The spread of Severe Acute Respiratory Syndrome - Coronavirus 2 (SARS-CoV-2) continues to progress, causing damage in several countries of the world due to its rapid transmissibility and significant mortality rates, despite government measures to contain its tra...nsmission, such as movement control, the closing of schools, bans on travel and public gatherings, the mandatory use
of masks, and hand hygiene. The coronavirus disease (COVID-19) has clinical manifestations that are similar to those found in other infections also transmitted through the airways, such as pulmonary tuberculosis (TB) Although TB is a global health problem, it is a curable disease, with affordable treatment and prevention. Nonetheless, it remains one of the leading
causes of death from a single infectious agent worldwide, a situation threatened by COVID-19.

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

This Rapid Advice Guideline updates the Interim Guidance on the “Assessment of infants with microcephaly in the context of Zika virus” published in February 2016 (WHO/ZIKV/MOC/16.3). The recommendations provides guidance on the screening, clinical assessment, neuroimaging, laboratory investigati...on and follow-up of children born to women living in areas of Zika virus transmission. The Guideline summarises the evidence base and rationale in support of the recommendations and expands the scope to address complications beyond microcephaly and what is now referred to as the congenital Zika virus syndrome
