Covid 19 from the networks point of view
08
Aug
Social networks imply a relationship with their closest neighbors
that are considered as vertices of the networks, and the propagation of the virus is seen as the possibility of a node of the network transmitting to another, as the theory of small worlds (small words) states that each person (each node) is separated from the other, by just six steps of separation, transmission is evident.
Whatever the strategy, testing should always be present, but the cost makes many not adopt this protocol, not knowing who is infected and how to prevent and isolate the virus.
The strategy of isolating environments is not efficient, although keeping environments open and ventilated is a good protocol, in closed environments it does not mean that the viruses are more in certain environments, of course except for the contaminated treatment environments where it is evident that the virus is present. , the Japanese strategy is to hospitalize only serious cases.
Thus, several strategies adopted can be more or less effective, the Chinese is the most obvious, which is zero tolerance, the lockdown, if everyone is isolated there is no transmission, but the Japanese is one of the smartest, and the numbers prove, that is to identify the nodes most susceptible to the contagion of serious cases, so the risk groups are the most monitored and tested there.
According to Japanese infectious disease specialist Sachio Miura, from the Nagasaki University School of Medicine, those with mild symptoms are advised to treat at home, thus avoiding a rush to hospitals, where overcrowding of patients becomes a breeding ground, which in the theory of networks would be called hubs, from which networks proliferate and transmit in smaller steps.
The different health bodies always have specialists in diseases, but the protocol strategy must be thought of globally (in a network), the number of cases and deaths has dropped only because the virus is less lethal, but lethality could be avoided with smart strategies.
International Day of Friendship
30
Jul
The date of International Friendship Day was established by the
UN to remember solidarity between peoples, respect for diversity and I make a special repost of content from this blog in this regard:
The philosopher Plato defined friendship as “the reciprocal predisposition that makes
two beings equally jealous of each other’s happiness”, Augustine of Hippo affirmed that “being a friend merges us in the friendship of being; friends are one soul” and Aristotle seems to merge the two thoughts: “friendship is a soul with two bodies”.
It was Aristotle in Nicomachean Ethics dedicated two books to the study of philia and friendship, who defined friendship in three types: for interest, that for pleasure, for interest and true friendship, the first is easy to identify because it is the pursuit of mutual pleasure, the second because they are useful to each other, and the third, it is possible between good men because they desire good for its own sake and do not place pleasure or interest above friendship.
In chapter IXI the Peripatetic philosopher states:
“Perhaps we can say that there is nothing strange about breaking a friendship based on interest or pleasure when our friends no longer possess the attributes of being useful and pleasant; in fact we were friends with those attributes, and when they disappear it is reasonable not to continue in love. ” (Aristotle, IX, 3, 1165b) .
In the chapter “The partner and the neighbor” of the book “History and Truth” by Paul Ricoeur he will talk about the difference between these relationships, he talks about charity: “Charity doesn’t need to be where it appears; it is also hidden in the humble and abstract post office, the social security; it is often the hidden part of the social”, Paul Ricoeur, Le socius et le Prochain (1954).
We are reminded by the philosopher that just as institutions can only have corporate relationships, they can also have interpersonal relationships, of affection and solidarity and that make them less cold and less bureaucratic, where one sees not a client or a service more, but a neighbor in which one may be interested.
It is not by chance that it is a chapter of History and Truth, because the truth is only established between true and close friends, and if they are partners, it will only be to be closer.
The Twinkl website referenced this post in function of this date, thanks for the reminder.
War and famine
26
Jul
War is not just a dispute over markets and measuring “ideals”,
it is above all an atrocity on a scale, if murder is reprehensible why wouldn’t it be a war? during the Serbia/Bosnia war I asked a Serbian activist why she wanted to destroy Bosnia, she told me that they were historical factors that would be difficult to explain, but she said that her country was a “victim” of bombings that had no justification.
Such is hatred, intolerance and the absence of dialogue, often concealed with docile words to win public opinion, but every war has as its principle some atrocity, some unjustifiable hatred and some cultural intolerance (it can be of many types), not there is no other way to go back other than repentance (on both sides of course) and acknowledging that they chose the worst way, of course, and then sitting down at the table.
One of the consequences, already inevitable, even if there is an agreement for Ukraine’s grain exports, will be the lack of grains on the world market, as shown in the chart above, the country at war is responsible for 42% of sunflower oil in global exports. , 16% of corn, 10% of barley and 9% of wheat (2019 data, see graph) as Russia exports fertilizer and gas to Europe.
There was an agreement mediated by Turkey, but due to the war it is a fact that part of the production was lost and the price of food has already risen worldwide, the current crop will be exported, but little or nothing can be said about future crops, good part of the population left Ukraine, including in rural areas.
It is difficult for a process of regression, apparently throughout the world the confrontation and cultural and social hatred has spread, even among those who should proclaim peace.
Last week we explained the importance of friendship and empathy between men for a true spirituality, which can help civilization in this difficult process.
There is only one way, to change the climate of empathy, peace and solidarity among people, so that politicians and leaders who grow up around hatred may lose ground.
Covid in decline and WHO shifts focus
25
Jul
With the number of deaths above 200 in Brazil, Covid is still a
concern, since the number of cases has dropped below 50 thousand ‘which shows a downward trend, but care protocols and care with protocols are still necessary. .
The World Health Organization (WHO) in a document released this Friday (22/07) announced that a new global strategy to increase vaccine coverage against Covid-19, especially among the most vulnerable populations with comorbidities and advanced age, where aims to reach 100% vaccinated.
The strategy is correct because as the virus circulates, new variants may appear, and as it is very difficult to reach 100% of the population or to lockdown, it is an effective strategy.
Monkey smallpox represents a new concern, the number of cases is growing worldwide, and in Brazil there are already more than 600 cases, now with internal transmission, but the number of cases is increasing worldwide.
Transmission can occur either through close contact with injuries or through bodily fluids, respiratory droplets and contaminated materials such as personal clothes and bedding, and according to health agencies, , between human beings in physical contact between close people who are symptomatic.
Precautions therefore must be to avoid contact with contaminated materials and close people who show symptoms.
Covid on the rise and missing protocols

Although the rhetoric is about the use of masks, distancing
and sanitizing alcohol gel, the ideal would be a serious policy of testing, in practice, the number of cases increases and there is no control.
The moving average of cases in Brazil is already the highest since March 11 when it recorded 46,895, now it stands at 46,137 with a daily total of 69,231, and with the number of deaths at 347, data from the 23rd because weekend data usually be incomplete, and we have also posted that the likely number is likely to be higher due to tests done in pharmacies and asymptomatic.
The number of deaths, with a variation of 8% in relation to 14 days ago, indicates a trend of stability, in total this indicates that despite the number of cases increasing the lethality is decreasing in percentage, so there is no increase in the lethality of the disease. current active strain.
The outlook is for milder weather until mid-July when a cold wave returns, it may indicate a less infectious period, if the trend continues at the end of July there may be a new high in the current wave, waiting for the new strains are no longer lethal.
According to the newsletter of the Fiocruz Genomic Network (Brazil), the BA.2 variant of the omicron is the dominant one with 63.3% of the samples between June 3 and 16 in Brazil, while the XQ variable (XAG*) appeared in 79 samples, which indicates already a mutation in progress.
The variant XQ was renamed XAG according to the revisions of the Pangolin lineage classification system, in the world there are about 100 lineages of the Omicron BA type.
According to the researchers, cases of reinfection by Sars CoV-2 occur frequently, due to the circulation of variants of concern (VOCs) and so care and protocols must be maintained, not just in rhetoric or on paper only.
Between the clearing and the dark

There must be effective forces fighting for peace, unfortunately a good
part of the western media is polarized and is incapable of making a sensible reflection on the horrors and folly of war, not because of ignorance of its effects, the two wars have already shown, but because of of childish and fanatical behavior on both sides.
The threat of closing embassies in Russia, the missiles already fired in North Korea, the war that is increasingly bloody in Ukraine, with heavier and more lethal weapons, is heightened by the media that goes Between the clearing and the dark
About embassies, US Secretary of State Antony Blinken made a joke (in bad taste in my view) of dedicating the song “We are Never Ever Getting Back Together”, by Taylor Swift, to Putin, meaning that they will never be completely separated. .
It is clear that Russia has turned to Eastern Europe and dreams of an enlarged Russian federation, while China has never stopped dreaming of Taiwan’s recovery, and North Korea can be another piece in this war that advances with “care” , but it seems to have a dark purpose.
The clearing, in the context in which it was developed by Heidegger, means an opening in the middle of the forest, in the middle of the darkness, where being must emerge, and what is appropriate for modernity is also appropriate for a moment of a world war seen in a horizon, because it is opposed to beings, economic, social and even political materialities, thus appears Being, life and its logic, its “lebenswelt”, as Husserl would say.
There is a shadow, or a darkness that runs through the minds of humanity, war does not seem to be what it is: a serious civilizational danger, the end of arguments and dialogues, the denial of the Other as a Being, of its culture and its options and convictions, and this is darkness.
The biblical reading says: if the salt becomes tasteless, with what will we salt it? It will be of no use to anything else, but to be thrown away and trampled underfoot by men (Mt 5:13), there must be light and wisdom.
Peace is always possible and desirable if we have tolerance and understanding with the Other.
Covid in global fall and new disease
23
May
The WHO announced a worldwide drop of 21% in world infections,
in Brazil it remains at a slight increase and is already worrying, but the biggest health concern is the emergence of monkeypox.
In the case of Covid 19 in Brazil, hygienic care and disease protocols are still needed.
The endemic started in the Democratic Republic of Congo, in 2016, there were also cases in Sierra Leone, Liberia, Central African Republic and Nigeria, which suffered the biggest recent outbreak, data indicate that a recent increase in incidence was the interruption of vaccination against the disease. smallpox in 1980, and now cases have appeared in Europe, with local infections and the first cases in the US.
A 26-year-old Brazilian who passed through Portugal and Spain, countries that already have several cases of infections, was diagnosed in Germany, is isolated in a clinic and has mild symptoms.
Clinical differentiation between monkeypox and smallpox and chickenpox (a hepervirus and not a pox virus) is difficult as medical reports, PCR (polymerase chain reaction) examination or electron microscopy are necessary to detect the infection, there is no safe treatment , however, the disease is not lethal, its rapid expansion in Europe is already a global health concern.
The treatment indicated is that of simian smallpox, supportive, data from cases in Africa indicate that the smallpox vaccine is effective in 85% of cases as the disease is linked to the smallpox virus.

The Mapuche, ontology and peace
18
May
One of the most resilient native peoples of the colonization of the
Americas is the Mapuche people, there are more than a million people who study in the south of Chile and Argentina, and find themselves once again betrayed by governments that promise freedom to live as a nation and be respected.
But the truest interpretation, which refers to a kind of original ontology, is Mapúmche, which means all beings that inhabit the cosmos: living beings, trees, stones, water, wind, etc. it is likely that the arrival of the Spaniards reduced the word to Mapuche, which simply means peoples of the land.
I read with sadness that the new Boric government, which promised in a campaign to suspend restrictive measures in the region that receives the colonized name of “La Araucanía” (name given by the Spanish colonizers) has returned to be militarized because of claims to indigenous lands.
The Minister of the Interior, Izkia Siches, said when sending soldiers to the region: “We decided to make use of all the tools to provide security” to the region and the long saga of the Mapuche continues.
The Mapuche have always known that language unifies them, Western ontology says that language is the abode of being, and they rejected the name Araucanos, which resembles the Araucaria and transforms them into aboriginal peoples, also the exotic idea that Mapuche would be derived from the Greek, of a historian Kilapan Lonko, who wrote “El origen greco de los Araucanos”, a falsification of history.
Many Mapuche words entered the Chilean language, choclo (corn), huacho (illegitimate child), laucha (small mouse), quiltro (dog), ruca (house), etc. and a popular interpretation of mapuche is mapu (land), che (people in the sense of people), thus several places and cities in chile have the prefix hue: Carahue, Colhue, Pencahue and others.
The extract from the documentary “Los Araucanos”, entitled “Mapuches: idioma o mirror da alma” from 1978, which mistakenly calls them Araucanian peoples, shows the importance of the language that the Mapuche have always had, which refers to the ontology of the native peoples.
The historian and professor at the University of Chile, the Mapuche Rodrigo Huenchún, also explains that culture has been increasingly appropriated as a political manifestation since the Pinochet dictatorship. Elisa Loncon and many others.
The recognition of the culture of peoples, if its original roots are at the root of true peace, this is the drama of modern man, of forgetting being, his experiences and his roots.
Covid 19 rising trend in Brazil
09
May
In numbers Publisher by the Brazilian Ministry of Health itself,
ranging from May 4th to 5th, Saturday and Sunday in general there is underreporting, the epidemiological bulletin has already recorded a high of around 8.9% with 21,682 new infections and 137 deaths from the disease. .
This trend has continued since the beginning of the month and reaching the rate of 15% will be considered a new high and a new wave, although the number of deaths is lower and a moving average remains below 100 daily deaths, being average and having number above 100 could rise again, as the average number of infections is higher and the number of deaths is lower because the strain is less lethal than the previous ones.
The calculation of moving averages is done by experts using the records of the last 14 days and dividing the total by 14, it is possible to have a broader view of the current moment of Covid.
There is no clear analysis of this slight increase, perhaps a seasonal effect of the arrival of the cold that favors respiratory infections, but this would be very premature because it is happening in the southern hemisphere in less than a week, perhaps the greater capacity of infections of the second omicron lineage, BA.2, the worrying thing is that it favors the circulation of the virus and the danger of new variants.
Except for specialized sectors that alert to the issue, little attention is paid to the most accurate information about this future of SARS-Covid, only the situation in China that remains serious and now even with reports of inhumanities due to an excessive and strict #lockdown.
In Brazil it is electoral period and this does not favor correct information about Covid.
Study reveals danger in new variants
02
May
The world number of deaths from Covid 19 decreases, but
with resistance to say that the variants can be less lethal and make the number fall to zero, while the health crisis hits China’s largest cities hard, including now the capital Beijing, without a clear diagnosis.
In Brazil, the falling number now seems to stabilize with small increases, at times it exceeds 100 daily deaths of the moving average, reaching 200 and the number of infections does not fall, reaching close to 20 thousand cases, which is the scenario future?
A Brazilian study, carried out by researchers from USP-Brazil at the Institute of Biomedical Sciences (ICB) and the Institute of Chemistry (IQ) as well as researchers from the Hospital Sírio-Libanês do Brasil, reveals that the new variants of SARS-COV-2 are more likely to circumvent the population’s immune defenses and should emerge in the coming months.
The work was published by the journal Viruses and reviews more than 150 articles, investigated the immune system’s evasion capacity, transmissibility and effectiveness with vaccination in addition to the mutation potential and the result serves as a warning.
The article reads verbatim “Growing evidence has shown that mutations are being selected in favor of variants that are more capable of evading the action of neutralizing antibodies” and shows that the authorities’ lack of concern with the pandemic is political.
In terms of protocols, individual concerns follow, there is no clear public policy
