Abstract

Latin America is suppose to have significant advantages over other developing regions, such as Asia and Africa, given the time where the Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), causing the Coronavirus Diseases 2019 (COVID-19), arrived, mainly from Europe. This occurred on February 26, 2020. Then, multiple previous measures were taken in order to prevent and mitigate the impact of pandemic in the region. In the current mini-review update we discuss the possibilities of “crushing” the transmission curve of COVID-19 in the region after two months of the arrival of this emerging coronavirus.

Introduction

The first confirmed case of the Severe Acute Respiratory Syndrome coronavirus 2 (SARS-Cov-2) infection, causing the Coronavirus Diseases 2019 (COVID-19) in Latin America was detected on February 26, 2020, with one case in Brazil, proceeding from Italy. As of May 3, 2020, there have been more than 248,000 confirmed cases in the Latin America and the Caribbean region (203,097 in South America) and 13,436 deaths (6,750 in Brazil)1. After analyzing the situation and comparing it with other countries and regions that have dealt with the pandemic in a correct and timely manner, we suggest some measures that may contribute to the “crushing”2 of the curve in the remaining weeks for social isolation. It would be considered mandatory in most countries that should take serious measures for that.

Suggested measures to “crushing” the curve of COVID-19 in Latin America
In order to control more, to mitigate, to slow down the speed of the transmission in the region, we have analyzed, based on multiple sources, the idea of suggestion of the following measures:

The active search for asymptomatic and symptomatic cases. The countries with the best management of the epidemic have come to take samples of the majority of their population and have not waited for a call to an emergency center to do it. The evaluation must also be active and early for targeted groups such as health personnel without exception, the armed forces, and the police, and for all workers who have continued their work during the period of compulsory isolation, especially those serving the public, such as the staff of supermarkets, pharmacies and the like3.

The application of chest CT without contrast both in groups at risk of developing severe forms of the disease or transmitting the infection to others through their work activity, this would help us to know the true state of “asymptomatic” or of “Pre-symptomatic” that appear to be two completely different situations4,5.

The imaging follow-up of all the isolates, through health brigades that perform a pulmonary ultrasound, who can verify day by day the favorable evolution or not of the lung lesions and decide to keep them in isolation or transfer them to a health center6.

Isolation of all positive cases by RT-PCR, rapid test, or suggestive chest tomography must be strict and in one-person settings for a minimum of 14 days. This mandatory isolation of cases cannot be in the patient’s home or with other positive cases, because it has already been described that overexposure to the virus is a risk factor for poor evolution, with compliance control of the mandatory isolation through geolocation (GPS)7. For this purpose, hotels that are currently empty in the different cities of the region or sports venues can be equipped, such as the sports village of Peru, built for the Pan American Games, currently little occupied. These areas of isolation can also be used by health professionals who do not want to be in contact with their families because they are afraid of infecting them.

Their authorities must fully protect health personnel facing this pandemic through legal initiatives that include: declaration of occupational disease, respect for their employment status, employment contracts for new and old with all the benefits of law without distinction, the creation of life insurance thought and calculated to cover the family and relatives in case of death or complications for the rest of life 8.

It is important for the evaluation and follow-up of all the recovered cases before the possibility of the use of their antibodies, the evaluation of the viral load, and the knowledge of the pathophysiology of the disease 9,10there are no approved specific antiviral agents for novel coronavirus disease 2019 (COVID-19.

Implement areas with negative pressure where aerosol-generating procedures are carried out, and the continuous supply of personal protective equipment for health personnel must be guaranteed. We must aspire to follow the highest international standards in this regard. In essence, the use of certified N95 respirators must be massive by health personnel, and in areas where aerosols are produced, at least FPP3 respirators must be used11 .

We must not neglect the general population. Therefore we must carry out massive educational campaigns on the correct use of masks in public places, in addition to the well-known cough hygiene measures, social distancing, and voluntary isolation in case of symptoms 7.

Actively evaluate people over 60 or with comorbidities in their homes, rest homes, nursing homes, shelters, and centers for the elderly. The personnel in charge of their care must be periodically evaluated through RT-PCR, and rapid tests and external visits must be restricted. The use of masks should be mandatory for caregivers12.

“Clean” hospitals should be designated to centralize pediatrics, gynecology, urgent surgeries, and medicine, transferring to them patients who cannot be discharged and who do not have an infection, being evaluated by general practitioners or specialists not related to caring of patients with COVID-19. Hospitals with intensive care units and mechanical ventilators and qualified personnel for their use will receive patients with COVID-1913  the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Besides, it is also important to have a personal and protocolized medical history for patients with COVID-19 that serves for rapid decision-making and better case management14.

DISCUSSION

We still have time to implement many of the measures that protect our region. We are optimistic, and we believe that if governments continue to listen to the voices of the academy, they will be able to make the curve “crushed” very soon. Countries in the region, such as Brazil 15, are facing a critical situation as the pandemic advance, given the massive number of cases reported week after week. But in others, as is the case of Ecuador, the number of fatalities, coupled with the lack of intensive care units (ICU) beds, seems to be critical for the health care, as well as complex with the overlapping of other epidemics, such as dengue16.

Multiple implications related to healthcare situation at the arrival of this pandemic disease, including other epidemics, such as malaria and measles, related to Venezuela forced migration, highlight the complex crisis of the region17,18.

Finally, we need to increase the diagnostic capacity in the region, in order to increase the number of RT-PCR for SARS-CoV-2 performed in order to better approach to the real epidemiological situation of Latin America19,20. Whilst we wait an effective vaccine, the best control is preventive measures, as those suggested in this mini-review20.
