Infectious disease outbreaks have long posed a public health threat, especially in Africa, where the incidence of infectious outbreaks has risen exponentially. Although, Africa has witnessed several outbreaks of emerging and re-emerging infectious diseases such as Ebola virus disease and other epidemic-prone diseases, little attention has been given towards strengthening the health surveillance systems. However, the recent COVID-19 pandemic has uncovered the region's already due to inefficient and ineffective health surveillance systems. However, the impact posed by the COVID-19 pandemic on health systems in the region has been catastrophic, it has also stressed the importance of rethinking and focusing on lessons learned during the COVID-19 pandemic. In this paper, we examine how Africa's poor disease surveillance systems affected the responses and strategies aimed at COVID-19 containment. To ensure early disease outbreak identification and prompt public health interventions in Africa, the current disease surveillance and response mechanisms must be strengthened.

Summary: In addition to the overwhelming and uncontrollable second wave of COVID‐19 in India, the country is also dealing with an outbreak of mucormycosis, a deadly fungal infection, which is affecting thousands of COVID‐19 patients. With the increasing number of cases of mucormycosis and a fatality rate of 50%, many Indian states and union territories have declared an epidemic of black fungus due to its unprecedented emergence, which has adversely affected the already debilitated health system of the country. The advent of the new fungal epidemic in the country is due to the overdosage, panic and injudicious use of corticosteroids among COVID‐19 patients, as well as their pre‐existing medical history of diabetes, given that India is the diabetes capital of the world. Thus, there is an urgent need to address this public health concern by having nationwide surveillance, diagnostic and management system of the disease, along with public awareness and education to combat the syndemic of COVID‐19 and mucormycosis in the country.

The Philippines, a disaster-prone country in Asia, was hit by 22 tropical cyclones during the coronavirus disease (COVID-19) pandemic. Among the 22 tropical cyclones, 1 is recorded as the strongest tropical cyclone that made a landfall in world history. The recurrent typhoons in the Philippines during the pandemic have led to a long-lasting humanitarian crisis as hundreds of thousands of houses and collateral assets have been destroyed due to floods and landslides, leaving thousands of Filipinos homeless. Concurrently, the country has been experiencing a rise in the number of COVID-19 cases due to overcrowding in evacuation centers and lack of social distancing. The simultaneous existence of natural disasters and pandemic has caused devastating and detrimental effects to the mental health of Filipinos. Nonetheless, the Government of the Philippines, together with the World Health Organization and other humanitarian organizations, has been working hand-in-hand in implementing mental health approaches and providing psychological interventions to Filipinos who were greatly affected by the natural disasters and the COVID-19 pandemic.

In February 2021, a new Ebola outbreak occurred amid the coronavirus disease 2019 (COVID-19) pandemic in the Republic of Guinea. Technical committees and Ebola mitigation mechanisms used during the 2014-2016 Ebola epidemics, have been redeployed by the public health organizations and African health organizations. As the burden on the local healthcare system is rising, fears of socioeconomic disruption are growing as well. Strategies used during the previous epidemic need to be reactivated, and new measures taken during the challenges of COVID-19 are being considered. This perspective discusses the available evidence regarding the epidemic of Ebola in Guinea amid the COVID-19 pandemic, highlights the challenges to be prioritized, and provides evidence-based recommendations.

It is already widely known that the COVID‐19 pandemic has added a heavy burden to the health care system in different parts of the world. In Brazil, the situation was no different. The uncontrolled increase in the contagion curve of the disease has tested the limits of the country's health system. This situation is aggravated by the coexistence of an outbreak of Chikungunya, which affects mainly the most vulnerable groups in the country. The overlap of these two crises can be a dangerous combination if urgent measures are not taken.
