ihscovid19The Indian Health Service has updated its coronavirus data, showing results through September 12, 2021.

According to the data, 238,668 tests have returned positive for COVID-19, the disease caused by the coronavirus. That represents an increase of nearly 1.2 percent from the 235,901 cases previously reported on September 8.

Altogether, 2,904,048 coronavirus tests have been administered within the IHS, the results show. That represents an increase of 0.9 percent from four days prior.

Since mid-October of 2020, the IHS has been providing additional information about the spread of the coronavirus within the system. The cumulative percent positive column shows the historical COVID-19 infection rate, meaning the number of tests that have returned positive since the onset of the pandemic.

Based on the cumulative percent positive, the highest rates have been seen in five areas. Two of them include the state of Arizona, indicating a disproportionate toll of COVID-19 in the state:

The 7-day rolling average positivity column offers a more contemporary look at the impact of the coronavirus. The data shows where COVID-19 cases have been increasing recently.

Based on the 7-day rolling average positivity, 11 out of 12 IHS areas are seeing higher COVID-19 rates. The 📈 symbol indicates the regions in which positivity rates are on the rise:

Notably, the 7-day rolling average positivity for the Alaska Area has steadily grown in recent weeks. The region recorded its highest-ever rate with the release of data on September 12, beating records set on September 8. Throughout most of the pandemic, the Alaska Area had seen the lowest rate of COVID-19 cases within the IHS.

Overall, 8.8 percent of IHS tests have been positive since the onset of the pandemic, the data shows. Meanwhile, the 7-day average stands at 11.1 percent following a long period of far lower rates in the spring of 2021.

The data, however, is incomplete. While 100 percent of facilities run directly by the IHS are reporting data, only 33 percent of tribally managed facilities and 44 percent of urban Indian organizations are doing the same, the agency has told Indianz.Com.

Beginning June 7, the IHS began updating its coronavirus data on a weekly basis. But as the number of COVID-19 cases grows again, the agency is releasing results on Mondays and Thursdays. During the height of the pandemic throughout 2020 and the first half of 2021, results were provided every day.
