Surveillance, case investigation and contact tracing for monkeypox: interim guidance 24 June 2022
recommended
The overall goal of surveillance, case investigation and contact tracing in this context is to stop human-to-human transmission to control the outbreak. The key objectives of surveillance and
...
case investigation are to rapidly identify cases and clusters in order to provide optimal clinical care; to isolate cases to prevent further transmission; to identify, manage and follow up contacts to recognize early signs of infection; to protect frontline health workers; to identify risk groups; and to tailor effective control and prevention measures.

The WHO publication “Surveillance, case investigation and contact tracing for mpox: interim guidance” provides updated global technical guidance on monitoring and responding to mpox (formerly k
...
nown as monkeypox). It explains how countries should conduct surveillance to detect new outbreaks, carry out case investigation including clinical assessment and lab specimen collection, and perform contact tracing to monitor people exposed to confirmed or probable cases in order to stop transmission and protect at-risk groups. The guidance includes practical recommendations for how long contacts should be monitored (e.g., daily for 21 days without requiring quarantine if symptom-free) and advising good hygiene and reduced exposure risk during the monitoring period. This interim guidance is intended to support public health authorities worldwide in strengthening mpox outbreak detection, response, and reporting.

Household transmission investigation protocol for 2019-novel coronavirus (2019-nCoV) infection
recommended
The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is

intended to provide rapid and early information on the clinical, epidemiological and virological characteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)

investigation of suspected, probable and confirmed cases of monkeypox. This form allows to collect data prospectively or retrospectively for both cases and their contacts. The full form is meant to serve as a tool for in-country use and the data are not required to be reported to WHO.

k.
Results: We identified 90 suspected LF cases of which 19 were confirmed by the laboratory. More than half (52.6%) of the confirmed cases were females with majority (73.7%) in the age group ≥ 15 years. The Case Fatality Rate (CFR) of 63.2% among the laboratory-confirmed positive cases where 9 of 19 cases died, was significantly higher compared to the laboratory confirmed negative cases where 6 of the 65 cases died ( CFR; 8.5%) p ≤ 0.05. Two hundred and eighty-seven contacts of the confirmed cases were identified, out of which 267(93.0%) completed the follow-up without developing any symptoms and 2 (0.7%) developed symptoms consistent with LF and were confirmed by the laboratory. More than half of the contacts were females (64.5%) with most of them (89.2%) in the age group ≥ 25 years. more
