células de coronavirus

In just about one week COVID-19 cases had risen around 20% and obviously there are more death cases; nevertheless, it is important to avoid panic and also avoid to spread unreal information  or information without scientific support. That is why in this occasion we will talk about some myths and realities about coronavirus. 

1.- Face masks do not protect against coronavirus: there are no scientific studies which indicate that face mask use in people without symptoms could be useful to avoid the coronavirus. Panic shopping of these articles had caused a huge increase in their price. Also, most people do not use face masks appropriately  and this type of masks have not enough sealing to avoid that the virus can pass the margins of the face mask. If a person presents cough or sneezing it is recommended for them to use the face mask in order to avoid spreading of germs to close contacts, anyway, it will always be preferable to stay at home in these circumstances.

2.- The coronavirus could be transmitted by food: Up to date, there is no evidence that this is possible. In previous cases of different types of coronaviruses like SARS and MERS there was no proof about this. In any case, cooking food at least at 60° C (140 °F) for 30 minutes is enough to kill the virus.

3.- Vitamin D prevents coronavirus: recently this information has spread without scientific evidence. A study published in 2019 demonstrated that in patients with vitamin D deficiency, supplementation of this substance helped to reduce the risk of suffering respiratory infections in geneeral.

4.- Intake of vitamin C prevents respiratory infections. Multiple studies published during 2007, 2017 and 2018 described a reduction in the number of respiratory infections in women when they consumed more that 110 mg/day of this vitamin, with no demonstrable effect in men. There is no evidence that child could be protected against respiratory infections when they receive this vitamin supplementation, but there is proof that duration of disease is reduced, there is no evidence regarding coronavirus.

5.- Warm weather and humidity could stop coronavirus dissemination: German specialist Thomas Pietschmann says this can not be predicted because there is not enough information about the virus, it is well known that coronaviruses have a lipid envelope, which is not particularly resistant to high temperatures and that could cause virus disintegration  as ambient temperature goes high; nevertheless, there is no scientific evidence about this.

6.- Pneumonia or influenza vaccines could help to prevent coronavirus infection: The answer is no, none of these vaccines can prevent the virus, but they must be applied when indicated. Until this time, various laboratories are experimenting with around 35 types of vaccines but there are no concrete results at the moment.

We need to remember that at this moment we only have preventive measures to take care of our health and the ones around us.
