A recent study reached an exciting conclusion, that men who have a finger with a longer victory are at a lower risk of death from the emerging coronavirus (SARS Cove 2) that causes Covid-19 disease. In another study, researchers revealed the presence of the Coruna virus in the milk of a mother who was infected with it.

We start with Finger Ring and Corona, as the study, published in the Early Human Development journal, linked finger finger length and risk of corona death due to its possible relationship to testosterone levels, and the study quoted Newsweek in a report.

The researchers studied what is known as the digit ratio, which is calculated by dividing the index finger length (known as "D2") by the finger ring length (D4). It is believed that this ratio indicates the level of exposure to testosterone in the fetus in the womb, as when the ring finger is longer, this indicates a higher exposure to hormones such as testosterone in the womb.

The study included data from an online survey of 103,482 men, 83,366 women from 41 countries. The team found that men who had fingers with a longer victory were at a lower risk of death or severe condition from Covid-19 disease.

"Our findings support an association between low prenatal testosterone (by recording a lower finger finger length) and severity of Covid-19 disease, and higher male mortality," the research team wrote. Protects from the dangerous effects of Covid-19 ".

However, the research team acknowledged that the study was limited, that more research is needed to confirm the link between Covid-19 and testosterone, and that no one should feel safe from the virus.

"Everyone should follow government guidelines in their country, stay at home and practice social divergence when advised," Alan Bessie told professor of masculinity at Sheffield University in the United Kingdom.

"Moreover, everyone should wash their hands 6 to 10 times a day, regardless of the finger ring's length."

Corona virus appears in breast milk

On the other hand, researchers revealed the presence of the Corona virus in the milk of a mother who was infected with the Corona virus, but they were not yet certain whether the infant had passed the virus from his mother's milk, knowing that the infant had been infected with Corona.

Virologists from the city of Ulm in southwestern Germany discovered for the first time the presence of the Corona virus in the milk of one of the infected lactating women.

The newly born child is infected with the virus, but specialists have not been able to confirm that his infection was caused by the milk of his mother or by infection with her breath, for example. This news was published in the specialized medical journal "Lancet".

The World Health Organization has not yet confirmed that the Corona virus can be passed on to infants through breast milk. According to the WHO Regional Office for the Eastern Mediterranean website, which issued "Advice on breastfeeding during an outbreak of the Corona virus (Covid-19)", breastfeeding protects newborns from disease and also helps to protect them throughout the period of breastfeeding and childhood.

And breastfeeding is especially effective against infectious diseases, because it strengthens the immune system by transferring antibodies directly from the mother to the infant.

"As with all confirmed or suspected cases of the emerging coronavirus (Covid-19), mothers who show any symptoms and who are breastfeeding their children or are in direct contact with their skin, should take precautions," the office says.

The office provided advice to breastfeeding mothers, including:

1- Maintain respiratory hygiene, including during feeding. If you suffer from respiratory symptoms such as shortness of breath, you should use a medical mask (muzzle) when approaching your child.

2- Wash your hands thoroughly with soap or disinfectant before and after touching your child.

3- Clean and disinfect any surface you touch frequently.

4- If you are severely ill with the virus or have other complications that prevent you from caring for your child or continuing direct breastfeeding, squeeze the milk from the breast to safely feed your baby.

Wearing gags inside the house

We move on to another study that revealed that wearing masks inside the home can prevent transmission of the emerging corona virus.

The results of the study, published in the British Medical Journal, based on interviews with Chinese families conducted by doctors and academics in Australia, China and the United States, indicate that precautionary measures, such as the use of masks, disinfection and social spacing inside homes, can prevent the transmission of Covid-19.

The authors of the study - including specialists from the Beijing Center for Disease Control - confirm that the research shows that wearing masks at home is "79% effective in preventing the transmission of infections before symptoms first appear."

During the study, 460 individuals from 124 families in Beijing were interviewed, each of whom had at least one confirmed case of coronavirus, in which they were asked about the internal preventive measures used before and after the onset of symptoms, and positive results were confirmed in the first sufferers of the family.

The study authors believe that curbing the spread of the virus within the family is crucial to contain it more broadly.

Separately, the World Health Organization notes that "wearing a medical mask can limit the spread of some respiratory viral diseases, including Covid-19."

Wipes do not always prove infection

We conclude from Germany, with a statement issued by the doctors of the University Hospital Freiburg in the "Deutsche Medzinche Fuchenstreft", that swabs taken from the mouth, nose or pharynx - common forms of testing for infection of the emerging coronaviruses - may give negative results for a case already infected with corona.

According to the data, the case involved a 46-year-old patient who went to the University Hospital Freiburg with symptoms of cough and fever a week after its appearance. After the three negative smears he underwent, doctors were able to establish the presence of genes of the virus in the end, analyzing the secretions of the respiratory system (sputum).

By this time the patient's symptoms of the infection had disappeared, and although he had many risk factors due to obesity, high blood pressure, high levels of blood fat and high blood sugar, he survived the injury without major complications.

It should be noted that smears from the mouth, nose or pharynx are a common practice for proving the emergence of an emerging coronavirus, but there are increasing indications that this method is not always reliable, according to doctor Daniel Hornus of the University Hospital Freiburg.

Hornus and colleagues recommend that genetic testing be tried on other vital materials, such as sputum, deep respiratory secretions or stools, when laboratory values ​​and CT results indicate infection of the emerging coronavirus.
