 breakthrough infections when the predominant severe acute respiratory coronavirus virus 2 (SARS-CoV-2) variant circulating was the SARS-CoV-2 δ (delta) variant, fully vaccinated residents were 28% less likely to be infected than were unvaccinated residents. Once infected, they had approximately half the risk for all-cause hospitalization and all-cause death compared with unvaccinated infected residents.

An overview from the 2019 Swine Fever Exercise for Agriculture Response in Iowa.

Iowa leads the United States in pork production, housing approximately one-third of the country's swine population. This puts Iowa at great economic risk if an outbreak of African swine fever, a disease that limits international trade opportunities, were to occur anywhere in the United States. To hone emergency response plans to combat an outbreak, the Iowa Department of Agriculture and Land Stewardship in September 2019 participated in a 4-day exercise with representatives from the other 13 top pork-producing states.

Domestically Acquired Virus Causing Hemophagocytic Lymphohistiocytosis-Washington, DC, 2018.

(SEOV) infections, uncommonly reported in the United States, often result in mild illness. We report a case of hemophagocytic lymphohistiocytosis secondary to SEOV infection that was domestically acquired in Washington, DC.

Enhanced One Health Surveillance during the 58th Presidential Inauguration-District of Columbia, January 2017.

Objective: In January 2017, Washington, DC, hosted the 58th United States presidential inauguration. The DC Department of Health leveraged multiple health surveillance approaches, including syndromic surveillance (human and animal) and medical aid station-based patient tracking, to detect disease and injury associated with this mass gathering.

Methods: Patient data were collected from a regional syndromic surveillance system, medical aid stations, and an internet-based emergency department reporting system.

Assessing rabies knowledge gaps in human and animal healthcare professionals practicing in Washington, DC-A one health approach.

Once a person is exposed to the rabies virus, it is universally fatal unless postexposure prophylaxis (PEP) is administered promptly. In the United States, determining whether PEP recommeded is often a collaborative effort where health departments work with both animal and human healthcare professionals to enact animal quarantines (or rabies testing), recommending PEP when appropriate. A failure in the knowledge base of either profession can result in incorrect PEP recommendations and an increased risk of adverse outcomes.

Investigation of Salmonella Enteritidis Outbreak Associated with Truffle Oil - District of Columbia, 2015.

On September 8, 2015, the District of Columbia Department of Health (DCDOH) received a call from a person who reported experiencing gastrointestinal illness after eating at a District of Columbia (DC) restaurant with multiple locations throughout the United States (restaurant A). Later the same day, a local emergency department notified DCDOH to report four persons with gastrointestinal illness, all of whom had eaten at restaurant A during August 30-September 5. Two patients had laboratory-confirmed Salmonella group D by stool culture.

Expanding veterinary biosurveillance in Washington, DC: The creation and utilization of an electronic-based online veterinary surveillance system.

Objectives: To enhance the early detection of emerging infectious diseases and bioterrorism events using companion animal-based surveillance.

Methods: Washington, DC, small animal veterinary facilities (n=17) were surveyed to determine interest in conducting infectious disease surveillance. Using these results, an electronic-based online reporting system was developed and launched in August 2015 to monitor rates of canine influenza, canine leptospirosis, antibiotic resistant infections, canine parvovirus, and syndromic disease trends.

Zika Virus Infection with Prolonged Maternal Viremia and Fetal Brain Abnormalities.

The current outbreak of Zika virus (ZIKV) infection has been associated with an apparent increased risk of congenital microcephaly. We describe a case of a pregnant woman and her fetus infected with ZIKV during the 11th gestational week. The fetal head circumference decreased from the 47th percentile to the 24th percentile between 16 and 20 weeks of gestation.

Zika Virus Infection Among U.S. Pregnant Travelers - August 2015-February 2016.

After reports of microcephaly and other adverse pregnancy outcomes in infants of mothers infected with Zika virus during pregnancy, CDC issued a travel alert on January 15, 2016, advising pregnant women to consider postponing travel to areas with active transmission of Zika virus. On January 19, CDC released interim guidelines for U.S.
