【Harry Potter: The Strongest Senior】【】

St. Mungo's attending therapist Hibercrate Smethyke and trainee therapist Augustus Pye arrived at Hogwarts early in the morning.

"Go directly to the classroom for testing." Dumbledore led the two therapists to the first floor.

Astoria's class was taking Transfiguration class with Gryffindor, and Sean, an idler patrolling between classes, also followed curiously.

Slytherin and Gryffindor were in Professor McGonagall's Transfiguration class, and when Dumbledore came to the door, Professor McGonagall stopped the lecture.

"The situation is not very optimistic. It's just that after a weekend, the symptoms among the students have increased." Professor McGonagall whispered in Dumbledore's ear.

Only two days later, students with magical disturbances sprung up like mushrooms after rain, accompanied by symptoms such as listlessness and loss of appetite.

Even Draco, who was lying on the hospital bed yesterday and happily eating the snacks sent by his classmates, is in a state of staying up all night today, with drooping eyelids and unable to cheer up.

Two-thirds of the students in the Astoria class have such symptoms, and the Gryffindor students who are in the big class together seem to be infected.

Before entering the classroom, the two therapists from St. Mungo put on protective measures outside, with masks and gloves tightly fitted.

After the two came in, the attending therapist Hibercrate Smethek reminded.

"It's best for you to wear masks and gloves. Look at it, even if it's not Bath syndrome, it's another contagious disease. But don't be afraid if it's Bath syndrome. It's not the fourteenth century, and the antidote is very convenient to prepare."

Dumbledore and Professor McGonagall took the masks from the trainee therapist, trainee therapist Augustus Pye, and the students below were chattering and chattering.

"Quiet." Dumbledore's resonant voice filled the classroom, "Students, don't be nervous. Some of you may be sick and need to be tested."

The students were even more nervous now. They felt that their condition was a bit wrong these two days, but after all, they were still young and had no serious symptoms, so everyone didn't care.

"Ginny, I'm scared," said a girl from Gryffindor on the left side of the classroom.

"It's okay, Dumbledore is here, don't be nervous." Ginny comforted.

In the classroom, 10 Slytherin students and 12 Gryffindor students lined up one by one, standing on both sides of the podium, Smethyk was in charge of Gryffindor, and intern Pai was in charge of Slytherin.

"Spread your hands, relax, just take a drop of blood from your middle finger," Pai said.

Astoria held out her right hand, and Pai dabbed alcohol on her **** with a cotton swab, then pricked her **** with a thin needle quickly and deftly.

"Come on, squeeze it and let the blood drip in." Pai said, holding up the ampoule.

Astoria squeezed a drop of blood into the ampoule, and Pai immediately drew a drop of light yellow liquid from a vial of about 50 milliliters with a dropper, and dropped it into Astoria's ampoule. Then put the lid on.

"Okay, what's your name?" Pai asked.

"Astoria Greengrass."

With a wave of Pai's finger, a quill flew out from his breast pocket. Under his control, the quill wrote Astoria's name on the ampoule.

The ink in this quill is also custom-made by St. Mungo's Hospital. This ink can write clearly on glass, just like writing on paper.

Fifteen minutes later, the 22 students had their blood taken. At the request of the therapist Smethyk, Professor McGonagall and Dumbledore also took blood.

"Sean, you come too." Dumbledore shouted to Sean outside the window.

Sean and Astoria have been in contact many times, so they really should be tested.

"Sir, if it's Bath, how is it transmitted?" Sean asked.

Smethiek said, "Transmission through physical contact, indirect contact, and items touched by the patient, the germs can survive outside the body for ten to twenty minutes."

"There should be no direct physical contact, but indirect contact?" Sean recalled, there must be indirect contact.

"Professor, does Draco's class also need to be tested?" Sean said.

"Well, let's go now."

The bottle of pale yellow liquid is a special test agent for Bath disease. After the blood with Bath bacteria encounters the test reagent, the result will be available in about an hour. The blood turns brown, indicating that it has been infected.

Students who have been tested will remain in the classroom until the results are available.

After 1 hour and 20 minutes, the results of the blood reaction came out. Unfortunately, all the blood samples from the Astoria class, Ginny class, and Dracoban were brown.

Even Harry's class, who occasionally attends classes with Draco's class, has one-third of them infected.

A total of four classes were tested, and the infection rate reached 90%.

"My God, it's over. According to this infection rate, the members of Ouroboros must have been recruited. In the whole school, at least one-third of the people will be infected." Sean estimated the number in his heart. Fortunately, he himself Shown to be uninfected.

However, Sean had learned about Bath Syndrome from the trainee therapist Paina just now. It was the first large-scale outbreak in the 14th century, sweeping the entire Europe. At that time, no antidote had been developed, so the fatality rate reached 8%.

In the following centuries, Bath syndrome also occurred on a small scale in various European countries, but with the development of antidotes, the fatality rate dropped to 1%.

"No one has died from Bath disease now, and the antidote is also being perfected. Three years ago, a wizard village in Germany was also infected with Bath disease. The control and treatment were timely, and all patients recovered in half a month." Pai said. Said.

"But the infection rate." Pai muttered.

"What?" Sean asked.

"It's okay. After everyone in the school finishes the test, St. Mungo can prepare the antidote and it will be under control."

Sean thought that this was similar to the flu in Muggle society. He experienced a flu outbreak when he was a child, and the school was closed to let them go home. It will be fine after a while, and it is not a big problem.

There are 396 students in the school, plus 20 faculty members, 9 house elves, and two therapists, all of which were not tested until three o'clock in the afternoon.

At around 4:30, the results of all the blood samples came out, and the number of infections surprised even the therapist Smethek.

"There are 270 people!" It's more than half of the number of people in Hogwarts, and the infection rate has exceeded that when Bath's disease first broke out in the fourteenth century.

Many of these students may have been infected only in the last few days, and the initial symptoms did not appear.

"Director, this infection rate is not so high in previous cases in other countries, could it be?" Pai hesitated to speak.

"You want to say that the germs evolved and mutated, and spread through the air~lightnovelpub.net~ Smethek also thought of this possibility.

If it was transmitted through the air, it would be terrible. Hogwarts had to be sealed off immediately, and even the students who went to Hogsmeade on weekends had to investigate their whereabouts.

When Smethyk told Dumbledore about this conjecture, Old Deng's face darkened. He didn't hide it from teachers and students, and immediately informed the whole school.

"For the sake of safety and to facilitate centralized treatment, the infected teachers and students live in the auditorium, and other students stay in the dormitories. Hogwarts will suspend classes from today."

The infected students below were in an uproar. They had never experienced such a large-scale infectious disease. The students with poor mental quality couldn't control their emotions and cried.

"Quiet, listen to me, there is an effective cure for Bath Syndrome. St. Mungo's therapists will heal everyone as soon as possible, so that Hogwarts can resume classes." Dumbledore used amplifying spells across the school Said loudly.

Sean figured it out, "Voldemort let Astoria come back because he planted a biochemical weapon."

But besides the high infection rate of Bath syndrome, wizards cannot cast spells unless the symptoms are very serious in the later stage. The early symptoms are still relatively mild, and the fatality rate is currently zero.

"Voldemort is knocking the mountain and shaking the tiger?" Sean thought to himself.

Except for Sean, everyone else in Ouroboros was recruited, and Chris came into contact with Cassius again. Except for Hermione, the other two of Harry's trio lived in the auditorium.

The "Evening Prophet" that night reported the outbreak of Bath syndrome at Hogwarts for the first time, and the evening paper would only be reprinted and issued when major events occurred.

And Dumbledore seemed to be afraid that Voldemort would take advantage of it, so he contacted Fudge in the afternoon and sent five more Aurors to protect Hogwarts.
