At the moment when the debate about the back to school in Minas Gerais in the middle of a pandemic period, Belo Horizonte is still in a dangerous situation in the expansion of the disease and has a high risk of transmission in schools. That was the conclusion of a study coordinated by the infectologist Carlos Starling, member of the Coronavrus Confrontation Committee in the capital of Minas Gerais, based on data released by the State Department of Health (SES-MG). According to the survey, the city has a high rate of community transmission of the virus and there is no guarantee that students would be safe in educational institutions.

To reach a conclusion, the group of researchers added the cases of each municipality in the last 14 days and divided them by the total population. Based on the Centers for Disease Control (CDC), in Atlanta, a rate of COVID-19 considered low if there are less than 20 infected per 100 thousand inhabitants in the same 14 days. The high transmission rate is considered when the number of contaminants is between 50 and 200 per 100 thousand inhabitants. The very high expansion would be when the cases exceed 200 in the same period, per 100 thousand inhabitants.

The scenario experienced by Belo Horizonte is similar to that of 331 other Minas Gerais municipalities, which also have a across high, regardless of the region they are in. These are the cases of Contagem (617 thousand inhabitants), Betim (429.507), Ibirit (155.209), Tefilo Otoni (130.521), Sabar (125.285), Ouro Preto (69.251) Ant (66.834), whose disease expansion rates are still pending. in an alarming situation and for that reason, it is insecure to give the initial kick-off for the reopening of schools.

Even though it is still at risk, Belo Horizonte has been showing stability in the number of cases per 100 thousand inhabitants. The research shows that the average of infected people was 290 per 100 thousand from July 22 to August 4, rose to 311 from August 5 to August 18, but presented new decreases from August 19 to September 1 (206), from 2 of September 15 (170) and September 16 to 29 (162).

“In Belo Horizonte, we have this reduction tendency transmission rate of the disease, which is positive. We have a weighted rate, which is gradually decreasing, which means that schools will be able to safely reopen in the future. Although the numbers are high, the cases in the city are falling ”, emphasizes Carlos Starling.

The survey also shows that 52 mining municipalities (6% of the total) currently have a low transmission rate of COVID-19 and another 163 have a very low rate of expansion. On the other hand, 167 cities (20%) are still experiencing peak disease, with very high rates of contamination, such as Ipatinga (241 thousand inhabitants), Itabira (109 thousand), Muria (99 thousand) and Nova Lima (75 thousand) . These cities have to make a big effort to lower rates and the population follows the rules to have a comfortable situation for returning to school “, says the infectologist.

Stability

The study numbers also show that 401 cities in Minas Gerais (47%) showed a downward trend in cases and, therefore, they would be closer to reopening educational institutions. Another 395 remain on the rise and only 57 (7%) are in a stable situation.

He explains that, due to the different situations in the regions of Minas, less than half of the municipalities could safely reopen schools: “We conclude that only 25% of the municipalities in Minas Gerais would be in an adequate and comfortable situation to start classes. But most are not in a position. And today half of the state is experiencing an increase in cases and the other half has been reducing ”

The study also classified transmission risks by region of Minas. The Southern Triangle and the Northern Triangle would be the most dangerous to return to school, with 74% and 48% of very high risk of transmission in schools, respectively. Then comes the Northwest (39%), the East (25%) and the South (25%). At the bottom, the safest regions for the resumption of the school year would be Jequitinhonha, with 42% very low risk of transmission, and Center-South, with 41%.

Or what or coronavrus

Coronaviruses are a large family of viruses that cause respiratory infections. The new coronavirus agent (COVID-19) was discovered in December 2019 in China. The disease can cause infections with symptoms initially similar to colds or mild flu, but with the risk of getting worse, which can result in death.
