Infectar is a Spanish verb which translates into English as “to infect”.
Below are all of the conjugations for infectar in Spanish, in all three moods (indicative/indicativo, subjunctive/subjunctivo and imperative/imperativo) and all of the tenses, for each pronoun.
The vosotros pronoun is mainly used in mainland Spain, and is the informal second-person plural – it could be considered the Spanish version of “y’all”. It is rarely found in Latin America, where ustedes is used instead.
The vos form is used instead of tú in some Spanish speaking countries of South America, especially the Southern Cone (e.g. Argentina and Uruguay) and has a different conjugation.

The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está infectando) and past continuous (estaba infectando). The easiest way to think of it is the equivalent of english’s -ing form (e.g. infecting).
The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he infectado and hubiera infectado. These are the equivalent of English’s ‘have’ (e.g. have infected).
| Gerundio / Gerund | infectando |

| Participio / Past Participle | infectado |
The basic form of speech, el indicativo is used for making statements, talking about facts, events and things that are certain and objective.
The present tense is as it sounds – it’s for talking about things that are currently going on, which are habitual, or which generally exist. In English, this would be “I infect” or “they infect”.
| Pronoun | Spanish |
|---|---|
| Yo | infecto |
| Tú | infectas |
| Él / Ella / Usted | infecta |
| Nosotros / as | infectamos |
| Vosotros / as | infectáis |
| Ellos / Ellas / Ustedes | infectan |
| Vos | infectás |
Your simple past tense, e.g. “I infected” or “she infected” in English.
In Spanish, there are two past tenses where just one is used in English; the pretérite infefinido is typically used to refer to a concrete, specific moment in time.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | infecté | I infected |
| Tú | infectaste | You infected |
| Él / Ella / Usted | infectó | He / she / you infected |
| Nosotros / as | infectamos | We infected |
| Vosotros / as | infectasteis | You infected |
| Ellos / Ellas / Ustedes | infectaron | They / you infected |
| Vos | infectaste | You infected |
The pretérito imperfecto roughly translates as “I was infecting” or “she was infecting” in English, and is typically used to describe things and set a scene, talk about events without a specific timeframe, or talk about habitual events or states in the past.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | infectaba | I was infecting |
| Tú | infectabas | You were infecting |
| Él / Ella / Usted | infectaba | He was / she was / you were infecting |
| Nosotros / as | infectábamos | We were infecting |
| Vosotros / as | infectabais | You were infecting |
| Ellos / Ellas / Ustedes | infectaban | They / you were infecting |
| Vos | infectabas | You were infecting |
The perfect tense is for talking about things which happened in the past but are still related to the present or continue into the present.
In English, these use the auxiliary verbs ‘have’ and ‘has’ – i.e. “I have infected” and “she has infected”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | he infectado | I have infected |
| Tú | has infectado | You have infected |
| Él / Ella / Usted | ha infectado | He has / she has / you have infected |
| Nosotros / as | hemos infectado | We have infected |
| Vosotros / as | habéis infectado | You have infected |
| Ellos / Ellas / Ustedes | han infectado | They / you have infected |
| Vos | has infectado | You have infected |
The conditional is used in place of the English modal verb “would”, i.e. “I would infect” or “she would infect”. It can be used to talk about hypothetical situations.
| Pronoun | Spanish | Englush |
|---|---|---|
| Yo | infectaría | I would infect |
| Tú | infectarías | You would infect |
| Él / Ella / Usted | infectaría | He / she / you would infect |
| Nosotros / as | infectaríamos | We would infect |
| Vosotros / as | infectaríais | You would infect |
| Ellos / Ellas / Ustedes | infectarían | They / you would infect |
| Vos | infectarías | You would infect |
The future tense, simply put, replaces the English modal verb “will” – i.e. “I will infect” or “they will infect”.
It is more commonly used for making a hypothesis about the present. To talk about the future, Spanish speakers frequently use “ir + a + infinivo”, e.g. “van a infectar” means “They are going to infect”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | infectaré | I will infect |
| Tú | infectarás | You will infect |
| Él / Ella / Usted | infectará | He / she / you will infect |
| Nosotros / as | infectaremos | We will infect |
| Vosotros / as | infectaréis | You will infect |
| Ellos / Ellas / Ustedes | infectarán | They / you will infect |
| Vos | infectarás | You will infect |
| Pronoun | Spanish |
|---|---|
| Yo | infecte |
| Tú | infectes |
| Él / Ella / Usted | infecte |
| Nosotros / as | infectemos |
| Vosotros / as | infectéis |
| Ellos / Ellas / Ustedes | infecten |
| Vos | infectes |
There are two ways to form the imperfect subjunctive.
The first option sees verbs ending in -era (for -er and -ir verbs) and -ara (for -ar verbs), while the second sees verbs ending in -ese (for -er and -ir verbs) and -ase (for -ar verbs).
There is no difference between these two forms, and Spanish speakers use them interchangeably.
| Pronoun | Spanish era/ara | Spanish ese/ase |
|---|---|---|
| Yo | infectara | infectase |
| Tú | infectaras | infectase |
| Él / Ella / Usted | infectara | infectase |
| Nosotros / as | infectáramos | infectásemos |
| Vosotros / as | infectarais | infectaseis |
| Ellos / Ellas / Ustedes | infectaran | infectasen |
| Vos | infectaras | infectase |
The future subjunctive is no longer used in modern-day Spanish, apart from in literary and legal contexts, and there is no need to learn it.
It is formed the same as the past/imperfect subjunctive, but with -e endings instead of -a endings.

| Yo | infectare |
| Tú | infectares |
| Él / Ella / Usted | infectare |
| Nosotros / as | infectáremos |
