Arquivo CDC: em 2016, 31.944 casos locais de Zika e 45 funcionários em Porto Rico

On September 7, 2026, with the most dense contemporary federal health peg in CDC and HRSA, this table deliberately opens the CDC institutional archive —archive.cdc.gov— for the 2016 account of the National Center for Emerging and Zoonotic Infectious Diseases (NCEZID). The archive portal itself warns that the content is historical, no longer updated, may be outdated, and links may not work. This note does not pretend that on September 7, 2026, CDC reactivated a Zika emergency operations center. The date in the date field is the day assigned on the magazine's calendar; the date of the events is 2016, and it is named as such.

In the November 2016 report, NCEZID wrote that, as of November 29, 98 CDC employees were deployed for the Zika response and 982 had completed deployments. “A total of 45 CDC employees continued to support the response in Puerto Rico, where 31,944 locally acquired cases had been reported as of November 23.” That figure—31,944 locally acquired cases—is the quantitative anchor of the archived page. It is not the total number of suspected cases for the entire epidemic, nor the total laboratory-confirmed infections for the whole year; it is the count that NCEZID cited at that date.

The same report notes that on November 11, the MMWR "Incidence of Zika Virus Disease by Age and Sex – Puerto Rico, November 1, 2015–October 20, 2016" was published. According to NCEZID, among more than 28,200 non-pregnant people with laboratory-confirmed Zika in Puerto Rico, infection was highest among women aged 20 to 49. CDC also then updated the Guidance for US Laboratories Testing for Zika Virus Infection and published an infection control guide for healthcare workers, emphasizing standard precautions.

The file places Puerto Rico at the center of the 2016 federal concern: 'We are especially concerned about Puerto Rico, where the highest number of locally transmitted Zika virus disease cases in the US territories has been reported.' NCEZID describes the partnership with the Department of Health to protect pregnant women, including prevention kits and vector control in their homes. It mentions an estimate of 138,000 women of reproductive age in Puerto Rico who did not want to become pregnant and were not using contraception, and it argues that removing barriers to contraception could reduce unintended pregnancies and, thereby, adverse outcomes associated with Zika. That is the prose of 2016; it is not a 2026 census.

On November 18, 2016, the file notes, the WHO changed the classification of Zika and its consequences from a Public Health Emergency of International Concern to a lasting public health challenge that required intense action and dedicated resources. That shift — from international emergency to sustained program — is the institutional background for why, a decade later, the CDC and HRSA continue to publish AGO trap assessments, home visiting awards, and dengue surveillance: the archipelago of arboviruses cannot be closed with a statement.

Why read the file on September 7, 2026? Because the 2024 dengue epidemic —6,291 confirmed cases, 11 deaths, local emergency in March 2024, according to the February 2025 MMWR— reopened the argument that post-Zika cross-immunity and the COVID gap explain the 11-year hiatus without a major dengue outbreak. The 2016 file does not 'prove' the 2024 outbreak; it does document the human scale and federal staff that the Island has already absorbed once. 45 CDC employees on the Island and 31,944 local cases are magnitudes that a light press count usually rounds incorrectly.

The money typology on this archived page is for personnel deployment, not for a grant line-item. NCEZID does not publish here a total of dollars spent in Puerto Rico in 2016. HRSA, on another 2016 URL, did list awards of $250,000 to health centers for Zika; that is another note, another document. Mixing the NCEZID count with the $5 million from HHS/HRSA to centers, or with the $39 million announced later for territories, would be adding apples from different baskets.

In summary: on September 7, 2026, this magazine rereads, with an honest date, the CDC file from 2016. 31,944 local cases as of November 23; 45 CDC employees still in Puerto Rico; more than 28,200 non-pregnant individuals with positive laboratory results and a peak in women aged 20–49. The material is historical. The vector risk is not.
