Recognizing the extent to which the COVID-19 outbreaks affects women and men differently is hugely important. Some preliminary data suggested that more men than women are dying, potentially due to sex-based immunological differences, higher rates of cardiovascular disease for men and lifestyle choices, such as smoking. However, the experiences and lessons learned from the Zika and Ebola outbreaks and the HIV pandemic demonstrate that robust gender analysis and informed, gender-integrated response are vital to strengthen the access and acceptability of the humanitarian services needed to meet the distinct needs of women and girls, as well as men and boy and LGBTI people.
