How dangerous is the cruise ship hantavirus?

Virologists, the imaginative bunch that we are, often name new viruses after the places they were first found. Zika virus was initially described in Uganda’s Zika forest, while the Ebola river, flowing through what is now the Democratic Republic of the Congo, needs no explanation for the dread disease documented there. There are existing case reports of human outbreaks in South America stemming from gatherings and parties. That said, the documented efficiency of the transmission under these circumstances is extremely low Hantaviruses are chips off the same block.

Could the lockdown have side-effects no one has considered?

‘Nothing makes sense in biology, except in the light of evolution,’ the splendidly named biologist Theodosius Dobzhansky wrote in 1973. It’s a good rule of thumb. Despite near-miraculous advances in medical science we remain biological beings, subject to biological laws. None is more central to our understanding of disease than evolution. Yet this theory remains poorly understood and poorly utilized in medicine. And an evolutionary perspective raises important questions about the drastic action we have been taking to confront COVID-19.Most doctors are too busy dealing with the day-to-day deluge of cases to have much time for what they may consider abstruse academic ideas.
