Fact Check: "Illegal immigrants are causing the latest measles outbreak"

What We Know

The claim that "illegal immigrants are causing the latest measles outbreak" has emerged in the context of recent measles outbreaks in the United States, particularly one associated with a migrant shelter in Chicago. According to a report by the CDC, 57 measles cases were linked to a migrant shelter in Chicago, where many residents were unvaccinated, primarily due to low vaccination rates among migrants from Venezuela, a country experiencing a decline in routine childhood immunization coverage (source-1).

The outbreak was characterized by a rapid spread of the virus in a congregate living situation, where vaccination coverage was notably low. The Chicago Department of Public Health (CDPH) implemented a mass vaccination campaign that successfully increased vaccination rates among shelter residents (source-1).

In addition, a broader measles outbreak has been reported in Texas and New Mexico, with over 250 cases linked to various communities, including some unvaccinated individuals (source-3). However, health officials have stated that they have not been able to pinpoint the source of this outbreak, and there is no direct evidence linking it to illegal immigration (source-7).

Analysis

The evidence surrounding the claim is mixed. The outbreak in Chicago is indeed associated with a migrant shelter where many residents were unvaccinated, which aligns with the assertion that illegal immigrants may be involved in the outbreak. However, it is crucial to note that the outbreak was primarily due to low vaccination rates rather than the mere presence of illegal immigrants. The CDC report emphasizes that the majority of cases were among unvaccinated individuals, not necessarily indicating that the immigrants themselves were the cause of the outbreak (source-1).

Moreover, the broader outbreak in Texas and New Mexico has been reported without a clear link to immigration. Health officials have stated that the source of the outbreak is unknown, and they have not found evidence connecting it to illegal immigration (source-6, source-8). This suggests that while there are instances where unvaccinated migrants have been involved in outbreaks, attributing the outbreaks solely to illegal immigration lacks sufficient evidence.

The sources used in this analysis are credible, primarily from public health institutions like the CDC and reputable news outlets. However, some sources that support the claim may exhibit bias, particularly those that frame the issue within a political context regarding immigration policies (source-6).

Conclusion

The claim that "illegal immigrants are causing the latest measles outbreak" is Partially True. While there is a documented outbreak linked to a migrant shelter in Chicago, the primary driver of the outbreak appears to be low vaccination rates rather than the presence of illegal immigrants per se. Furthermore, the broader outbreaks in Texas and New Mexico have not been directly connected to immigration. Thus, while there are elements of truth in the claim, it oversimplifies a complex public health issue.

Melania became a US citizen July twenty-8th two thousand and 6. Trump wants to end birthright citizenship when his own child is a product of birthright citizenship. We can question a Mexican-American citizen for marrying an undocumented Mexican. Oh yeah, we gotta be able to question when Europeans do the same thing or no. On my mama, think about it.

Fact Check: 11 YR OLD SHOOTS ILLEGALS thanks FOX NEWS for reporting it. BUTTE , MONTANA Shotgun preteen vs. Illegal alien Home Invaders...Two illegal aliens, Ralphel Resindez, 23, and Enrico Garza, 26, probably believed they would easily overpower home-alone 11-year-old Patricia Harrington after her father had left their two-story home. It seems the two crooks never learned two things: they were in Montana and Patricia had been a clay-shooting champion since she was nine.Patricia was in her upstairs room when the two men broke through the front door of the house. She quickly ran to her father's room and grabbed his 12-gauge Mossberg 500 shotgun. Resindez was the first to get up to the second floor only to be the first to catch a near point blank blast of buckshot from the 11-year-old's knee-crouch aim. He suffered fatal wounds to his abdomen and genitals.When Garza ran to the foot of the stairs, he took a blast to the left shoulder and staggered out into the ...street where he bled to death before medical help could arrive. It was found out later that Resindez was armed with a stolen 45-caliber handgun he took from another home invasion robbery. That victim, 50-year-old David 0'Burien, was not so lucky. He died from stab wounds to the chest.Ever wonder why good stuff never makes NBC, CBS, PBS, MSNBC, CNN, or ABC news........? An 11 year old girl, properly trained, defended her home, and herself......against two murderous, illegal immigrants.......and she wins. She is still alive. Now THAT is Gun Control!Thought for the day.... Calling an illegal alien an 'undocumented immigrant' is like calling a drug dealer an 'unlicensed pharmacist.'I like this kind of e-mail!
