Measles, a highly contagious respiratory virus with the potential to cause severe complications, hospitalization, and death, was declared eliminated from the United States in 2000; however, with ongoing global transmission, infections in the United States still occur. On March 7, 2024, the Chicago Department of Public Health (CDPH) confirmed a case of measles in a male aged 1 year residing in a temporary shelter for migrants in Chicago. Given the congregate nature of the setting, high transmissibility of measles, and low measles vaccination coverage among shelter residents, measles virus had the potential to spread rapidly among approximately 2,100 presumed exposed shelter residents. CDPH immediately instituted outbreak investigation and response activities in collaboration with state and local health departments, health care facilities, city agencies, and shelters. On March 8, CDPH implemented active case-finding and coordinated a mass vaccination campaign at the affected shelter (shelter A), including vaccinating 882 residents and verifying previous vaccination for 784 residents over 3 days. These activities resulted in 93% measles vaccination coverage (defined as receipt of ≥1 recorded measles vaccine dose) by March 11. By May 13, a total of 57 confirmed measles cases associated with residing in or having contact with persons from shelter A had been reported. Most cases (41; 72%) were among persons who did not have documentation of measles vaccination and were considered unvaccinated. In addition, 16 cases of measles occurred among persons who had received ≥1 measles vaccine dose ≥21 days before first known exposure. This outbreak underscores the need to ensure high vaccination coverage among communities residing in congregate settings., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Since the beginning of the Zika virus epidemic, the Brazilian Ministry of Health has reported over 2000 confirmed cases of microcephaly associated with Zika virus in Brazil, with the cases concentrated in the northeast states. The Zika epidemic reopened a debate in Brazil that has played out in the national newspapers about expanding the abortion law to provide autonomy and legal protection to women. The argument for expanding the abortion law to include microcephaly secondary to Zika virus infection called for autonomy for women and, more broadly, protection of reproductive rights. The argument against expanding the current abortion law was separated into two main moral veins: those citing eugenics and those citing religious beliefs. However, the debate on abortion in the case of microcephaly accomplished more than giving a voice to two different viewpoints; it exposed health disparities that exist in Brazil, which were magnified by Zika virus, and reopened the political arena for discussion of the abortion law.

Introduction In 2015, there was an outbreak of Zika virus in Brazil that spread throughout the Americas. The association of Zika virus with birth defects in infants born to infected pregnant women created concern for women of childbearing age. Social media is an important platform for health promotion, communication, and education on preventative methods during Zika virus outbreaks. Methods We evaluated the utility of social media on providing information regarding Zika virus. Facebook, Instagram, Twitter, and YouTube were utilized for our study. A search of the term "#Zikavirus" on Twitter and Instagram, and "Zika virus" on Facebook and YouTube was performed. The first 50 search results were analyzed from each source. Only English, Spanish, or Portuguese results were included. Results were categorized into three groups: "Useful", "Not Useful", or "Misleading". Results Search was conducted on December 17th, 2016, with 185 results. Forty (21.6%) were from Facebook, 50 (27%) from Twitter, 48 (25.9%) from YouTube, and 47 (25.4%) from Instagram. A total of 104 (56.22%) results were "Useful", 67 (36.2%) "Not Useful", and 14 (7.5%) were "Misleading". There were significantly more "Useful" results compared to "Not Useful" and "Misleading" results (Fisher's exact: p < 0.0001). Conclusion Social media is a useful resource for providing relevant information on Zika virus. Young women can utilize social media for Zika virus information. The role of social media in public health should be further investigated and established. Patient education interventions should focus on social media impact on behavior modification and education of public to recognize useful information., Competing Interests: The authors have declared that no competing interests exist.
