危。
凡发热一日，忽然密集发出，形态像蚕种一样，颜色灰白且稠密，身体发热、腹部胀满，腹泻和口渴不止，头部温热而脚部寒冷，以及痘色紫黑干枯的，预后不良。
初起发热时即见痘点出现在太阳经、太阴经循行部位，如额角、发际、印堂、司空、天庭、方广等区域，痘色红紫，眼睛发红、嘴唇干裂，喉间痰鸣、声音嘶哑的，这是气滞血凝，毒邪妄犯阳位所致，预后不良。
嘴唇上出现痘疮的，预后不良。
牙床上出现痘疮的，预后不良。
初起时痘顶完全不起，形状像水泡或火烧过的样子，这是气血两败，必然在九日后因瘙痒塌陷而死。
痘已发出，但热退后又反复出痘的，预后不良。
连片肌肉呈现红紫色，面部皮肤粗糙如桔皮，分不清肉与地的界限（指痘根与周围组织无界限），预后不良。
痘疹只出现在腰部以下，腰部以上没有的，预后不良。
痘色白而皮薄，光滑润泽容易破溃，痘根完全没有红色，三到五天就长得像菜豆那么大，这种痘绝对不会化脓，久了变成一包清水，擦破必死。不要因为看起来好看，就胡乱使用攻下药。
初出时痘顶凹陷，中间有黑点，像针孔一样的，预后不良。
周身痘疹分布匀称，唯独口唇处细密拥挤，名叫“锁口”，必须防备在九十天左右，因不进食、发热而死。
有的痘疹独多集中在三仓部位，多的称为“缦胸”，必须防备在九十天左右，出现失声、腹痛、咬牙等症状而危重。
有的痘疹独多集中在肩背部，名叫“攀肩”。足底的涌泉穴和肩上的肩井穴，是暗水潜行的通道。凡是津液滋润布散于皮肤之内的，都是依靠这些井泉之水，而以肾为源头。毒邪盛于此地，水道断绝了。而且五脏都依附于背部，背上痘疹太密，脏气受损。所以必须防备因发热、失声、烦躁口渴而死。
起势不多，痘根肥润，颜色青白，热盛神志昏沉的，名叫“反脚”，三到五天内必死。
初起先在天庭、方广、太阳等处，看见一粒痘标突起，光亮好看，片刻后又陷没下去的，这名叫“贼标”，就像贼想要攻破城池，先用奸细试探一样，是决死的病症。
初起发热时腰痛，等到报点（痘点显现）时仍然剧烈疼痛不止，痘标像蚕种，面色赤红、气粗，烦躁昏乱的，主病在五到六天，必然口中大臭，身上出现紫黑斑点，或者口唇青黑，舌上生疔疮而死。
阴囊两边先见痘点的，后来必然黑陷。用灯火照看，如果在天庭、百会、巨关、人迎等穴位处，有红点斑纹在皮肤里面的，发出的痘疹必然严重。
发热未透达时就报点见标，随后又隐没不见，接着又出来又隐没的，叫做“弄标”。因为痘疹痛热透达，肌肤通畅自然容易发出；现在热不透，则地皮未热，所以隐没又出现，出现又隐没，这是气血衰弱得很厉害，无力发泄的缘故。必然难以治疗。
痘疹都极其稠密，而疹子又不先消退的，这名叫“狩痘”，预后不良。
痘未发出而身上有紫红色斑，或有几点黑斑，鼻出血、神志昏沉，身体发热烦闷的，在三五天内死亡。
手足面部都出了痘，但身体发热烦躁不退，唯独耳前、耳后没有痘的，是凶险的症候。只有周身稀少，红活滋润，痘粒分明，上下分布均匀的，才无害。
痘发到三四天，脚酸不能站立的，凶险。
出痘时，胡言乱语，如见鬼怪，喜欢喝冷水，斑疹先从腰眼处起来的，预后不良。
发青斑、黑斑像痣一样，以及肌肉有成块青黑的，立即死亡。
肌肉内部感觉像被杖击打一样疼痛的，预后不良。
初起身上有斑点，嘴唇崩裂或肿胀，口出臭气的，这是胃烂发斑，预后不良。
舌头卷缩、阴囊收缩的，死亡。
凡是先发无名肿毒而后出痘的，十有九个死亡。
初出痘时呕吐腹泻不止，蛔虫从口鼻大便中排出，且不进饮食的，死亡。
遍身紫泡，刺破流出黑血的，死亡。
痘疹稠密陷伏、烦躁、狂叫，口中腥臭冲人的，这是邪火煎熬，导致肺烂胃败。必然变为失声、干呕、喘促，七天后死亡，《内经》说：肺绝者，七日死。
痘出顶陷，而脐窝内有疮的，百无一救，这是肾经痘，主寒战、咬牙而死。
痘出后胡言乱语不止，昏睡不食，手脚冰冷的，死亡。
起势拖沓，面色多青而不热的，危险。
If fever lasts for one day and then suddenly erupts densely, resembling silkworm eggs, with a grayish-white color and dense distribution, accompanied by body heat, abdominal distension, incessant diarrhea and thirst, warmth of the head but coldness of the feet, or if the pustules are purple-black and dry/withered, the prognosis is fatal.
If spots appear immediately upon initial fever in the regions of the Taiyang (Greater Yang) and Taiyin (Lesser Yin) meridians, such as the temporal angle, hairline, Yintang (between eyebrows), Sikong, Tianting (forehead center), and Fangguang areas, with red-purple coloration, red eyes, cracked lips, phlegm rattle in the throat, and hoarseness, this indicates Qi stagnation and Blood coagulation, with pathogenic factors recklessly invading Yang positions; the prognosis is poor.
Pustules appearing on the lips indicate a poor prognosis.
Pustules appearing on the gums indicate a poor prognosis.
If upon onset the pustule tops do not rise at all, resembling water blisters or burns, this signifies exhaustion of both Qi and Blood; death will inevitably occur after nine days due to itching and collapse.
If pustules have erupted but fever recurs repeatedly after subsiding, the prognosis is poor.
If the flesh appears as a continuous patch of red-purple, the face resembles an orange peel, and there is no distinction between the pustule base and surrounding tissue, the prognosis is fatal.
Pustules appearing only below the waist, with none above the waist, indicate a poor prognosis.
If pustules are white with thin skin, smooth and moist, easily ruptured, lacking any redness at the base, and grow to the size of a vegetable bean within three to five days, these pustules will absolutely not suppurate. Later, they become sacs of clear fluid; rupture leads to certain death. Do not administer purgative medicines rashly just because they look appealing.
If upon eruption the top is depressed with a black dot in the center like a needle puncture, the prognosis is poor.
If the body's pustules are evenly distributed except for being densely clustered around the mouth, named "Locking the Mouth," one must beware of death from starvation and fever around the 90th day.
If pustules are predominantly concentrated in the "Three Granaries" area, termed "Man Chest," one must beware of critical condition around the 90th day, characterized by loss of voice, abdominal pain, and teeth grinding.
If pustules are predominantly concentrated on the shoulders and back, named "Climbing Shoulders." The Yongquan acupoint on the soles and Jianjing acupoint on the shoulders are pathways for hidden water flow. All fluids moistening the skin rely on these spring waters, originating from the Kidney. When pathogenic toxins are excessive here, the water pathways are cut off. Since all Zang organs attach to the back, excessive density on the back injures Zang Qi. One must beware of death from fever, loss of voice, irritability, and extreme thirst.
If the onset is sparse, the base is plump and moist, the color is greenish-white, accompanied by high fever and coma, it is named "Reverse Foot"; death will occur within three to five days.
If initially, a single spot appears prominently and brightly on the Tianting, Fangguang, or Taiyang areas, but sinks and disappears shortly after, this is named "Thief Spot," analogous to spies scouting before a city siege; it is a definitive fatal sign.
If lower back pain occurs during initial fever, and severe pain persists when spots emerge, with spots resembling silkworm eggs, flushed face, coarse breathing, irritability, and confusion, death will likely occur on the fifth or sixth day, preceded by foul breath, purple-black macules on the body, cyanotic/black lips, and carbuncles on the tongue.
Jaundice caused by Stomach Heat, resembling orange color, accompanied by diarrhea, indicates a poor prognosis.
If pustules first appear on both sides of the scrotum, they will later turn black and sink. If red macules are visible beneath the skin at acupoints such as Tianting, Baihui, Jiguan, and Renying when illuminated by fire, the resulting eruption will be severe.
If spots appear while fever is not yet fully resolved, then disappear, then reappear and disappear again, this is called "Playing with Spots." When toxin-heat penetrates thoroughly, skin and muscles are unobstructed, facilitating easy eruption. Here, heat does not penetrate, so the "ground" is not warm, causing hiding and re-emergence. This indicates severe depletion of Qi and Blood, lacking strength to vent pathogens; treatment will be difficult.
If both pox and rash are extremely dense, and the rash does not resolve first, this is named "Hunting Pox," indicating a poor prognosis.
If purple-red macules or several black macules appear on the body before pox eruption, accompanied by epistaxis, lethargy, body heat, and restlessness, death will occur within three to five days.
If hands, feet, and face have erupted, but body heat and irritability persist, and specifically the ear lobes and back of ears lack eruptions, this is a ominous sign. Only if eruptions are sparse, vibrant red, moist, distinct, and evenly distributed throughout the body are harmless.
If legs ache and standing becomes impossible on the third or fourth day of eruption, it is ominous.
Delirium, hallucinations of seeing ghosts, craving cold water, and macules starting from the lumbar region during eruption indicate a poor prognosis.
Green or black macules resembling moles, or patches of green-black muscle tissue, lead to immediate death.
Sensation in muscles as if beaten by a staff indicates a poor prognosis.
Initial appearance of macules, bursting/cracked or swollen lips, and foul breath indicate "Stomach Rot Macules," which is untreatable.
Tongue retraction and scrotal contraction indicate death.
Eruption of pox following an initial unnamed swelling/toxin results in death in nine out of ten cases.
Incessant vomiting and diarrhea upon initial eruption, expulsion of roundworms from mouth/nose/stool, and refusal to eat indicate death.
Whole-body purple blisters that release black blood upon puncture indicate death.
Dense, sunken, irritable, screaming pox with a fishy odor emanating from the mouth indicates pathogenic fire roasting, leading to lung rot and stomach failure. It will progress to loss of voice, dry retching, and panting, causing death in seven days. The Classic states: Lung exhaustion leads to death in seven days.
Sunken pox tops with sores in the umbilical fossa are incurable (one in a hundred survives); this is Kidney Meridian Pox, leading to death via chills and teeth grinding.
Unceasing delirium, lethargy, anorexia, and cold extremities following eruption indicate death.
Lingering onset, predominantly blue complexion without heat indicates a critical condition.
