Outcomes of Pregnancies with Laboratory Evidence of Possible Zika Virus Infection in the United States

CDC

 

Outcomes for Completed Pregnancies in the United States and District of Columbia, 2016-2017

Completed pregnancies with or without birth defects:  1,047

Includes aggregated data reported to the US Zika Pregnancy Registry*

Liveborn infants with birth defects*:  43

Pregnancy losses with birth defects**:  5

*As of February 7, 2017

What these numbers show

  • The number of completed pregnancies with or without birth defects include those that ended in a live birth, miscarriage, stillbirth, or termination.
  • The number of liveborn infants and pregnancy losses with birth defects include those among completed pregnancies with laboratory evidence of possible Zika virus infection that have been reported to the US Zika Pregnancy Registry.
  • These numbers rely on reporting to the US Zika Pregnancy Registry and may increase or decrease as new cases are added or information on existing cases is clarified. For example, CDC cannot report the number of completed pregnancies with or without poor pregnancy outcomes that have not yet been reported to the US Zika Pregnancy Registry.
  • The number of liveborn infants and pregnancy losses with birth defects are combined for the 50 US states, and the District of Columbia. CDC is not reporting individual state, tribal, territorial or jurisdictional level data to protect the privacy of the women and children affected by Zika. CDC is using a consistent case inclusion criteria to monitor brain abnormalities and other adverse pregnancy outcomes potentially related to Zika virus infection during pregnancy in the US states and territories. Puerto Rico is not using the same inclusion criteria; CDC is not reporting numbers for adverse pregnancy outcomes in the territories at this time.
  • Birth defects reported include those that have been detected in infants infected with Zika before, during, or shortly after birth, including microcephaly, calcium deposits in the brain indicating possible brain damage, excess fluid in the brain cavities and surrounding the brain, absent or poorly formed brain structures, abnormal eye development, or other problems resulting from damage to brain that affects nerves, muscles and bones, such as clubfoot or inflexible joints, and confirmed hearing loss.

What these new numbers do not show

  • These numbers are not real time estimates. They reflect the outcomes of pregnancies with any laboratory evidence of possible Zika virus infection reported to the US Zika Pregnancy Registry as of 12 noon Tuesday the week prior. Additionally, there may be delays in reporting of pregnancy outcomes from the jurisdictions.
  • Although these outcomes occurred in pregnancies with laboratory evidence of possible Zika virus infection, we do not know whether they were caused by Zika virus infection or other factors.

Where do these numbers come from?

  • These data reflect pregnancies reported to the US Zika Pregnancy Registry(https://www.cdc.gov/zika/hc-providers/registry.html). CDC, in collaboration with state, local, tribal and territorial health departments, established this system for comprehensive monitoring of pregnancy and infant outcomes following Zika virus infection.
  • The data collected through this system will be used to update recommendations for clinical care, to plan for services and support for pregnant women and families affected by Zika virus, and to improve prevention of Zika virus infection during pregnancy.

2016-2017 Influenza Season Week 6 ending February 11, 2017

CDC

During week 6 (February 5-11, 2017), influenza activity increased in the United States.

  • Viral Surveillance: The most frequently identified influenza virus subtype reported by public health laboratories during week 6 was influenza A (H3). The percentage of respiratory specimens testing positive for influenza in clinical laboratories increased.
  • Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was above the system-specific epidemic threshold in the National Center for Health Statistics (NCHS) Mortality Surveillance System.
  • Influenza-associated Pediatric Deaths: Nine influenza-associated pediatric deaths were reported.
  • Influenza-associated Hospitalizations:A cumulative rate for the season of 29.4 laboratory-confirmed influenza-associated hospitalizations per 100,000 population was reported.
  • Outpatient Illness Surveillance:The proportion of outpatient visits for influenza-like illness (ILI) was 5.2%, which is above the national baseline of 2.2%. All 10 regions reported ILI at or above their region-specific baseline levels. New York City and 28 states experienced high ILI activity; Puerto Rico and seven states experienced moderate ILI activity; five states experienced low ILI activity; nine states experienced minimal ILI activity; and the District of Columbia had insufficient data.
  • Geographic Spread of Influenza: The geographic spread of influenza in Puerto Rico and 46 states was reported as widespread; Guam and four states reported regional activity; the District of Columbia reported local activity; and the U.S. Virgin Islands reported sporadic activity.

Abstract

The proportion of US food that is imported is increasing; most seafood and half of fruits are imported. We identified a small but increasing number of foodborne disease outbreaks associated with imported foods, most commonly fish and produce. New outbreak investigation tools and federal regulatory authority are key to maintaining food safety.

Approximately 19% of food consumed in the United States is imported, including ≈97% of fish and shellfish, ≈50% of fresh fruits, and ≈20% of fresh vegetables (1). The proportion of food that is imported has increased steadily over the past 20 years because of changing consumer demand for a wider selection of food products and increasing demand for produce items year round (1).

The Centers for Disease Control and Prevention (CDC) defines a foodborne disease outbreak as the occurrence of >2 persons with a similar illness resulting from ingestion of a common food (2). Local, state, and territorial health departments report foodborne disease outbreaks to CDC through the Foodborne Disease Outbreak Surveillance System. The information collected for each outbreak includes etiology (confirmed or suspected on the basis of predefined criteria) (2), year, month, state, implicated food, and number of illnesses, hospitalizations, and deaths. Information is also collected on where implicated food originated. During 1973–1997, this information was reported anecdotally in the report’s comments section. During 1998–2008, “contaminated food imported into U.S.” was included as a location where food was prepared. Since 2009, the form has included a variable to indicate whether an implicated food was imported into the United States and the country of origin.

The Study

We reviewed outbreak reports to identify outbreaks associated with an imported food from the inception of the surveillance system in 1973 through 2014, the most recent year for which data were available. We obtained additional data for some outbreaks (e.g., country of origin) from the US Food and Drug Administration (FDA) and the US Department of Agriculture Food Safety and Inspection Service.

We categorized implicated foods by using the schema developed by the Interagency Food Safety Analytics Collaboration (3). We grouped countries using the United Nations Statistics Division classification (4). We conducted a descriptive analysis of the number of outbreaks over time, by food category, and by region of origin.

Reporting practices changed over time; 1973–1997, imported foods anecdotally noted in report…

During 1996–2014, a total of 195 outbreak investigations implicated an imported food, resulting in 10,685 illnesses, 1,017 hospitalizations, and 19 deaths. Outbreaks associated with imported foods represented an increasing proportion of all foodborne disease outbreaks where a food was implicated and reported (1% during 1996–2000 vs. 5% during 2009–2014). The number of outbreaks associated with an imported food increased from an average of 3 per year during 1996–2000 to an average of 18 per year during 2009–2014 (Figure).

The most common agents reported in outbreaks associated with imported foods were scombroid toxin and Salmonella; most illnesses were associated with Salmonella and Cyclospora (Table(https://wwwnc.cdc.gov/eid/article/23/3/16-1462-t1)). Aquatic animals were responsible for 55% of outbreaks and 11% of outbreak-associated illnesses. Produce was responsible for 33% of outbreaks and 84% of outbreak-associated illnesses. Outbreaks attributed to produce had a median of 40 illnesses compared with a median of 3 in outbreaks attributed to aquatic animals. All but 1 of the outbreaks caused by scombroid toxin was associated with fish. Most of the Salmonella outbreaks (77%) were associated with produce, including fruits (n = 14), seeded vegetables (n = 10), sprouts (n = 6), nuts and seeds (n = 5), spices (n = 4), and herbs (n = 1).

Information was available on the region of origin for 177 (91%) outbreaks. Latin America and the Caribbean was the most common region implicated, followed by Asia (Technical Appendix(https://wwwnc.cdc.gov/eid/article/23/3/16-1462-techapp1.xlsx)). Thirty-one countries were implicated; Mexico was most frequently implicated (42 outbreaks). Other countries associated with >10 outbreaks were Indonesia (n = 17) and Canada (n = 11). Fish and shellfish originated from all regions except Europe but were most commonly imported from Asia (65% of outbreaks associated with fish or shellfish). Produce originated from all regions but was most commonly imported from Latin America and the Caribbean (64% of outbreaks associated with produce). All but 1 outbreak associated with dairy products involved products imported from Latin America and the Caribbean.

Outbreaks in this analysis were reported from 31 states, most commonly California (n = 30), Florida (n = 25), and New York (n = 16). Forty-three outbreaks (22%) were multistate outbreaks.

Conclusions

The number of reported outbreaks associated with imported foods, although small, has increased as an absolute number and in proportion to the total number of outbreaks in which the implicated food was identified and reported. Although many types of imported foods were associated with outbreaks, fish and produce were most common. These findings are consistent with overall trends in food importation (5).

Many outbreaks, particularly outbreaks involving produce, were associated with foods imported from countries in Latin America and the Caribbean. Because of their proximity, these countries are major sources of perishable items such as fresh fruits and vegetables; Mexico is the source of about one quarter of the total value of fruit and nut imports and 45%–50% of vegetable imports, followed by Chile and Costa Rica. Similarly, our finding that many outbreaks were associated with fish from Asia is consistent with data on the sources of fish imports (6).

One quarter of the outbreaks were multistate, reflecting the wide distribution of many imported foods. Systems like PulseNet have helped to improve detection and investigation of multistate outbreaks, resulting in an increased number of multistate outbreaks (7,8). The increasing number of outbreaks involving globally distributed foods underscores the need to strengthen regional and global networks for outbreak detection and information sharing. The importance of having standard protocols for molecular characterization of isolates and systems for rapid traceability of implicated foods to their source was illustrated during the investigation of a listeriosis outbreak linked to Italian cheese imported into the United States in 2012 (9). Newer tools like whole genome sequencing can also help to generate hypothetical transmission networks and in some instances facilitate traceback of foods to their origin (10). Moreover, new tools that aid visualization of supplier networks facilitate the investigation of outbreaks involving the increasingly complex global economy (11).

Nearly all of the outbreaks involved foods under FDA jurisdiction. Only a small proportion of FDA-regulated foods are inspected upon entry into the United States. New rules under the Food Safety Modernization Act of 2011, including the Preventive Controls Rule for Human Food, Produce Safety Rule, Foreign Supplier Verification Program, and Accreditation of Third Party Auditors, will help to strengthen the safety of imported foods by granting FDA enhanced authorities to require that imported foods meet the same safety standards as foods produced domestically (12).

Although data collection has improved in recent years, these findings might underestimate the number of outbreaks associated with imported foods because the origin of only a small proportion of foods causing outbreaks is reported. Similarly, because of how data are collected and reported, the relative safety of imported and domestically produced foods cannot be compared. Because of changes in surveillance and changing import patterns, changes over time should be interpreted cautiously.

Our findings reflect current patterns in food imports and provide information to help guide future outbreak investigations. Prevention focused on the most common imported foods causing outbreaks, produce and seafood, could help prevent outbreaks. Efforts to improve the safety of the food supply can include strengthening reporting by gathering better data on the origin of implicated food items, including whether imported and from what country.

A surge of H7N9 avian flu activity in China that began in December shows no sign of tailing off, with 61 new cases reported last week, pushing the mainland’s total to at least 419 cases—100 more than the previous high reported during the second wave in 2013-14.

“According to the Chinese Center for Disease Control and Prevention, about 90 per cent of the patients in the Mainland reported exposure to live poultry, mostly with exposure to live poultry markets (LPMs). There was also an increase in environmental contamination with H7N9 virus as reflected by the positive rate of environmental samples collected from LPMs or other live poultry-related environments in affected provinces,” the spokesman said.”
