Borderless collaboration is needed for COVID-19-A disease that knows no borders

[...]measures have not prevented the disease from spreading globally; COVID-19 has already spread to almost all countries and regions, and the World Health Organization (WHO) named it a pandemic on March 11, 2020.1 For this reason, some countries have announced a so-called ‘lockdown.’ The host’s immune system has an important role in the transmission of SARS-CoV-2.3 Multiple severe cases within families also suggests a genetic predisposition to COVID-19.4 Thus, international collaboration to better understand the disease pathophysiology of COVID-19 is needed.
