Science: The new crown outbreak will have an impact on human fertility.

New Crown pneumonia is still raging around the world.
the number of people infected globally has exceeded 16 million, which has killed about 650,000 people and has had a serious impact on countries around the world.
, however, the impact of new pneumonia on humans is much more than that.
recently, researchers from Italy found that the black swan event in the new outbreak of pneumonia could lead to a decline in fertility worldwide.
the study, published in the journal Science, was published in the journal The COVID-19 pandemic and human fertility, translated Chinese into the Study of the New Crown Pandemic and Human Fertility.
historical experience tells us that when human society experiences famine, disease or war and other disasters, the population will decline sharply, but after the disaster, as the living environment becomes better, there is usually a number of "birth tides".
However, researchers say the effects of the new coronapneumonia may be longer and may even affect a generation.
researchers say the isolation of the new crown pneumonia has caused huge economic losses around the world, with people's incomes and willingness to spend falling, and uncertainty about the future making the cost of raising children higher and people becoming more cautious about having children.
in high-income countries, factory shutdowns, shop closures and school closures to reunite family members due to long-term social segregation policies, does that mean that people are under heavy financial pressure to have another child? I'm afraid I'll have to think it over.
on the other hand, most families opt for assisted reproductive technology because of the usually high maternal age in developed countries, but these services are temporarily unable to do so during periods of social isolation. "While it's hard to make accurate predictions, fertility is likely to decline, at least in high-income countries, at least in the short term," said Arnstein Aasve, a professor of social politics at the
.
", "For low- and middle-income countries, with the rapid economic development, the deepening of urbanization and the liberation of women in recent decades have led to a gradual decline in fertility rates in these countries, creating a social trend.
and the current economic downturn will make them think twice about the cost of raising children.
speculated on the reproductive trajectory of the new coronary pneumonia affected by the regional income level.
researchers say the impact of the new pneumonia outbreak on our lives will continue, and the decline in fertility rates around the world will have an inevitable impact on social aging and economic development.
at the same time, there is no sign of a rapid economic rebound, the world should be prepared to meet the challenges together, towards the future.
