COVID-19 and arboviral diseases: Another challenge for Pakistan's dilapidated healthcare system Dear Editor,

The impact of the co-epidemics of coronavirus disease 2019 and other infectious diseases 1-3 on an already delipidated healthcare system in Pakistan has been highlighted recently in a few studies 4, 5 ; this enormous decimation continues to rise. The current pandemic of COVID-19 caused by novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as of October 30, 2020, has reached 219 countries, taken more than 1 million lives, and has 44.5 million confirmed cases around the globe. 6,7 In Pakistan, the number of COVID-19 cases is escalating rapidly (328,602 cases), with the death toll crossing 6000 so far. 7 Simultaneously with the devastating effect of COVID-19 on health facilities, co-concurrence of other viral infections, including dengue, chikungunya, and Zika, might become a significant public health issue in Pakistan in the coming days. However, it has been confirmed that Pakistan is endemic to arboviral infection, as shown in Figure 1A ,B, 8 Catastrophic effects were reported in Latin America 9,10 and Asia, 5, 11, 12 where SARS CoV-2 outbreaks occurred during the dengue seasonal transmission period.

The latest study from Brazil indicates that dengue, chikungunya, and Zika have undergone a major upsurge during the COVID-19 pandemic season. 13 In the early stage of the disease, arbovirus infection (dengue, chikungunya, Zika) and COVID-19 exhibit similar clinical and laboratorial manifestations, thereby rendering the diagnoses more difficult. 14 Dreadfully, in serological testing, false-positive results have been identified as dengue fever, later verified as COVID-19. [14] [15] [16] Consequently, the misdiagnosis has impaired appropriate management and treatment of patients, thus increasing the prevalence of the disease with adverse clinical outcomes. 17 Pakistan is the world's fifth most populated country with a population of over 216 million; surprisingly, since 1995, its population has grown by 176 million. 18 As a result of an abrupt growth rate of 2.04%, 19 the demand for resources has also risen. This led to rapid unplanned urbanization along with potential health risks, stagnant water, drainage blocks, and waste dumps. These are the most favorable conditions for the propagation of multiple arboviral infections. 20 Pakistan's healthcare sector is currently faced with chronic low-funding problems, massive workforce shortage, ineffective operational coordination, and medical equipment constraints.

Appallingly, Pakistan has never planned to deal with major public health crises, which have doubled in response to COVID-19 outbreaks. Quarantine and lockdowns, an essential prevention measure for the pandemic, may have contributed to an upsurge in outbreaks of arboviruses. During this lockdown, the population lives close together for a long time, which facilitate breeding for arthropods/mosquitoes in and around houses. 17 The high prevalence of arboviruses in developing and low-income countries such as Pakistan, which have insufficient access to sanitation, closed water supply, and hygiene, raises the risk of vector reproduction and, therefore, increased arboviral infections, which is of grave concern while concomitant with COVID- 19. 21 In view of this trend of arboviral infections worldwide, Pakistan's healthcare sector is now at high risk for potential outbreaks. Provincial public health authorities must also not overlook other emergent arboviral pathogens already present in Pakistan before the arrival of co-epidemics. The authorities must actively enforce vector control programs and segregation of patients to avoid further upswings of vector-borne disease. Failure to continue screening programs for concurrent diseases and sensible allocation of new funding and facilities to COVID-19 could have severe ramifications for Pakistan due to the healthcare system's downturn.
