Health Center Testing for SARS-CoV-2 During the COVID-19 Pandemic - United States, June 5-October 2, 2020
MMWR. Morbidity and Mortality Weekly Report
|December 17, 2020
Summary
Racial and ethnic minority populations face higher COVID-19 risks. Health centers provide crucial testing and care, with Hispanic/Latino individuals showing disproportionately high positive test results.
Area of Science:
- Public Health
- Epidemiology
- Health Disparities
Background:
- COVID-19 disproportionately affects racial and ethnic minority populations due to historical social inequities.
- Health Resources and Services Administration (HRSA) health centers serve millions, including many from minority groups, in underserved areas.
- These centers are vital for providing COVID-19 prevention, testing, and follow-up care to at-risk communities.
Purpose of the Study:
- To assess the capacity of HRSA-funded health centers to reach and test racial and ethnic minority groups at increased risk for COVID-19.
- To analyze COVID-19 testing and positivity rates among different racial and ethnic groups served by health centers.
Main Methods:
- Analysis of voluntary HRSA Health Center COVID-19 Survey data from June 5 to October 2, 2020.
- Examination of testing and positive SARS-CoV-2 test results by race/ethnicity and state of residence for over 2.5 million individuals with known race/ethnicity.
Main Results:
- Among tested individuals with known race/ethnicity, 36% were Hispanic, 38% White, and 20% Black.
- Among those with positive test results, 56% were Hispanic, 24% White, and 15% Black.
- Hispanic individuals showed a higher proportion of positive COVID-19 tests compared to their representation in the tested population.
Conclusions:
- Health centers are critical in providing COVID-19 testing and care to vulnerable populations.
- Improving health center reach to high-risk groups can help reduce COVID-19 transmission through case identification and contact tracing.
- Enhanced coordination between public health departments and health centers is essential for equitable access to testing and follow-up care.

Sputum Studies II: Culture and Sensitivity
867
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

Single Nucleotide Polymorphisms-SNPs
17.4K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
