I had a risk relationship where I practiced oral sex and the next day I had some symptoms. Can I have an acute HIV infection?

Hello, Dr. I had a risk relationship where I practiced active oral sex (mouth / vagina). The next day I had a headache, an upset stomach, a lump in my neck, and a bad smell coming from my throat. I do not think I had a fever. If I had, it was very low ... I consulted an otolaryngologist who did not see any infection, did a fibroscopy and a sign of gastroesophageal reflux. My blood count consisted of lymphocytosis. In 30 days I had a 3rd generation HIV test and it was negative. Taking into account the immunological window and the symptoms described above, would I be with an acute phase of HIV or would it be another pathology?
Expert answer:

If you had a relationship in which you practiced unprotected oral sexthere is a risk of having been infected by the virus HIV.

Not always in the acute phase of HIV there is a presence of symptoms and, when there is, usually only after 2 to 4 weeks in which the contagion occurred. Between 10 and 60% of people can stay up to 6 months without presenting any symptoms of the infection.

The symptoms of the acute phase of HIV are non-specific and may include:

  • Fever;
  • Fatigue;
  • Increased lymph nodes;
  • Sore throat;
  • Weight loss;
  • Muscle aches;
  • Headache;
  • Nausea;
  • Night sweats;
  • Diarrhea;
  • Skin rash (blemishes on the skin).

It is important to remember that the presence of these symptoms does not mean that you have HIV. Other common diseases such as flu, viruses and throat infections can manifest the same signs and symptoms.

The immunological window (period in which the person has the virus in the body but it is not detected in the exams) can last between 4 and 10 weeks after exposure to risk.

At this time you present the negative test, you should continue to pay attention to your body, possible symptoms and seek medical advice if necessary.
