Introduction
COVID-19 infection is caused by the Severe Acute Respiratory Syndrome
Coronavirus 2 (SARS-CoV-2) virus, which has already propagated to over
210 nations and territories throughout the worldwide. The World Health
Organization (WHO) has declared it a pandemic emergency due to the rise
of COVID-19 cases in March 2020. COVID-19 was confirmed for the first
time in Bangladesh on March 8, 2020 (1). Till date, globally 190 million
cases along with over 4 million deaths have been recorded due to
COVID-19. COVID-19 infection can have a wide range of symptoms, from
mild to severe acute respiratory syndrome requiring respiratory support
(2). Hemoptysis is prevalent in about up to 13 percent of pulmonary
embolism patients and seldom seen among COVID-19 patients (3). Aside
from the continuing pandemic, dengue is predominant for the last decades
and caused high morbidity and mortality. Bangladesh has been hit by
dengue fever every year, and COVID-19 pandemic started in Bangladesh
from March, 2020 (4). Dengue fever is a viral infection caused by four
kinds of Flaviviridae viruses (DENV-1, DENV-2, DENV-3, and DENV-4).
Infected Aedes aegypti and Aedes albopictus female mosquitoes are the
most common carriers of these viruses(5). However, dengue and COVID-19
might be a hazardous combination. According to clinician observation,
many cases have been detected in different hospitals in Bangladesh. In
this report, we have presented a case of COVID-19 and dengue
co-infection in a person in Bangladesh, where the patient presented
hemoptysis as first presentation.
