While the Coronavirus is a real concern for many of us, especially in our clinics, and while we are being very proactive in our offices, we want to give you some reasons why we don’t want you to panic.
1. We know what it is
The first cases of AIDS were described in June 1981 and it took more than two years to identify the virus (HIV) causing the disease. With COVID-19, the first cases of severe pneumonia were reported in China on December 31, 2019 and by January 7 the virus had already been identified. The genome was available on day 10.
We already know that it is a new coronavirus from group 2B, of the same family as SARS, which we have called SARSCoV2. The disease is called COVID-19. It is thought to be related to coronavirus from bats. Genetic analyses have confirmed it has a recent natural origin (between the end of November and the beginning of December) and that, although viruses live by mutating, its mutation rate may not be very high.
2. We know how to detect the virus
Since January 13, a test to detect the virus has been available.
3. The situation is improving in China
The strong control and isolation measures imposed by China are paying off. For several weeks now, the number of cases diagnosed every day is decreasing. A very detailed epidemiological follow-up is being carried out in other countries; outbreaks are very specific to areas, which can allow them to be controlled more easily.
4. 80% of cases are mild
The disease causes no symptoms or is mild in 81% of cases. Of course, in 14% it can cause severe pneumonia and in 5% it can become critical or potentially fatal. It is still unclear what the death rate may be. But it could be lower than some estimates so far.
5. People recover
Most infected people are cured.
6. Symptoms appear mild in children
Only 3% of cases occur in people under 20. Symptoms are so mild in children, it can go unnoticed.
7. The virus can be wiped clean
The virus can be effectively inactivated from surfaces with a solution of ethanol (62-71% alcohol), hydrogen peroxide (0.5% hydrogen peroxide) or sodium hypochlorite (0.1% bleach), in just one minute. Frequent handwashing with soap and water (for at least 20 seconds) is the most effective way to avoid contagion.
8. Science is on it, globally
It is the age of international science cooperation. After just over a month, 164 articles could be accessed in PubMed on COVID19 or SARSCov2, as well as many others available in repositories of articles not yet reviewed. They are preliminary works on vaccines, treatments, epidemiology, genetics and phylogeny, diagnosis, clinical aspects, etc.
These articles were written by some 700 authors, distributed 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 articles. In addition, most scientific journals have left their publications as open access on the subject of coronaviruses.
9. There are already vaccine prototypes
Our ability to design new vaccines is spectacular. There are already more than eight projects underway seeking a vaccine against the new coronavirus. There are groups that work on vaccination projects against similar viruses.
The vaccine group of the University of Queensland, in Australia, has announced it is already working on a prototype using the technique called “molecular clamp”, a novel technology. This is just one example that could allow vaccine production in record time. Prototypes may soon be tested on humans.
10. Antiviral trials are underway
Vaccines are preventive. Right now, the treatment of people who are already sick is important. There are already more than 80 clinical trials analyzing coronavirus treatments. These are antivirals that have been used for other infections, which are already approved and that we know are safe.
Another candidate is chloroquine, an antimalarial that has also been seen to have potent antiviral activity. It has been demonstrated that this compound blocks the new coronavirus in vitro and it is already being used in patients with coronavirus pneumonia.
Other proposed trials are based on the use of oseltamivir (which is used against the influenza virus), interferon-1b (protein with antiviral function), New therapies have been proposed with inhibitory substances, such as baricitinibine, selected by artificial intelligence.
Stay calm and have a safe and restful weekend!
