Background: Acute febrile illness (AFI)is specified as sudden onset of fever of unknown
origin lasting for 1-14 days. AFI may be caused by pathogens like bacteria, viruses,
parasites, and fungi leading to infectious diseases. Dengue is a vector-borne viral disease
that is transmitted by Aedes aegypti mosquitoes. Dengue NS1 Ag is released into the
blood during viral replication in infected patients and is detectable from the first day
after fever. As NS1 Ag can be identified promptly, it acts as a beneficial biomarker for
the early detection of dengue, allowing rapid management of dengue fever.
Materials and Methods: A retrospective study was carried out on blood samples of
patients presenting with acute febrile illness in OPD/IPD of a tertiary care hospital from
September 2019- December 2019. Out of 694 samples, the samples which were 2 mL in
quantity, non-hemolytic, non-lipemic, maintained in cold chain along with complete
demographic data were selected for the present study i.e. n=270.
Results: Blood samples of 270 patients who presented with acute febrile illness and met
with our inclusion criteria were tested for dengue NS1 antigen/IgM antibodies based on
their fever history. Out of 270, 120 patients tested positive for dengue.
Conclusion: To conclude, patients in tropical countries presenting in the post-monsoon
season with acute febrile illness not responding to appropriate and adequate therapy
aimed for a suspected tropical infection such as dengue should be evaluated for
concurrent infections with other microorganisms.

Background: One of the common gastro-intestinal parasites worldwide is Blastocystis. Diverse
subtypes are employed to detect this microscopic parasite but there is not enough information on
the issue if these su-btypes may exhibit diverse clinical symptoms or not. This research aimed at
the evaluation of the clinical symptoms of the disease like itching and gastro-intestinal symptoms
in various subtypes as well as in Blastocystis co-infection with other parasites.
Methods: We extracted DNA from the fecal specimens of the cases that had been referred to the
Center for Tropical Diseases in Verona-Italy. Moreover, real-time PCR (RT PCR) was employed
to identify the available parasitic infections and nested PCR to detect the subtypes. Then, SPSS
was used to analyze data.
Results: Any significant relationship did not exist between the subtypes and clinical symptoms. In
addition, co-infection did not significantly related to the disease symptoms and a number of
parasites. The small statistical population may influence such results.
Conclusion: Further investigations must be conducted for determining the effects of Blastocystis
sub-types and their co-infection on the disease symptoms.

Background:A mysterious pneumonia case was first reported in Wuhan, China in December 2019. The World Health Organization (WHO) later named this pneumonia Coronavirus Disease (Covid-19) caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus. The massive spread of Covid-19 increases the risk of co-infection with other pre-existing pathogens including malaria
Case Report: A 32 years old woman was admitted to the hospital due to complaints of jaundice, fever, dyspneu and andominal pain. On further examination of the malaria smear, plasmodium falciparum was found in the form of trophozoites and gametocytes, the parasite count was 119,902 U/L and a nasopharyngeal PCR swab was positive for SARS CoV-2. The patient conditionimprove after administering artesunate and oseltamivir.
Discussion: Several clinical manifestations are overlapping between Covid-19 and malaria, especially extrapulmonary manifestations of Covid-19 infection, including thrombocytopenia, elevated transaminase enzymes, increased bilirubin, and impaired kidney function. Management was carried out to deal with malaria and Covid-19 simultaneously and continuously.
