"The two of us acted separately and inquired about the situation from the people in West Lanes 7, 8, 9, 12, and 14."
Xu Qingyi's face was solemn and he rushed to the white flue."
Okay."
Soon the two of them took action, checking the situation one by one."
Who!"
When Xu Qingyi knocked on the door of the first house in West Seventh Lane, there was a voice of inquiry in the house."
This lady, I am a doctor at the Rejuvenation Medical Center, and I came to investigate the source of dysentery infection and check the situation."
Xu Qingyi listened to the voice of an elderly lady, and she said loudly. ’With a creak, the door soon opened, and the lady beckoned Xu Qingyi and said, "Come in, take a look at my house and see if there is anything that causes illness." ”"Auntie, don't worry, the spread of this dysentery is mainly through food and water, and it can only be infected if you strictly control your daily habits.For example, wash your hands frequently, boil bedding and clothes in the sun, do not drink raw water, pay attention to personal hygiene, as long as you do what I say, you will not be infected with dysentery.Auntie, has anyone in your family contracted dysentery?
”Xu Qingyi comforted the eldest lady and asked her to pay attention to the hygiene of her life."
No, it's all right!
It is the Bodhisattva who blesses it.I will definitely listen to you and do what you say. ”"Auntie, you don't have a well at home?"
Xu Qingyi checked the house, backyard and kitchen of this family, and asked strangely after seeing that there was no well in their house.Dysentery comes from the mouth, and it is most likely related to water, so when Xu Qingyi came, it was a little strange that he didn't see this family's well."
There is a well, behind the kitchen.However, in the outer city, it is very precious to be able to dig a well in the house. ”When the lady heard this, she pointed to the covered well behind the kitchen."
Oh, why is that?"
Being able to dig a well at home is very precious, she remembers that when she was in Zhangli Village, every household in the village drilled a well, which was not so precious."
We don't know if it's the location or what's going on in the outer city, not every household can dig a well to get water.Only a few families are able to dig out wells that produce water. ”The lady explained a few words."
In this way, the water for eating, drinking, and washing in your family is drawn from the well in your house, and no one else in your family has contracted dysentery."
When Xu Qingyi heard this, she seemed to understand something."
That's right!
Doctor, do you mean that the people who are suffering from dysentery are drinking unclean water?
”The lady also seemed to understand, and asked.Subsequently, looking glad that he had hit the well, Xu Qingyi was a little amused when he saw it."
It's not clear yet, but it's possible that it's the reason.Auntie, where are the people who do not have wells at home, where are they eating and drinking, and where are the places where they wash their clothes?
”Xu Qingyi asked."
The water to drink is found at the intersection of West Street, and as for the laundry, it is washed in the creek on the edge of the outer city.However, only the people of our West Street washed their clothes in the creek on the edge of the outer city, while the people of East, South, and North Streets washed in the small river in the inner city. ”The eldest lady explained.Xu Qingyi nodded, and had a little guess about this matter in his heart, Xu Qingyi thanked the lady on West Street, left, and continued to knock on the next door.When I learned that someone in this family was infected with dysentery and had been sent to the rejuvenation clinic for treatment, from the inquiry, there was no well in the house, and it was a woman who was infected with dysentery.This is a few points more confirmed than Xu Qingyi's guess before.Subsequently, Xu Qingyi successively investigated the people in the West Seventh and West Eighth Alleys of the west of the city, and found that there were dysentery infected people in their homes, all of whom did not have wells at home, and they all picked up water from outside.The most interesting thing is that most of the people infected with dysentery are women.After Xu Qingyi confirmed a little in his heart, he was no longer investigating the people in Xicheng West Seventh and West Eighth Alleys one by one.The people of West Street do not have wells in their homes, and the water they drink is picked from the intersection of West Street, while the people in other neighborhoods draw water from different places.Could it be that the water source on West Street is contaminated?
There is also washing clothes from the stream, and perhaps one of these two sources has a source of infection.Thinking of this, Xu Qingyi decided to go to the West Street intersection to check the situation of the water source.She came to the intersection and found white smoke coming towards her."
You're here too?"
Bai Yan asked after seeing Xu Qingyi."
I asked more than a dozen families and found that the people in their homes who were infected with dysentery did not have wells at home, and all the water they ate and drank was brought back from outside.So, let's take a look at this well. ”She took a closer look at the surroundings of the well and found that there was no obvious source of pollution and that the well looked clean."
Me too, it's just that the well looks so clear, and there is no testing instrument, and we can't tell if there is a source of infection in this well.It's hard to do it, you have to find someone to do an experiment, drink a sip of this water, and see if you are infected with dysentery. ”After Bai Yan looked into the well, but couldn't see anything, she frowned slightly."
Don't worry, I'll try it."
Xu Qingyi picked up the bucket next to him and poured a small half bucket of water from the well.She carefully observed the well water and saw that it was clear and transparent, without any impurities."
It looks pretty clean."
Xu Qingyi muttered softly to himself, then took a handful with his hand and took a sip gently.Bai Yan looked at her nervously, for fear that she would have problems drinking the well water.But Xu Qingyi didn't seem to be unusual, but showed a satisfied smile."
The water is very sweet, there is no smell or other strange places, it should be fine."
Xu Qingyi put down the bucket and said to Bai Yan.When Bai Yan heard this, he also put his mind at ease, stepped forward, and also took a sip of well water.Sure enough, the well water was so sweet and delicious that she couldn't help but drink a few more sips."
It seems that there is nothing wrong with this well."
Xu Qingyi smiled and said, "Let's go to the creek to wash clothes next, and there is a high probability that the problem is where it will appear." ”"Let's go, go now, find the source as soon as possible, and solve this matter."
Seeing this, Bai Yan took the lead and walked towards the stream on the western edge of the city.When the two of them came to the stream, they saw that the water was crystal clear and the surrounding environment was quite clean.The stream flows rapidly, and the sunlight shines through the treetops and dappled on the surface of the stream, as if adding a bit of vividness to this tranquil scene.The two of them stood by the stream, enjoying this rare tranquility and beauty.
