病原体变异监测

通过GenSpectrum LAPIS API查询实时病原体基因组监测数据,查找当前流行的病毒谱系、其增长速度及携带的突变。

病原体变异监测 是什么?

该技能用于回答依赖病原体种群当前状态的问题,而非记忆中的事实。它通过脚本与LAPIS实例交互,实时获取谱系流行率、突变谱、报告延迟等监测数据。支持多种病原体(如SARS-CoV-2、H5N1、流感、RSV等),并自动适配各实例的字段名和日期格式。技能核心是避免使用过时或已撤销的谱系名称,确保所有数据来自当天的实时数据库实例。陷阱表详细列出了常见错误(如谱系索引、字段名差异、重组体处理等),帮助用户避免生成静默错误的结果。输出需包含实例、数据版本、筛选条件和时间窗口,以支持结果复现。

病原体变异监测 是做什么的?

何时使用

任何答案依赖于病原体种群当前状态时:哪些谱系在流行,某个谱系是否在增长,谱系名称当前的含义,或检测靶标是否仍然匹配。

规则

绝不要凭记忆陈述当前流行的内容,也绝不要凭记忆写出谱系名称。

同时会出现三个问题,只有第一个是普通的知识截止问题:

  1. 名称在训练之后出现。 Pango指定列表包含超过6,200个名称,且不断增长。
  2. 命名法是活的数据结构,而非约定。 XFG是一个重组株,只能通过alias_key.json解析;PQ.17解别名为XDV.1.5.1.1.8.1.17。这两种扩展都无法通过推理得出——映射是一个不断变化的文件。
  3. 已有知识会被撤销,而不仅仅是过时。 当前lineage_notes.txt中有294个名称被撤销或重新指定。PC.2现在是LF.7.9;XFG.20被完全撤销。记住的谱系事实不仅可能陈旧,而且可能是错误的。

该技能报告的每个数字都是实时实例返回的计数,并带有其数据版本戳。

范围

面向研究的监测数据分析。此技能描述的是已收集并提交的序列;它不产生临床解释、疫情响应建议或公共卫生指导,序列计数不等于病例计数。

实例

一个API形态覆盖所有病原体。--instance指定已验证的部署;--base-url到达任何其他LAPIS实例。

实例主机谱系列已索引
sars-cov-2lapis.cov-spectrum.org(开放GenBank数据)pangoLineage是
h5n1, h3n2, h1n1pdm, influenza-alapis.genspectrum.orgclade否
rsv-a, rsv-b, mpox, measles, dengue, west-nile, hmpv, ebola-zaire, ebola-sudan, cchflapis.pathoplexus.org因实例而异因实例而异

字段名因实例而异,绝不假设。 每个脚本在运行时读取/sample/databaseConfig,并从实例实际声明的列中选取收集日期、提交日期和谱系列。dateFrom=在SARS-CoV-2上是正确的,而在H5N1上则会返回400错误,因为其收集日期是sampleCollectionDateRangeLower。

脚本

cd skills/pathogen-variant-surveillance/scripts
脚本回答的问题
resolve_lineage.py这个名称还存在吗?它扩展成什么?它从何而来?
lineage_prevalence.py这个谱系在每周的序列中占多大比例?它正在增长吗?
mutation_profile.py它携带哪些突变?与另一个谱系相比有何不同?
reporting_lag.py数据需要回溯多远才能可靠使用?

所有四个脚本都接受--format table|tsv|json,并将来源信息(实例、数据版本、已解析的字段名、筛选条件)打印到stderr,因此> out.tsv可以保持数据干净,同时来源信息可见。

从数据出发,而非记忆中的列表

# 无名称:发现窗口内实际流行的内容
python3 lineage_prevalence.py --top 5 --where country=USA --weeks 12

注:发现了窗口内最常见的5个pangoLineage值: XFG.1.1, XFG.23.1.3, PY.1.1.1, XFJ.3.1.2, PQ.17

这是回答“目前流行什么”的正确第一个命令。预先命名谱系意味着你假设已经知道哪些谱系重要,而本技能存在的目的正是消除这种假设。

使用名称前先检查

python3 resolve_lineage.py XFG.23.1.3 PQ.17 PC.2 NOTALINEAGE
查询        状态       解别名                           父谱系    重组来源                 后代  序列数  详情
XFG.23.1.3  当前       XFG.23.1.3                       XFG.23.1  LF.7+LP.8.1.2           6     317      S:A1174V,位于C29137T分支
PQ.17       当前       XDV.1.5.1.1.8.1.17               NB.1.8.1                    23     931      XDV.1.5.1.1.8.1.17的别名
PC.2        已撤销     B.1.1.529.2.86.1.1.16.1.7.2.1.2  LF.7.2.1                    4      25       现为LF.7.9;重新指定为LF.7.9
NOTALINEAGE 未知       NOTALINEAGE                                                         0      n/a     活命名法中没有该名称

(详情已精简;每个真实行还会引用其谱系提案来源。)

如果任何名称被撤销或未知,退出码为1,因此它可作为稿件谱系列表的门控。注意PC.2:上游已撤销,但仍有25条序列携带该标签,因为实例的指定滞后于命名。这两个事实都是真实的,且都很重要。

流行率和增长

python3 lineage_prevalence.py "XFG.1.1*" "XFJ*" --where country=USA --weeks 16 --growth
谱系       周         n  总数  比例     置信下限  置信上限  覆盖度
XFG.1.1*   2026-05-04  42  80    0.5250   0.4170    0.6308    正常
XFG.1.1*   2026-06-15  3   49    0.0612   0.0210    0.1652    正常
XFG.1.1*   2026-06-29  1   30    0.0333   0.0059    0.1667    低
XFG.1.1*   2026-07-13  0   0                                   低

比例带有Wilson置信区间,因为监测周数据量较小。分母尚未填满的周被标记为低,并排除在增长拟合之外,除非使用--include-incomplete。

时间窗口会扩展为完整的ISO周,并在扩展时明确说明。从周中开始的时间窗口会给出覆盖三天的第一行和覆盖四天的最后一行,两者与之间的完整周都不可比。

--growth报告对数几率对时间的加权最小二乘斜率。它是描述性的:它吸收了谁在测序、在哪里测序以及他们报告速度的所有变化。它不是适应性或传播性的估计。对于观测数过少的谱系,不会打印斜率——参见陷阱表了解为什么存在这个保护措施。

突变以及检测是否仍然匹配

python3 mutation_profile.py "XFJ*" --versus "XFG*" --gene S --since 2026-01-01
突变      基因  位置  判定    比例_a  比例_b  n_a  n_b
S:L441R    S     441   获得    1.000   0.000   66   0
S:A475V    S     475   获得    1.000   0.000   68   0
S:K444R    S     444   丢失    0.000   0.996   0    5031
S:Q493E    S     493   丢失    0.000   0.998   0    5359

在分段基因组上同样有效——例如--instance h5n1 --gene HA或--gene seg4。对于引物和探针相关问题使用--nucleotide,因为此时密码子不是相关的单位。

决定回溯多远的数据才可靠

python3 reporting_lag.py --where country=USA
延迟天数  平均完成度  最小完成度  最大完成度  队列数
14        0.456       0.332       0.557       6
30        0.677       0.580       0.822       6
60        0.868       0.802       0.949       6
90        0.939       0.916       1.000       6

90天内90%的队列已完成。信任至2026-04-28的收集日期;之后的数据视为临时数据。

在引用任何近期流行率之前运行此命令。该曲线因病原体和国家而异:在H5N1上,同样测量在14天时返回0%完成度,30天时为15%,因此“当前”H5N1图景实际上有两个月的盲区。

导致静默错误答案的陷阱

所有陷阱均于2026-07-27通过实时API验证。这就是为什么此技能提供脚本而非配方的理由;完整细节见references/lapis-api.md。

陷阱后果
裸谱系名称排除其后代pangoLineage=XFG返回4条序列;XFG*返回640条
尾随的*需要谱系索引在H5N1上clade=2.3.4.4b返回62,413条,而clade=2.3.4.4b*返回0——相同语法,相反含义
字段名因实例而异dateFrom在H5N1上返回400错误;收集日期是sampleCollectionDateRangeLower
仅date类型的字段支持范围H5N1将sampleCollectionDate类型化为字符串,因此它根本没有From/To键
最近几周不是流行样本它们只是报告最快者的样本;美国队列中仅有29%在7天内到达
LAPIS对重组株的根处理询问XFG的父谱系返回空;只有alias_key.json记录了XFG = LF.7 + LP.8.1.2
已撤销名称在数据中持续存在PC.2在上游被重新指定为LF.7.9,而序列仍携带PC.2
未知名称仅在索引时大声失败已索引列对拼写错误返回400错误;未索引列回答0
突变比例是针对覆盖度而非所有匹配序列一个覆盖度差的位点可能在很少的读段上显示1.000
/sample/aggregated拒绝limit/orderBy结果没有固有排序;在客户端排序

报告结果

说明实例、数据版本、筛选条件和时间窗口——没有这些,流行率数据无法复现,因为底层数据库每日都在变化。同时给出计数和比例,引用置信区间,并明确说明何时窗口太新而无法支持估计。“过去六周无可靠估计”是一个合法且通常是正确的答案。

anndata

Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.

arbor

Autonomously improve a real artifact (code, training recipe, agent harness, data pipeline, prompt) against an objective and an evaluator, using Hypothesis Tree Refinement (HTR) from the Arbor paper. Use this whenever someone wants to iteratively optimize something over many experiments without overfitting — e.g.

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bioservices

Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
