COVID-19 an ongoing pandemic with high transmission and mortality rate gets the researchers' attention to the disease. The disease burden on the health care system focuses on the COVID-19 impacts on the hematological and biochemical parameters. This study aimed to focus on the laboratory indicators that fluctuate in COVID-19. The single-center cross-sectional study in the pathology department of POF hospital Wah Cantt from August 2021 to December 2021. Three hundred positive COVID-19 patients were included in the study. The138 (46%) were males and 162 (54%) females and the mean age was 58 ± 15.06 (range 5 – 86). The biochemical indicator raised in COVID-19 included CPK (191.25 ± 507.39), CRP (68.81 ± 70.95), LDH (429.48 ± 246.96), and ALT (46.50 ± 43.23). In hematological parameters, only neutrophils elevated (70.00 ± 13.52) lymphocytes decreased. Laboratory parameters measured were similar values in recovered and death cases. The findings suggest the raised level of CRP, LDH, CPK, ALT, ferritin, D-Dimer, and neutrophils predict the early diagnosis and prompt treatment.

At the end of 2019, there was an outbreak of coronavirus in Wuhan, China which killed more than 1800 people and more than 70,000 people were infected during the first 5 days. Chinese researchers named it as a novel coronavirus disease 2019. Up to now, 231 million cases and more than 4 million deaths have been reported worldwide. The total number of cases of COVID cases in Pakistan was 1,236,888 so far and the total death toll was 27,500 and is increasing rapidly.  OmniPATHTM COVID-19 Total Antibody ELISA Test kit was used for serological analysis. We found that the highest number of patients with positive antibody test was Lahore with 48%. (n=442). Total antibodies against SARS-CoV-2 was found to be higher in men (43%) compared to women (41%). 13% of the children were found to be positive for SARS-CoV-2 IgG. In age wise distribution, patients in age group 41-50 year were recorded highest seroprevalance. We took the mean of antibody titer according to different age groups and we found the highest mean of antibody titer which was 171 in age group (21-30).

The arboviral infection dengue represents a global public health risk as the frequency of cases climbs across period and is anticipated to do so in the future. The fundamental mechanisms behind the concept between obesity and dengue, however, are rarely discussed. A number of variables, including the existence of cytokines that increase inflammatory response and deregulation of endothelium barrier protein production, contribute to plasma permeability, a defining feature of severe dengue. The key diabetes-related variables that impact endothelium functioning include th-1 skewed responses and the production of junctional-related proteins. Additionally, obesity affects lipid metabolism and the immune system, which increases viral multiplication and inflammatory processes. The common factor among individuals with diabetes and obesity is chronic inflammation, which results in endothelial dysfunction. Explored along with the disease's relationships with diabetes and obesity are the potential causes of comorbidities in severe dengue.
