[Health statistics and invisibility by sex and gender during the COVID-19 epidemic].

Reports on COVID-19 from the Spanish Health Ministry are valuable, but incomplete, with the perverse effect that the susceptibility to COVID-19 by sex is unclear. Prevalence of COVID-19 by sexes differs between countries. The trend in Spain shows an unequal pattern, initially more frequent in men, but women outnumbered them from March 31, after two weeks lockdown. Infections are more frequent in women than in men in close contact with probable/confirmed COVID-19 cases. Consistent with deaths in men, they are hospitalized more frequently than women: Significant gender differences in signs/symptoms can drive this pattern, already observed in other pathologies. In late April, excess mortality is the same in women (67%) than in men (66%). But, lack of exhaustive information on deaths from COVID-19 in non-hospitalized patients may contribute to lower notification of deaths in women. Invisibility of data by sex and gender is probably affecting negatively women with COVID -19 more than men.
