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 chara...cteristics 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)

On 27 September 2024, the Ministry of Health of Rwanda confirmed the country’s first outbreak of Marburg virus disease (MVD), with health-care workers in Kigali particularly affected. While sporadic outbreaks have occurred in various parts of Africa since the first recognized cases in 1967, this o...utbreak is the third largest outbreak of MVD ever recorded to date. Marburg virus disease is a severe disease clinically similar to Ebola disease. With no approved treatments or vaccines for MVD, early intervention for those showing symptoms is crucial for improving survival rates.

The waves of yellow fever transmission in the Region of the Americas in 2016–2018 involved the largest number of human and epizootic cases to be reported in several decades. Yellow fever is a serious viral hemorrhagic disease that poses a challenge for health professionals. It requires early recog...nition of signs and symptoms, which are often nonspecific, and it can mimic other acute febrile syndromes. Early detection of suspected or confirmed cases, monitoring of vital signs, life support measures, and treatment of acute kidney failure continue to be the recommended strategies for case management. This report is the result of discussions among experienced specialists in the Americas on the clinical management of yellow fever patients, especially during outbreaks and epidemics, in the context of current medical and scientific evidence and taking into account the technical guidelines already available in the countries of the Region. It includes flowcharts for initially addressing patients with clinical suspicion of yellow fever and proposes a minimum package of laboratory tests that may be useful in contexts where resources are limited. In addition, it considers aspects of health system organization for dealing with yellow fever outbreaks and epidemics.

19 August 2022. A monkeypox case investigation form (CIF) has been designed as a tool for Member States and researchers to conduct in-depth epidemiological investigation of suspected, probable and confirmed cases of monkeypox. This form allows to collect data prospectively or retrospectively for bot...h 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.

On 31st December 2019, the World Health Organization (WHO) China Country Office was informed of cases of pneumonia of unknown etiology (unknown cause) detected in Wuhan City, Hubei Province of China. On 7th January 2020, Chinese authorities identified a new strain of Coronavirus as the causative age...nt for the disease. The virus has been renamed by WHO as SARS-CoV-2 and the disease caused by it as COVID-19. The disease since its first detection in China has now spread to over 200 countries/territories, with reports of local transmission happening in more than 160 of these countries/territories. As per WHO (as of 1st April, 2020), there has been a total of 823626 confirmed cases and 40598 deaths due to COVID-19 worldwide.
In India, as on 2nd April, 2020, 1965 confirmed cases (including 51 foreign nationals) and 50 deaths reported from 29 States/UTs. Large number of cases has been reported from Delhi, Karnataka, Kerala, Maharashtra, Rajasthan, Tamil Nadu, Telangana and Uttar Pradesh.

India reported its 1st case of COVID-19 on 30th January, 2020. It was a travel related case from Wuhan, China. Since then (as on 29th March, 2020), 979 confirmed cases and 25 deaths have been reported from 27 States/UTs. Although there is no evidence to widespread community transmission, 20 existing... and 22 potential hotspots have been identified. The containment measures to break the cycle of transmission and clinical management of those affected would require large human resource (HR).

Diphtheria in the Americas -Summary of the situation.
In 2018, three countries in the Region of the Americas (Colombia, Haiti, and the Bolivarian Republic of Venezuela) reported confirmed cases of diphtheria. In 2019, Haiti and Venezuela reported confirmed cases.
7 April 2022. Aimed at national policymakers, public health and healthcare planners, staff working in reception centres, and healthcare staff caring for displaced persons, the information note concludes that universal testing of incoming refugees from Ukraine for tuberculosis (TB) infection is not r...ecommended. Specific groups, such as household contacts of bacteriologically confirmed pulmonary cases, or those who are immunocompromised should however be considered for TB infection testing.
