While COVID-19 (coronavirus disease 2019) is an important emergent issue for all in the country, there is a significant number of people in the population who are especially vulnerable to the potential impact that the novel coronavirus epidemic may have on their health. The overall purpose of the study is to investigate: (1) the dynamics of COVID-19 infection among people living with HIV and health care workers providing HIV services; (2) the provision of HIV and HIV/TB care and treatment services at health facilities, within the scope of COVID-19 or in the context of COVID-19 and; (3) the perceptions of COVID-19 and access to care among people living with HIV and health care workers providing HIV services.
The protocol is designed to assess prevalence and incidence of COVID-19 among PLHIV and
health care workers. Additionally, we aim to evaluate the effect of the COVID-19 epidemic on
clinical and immunological outcomes and health care service delivery among PLHIV and HCWs
providing HIV services in Mozambique, as well as monitoring breakthrough infections after
vaccination. This will facilitate timely estimates of transmissibility of SARS-CoV-2, and of
the severity of COVID-19 infection among PLHIV and HCWs providing HIV services, as well as
inform public health responses to these vulnerable populations. In Mozambique, this is
particularly important as health systems are operating at capacity, and resources to expand
services in the country are limited. It is in this context that a novel respiratory pathogen,
SARS-CoV-2, could have a potentially severe impact in Mozambique among its estimated 2.2
million HIV-infected persons and the health care providers caring for them. The study
protocol will be implemented at national level in up to 11 provinces of Mozambique. Results
will be used primarily for program improvement and strengthening and will support the
Ministry of Health in the decision making on strategies for the COVID-19 response.
Goal The overarching goal of this protocol is to determine the incidence, prevalence, and
clinical manifestations of SARS-CoV-2 among patients living with HIV and healthcare workers
providing HIV services, and to assess the knowledge, attitudes and practices (KAP) and the
impact that COVID-19 has on them and on the healthcare system.
Objectives Primary Objectives
1. To determine the incidence and prevalence of SARS-CoV-2 among unvaccinated PLHIV
enrolled in care.
2. To describe the knowledge, attitudes, practices and perceived risks (KAP-P) regarding
SARS-CoV-2, prevention, transmission, and management among PLHIV and HCWs providing HIV
services.
3. To evaluate the effect of COVID-19 pandemic on retention to HIV care.
Secondary Objectives
1. To determine the clinical, immunologic, and virological outcomes of SARS-CoV-2 infection
in PLHIV and HCWs providing HIV care.
2. To describe the perceptions of PLHIV and HCWs providing HIV services regarding the
influence that the COVID-19 pandemic has on the delivery of essential services
(including HIV/TB care).
3. To measure the fidelity of participating health facilities to the implementation of
national COVID-19 guidelines.
4. To describe COVID-19 breakthrough infection among vaccinated PLHIV and health care
workers (HCW) providing HIV care.
Inclusion Criteria:
1. PLHIV enrolled in HIV care
- Have HIV infection and currently in follow-up care at selected HFs;
- Aged 18 years or older;
- Able and willing to give informed consent;
- Willing to test for exposure to SARS-CoV-2 or COVID-19 infection;
- Willing to be followed and to comply with study visits during the maximum of
15-month study period;
- Does not intend to move from their residence (requiring change of health facility
for HIV care) during the study period;
- Willing and able to provide contact information.
2. HCWs offering HIV services
- HCWs (medical doctor, medical officer ["técnico de medicina"], general nurse
["agente de medicina"], maternal and child health [MCH] nurse, pharmacist,
laboratory worker, counselor, ancillary worker [e.g., archivist, receptionist],
and health volunteers based at the health facility) who are employed full-time
and offering HIV services at selected HFs;
- ≥18 years of age ;
- Able and willing to give informed consent;
- Be vaccinated with at least one dose against COVID-19 (verbally or vaccination
card));
- Willing to test for exposure to SARS-CoV-2/ COVID-19 infection;
- Willing to be followed and available during the maximum of 15-month study period;
- Does not intend to transfer to another HF during the study period;
- Willing and able to provide contact information.
Exclusion Criteria:
1. PLHIV enrolled in HIV care
- Any clinical or mental condition that, in the investigator's opinion, would
preclude provision of informed consent or make study participation unsafe or
unethical;
- Any Differentiated Service Delivery where patients have an ART pick-up scheduled
less frequently than four times a year (e.g., Community Adherence Support Group
[CASG] member);
- Patients whose antiretroviral (ARV) drugs are picked up by a confidant during
their scheduled appointment.
2. HCWs offering HIV services
- Any clinical or mental conditions that, in the opinion of the investigator or
designee, would preclude provision of informed consent or make study
participation unsafe or unethical;
- Individuals working in the HF but from the following cadres: drivers, security
personnel, and community health workers/volunteers.
