Gu Yanan smiled and comforted his brother and said, "It is our disease control responsibility to go to the scene for the first time, and it takes night time to collect blood for filariasis screening, so it's just right to rush over now." ”

Old Zhou also comforted Gu Jiashu, "Doctor Gu, don't worry, we will take care of Director Gu." Director Gu is responsible for directing, knocking on doors to collect blood, and people from county disease control are going to do it. ”

It's okay if it's not comforting, but when Zhou Lao comforted him like this, Gu Jiashu was even more worried, and he even had to go door to door in the middle of the night to knock on the door, which sounded unreliable and tiring.

——

2:30 p.m.

The Municipal Disease Control and Emergency Response Team drove the on-site flow shunting to Yuntai County.

Because it was suspected that the filariasis epidemic was re-incurring, several members of the emergency response team were very interested in not only worrying, so they all asked to go to the scene.

Considering that the scene had to collect blood from the villagers and the surrounding domestic and wild mammals, the whole flow investigation work was complicated, and although there were people from the county disease control and control, there was still a shortage of manpower, so Gu Yanan brought the entire emergency response team with him.

On the driving shunting car, several people from the emergency team chattered around Zhou Lao.

Wang smiled: "Sister Yanan, are we really going to Shajia Village to knock on doors and collect blood tonight?" ”

Gu Yanan: "Well, this is the work experience of Zhou Lao and them in the past, this time the situation is urgent, we can discuss with the village cadres, mobilize the villagers to gather in a certain location in the village at about 10 o'clock in the evening, so that the disease control personnel can collect blood in a centralized manner, so as to facilitate the control of the number of people and improve work efficiency." ”

"Why do you want to take blood at night?" Goofy asked.

Zhou Lao patted Gao Fei's shoulder, "Young man, at first glance, the basic knowledge is not good, the larvae of filarial worms - microfilariae, have the characteristics of diurnal and nocturnal, stay in the pulmonary capillaries during the day, and only appear in the peripheral blood at night, so blood collection must be carried out from 8 pm to 2 am on the second day, in order to improve the test positive rate, we generally collect blood after 10 pm." ”

Lu Li: "Didn't my country announce the elimination of filariasis a long time ago?" Is this really a resurgence of the filariasis epidemic? ”

"There is a possibility of a resurgence of smallpox, let alone filariasis, which has only been declared eliminated but not eradicated." Wang Xiaoxiao said with emotion.

Xiao Chu: "Teacher Zhou, I am very curious about your experience in filariasis prevention and control at that time, our emergency team has not experienced the filariasis epidemic except for you, can you tell us about the situation at that time." ”

Although Xiao Chu's question was gossipy, he was full of curiosity, and Zhou Lao was very willing to tell young people about his past experiences, so he talked eloquently.

"At that time, the CDC had not changed its name to the epidemic prevention station, and the most difficult thing for grassroots epidemic prevention was the winter screening for filariasis.

Although filariasis spreads in the hot weather in summer and autumn, the general survey of filariasis is selected in winter, mainly because there are various infectious diseases to be prevented and treated in other seasons, such as encephalopathy, measles, and influenza in winter and spring, cholera, typhoid, hepatitis A, malaria, and leptospirosis in summer and autumn, and hemorrhagic fever in autumn and winter.

At that time, I was still a young epidemic prevention worker who had just graduated, and I followed the teacher to go to various counties and districts in Lianhai City to conduct a census, regardless of the cold, rain or snow, I had to collect earlobe blood from house to house.

At that time, the census personnel brought their own bedding, often laid straw to sleep, could not rest for a few hours, and had to get up to collect blood and peel pieces for dyeing and static examination and washing, the workload was particularly large, generally 1~2 days to check a brigade, a commune to check for more than a month, day after day, poor food, poor housing, bad weather, overload of workload, sometimes a county is more than a month.

I remember that after 1978, on the basis of repeated investigation and treatment, Lianhai City adopted the national administration of marine raw medicine salt to prevent filariasis in the filariasis epidemic area, that is, the marine raw pills were crushed, mixed into table salt according to the prescribed proportion, and provided to the residents for consumption, and the corresponding course of treatment was taken according to the epidemic degree of filariasis.

In this process, the personnel of the epidemic prevention station must go to the commune to supervise the salt mixing work to ensure the quality of the medicinal salt.

The effectiveness of these measures in the control of filariasis was so remarkable that after years of monitoring, Lianhai City declared in 2001 that it had met the criteria for the elimination of filariasis.

Since then, there have been no new cases of local filariasis reported in Lianhai. ”

Zhou Lao said very plainly, but several members of the emergency team could feel the hardship of the work at that time, Wang Xiaoxiao sighed, "Wow, I didn't expect the prevention and control of filariasis to be like this, adding preventive drugs to the edible salt of residents is the same as the principle of adding iodine to edible salt to prevent iodine deficiency now." ”

"Although the diseases prevented are different, the means are the same, and the results are all very good."

Xiao Chu sighed, "I didn't expect the previous disease control work to be so hard. ”

Zhou Lao, "I didn't feel bitter when I was young, but there was such a limerick poem popular in the epidemic prevention circle: There are women who do not marry epidemic prevention men, keep empty houses all year round, and one day go home and leave a pile of dirty clothes." ”

Several members of the emergency team laughed in unison, and Wang Xiaoxiao even quipped, "It was really not easy for Zhou Lao to marry a wife at that time." ”

"It's not easy, I know your sister-in-law Zhou, or because of a fate in malaria prevention and control."

"Something to do with epidemic prevention? Teacher Zhou will tell us about it. ”

"If you want to talk about this fate, we have to start with the malaria epidemic in our Lianhai City.

In the early 1970s, there was a large-scale outbreak of malaria in Lianhai City, the incidence of malaria in Yuntai County was close to 30%, and the local villages were as high as more than 40%, the situation was grim, at that time the relevant departments adopted the enumeration prevention and control strategy, and in 1974~1976, the policy of two full and two repetition was adopted, that is, the telogen period was completely cured, the epidemic season was prevented by the whole people, and the children with malaria history were cleaned up and retreated before the epidemic season, and the current patients were cleaned up and reproduced.

After 1977, the use of both comprehensive and double recovery was stopped, and the strategy of one prevention and three treatment of peak blood pressure was adopted, that is, mosquito prevention and control, radical treatment in the telogen period, treatment of patients with existing symptoms, investigation and treatment of fever patients, and comprehensive measures to prevent the peak of drug pressure in the epidemic season.

By the end of the seventies, the malaria incidence rate in Lianhai City dropped to 0.90 per cent, and since then, the malaria incidence rate in Lianhai City has steadily decreased year by year.

I still remember that at that time, the telogen telogen phase of malaria was used to treat the whole population with 8-day treatment of apraquine, and the drug was taken for people from 3 years old to 70 years old, except for pregnant women, of course.

Due to the large number of people taking medicine, the process is long, in order to ensure the quality of the drug work, all the business personnel of the county health and epidemic prevention station are dispatched, each person is responsible for a commune, regardless of whether the weather is sunny or rainy, the staff of the epidemic prevention station must visit the homes of the major teams every day to check the implementation of the drug work.

From the beginning of the preparation of the medication to the end of the inspection and acceptance, the doctors at the county health and epidemic prevention station must work in the commune where they are stationed for about a month. That's when I met your sister-in-law Zhou. ”

"Oh, it turned out to be the flower of love that bloomed from revolutionary friendship."

Wang Xiaoxiao: "Old Zhou, now there are no local malaria cases in Haishi, your malaria prevention and control was a key task in the spring at that time, in addition to malaria prevention and control, is there anything else to do in the spring?" ”
