I think Japan was having testing problems same as US.
Ugh! Sorry again...

Once the temperature rises, the new coronavirus will dissipate? Why spring might indeed be a gospel, and what makes the new coronavirus special, a German virologist answers.
According to the Voice of Germany report on March 1, many people expect that spring will make the situation better. If the new crown virus really resembles the flu virus, it may be considered good news. Because if this happens, as the spring comes, the temperature will rise, the virus will be killed, and the epidemic will disappear.
But these are just people’s good wishes. Thomas Pietschmann, a molecular virologist at the Center for Experimental and Clinical Infection Research in Hanover, Germany, believes that whether the new crown virus will behave as expected, this question cannot be strictly answered because humans Virus awareness is not enough.
“The special thing about this virus is that it’s the first time humans have come into contact with it. Based on the data we got from China, we can conclude that the virus was transmitted from an animal to humans, just once, and then from there Began to spread. “
In other words, unlike the flu virus that almost everyone has come into contact with, our immune system is not ready for the invasion of the new crown virus.
In addition, the current climate in the northern hemisphere is “perfect” for the rapid spread of the virus. The first is air temperature. Viruses transmitted through the respiratory tract are particularly active at low temperatures: “The virus is more stable at lower temperatures. It’s like food can be stored longer in the refrigerator.”
For many viruses, the better the temperature, the worse the day. “The new coronavirus is surrounded by a lipid layer,” Pitzman said. The lipid layer is not particularly heat-resistant, so the virus is killed soon after the temperature rises.
Humidity also plays a major role in the infectivity of respiratory viruses. Pathogens float out of the air after being sneezed violently. “Compared to high-humidity environments, in most drier cold winter days, small droplets with viruses stay in the air for longer,” Pitzman said.
In addition, infection with the virus is not only related to age and health, but also depends on gender. Estrogen can also help women fight off the virus.
“There are genetic reasons for this, because some genes related to the immune system, such as those responsible for identifying pathogens, are encoded on the X chromosome.” Because women have two X chromosomes, There is only one male, so women obviously have an advantage in this regard.
The Voice of Germany specifically mentioned that perhaps when the northern hemisphere spring blooms, the new crown epidemic will really end. However, according to the WHO, at least 20 new crown cases have been detected in Australia, and Brazil has also. Both countries are in the southern hemisphere. The winter there has not yet begun.
