8:30 p.m.

In Gu Yanan's ward, Nan Hanfei stood by the bedside, peeling apples while talking about what soup he would stew for Gu Yanan tomorrow.

While speaking, Xiao Chu hurriedly ran into the ward, squatted directly beside Gu Yanan's bed, and asked worriedly, "Sister Yanan, I heard that you were injured and bled a lot, is it serious?" Do you need a blood transfusion from me? ”

Gu Yanan smiled and shook his head, "It's okay, I don't need a blood transfusion at all, in fact, I didn't have to be hospitalized, it's just that my brother made a big fuss, he had to arrange me in this ward, I had no choice but to observe for a day before I said, why did you come back?" ”

"When I heard that you were injured, I rushed back immediately and sent specimens to the Municipal Disease Control Laboratory by the way." Xiao Chu realized something, and suddenly changed his words, "The main thing is to come back and send specimens to have a chance to see Sister Yanan." ”

Nan Hanfei patted Xiao Chu on the shoulder and quipped, "Our mobile blood bank is back, what does Xiao Chu want to eat to show his gratitude?" I'll make one for you tomorrow. ”

Xiao Chu smiled shyly, "I didn't donate blood this time." ”

"Although I didn't donate blood, but when I got my mind, I must make something delicious for you, say, what do you want to eat? I'll make chicken soup for your sister Yanan tomorrow, do you want to drink it? ”

"Yes."

"Okay, you can help me when I get back in the evening." Nan Hanfei said with a smile.

"How can you help?"

"Handle live chickens." Nan Hanfei said it as a matter of course, it seems that he has to eat the food he cooks, and he has to give him a hand.

Xiao Chu nodded seriously, "Okay, brother-in-law." ”

Nan Hanfei, who called "brother-in-law", was extremely ironed in his heart, "Young man, there is a future." ”

Gu Yanan interrupted the two, "Don't let Xiao Chu work, he has been busy for a few days and nights without a good rest, let him go to bed early at night, and he will definitely go to the Fairy Lake tomorrow to continue to be busy." Xiao Chu, how's the situation over there? ”

Gu Yanan successfully turned the conversation to work.

"So far, there are no patients with filariasis symptoms in the village I am in charge of, but according to Sister Yanan's request, the mosquito control operation is ongoing."

"Well done, all prevention and control measures are in place until the results of the laboratory tests are available. When killing mosquitoes, it is necessary to take protective measures to avoid being bitten by mosquitoes. ”

"I understand that the people in the local county disease control are very experienced, and I have to learn from them in some places."

"Well, many of the people in the county disease control are employees of the old epidemic prevention station, and some people are like Zhou Lao, who also participated in the prevention and control of filariasis, and now the epidemic has rekindled, and many measures are the same as back then."

"Oh, by the way, Sister Yanan, when I came back, the people from the county disease control also asked if this outbreak should be the same as before, and the whole people in the epidemic area should take pyrimethazine salt for prevention."

"This is to be evaluated based on the results of the flow survey......"

While the two were talking about work, Nan Hanfei peeled the apple and divided it into two, half of which was handed to Gu Yanan and half to Xiao Chu.

Someone knocked on the door again, and this time it was Chu Qingfeng who came in.

Xiao Chu subconsciously explained to Gu Yanan, "I didn't tell my brother the news of Sister Yanan's hospitalization. ”

"I said it." Behind Chu Qingfeng, Gu Jiashu appeared.

"Brother?!"

Gu Yanan didn't understand what his brother Gu Jiashu meant, didn't he always support Nan Hanfei? Why did you tell Chu Qingfeng the news again?

Chu Qingfeng was about to express his concern to Gu Yanan, but was stopped in front of him by Nan Hanfei.

Nan Hanfei said with a smile, "Mr. Chu said before that he wanted to cooperate with Nanmu Group, and today I just had time to talk to you about it." ”

Chu Qingfeng hesitated for a moment, but finally flew out of the ward with Nan Han, for him, the immediate business cooperation was more important.

When the two of them got out of the ward, Gu Yanan took his brother Gu Jiashu's hand and asked in a low voice, "Brother, what's the matter?" Why did you tell Chu Qingfeng the news of my hospitalization? ”

"He has been inquiring about you with Jiahui recently, so I told him the news of your hospitalization directly, so that he could also see the situation clearly, after all, I told Nan Hanfei first, and then told Chu Qingfeng, my brother's meaning is already obvious."

"I see, you asked him to come to see me and Nan Hanfei to show affection, and cut off his thoughts. But not anymore, I've made it clear to him before. ”

Gu Jiashu nodded in acquiescence, and then looked at Xiao Chu, he didn't like these two brothers very much, but Xiao Chu was Xiaomei's colleague, and he had saved Xiaomei and given her a blood transfusion, so his attitude towards Xiao Chu was better.

"Xiao Chu, you go back and rest, I will take care of you here, your disease control has been busy recently, rest well and maintain your strength." Gu Jiashu said softly, "And I know that this filariasis prevention and control is not an overnight thing, there is still a long time to do monitoring work in the future, Yanan is injured now, and a lot of on-site work has to be troubled by you, so go back early to rest." ”

Xiao Chu also felt that Gu Jiashu's attitude towards him and his brother Chu Qingfeng was different, and he understood the kindness, nodded and agreed, "Well, I'll go back with Officer Nan in a while, I promised him to help him." ”

Nan Hanfei, Xiao Chu and Chu Qingfeng left together.

The three of them lived in a community and went back together, chatting on the way, although they had guns and sticks, they also had a common topic.

It is said that three women are in one play, and now three men are together, and it is also a big play.

Two days later, Gu Yanan was discharged from the hospital.

During the hospitalization, the flow investigation work in several villages around Fairy Lake was completed, and the data was returned one after another, and Gu Yanan formulated the next prevention and control measures based on the flow data.

According to the incidence of microfilariaemic disease among the residents of the villages around Fairy Lake, it was decided that all the residents in the endemic area should take pyrimethazine salt, which can not only cure the disease but also take preventive measures, and other residents with symptoms of swelling of the body of the fire will receive separate treatment.

Mosquito control work around Fairy Lake has also begun to progress steadily.

Mosquito monitoring is carried out regularly around the Fairy Lake to complete the Breto index.

After being discharged from the hospital, Gu Yanan returned to the CDC and sequenced the insect samples isolated from the epidemic in the laboratory, and found that the Malayan filaria had a certain homology with the Malayan filaria that was prevalent in Lianhai City before, but it also mutated, which belonged to intraspecific variation.

——

Half a month later.

Lianhai Center for Disease Control and Prevention, Emergency Office.

Gu Yanan is writing a summary report on the resurgence of the filariasis epidemic.

Fairy Lake in Yuntai County, Lianhai City belongs to the old epidemic area of filariasis.

In the sixties and seventies of the last century, Malayan filariasis was endemic here.

After decades of control, filariasis was declared eradicated in 2001.

However, Malary filariasis has an intermediate host and can persist in nature for a long time, with cats as a storage host and mosquitoes as a vector in the villages around Fairy Lake.

Sha Hongyu, a villager in Shajia Village, next to Fairy Lake, has a cat at home, the cat carries filarial worms in its body, and there are a large number of mosquitoes breeding in the surrounding environment of the house.

This is also the case in Shajia Village and other villagers in Taipingzhuang.

The presence of host cats, and vector mosquitoes, has led to a resurgence of filariasis in the two villages around Fairy Lake.

Through the mosquito control campaign, the Breto index around Fairy Lake was reduced to a safe range.

After treatment, the patient gradually improved, and the content of microfilariae in patients with microfilariaemia was gradually decreasing by taking imamethazine salts.

In the coming period, long-term monitoring of microfilariae and mosquitoes in the surrounding villages around Fairy Lake will be carried out.
