Despite whether we classify the new coronavirus as a pandemic, it is a severe concern. In less than 2 months, it has actually spread over a number of continents. Pandemic means sustained and continuous transmission of the disease, all at once in more than 3 different geographical regions. Pandemic does not refer to the lethality of a virus however to its transmissibility and geographical extension.

Coronavirus - don't panic

What we certainly have is a pandemic of worry. The entire world’s media is gripped by coronavirus. It is right that there is deep issue and mass planning for worst-case circumstances. And, naturally, the repercussions move from the global health sphere into organisation and politics.

However it is likewise ideal that we must not worry. It would be wrong to say there is great news coming out of COVID-19, however there are causes for optimism; factors to think there may be methods to contain and beat the virus. And lessons to discover for the future.

1. We know what it is

The first cases of AIDS were explained in June 1981 and it took more than 2 years to identify the virus (HIV) triggering the illness. With COVID-19, the first cases of severe pneumonia were reported in China on December 31, 2019 and by January 7 the infection had actually already been identified. The genome was readily available on day 10.

We currently know that it is a new coronavirus from group 2B, of the exact same household as SARS, which we have called SARSCoV2. Hereditary analyses have actually verified it has a current natural origin (between the end of November and the start of December) and that, although infections live by mutating, its anomaly rate might not be very high.

2. We know how to discover the virus

Given that January 13, a test to discover the infection has been readily available.

3. The situation is improving in China

The strong control and seclusion procedures imposed by China are paying off. For numerous weeks now, the number of cases diagnosed every day is reducing. An extremely comprehensive epidemiological follow-up is being carried out in other nations; outbreaks are really particular to locations, which can enable them to be managed more easily.

4. 80% of cases are moderate

The disease causes no symptoms or is mild in 81% of cases. Obviously, in 14% it can trigger serious pneumonia and in 5% it can become crucial and even fatal. It is still uncertain what the death rate may be. However it could be lower than some quotes up until now.

5. Individuals recover

Much of the reported information connects to the increase in the number of validated cases and the number of deaths, however most infected people are cured. There are 13 times more treated cases than deaths, and that percentage is increasing.

6. Signs appear moderate in children

Only 3% of cases take place in individuals under 20, and mortality under 40 is only 0.2%. Signs are so mild in children it can go undetected.

7. The infection can be wiped tidy

The virus can be successfully suspended from surfaces with a service of ethanol (62-71% alcohol), hydrogen peroxide (0.5% hydrogen peroxide) or salt hypochlorite (0.1% bleach), in just one minute. Regular handwashing with soap and water is the most effective way to prevent contagion.

Coronavirus - don't panic

8. Science is on it, worldwide

It is the age of international science cooperation. After just over a month, 164 posts could be accessed in PubMed on COVID19 or SARSCov2, as well as many others offered in repositories of short articles not yet evaluated. They are preliminary works on vaccines, treatments, epidemiology, genes and phylogeny, medical diagnosis, medical aspects, and so on.

These posts were composed by some 700 authors, dispersed throughout the planet. It is cooperative science, shared and open. In 2003, with the SARS epidemic, it took more than a year to reach less than half that number of short articles. In addition, many scientific journals have actually left their publications as open access on the subject of coronaviruses.

9. There are currently vaccine models

Our capability to develop new vaccines is spectacular. There are currently more than eight projects underway seeking a vaccine against the new coronavirus. There are groups that work on vaccination tasks against comparable viruses.

The vaccine group of the University of Queensland, in Australia, has actually revealed it is currently working on a model using the technique called “molecular clamp”, an unique technology. This is simply one example that could permit vaccine production in record time. Prototypes might quickly be evaluated on humans.

10. Antiviral trials are underway

Vaccines are preventive. Today, the treatment of individuals who are currently ill is essential. There are already more than 80 medical trials evaluating coronavirus treatments. These are antivirals that have actually been utilized for other infections, which are already authorized and that we know are safe.

One of those that has actually already been tested in humans is remdesivir, a broad-spectrum antiviral still under research study, which has been checked against Ebola and SARS/MERS.

Another candidate is chloroquine, an antimalarial that has actually also been seen to have potent antiviral activity. It is understood that chloroquine obstructs viral infection by increasing the pH of the endosome, which is required for the combination of the virus with the cell, therefore inhibiting its entry. It has actually been demonstrated that this substance obstructs the new coronavirus in vitro and it is already being used in clients with coronavirus pneumonia.

Other proposed trials are based on making use of oseltamivir (which is utilized against the influenza infection), interferon-1b (protein with antiviral function), antisera from individuals who recovered or monoclonal antibodies to neutralise the virus. New therapies have been proposed with inhibitory compounds, such as baricitinibine, picked by expert system.

The 1918 influenza pandemic caused more than 25 million deaths in less than 25 weeks. Could something similar happen now? Most likely not; we have actually never ever been better prepared to fight a pandemic.

Pandemic does not refer to the lethality of a virus however to its transmissibility and geographical extension.

It would be wrong to say there is great news coming out of COVID-19, but there are causes for optimism; factors to believe there may be ways to beat the infection and include. The very first cases of AIDS were explained in June 1981 and it took more than two years to determine the infection (HIV) causing the illness. With COVID-19, the first cases of serious pneumonia were reported in China on December 31, 2019 and by January 7 the infection had actually already been determined. It is known that chloroquine obstructs viral infection by increasing the pH of the endosome, which is required for the fusion of the virus with the cell, therefore preventing its entry.
