In the SF Bay Area there is a 7 county stay in place order and linked to essential services in the community. There is a shortage of N95 masks and Test Kits.
The key to not spreading the disease is self-containment until we can test everyone and isolate and treat those who have it.

In the meantime I have been looking at things we can do to strengthen our immune systems so if/when we get coronavirus, our body can fight it better. These are not medical advice or recommendations, just For What Its Worth.

the first is an article on possible immune boosters by Dr Mercola
Supplements for Coronavirus Protection


the other is an abstract of a study (behind pay wall) that proposes the Keto Diet as an immune booster by itself, for the reasons that ketones boost T-Cells which fight Viruses, and second, the Keto Diet, limits Carbs (and sugars) that Viruses feed on and third, Virgin Unprocessed Coconut Oil has anti-microbial characteristics. The diet is high-fat, low-carb and is not for everyone. The calorie ratio of one version of the diet is 70% fat, 20-25% protein and 5-10% carbohydrates. There are many websites that can tell you how to get started, and libraries have books on the subject.

This is only a "mouse study" not a clinical trial, so FWIW ~

Putting mice on a keto diet
Our immune responses to infections are influenced by several extrinsic factors, including weather, social interactions, and diet. Here, Goldberg et al. report that feeding mice a high-fat, low-carbohydrate ketogenic diet confers protection in the context of lethal influenza infection. By characterizing the immune response in the lungs, the authors identified that ketogenic diet promoted the expansion of γδ T cells in the lung. Using mice lacking γδ T cells, the authors have established the functional importance of these cells in conferring protection. Their findings suggest that γδ T cells improve barrier function in the lungs by modifying differentiation and function of the airway epithelial cells.

Abstract
Influenza A virus (IAV) infection–associated morbidity and mortality are a key global health care concern, necessitating the identification of new therapies capable of reducing the severity of IAV infections. In this study, we show that the consumption of a low-carbohydrate, high-fat ketogenic diet (KD) protects mice from lethal IAV infection and disease . KD feeding resulted in an expansion of γδ T cells in the lung that improved barrier functions, thereby enhancing antiviral resistance. Expansion of these protective γδ T cells required metabolic adaptation to a ketogenic diet because neither feeding mice a high-fat, high-carbohydrate diet nor providing chemical ketone body substrate that bypasses hepatic ketogenesis protected against infection. Therefore, KD-mediated immune-metabolic integration represents a viable avenue toward preventing or alleviating influenza disease.

That's all I got so do your own DD on this diet.
I will add that Virgin Coconut Oil (or MCT oil) with its anti-microbial properties would be good to take by itself, and cutting out sugar/carbs by itself would slow down a virus so that could be good, too. Those might be small steps to start with. I have found that eating coconut oil takes away hunger and makes the diet easier.
