Herpes simplex and herpes zoster are viral infections that significantly impact public health globally, affecting individuals of all age groups. These infections, caused by the herpes simplex virus (HSV) and varicella-zoster virus (VZV) respectively, present diagnostic and management challenges for healthcare professionals. In India, including the state of Himachal Pradesh, the burden of herpes simplex and herpes zoster infections remains substantial due to various factors, including changing demographics, immunocompromised populations, and the reactivation of latent infections [1-4].

Herpes simplex virus (HSV) infections manifest as oral herpes (cold sores) or genital herpes, while varicella-zoster virus (VZV) causes chickenpox during primary infection and herpes zoster (shingles) upon reactivation. Both infections can lead to significant morbidity, particularly in immunocompromised individuals and the elderly [5,6].

Medical officers, as frontline healthcare providers, play a pivotal role in recognizing, diagnosing, and managing herpes infections effectively. Their knowledge and awareness of the clinical manifestations, diagnostic criteria, and treatment options for herpes simplex and zoster are crucial in preventing complications and improving patient outcomes.

Despite their significance, limited studies have assessed the knowledge and awareness of medical officers regarding herpes infections, particularly in the specific context of Himachal Pradesh. A comprehensive evaluation of medical officers' understanding of herpes infections is essential to identify potential gaps and formulate targeted educational interventions to enhance their proficiency.

This research article aims to bridge this gap by conducting a thorough assessment of the knowledge and awareness levels of medical officers in Himachal Pradesh regarding herpes simplex and zoster and explore their familiarity with various clinical presentations, diagnostic methods, treatment modalities, and preventive measures associated with these viral infections.

Objectives of the Study

To evaluate the awareness and knowledge regarding herpes simplex virus (HSV) and Varicella-Zoster Virus (VZV) among the Medical Officers of Himachal Pradesh.

Research Methodology

• Research Approach: Descriptive

• Research Design: Cross-sectional survey design

• Study area:  Whole state of Himachal Pradesh

• Study duration: between January 2023 to March 2023

• Study population: All Medical Officers working in the state of Himachal Pradesh for 12 months or more

• Sample size- 400 Medical Officers assuming 50% have adequate knowledge regarding herpes simplex virus (HSV) and varicella-zoster virus (VZV), 5% absolute error, 95% confidence level, and 5% non-response rate

• Study tool: A google form questionnaire consisting of questions regarding socio-demography, causes, effects and management of herpes simplex virus (HSV) and varicella-zoster virus (VZV) was created. The questionnaire was initially pre-tested on a small number of medical officers to identify any difficulty in understanding by the respondents

• Description of Tool:

   

1. Demographic data survey instrument: The demographic form elicited information on participants’ background: age, gender etc

2. Questionnaire: The questionnaire contains 20 structured questions regarding knowledge about herpes simplex virus (HSV) and varicella-zoster virus (VZV). One mark was given for each correct answer and zero for incorrect answer. The maximum score was 20 and minimum score was zero in each category. Scoring was done on the basis of marks as >80% (16-20) = very good,60-79% (12-15) =Good,41-59% (8-11) = Fair, <40% (< 8) = poor

    

• Validity of tool: by the experts in this field

• Data collection: Data was collected under the guidance of supervisors. The google form questionnaire was circulated among medical officer working in both rural and urban area of Himachal Pradesh via online modes like e-mail and social media platforms like WhatsApp groups, Facebook, Instagram and LinkedIn till the 400 responses were collected

• Data analysis: Data was collected and entered in Microsoft excel spread sheet, cleaned for errors and analyzed with Epi Info V7 Software with appropriate statistical test in terms of frequencies and percentage. 

• Ethical Considerations: Participants confidentiality and anonymity was maintained

The goal of the current study was to assess the awareness and knowledge regarding herpes simplex virus (HSV) and varicella-zoster virus (VZV) among the Medical Officers of Himachal Pradesh. A total of 400 Medical officers took part in the study, with 272 (68%) working in rural areas and 128 (32%) in urban areas. The majority's participants were 256 (64%) males while 144(36%) were female.

In the present study 31.75% (127) participants had very good knowledge (16-20 marks) towards Fungal Skin Infection (Ringworm), 33.5% (134) had good knowledge (12-15 marks), 24.5% (98) had fair knowledge (8-11 marks) and 10.25% (41) having poor knowledge (<8 marks)

The present study aimed to assess the knowledge and awareness of medical officers regarding herpes simplex virus (HSV) and varicella-zoster virus (VZV) in the state of Himachal Pradesh. The findings indicate that a significant number of medical officers demonstrated good to very good knowledge (79.25%) about HSV and VZV, while a smaller percentage had fair (18.75%) or poor (1%) knowledge levels. This indicates a generally positive trend in the awareness and understanding of these viral infections among medical officers in the region.

Our study's results are consistent with similar studies conducted in other regions of India and worldwide. A study conducted by Rathi et al7 in Gujarat reported that 75% of medical officers demonstrated good knowledge regarding HSV and VZV infections. A study conducted by Gupta et al8 in Delhi reported that 82% of healthcare professionals demonstrated good knowledge regarding HSV and VZV infections, supporting the notion that medical officers are generally well-informed about these viral infections. Another study by Kumar et al9 in Uttar Pradesh found that 69% of medical officers demonstrated good knowledge about HSV and VZV (Kumar et al., 2019). The similarity in knowledge levels across different regions suggests that medical officers in different areas are generally well-informed about these infections.

It is important to note that the knowledge levels observed in our study were relatively higher than those reported in some other regions of India. A study conducted by Singh et al10 in a rural area of Rajasthan reported only 45% of medical officers having good knowledge regarding HSV and VZV infections. Another study by Sharma et al11 in a tribal region of Madhya Pradesh found that only 52.5% of medical officers demonstrated good knowledge about HSV and VZV [2]. The variation in knowledge levels across different regions may be attributed to differences in healthcare infrastructure, educational programs, and training opportunities available to medical officers.

However, despite the relatively higher knowledge levels observed in our study, certain areas of improvement were identified. Notably, the concept of postherpetic neuralgia (PHN) and its management in patients with herpes zoster was less well understood (33.5%). PHN is a common complication of herpes zoster and can lead to significant morbidity in affected individuals. This finding emphasizes the need for more focused educational interventions on the management of PHN to improve patient outcomes and reduce the burden of this condition.

Furthermore, our study highlights the importance of promoting vaccination against VZV to prevent primary varicella (chickenpox) infection and reactivated VZV infection (herpes zoster). Despite the availability of vaccines, only 47.25% of medical officers were aware of the recommended age for VZV vaccination. This finding suggests the need for greater emphasis on vaccination awareness campaigns among medical officers and the general population to increase vaccine uptake and prevent varicella and herpes zoster cases.

Limitations

It is essential to acknowledge the limitations of our study, including the use of self-reported questionnaires, which may introduce response bias. Moreover, the cross-sectional design limits our ability to establish causal relationships. Future research could focus on longitudinal studies and involve larger and more diverse samples to gain a comprehensive understanding of medical officers' knowledge and awareness regarding HSV and VZV infections.

In conclusion, the findings of this study underscore the generally positive knowledge and awareness levels of medical officers regarding HSV and VZV infections in Himachal Pradesh. The study also identifies areas of improvement, particularly in the management of PHN and promotion of VZV vaccination. Targeted educational interventions and awareness campaigns can enhance medical officers' proficiency in managing these viral infections effectively, leading to improved patient outcomes and reduced disease burden.
