Reported COVID-19 cases in Arizona dropped 30% last week, and the percentage of tests returning positive declined too, a weekly state update says.
Percent positivity, which refers to the percentage of COVID-19 diagnostic tests that are positive, varies somewhat based on how it's measured. It was high in the winter months, a sign of more community spread. Then it was much lower but began climbing upward in April.
A positivity rate of 5% or less is considered a good benchmark that the disease's spread is under control. Arizonans ages 6 months and older are eligible for the Pfizer-BioNTech vaccine, while the Moderna vaccine is approved for children ages 6 months to 5 years and people 18 and older. The CDC has recommended the Johnson & Johnson vaccine on a more limited basis for people 18 and older. Many individuals are eligible for booster doses, too.

A cross-country analysis of macroeconomic responses to COVID-19 pandemic using Twitter sentimentsThe COVID-19 pandemic has had a devastating impact on the global economy. In this paper, we use the Phillips curve to compare and analyze the macroeconomics of three different countries with distinct income levels, namely, lower-middle (Nigeria), upper-middle (South Africa), and high (Canada) income. We aim to (1) find macroeconomic changes in the three countries during the pandemic compared to pre-pandemic time, (2) compare the countries in terms of response to the COVID-19 economic crisis, and (3) compare their expected economic reaction to the COVID-19 pandemic in the near future. An advantage to our work is that we analyze macroeconomics on a monthly basis to capture the shocks and rapid changes caused by on and off rounds of lockdowns. We use the volume and social sentiments of the Twitter data to approximate the macroeconomic statistics. We apply four different machine learning algorithms to estimate the unemployment rate of South Africa and Nigeria on monthly basis. The results show that at the beginning of the pandemic the unemployment rate increased for all the three countries. However, Canada was able to control and reduce the unemployment rate during the COVID-19 pandemic. Nonetheless, in line with the Phillips curve short-run, the inflation rate of Canada increased to a level that has never occurred in more than fifteen years. Nigeria and South Africa have not been able to control the unemployment rate and did not return to the pre-COVID-19 level. Yet, the inflation rate has increased in both countries. The inflation rate is still comparable to the pre-COVID-19 level in South Africa, but based on the Phillips curve short-run, it will increase further, if the unemployment rate decreases. Unfortunately, Nigeria is experiencing a horrible stagflation and a wild increase in both unemployment and inflation rates. This shows how vulnerable lower-middle-income countries could be to lockdowns and economic restrictions. In the near future, the main concern for al
