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.
