Coronavirus: watch out for air conditioning during the heatwave

The number of new cases of Covid-19 per 100,000 inhabitants is on the rise, as is the average number of infections and hospitalizations … Nevertheless, the reproduction rate of the virus has fallen below 1.

The average number of coronavirus infections rose to 535.4 per day between July 26 and August 1, according to Sciensano. This represents an increase of 58% from the previous week. There have been 3,748 new cases in the past seven days. On Saturday, the day we have complete information, there were 288 people diagnosed positive. The number of infections in Belgium now stands at 70,648, against 70,314 on Tuesday.

The name of new cases of Covid-19 per 100,000 inhabitants continues the same upward trend. For the period spanning two weeks, and until August 1 inclusive, 53.2 cases were identified (against 51.2 on Tuesday), i.e. an increase of 200% week to week.

The number of hospital admissions is now 22.7 per day (22 Tuesday), a small decrease of 4%. There are currently 265 people hospitalized, including 63 in intensive care.
Sciensano also reports an average of 2.4 deaths per day. Since the start of the epidemic, 9,852 people have lost their lives as a result of Covid-19.

The reproduction rate of the virus, on the other hand, passed again, this Tuesday, under the 1 bar, to 0,99. This means that a person carrying the virus will infect 0.99 another person. The difference is symbolic, of course, but the drop in this rate, which has been moving just above 1 for several days, in the current context of propagation, is a good signal. This is the reason for the establishment of reduced social bubble system to five people: less contact, less contamination …

The positivity rate

The positivity rate (number of tests returned positive compared to tests performed) is currently 2.7%. However, it rises to 5.3% in Antwerp, 3.7% in Brussels and 3.4% in Liège. As to whether we are already seeing an effect of the new measures, there is still an increase in Antwerp but a little less important, we have the impression that it is slowing down. For the rest of the country, the increase rest important, especially at Brussels and to Liège.

This increase is however “not at all comparable” to that observed in months of March and April, emphasizes Frédérique Jacobs. But the number of people who have tested positive is worrying. “If we do not respect the measures in progress, we risk reaching a second wave.”

Watch out for air conditioning

Of very hot days are announced. Remember that the main mode of contamination of the virus is through droplets when you cough, talk or sneeze. These contaminations are possible when we find ourselves less than 1.50m away. One can also be contaminated by contact of the hands on surfaces when they are then worn on the mucous membranes.

“The pedestal fan should be used exclusively in your home, not outdoors.”

Frederique Jacobs

Interfederal spokesperson for the crisis center

For the moment, we cannot exclude a form of aerosol transmission, the virus can float in the air in very fine particles for a longer time and a longer distance, but this mode of transmission is still under discussion, it seems not very important. It can take place in poorly ventilated rooms when talking loudly, singing or shouting. These rooms must therefore be ventilated naturally (windows and doors open).

Regarding pedestal fan, the crisis center recommends using it exclusively in your home with people who are not known to have contracted the virus.

The air conditioning system could him on the contrary reduce the risk of contamination because the air is more often renewed, provided that the air costs outside is blown so as not to recirculate the same air and therefore increase the risk of contamination.

Color code point

On June 15, the European Union (EU) reopened its borders with one condition: setting up an effective international system for monitoring contacts. This condition is not always fulfilled, the CNS decided a color code by region with associated security measures.

When the area is green, there is a limited spread of the virus (less than 20 cases per 100,000 inhabitants over two weeks). A zone orange sees increased spread (between 20 and 100 cases) and an area rouge beyond 100 cases per 100,000 inhabitants. This color code also reflects the upward and downward trends of these numbers.

Remember also that in green areas, free movement without more conditions is allowed. On the other hand, it is not recommended to go to the orange zones, and it is recommended to be tested and to observe a quarantine of two weeks on return to Belgium. It is not allowed to go to the red zones and the test and quarantine are mandatory on return.

The evaluation unit Celeval assess the situation in the Schengen zone twice a week. For this purpose, Europe is divided into areas with 1 to 3 million inhabitants (which corresponds more or less to a Belgian province). This generally corresponds to the NUTS level (Nomenclature of Statistical Territorial Unit). France, Portugal, Spain and soon Switzerland and Croatia are subject to an assessment at NUTS 3 level: by 150,000 to 800,000 inhabitants.

For the Suisse, this means that the cantons Valais and Vaud may change color, change to vert, while Geneva stay at rouge. The FPS Foreign Affairs website puts these areas updated every day towards 16h, you can stay informed there. Be careful, however: countries may implement additional measures for Belgians; these restrictions are also listed on the FPS Foreign Affairs website.
