Sexual Assault and STI Transmission in Taiwan: 7 Risks

Sexual Assault and STI Transmission in Taiwan can expose a suspect to several overlapping criminal investigations, including sexual offenses, HIV-specific offenses, bodily injury, and—in narrowly defined cases—violations of communicable-disease legislation. However, these offenses do not arise automatically merely because a sexual encounter and a later infection are alleged. Prosecutors must separately prove the absence of consent, the suspect’s knowledge, the relevant conduct, medical causation, and the required criminal intent.

These cases are legally and medically complex. A sexual assault allegation does not itself prove that the accused knew of an infection, while a positive test result does not by itself establish who transmitted the infection or when transmission occurred. Each element must be supported by admissible evidence.

💡Chien Sheng International Law Office explains seven major legal risks, the evidence commonly examined during an investigation, and the rights available to both complainants and accused persons.

---

1. What Constitutes Sexual Assault Under Taiwan’s Criminal Code?

Article 221 of Taiwan’s Criminal Code applies when a person uses threats, violence, intimidation, hypnosis, or another method against another person’s will to engage in sexual intercourse. The offense is punishable by imprisonment for three to ten years.

The central issue is whether the sexual conduct occurred against the other person’s will. Investigators may examine:

• Messages and communications before and after the incident;
• The relationship between the parties;
• Statements made by both parties and relevant witnesses;
• Medical and forensic examination records;
• Surveillance footage, location records, or transportation records;
• Evidence of violence, threats, intoxication, drugs, or inability to resist;
• The conduct of the parties before, during, and after the alleged incident.

Consent must relate to the particular sexual activity at the relevant time. A prior romantic relationship, marriage, earlier consensual intimacy, or voluntarily entering a private location does not automatically establish consent to a later sexual act.

Article 222 provides aggravated penalties where an Article 221 offense involves specified circumstances, including an offense committed by two or more persons, an offense against a person under fourteen, the use of drugs, carrying a weapon, abuse, intrusion into a residence, or recording or distributing images of the victim. The statutory punishment is imprisonment for at least seven years.

📝The current provisions can be reviewed in the official Criminal Code of the Republic of China.

2. Sexual Conduct Involving Minors Requires a Separate Legal Analysis

The original draft incorrectly placed consensual sexual conduct involving persons under sixteen under Article 224. The relevant age-based provision is generally Article 227.

🔎Under Article 227:

• Sexual intercourse with a person under fourteen is punishable by three to ten years’ imprisonment.
• An indecent act involving a person under fourteen is punishable by six months to five years.
• Sexual intercourse with a person aged fourteen but under sixteen is punishable by up to seven years.
• An indecent act involving a person aged fourteen but under sixteen is punishable by up to three years.

➠These provisions may apply even when prosecutors do not allege violence or threats. If the sexual act was also against the minor’s will and the requirements of Articles 221 or 222 are established, the legal assessment may be substantially more serious.

Article 224, by contrast, concerns an indecent act committed through violence, threats, intimidation, hypnosis, or another method against the victim’s will. It is not the general age-of-consent provision.Age, consent, use of force, the parties’ relationship, and whether the accused held a position of authority must therefore be examined separately.

3. When Can Sexual Assault and STI Transmission in Taiwan Create Multiple Charges?

An allegation involving both non-consensual sexual conduct and infection may lead investigators to consider several legal routes:

1. Sexual offenses under Articles 221, 222, 224, 225, or 227 of the Criminal Code;
2. Article 21 of the HIV Infection Control and Rights Protection for People Living with HIV Act;
3. Article 62 of the Communicable Disease Control Act, but only where its narrowly defined statutory requirements apply;
4. Injury or serious-injury offenses under Articles 277 and 278 of the Criminal Code;
5. Civil claims for medical expenses, lost income, psychological harm, and other proven losses.

➠The presence of an infection does not automatically establish all of these offenses. The prosecution must identify the applicable statute and prove its individual elements.

For example, the evidence needed to establish non-consensual sexual intercourse differs from the evidence needed to prove that a person knowingly concealed an HIV-positive status and caused another person’s infection. Medical causation, timing, knowledge, and intent may become independent points of dispute.

4. Article 21 Specifically Addresses Certain HIV-Transmission Conduct

Article 21 of the HIV Infection Control and Rights Protection for People Living with HIV Act provides that a person who knowingly conceals their HIV-positive status and engages in unsafe sexual behavior or shares injection equipment, thereby causing another person to become infected, may be sentenced to five to twelve years’ imprisonment. Attempted offenses are also punishable.

This provision requires careful attention to several elements:

• The accused knew of their HIV-positive status;
• The accused knowingly concealed that status;
• The accused engaged in conduct falling within the legally defined scope of unsafe sexual behavior;
• The conduct caused the other person’s infection, or the facts satisfy the requirements for an attempt;
• The accused possessed the criminal intent required by law.

A positive HIV test alone does not prove these matters. Medical records, diagnosis notifications, treatment history, viral-load evidence, the timing and type of sexual contact, prior test results, and expert opinions may all be relevant.

The law must also be applied without stigmatizing people living with HIV. HIV status alone does not establish criminality, dangerousness, or responsibility for another person’s infection. The offense depends on proof of the statutory conduct, state of mind, and causal connection.

5. Article 62 of the Communicable Disease Control Act Does Not Automatically Apply to HIV

Article 62 of the Communicable Disease Control Act applies to a person who knows that they have a Category 1 or Category 5 communicable disease, or multidrug-resistant tuberculosis classified under Category 2, fails to comply with instructions issued by the competent authority, and consequently infects another person.

The penalty is imprisonment for up to three years, criminal detention, or a fine of up to NT$500,000.

Contrary to the original draft, HIV should not simply be described as a Category 1 communicable disease for purposes of this provision. HIV-related criminal liability is addressed specifically under the HIV legislation discussed above.

For another sexually transmitted infection, Article 62 applies only if:

• The disease falls within the classifications expressly covered by the article;
• The person knew of the infection;
• A competent authority had issued an applicable instruction;
• The person failed to comply with that instruction; and
• The failure caused another person’s infection.

Accordingly, Article 62 cannot be treated as a general criminal provision covering every instance of alleged STI transmission.

6. Can Transmitting an Infection Constitute Bodily Injury?

Article 277 of the Criminal Code punishes a person who causes injury to another person’s body or health. The statutory penalty is imprisonment for up to five years, short-term imprisonment, or a fine of up to NT$500,000.

⚠️An infection may constitute harm to health, but criminal responsibility still requires proof of the relevant mental state and causation. Investigators may need to determine:

• Whether the accused knew or suspected that they had the infection;
• Whether the conduct was intentional or merely negligent;
• Whether negligence is separately punishable under the applicable provision;
• Whether the complainant had another possible source of infection;
• Whether medical testing can reliably identify the likely transmission period;
• Whether the alleged conduct was capable of producing the particular infection;
• Whether the resulting condition satisfies the statutory definition of serious physical injury.

Article 277 also provides enhanced punishment where ordinary injury results in death or serious physical injury. Article 278 applies where a person intentionally causes serious physical injury.

The original draft’s reference to Article 279 as the general provision governing death or serious injury was inaccurate. Article 279 concerns injury committed in the heat of passion following legally adequate provocation; it is not the ordinary aggravated-result provision.Where death or serious injury results directly from a sexual offense under Articles 221, 222, 224, 224-1, or 225, Articles 226 and 226-1 may also require examination.

7. Multiple Allegations Do Not Mean That Every Sentence Is Automatically Added Together

When the same incident appears to satisfy several criminal provisions, the court must first determine the legal relationship between the offenses.

Under Article 55 of the Criminal Code, when one act constitutes several offenses, the court generally imposes the punishment for the most serious offense, subject to the statutory minimum applicable to the less serious offense. This is commonly referred to as ideal concurrence.

Where the accused committed several legally independent acts, separate offenses may be established. If the requirements for combined punishment are met, Article 51 provides that the court must separately pronounce the punishment for each offense and then determine an aggregate sentence. For multiple fixed-term prison sentences, the aggregate sentence must fall between the longest individual sentence and the total of the sentences, subject to a maximum of thirty years.

Therefore, it is inaccurate to say that sexual assault, HIV-related liability, and injury charges will always be mechanically accumulated. The result depends on:

• Whether there was one act or several distinct acts;
• The timing and nature of each act;
• Whether each offense protects a different legal interest;
• Whether one offense legally absorbs another;
• Whether the elements of every alleged offense are independently established;
• The court’s application of Articles 51 and 55.

A criminal defense lawyer must analyze both the factual timeline and the legal concurrence of offenses before estimating sentencing exposure.

8. What Evidence Is Critical in These Cases?

Cases involving alleged sexual assault and infection often depend on a combination of testimonial, medical, digital, and forensic evidence.

Important materials may include:

• Complete conversations rather than selected screenshots;
• Dating-app and social-media records;
• Call records and location data;
• Hotel, transportation, payment, or surveillance records;
• Hospital records and sexual-assault examination materials;
• Laboratory reports and historical STI or HIV test results;
• Prescription, treatment, and viral-load records;
• Evidence concerning barrier protection or other precautions;
• Expert opinions on incubation periods and possible transmission windows;
• Records showing what the accused knew and when that knowledge was obtained.

No party should delete messages, alter records, pressure witnesses, or attempt to coordinate statements. Preserving the original data, including timestamps and surrounding context, is more useful than producing isolated screenshots after a dispute arises.

Consent to sexual activity and knowledge of an infection are also separate questions. Evidence that a complainant agreed to sexual activity does not necessarily resolve whether infection-related information was concealed. Conversely, evidence concerning an infection does not by itself prove that the sexual activity occurred without consent.

9. What Should an Accused Person Do After Receiving a Police or Prosecutor’s Notice?

Being reported or summoned does not mean that guilt has been established. However, sexual-offense investigations carry serious consequences and should not be treated as an informal conversation.

Before questioning, a suspect should:

• Confirm the alleged offense and procedural status;
• Preserve all communications, medical records, and electronic data;
• Avoid contacting the complainant to demand withdrawal or an explanation;
• Avoid posting accusations or identifiable information online;
• Prepare an accurate timeline with legal counsel;
• Answer only according to actual memory and avoid guessing;
• Review the written interview record carefully before signing.

Under Article 95 of the Code of Criminal Procedure, an accused person must be informed of the suspected offenses, the right to remain silent, the right to counsel, and the right to request the investigation of favorable evidence.Exercising the right to counsel is not an admission of guilt. It enables the accused to understand the accusation, avoid speculative statements, and present relevant evidence in an organized and lawful manner.

10. What Should a Victim Do After an Assault or Suspected Exposure?

The first priorities are personal safety and medical care. A victim may seek emergency treatment, STI testing, preventive medical advice, psychological assistance, and forensic evidence collection. Medical professionals should determine which examinations and treatments are appropriate and time-sensitive.

Where possible, the victim should preserve:

• Clothing and relevant personal items;
• Messages, call records, photographs, and location information;
• Medical documents and test results;
• The identity of anyone informed shortly after the event;
• Receipts for treatment, counseling, transportation, and lost income.

Under Taiwan’s Sexual Assault Crime Prevention Act, medical institutions generally may not refuse treatment or a diagnosis certificate without justification. The Act also provides privacy protections, rules for medical examination and evidence collection, accompaniment during investigations or trials, and certain assistance or subsidy mechanisms.

A victim does not need to publicly disclose private medical information to pursue legal remedies. Personally identifiable information is subject to statutory confidentiality and media-reporting restrictions.

---

11. Civil Compensation and Protective Measures

In addition to criminal proceedings, a victim may consider a civil claim for losses caused by the unlawful conduct. Depending on the evidence, recoverable damages may include:

• Medical and testing expenses;
• Future treatment expenses;
• Counseling and psychological-recovery costs;
• Lost wages or reduced earning capacity;
• Necessary transportation and care expenses;
• Compensation for emotional distress.

The availability of a restraining or protection order depends on the relationship between the parties, subsequent conduct, and the requirements of the Domestic Violence Prevention Act, Stalking and Harassment Prevention Act, or other applicable legislation. A protection order is not automatically available in every sexual-assault case, but police and prosecutors may adopt safety or confidentiality measures where legally appropriate.

➠Victims should obtain individualized legal advice before signing a settlement, confidentiality agreement, withdrawal document, or waiver of civil claims.

Frequently Asked Questions

1. Can Sexual Assault and STI Transmission in Taiwan lead to multiple criminal charges?

Yes, but multiple charges are not automatic. Prosecutors must prove the elements of each alleged offense, including lack of consent, knowledge of infection, concealment, criminal intent, and medical causation. The court must also determine whether the charges involve one act under Article 55 or several offenses subject to combined punishment under Article 51.

2. Does an STI diagnosis prove who transmitted the infection?

No. A diagnosis establishes the presence of an infection, but not necessarily the source, transmission date, or responsible person. Historical testing, incubation periods, treatment records, genetic or epidemiological evidence, and expert opinions may be required.

3. Is every person living with HIV required to disclose their status in all circumstances?

Article 21 concerns specific conduct: knowingly concealing HIV-positive status and engaging in legally defined unsafe sexual behavior or sharing injection equipment, resulting in infection or satisfying the requirements for an attempt. Liability should not be inferred from HIV status alone.

4. Does using a condom automatically eliminate criminal liability?

Not necessarily. The effect depends on the alleged offense and the facts. Barrier protection may be relevant to medical risk and the application of HIV legislation, but it does not establish consent and does not automatically resolve every criminal-law issue.

5. If the sexual activity was consensual, can an infection-related offense still be investigated?

Yes. Consent to sexual activity and informed knowledge concerning infection are separate issues. A consensual encounter may still raise an HIV-specific or injury allegation if the statutory elements are supported by evidence.

6. Can the police examine private messages and medical records?

Investigators may seek relevant digital or medical evidence through lawful procedures. The permissible scope depends on the legal authority, warrant, consent, relevance, and privacy protections involved. Parties should not delete or alter records after learning of an investigation.

7. Can a victim claim compensation before the criminal case ends?

A victim may discuss civil claims and available procedural options with counsel even while the criminal investigation is pending. The appropriate timing depends on evidence, limitation periods, litigation strategy, and whether settlement discussions are underway.

8. Should an accused person contact the complainant to explain the situation?

Usually not without first obtaining legal advice. Direct contact may be misunderstood as pressure, intimidation, evidence interference, or an attempt to influence testimony. Communications should be handled carefully and lawfully.

---

Conclusion🚨

An allegation combining sexual assault and infection cannot be resolved by applying every severe criminal provision at once. The investigation must distinguish consent, age, knowledge, concealment, medical causation, criminal intent, and the legal relationship between possible offenses.

For victims, early medical care, evidence preservation, safety planning, and privacy protection are essential. For accused persons, the priorities are obtaining legal advice, preserving complete records, avoiding speculative statements, and ensuring that medical and digital evidence is interpreted accurately.

Chien Sheng International Law Office reminds readers that this article provides general legal information only. It does not guarantee any result and cannot replace advice based on the evidence in an individual case. Anyone facing a police interview, prosecutorial summons, medical-causation dispute, or civil claim should seek assistance from a criminal lawyer as early as possible.
