Talking or shouting causes us to emit up to 50 times more aerosols (small drops) than when we breathe, so stay silent, use a double or triple layer mask with a good fit, do not eat or drink and open the windows, there may be some measures that reduce the risk of transmission of the coronavirus in environments such as public transport, a waiting room or a supermarket.

“The ideal would be to avoid having people who are not living together in a closed place, but this is impossible and on a daily basis we share with other public transport, lines in supermarkets, waiting rooms for doctors, so there are some issues that we have to take into account account to reduce risks, “said Andrea Pineda Rojas, researcher at the Conicet Center for Sea and Atmosphere Research.

In this context, specialists made a score of some behaviors that counteract daily life postcards such as someone who shouts on the cell phone in the bus, lowers his mask to record a voice message in line at the supermarket or who he starts eating a snack while he waits for his turn with the doctor.

“In the first place it is always important to use a face mask, double or triple layer, covering the nose, mouth and chin with a good fit so that the air always enters and leaves through the chinstrap; this is key, more now with the new variants that they are more contagious, “said Pinera Rojas. And he continued: “Another key issue is not talking, not with someone next door, not on the phone, or sending audio messages because when we speak we emit many more aerosols than when we only breathe and this, which seems like a nonsense, is very important if we think of a space as a collective where there can be up to 50 people, “he added.

In the case of public transport, he stressed the importance of opening the window when sitting down if possible.

In the same sense, the infectious disease physician Elena Obieta recalled that “when you speak, sneeze, laugh or cough, more droplets are emitted (from the big ones and from the girls) than when you are quiet, then there are behaviors that we must treat to incorporate when we share closed spaces with other people “.

“For example, not talking on a cell phone, much less shouting, because it is known that the higher the tone of voice, the more we emit; we do not have to eat or drink either; they seem like small things but they are habits that to the extent that they are incorporated, they can reduce transmission, “said Obieta, a member of the Argentine Society of Infectious Diseases (SADI).

In relation to eating or drinking, the problem is that to do so you have to remove your chinstrap. “If we add to this that when we get together to eat in a group we continue talking then the risk increases,” said Pineda Rojas.

According to the Spanish researcher José Luis Jiménez, who works at the University of Colorado, USA, it is estimated that when we speak we emit 10 times more aerosols than when we breathe and that when we sing and shout that emission increases up to 50 times.

“Aerosols are like invisible smoke that people emit when they breathe or speak. They are very small droplets and for that reason remain suspended in the air for hours; while the largest droplets, the ones we see, fall faster”, explained to Télam Jiménez.

According to the specialist, “the possibility of breathing that smoke from another occurs in two situations: when you are very close, especially without a mask (chinstrap), or when you share the air in a closed room, because the closed space traps the air that that person is exhaling. They are two very common and frequent situations and it has been shown that airborne transmission (through aerosols) is the main route of contagion of the coronavirus. “

These preventive measures also serve to think about the workplace. “If we have to have a talk with someone, the ideal is to do it outside, for example in a patio; the same for eating,” said Pineda Rojas.

The researcher recalled that “although the risk of contagion is much lower outdoors, there are registered cases in the vicinity and generally it is because people speak without distance or mask.”

“That is why the use of the chinstrap should also be maintained outdoors with a good fit and distance to reduce the risk of contagion,” he said.

More vaccines arrive

An Aerolineas Argentinas plane with a million doses of Chinese Sinopharm vaccines took off yesterday from China with its final destination in Buenos Aires, where its arrival is expected for the afternoon of today.

In addition, at dawn another flight left for Moscow to bring more Sputnik V vaccines.

For the country

Free Dead Cow

Self-summoned health workers lifted the cuts in the oil routes around Vaca Muerta in Neuquén and accepted the wage agreement closed by ATE with a 53% increase in quotas until December. To pay the province, it will borrow $ 12.8 billion.

“Do not pay the raises”

The vice president of the National Communications Agency (Enacom), Gustavo López, yesterday urged users not to pay cable, telephone and internet bills if they come with increases since, he recalled, “they are not authorized.” He will draw another resolution to prohibit the cuts of services.

There were 348 deaths and 23,718 new cases

Another 348 people died and 23,718 were reported with coronavirus in the last 24 hours in Argentina, amounting to 62,947 deaths and 2,928,890 positive cases since the start of the pandemic.

There are 5,178 inpatients in intensive care throughout the country, with an ICU bed occupancy of 68.3% throughout the country and 76.8% in the AMBA.

According to the Public Vaccination Monitor, the total inoculated amounts to 7,667,385, of which 6,774,995 received one dose and 829,390 both, while the vaccines distributed to the jurisdictions reached 9,100,608.

Of the total deaths, 200 are men and 148 are women. The deceased men are 99 from the province of Buenos Aires, 31 from the City of Buenos Aires, 3 from Chaco, 4 from Chubut, 4 from Corrientes, 8 from Córdoba, 2 from Entre Ríos, 4 from Formosa, 3 from Jujuy, 5 from Mendoza, 6 from Neuquén, 1 from Río Negro, 2 from Salta, 2 from San Juan (not updated), 1 from Santa Cruz, 15 from Santa Fe, 3 from Santiago del Estero, 1 from Tierra del Fuego and 4 from Tucumán .

Meanwhile, the deceased women are 73 from Buenos Aires, 26 from the City, 3 from Chaco, 8 from Chubut, 3 from Corrientes, 1 from Jujuy, 1 from La Pampa, 8 from Mendoza, 2 from Neuquén, 2 from Río Negro , 4 from Salta, 3 from San Juan (not updated), 1 from Santa Cruz, 9 from Santa Fe, 1 from Santiago del Estero and 2 from Tierra del Fuego.

Wave with high transmission and high effect in young people

Critical hours. In the south of the Buenos Aires suburbs, several clinics house patients with covid even in the corridors in the absence of beds.

High transmission of the virus and the circulation of people -although in decline in the last epidemiological week-, with a strong impact on young people, the most exposed population, and a stressed health system are the keys that describe the second wave of coronavirus in the country.

The main change observed with respect to the first wave is “the increase in infections in people under 60 years of age, especially in the ranges from 20 to 29 years and from 30 to 39” while also growing “in the range of 0 to 9 years”.

In mid-March, from epidemiological week 11, cases began to increase, according to data from the National Directorate of Epidemiology and Strategic Information.

In that week the positive cases were 52,266, 14% more than the previous week, when there were 45,808 cases; in week 12 they were 71,836 (a rise of 37%); in week 13, 103,143 (44% more and almost double that of week 12); in the 14, 149,313 (a growth of 45%).

In week 15, 13% fewer cases were registered, with a total of 129,904, a decrease that was registered after the last circulation restriction measures taken in a focused manner in the AMBA.

In this context, the data on free critical beds, reflected by the Society for Intensive Care (SATI), are worrying: in the AMBA, adding the public and private health systems is low, barely 3.92%.

In the same region, it is noted that the number of people who require more complex assistance because they need Mechanical Respiratory Assistance is high (78.2%). In addition, the available data shows the impact of the circulation of coronavirus in the youngest population, which is the most exposed.

Until April 22, the percentage of adults admitted to national hospitals in intensive or intermediate care units is higher in the group between 40 and 60 years old: 44% of them are in intensive care units (ICU) and 50 , 7% in intermediate therapy units (ICU).
