“…Previous research has mostly focused on disease control and prevention mechanism ( Gao and Yu, 2020 ; Kang et al, 2020 ). The first set of research considered the epidemiology of infections ( Nkenfou et al, 2021 ; Shah et al, 2020 ). The second set of research determined the effect of various factors on epidemic prevention ( Ahmad et al, 2021 ; Yang and Ren, 2020 ).…”

The emergence of a new coronavirus (COVID-19) has become a major global concern that has damaged human health and disturbing environmental quality. Some researchers have identified a positive relationship between air pollution (fine particulate matter PM 2.5 ) and COVID-19. Nonetheless, no inclusive investigation has comprehensively examined this relationship for a tropical climate such as India. This study aims to address this knowledge gap by investigating the nexus between air pollution and COVID-19 in the ten most affected Indian states using daily observations from 9th March to September 20, 2020. The study has used the newly developed Hidden Panel Cointegration test and Nonlinear Panel Autoregressive Distributed Lag (NPARDL) model for asymmetric analysis. Empirical results illustrate an asymmetric relationship between PM 2.5 and COVID-19 cases. More precisely, a 1% change in the positive shocks of PM 2.5 increases the COVID-19 cases by 0.439%. Besides, the estimates of individual states expose the heterogeneous effects of PM 2.5 on COVID-19. The asymmetric causality test of Hatemi-J's (2011) also suggests that the positive shocks on PM 2.5 Granger-cause positive shocks on COVID19 cases. Research findings indicate that air pollution is the root cause of this outbreak; thus, the government should recognize this channel and implement robust policy guidelines to control the spread of environmental pollution.

“…One limitation of this study is related to the elimination of malaria-positive cases before arbovirus screening. Two studies reported cases of DENV/malaria co-infected children in Yaoundé, Cameroon [31,32]. Moreover, several studies around the world described cases of DENV/malaria, malaria/DENV/CHIKV and malaria/CHIKV co-infections [33,34].…”

We report the molecular evidence of dengue virus (DENV) and chikungunya virus (CHIKV) infection in symptomatic individuals in Cameroon and Gabon, respectively. Arthropod-borne viruses (arboviruses) are distributed in the tropical or subtropical regions, with DENV having the highest burden. The morbidity and mortality related to arboviral diseases raise the concern of timely and efficient surveillance and care. Our aim was to assess the circulation of arboviruses [DENV, CHIKV, Zika virus (ZIKV)] among febrile patients in Dschang (West Cameroon) and Kyé-ossi (South Cameroon, border with Gabon and Equatorial Guinea). Dried blood spots were collected from 601 consenting febrile patients, and 194 Plasmodium spp.-negative samples were tested for the molecular detection of cases of DENV, CHIKV and ZIKV infection. Overall, no case of ZIKV infection was found, whereas one case of DENV infection and one case of CHIKV infection were detected in Dschang and Kyé-ossi, respectively, with the CHIKV-infected patient being resident in Gabon. Our findings suggest the need to establish an active surveillance of arbovirus transmission in Cameroon and bordering countries.

“…Denguemalaria coinfection was firstly documented in children attending healths centers in Yaoundé [15]. Later, Nkengfou et al found a coinfection rate of 19.5% in infants consulting at the Centre Mère-Enfant in Yaounde [10]. In another study, a malaria-dengue coinfection rate of 13% was documented in the New-Bell district in Douala [14].…”

In Cameroon, recent studies have documented several cases of dengue infection in some urban areas, but dengue-malaria coinfection malaria was little investigated, especially in the East region. From the 6th July to the 4th September 2020, a case-control study including 50 cases (malaria-positive subjects) and 90 controls (non-malaria subjects) was carried out at the Bertoua Regional Hospital. Participants were prospectively enrolled and administered with a questionnaire to record information such as age, sex, dwelling place, dengue knowledge, and the environment's quality. Blood specimens were then collected and screened for dengue infection using the NS1/IgG/IgM rapid diagnostic tests and hematological parameters were measured using a MINDRAY-type hemacytometer. Of the malaria patients, 14% (7/50) were tested positive for dengue fever against 66.66% for the controls (60/90). Most malaria patients had a secondary dengue infection (57.14%, 4/7) while most of the non-malaria patients faced a primary infection (61.66%, 37/60). In both groups, women were more exposed than men to dengue and there was a significant association between the dwelling place and dengue seropositivity. Moreover, young subjects <16 years old were significantly more associated with dengue than 16-30 years old (OR=16.24, P=0.042 for cases vs, OR=21, P=0.0001 for controls). The analysis of hematological parameters showed a significant decrease (P<0.001) in platelets in cases compared to control. These results suggest that dengue fewer targets malaria- than non-malaria patients with different serological characteristics in Bertoua city. However, co-infected patients demonstrated a greater clinical vulnerability than monoinfected patients, urging the need for epidemiological surveillance.
