NCT06840860

Brief Summary

This study aims to better understand how mpox is spreading in the DRC, how it affects different groups of people, and how well vaccines protect against it. The study is designed as a cross-sectional survey, meaning researchers will collect and analyze data from patients diagnosed with mpox at a single point in time. It will also use a case-control approach, comparing people who test positive for the virus to those who test negative, to identify risk factors and evaluate the effectiveness of the vaccine.

Sampling MethodNon-Probability Sample
Study Population

The study will take place in the DRC, in the provinces most affected by mpox in recent months, namely North Kivu, South Kivu, Maniema, Kinshasa and Equateur. The study could be extended to other provinces, depending on the dynamics of the epidemic and research needs. Participants will be recruited from general referral hospitals (HGR) and from referral health centers (CSR) or health centers (CS) in the most affected areas, which provide mpox screening and management services.

You may qualify if:

  • Apply to be tested for VMPX at HGR or another test center.
  • Patients of all ages and sexes. However, minors under the age of 12 are excluded from questions on sex life.
  • The patient or his/her culturally acceptable representative is willing and able to give informed consent for participation in the study.

Biospecimen

Retention: SAMPLES WITH DNA

Venous blood: A maximum 10mL tube blood will be taken by venipuncture from adult participants and children aged 5 and over, while dried blood drops (DBS) will be used for children under 5 and babies. Skin Lesion swab: Skin swabs will be collected following the standard operating procedures of the national program, INRB and CDC recommendations; the base of the lesion is swabbed with a dry sterile flocked nylon swab. A single swab is used for sampling at least two separate lesions in two different locations on the body Oropharyngeal swab: Dry, flocked nylon swabs are used to swab the middle part of the throat, just beyond the tongue
